- sokol_app.h -- cross-platform application wrapper
-
- Project URL: https://github.com/floooh/sokol
-
- Do this:
- #define SOKOL_IMPL or
- #define SOKOL_APP_IMPL
- before you include this file in *one* C or C++ file to create the
- implementation.
-
- In the same place define one of the following to select the 3D-API
- which should be initialized by sokol_app.h (this must also match
- the backend selected for sokol_gfx.h if both are used in the same
- project):
-
- #define SOKOL_GLCORE33
- #define SOKOL_GLES3
- #define SOKOL_D3D11
- #define SOKOL_METAL
- #define SOKOL_WGPU
-
- Optionally provide the following defines with your own implementations:
-
- SOKOL_ASSERT(c) - your own assert macro (default: assert(c))
- SOKOL_UNREACHABLE() - a guard macro for unreachable code (default: assert(false))
- SOKOL_WIN32_FORCE_MAIN - define this on Win32 to use a main() entry point instead of WinMain
- SOKOL_NO_ENTRY - define this if sokol_app.h shouldn't "hijack" the main() function
- SOKOL_APP_API_DECL - public function declaration prefix (default: extern)
- SOKOL_API_DECL - same as SOKOL_APP_API_DECL
- SOKOL_API_IMPL - public function implementation prefix (default: -)
-
- Optionally define the following to force debug checks and validations
- even in release mode:
-
- SOKOL_DEBUG - by default this is defined if _DEBUG is defined
-
- If sokol_app.h is compiled as a DLL, define the following before
- including the declaration or implementation:
-
- SOKOL_DLL
-
- On Windows, SOKOL_DLL will define SOKOL_APP_API_DECL as __declspec(dllexport)
- or __declspec(dllimport) as needed.
-
- On Linux, SOKOL_GLCORE33 can use either GLX or EGL.
- GLX is default, set SOKOL_FORCE_EGL to override.
-
- For example code, see https://github.com/floooh/sokol-samples/tree/master/sapp
-
- Portions of the Windows and Linux GL initialization, event-, icon- etc... code
- have been taken from GLFW (http://www.glfw.org/)
-
- iOS onscreen keyboard support 'inspired' by libgdx.
-
- Link with the following system libraries:
-
- - on macOS with Metal: Cocoa, QuartzCore, Metal, MetalKit
- - on macOS with GL: Cocoa, QuartzCore, OpenGL
- - on iOS with Metal: Foundation, UIKit, Metal, MetalKit
- - on iOS with GL: Foundation, UIKit, OpenGLES, GLKit
- - on Linux with EGL: X11, Xi, Xcursor, EGL, GL (or GLESv2), dl, pthread, m(?)
- - on Linux with GLX: X11, Xi, Xcursor, GL, dl, pthread, m(?)
- - on Android: GLESv3, EGL, log, android
- - on Windows with the MSVC or Clang toolchains: no action needed, libs are defined in-source via pragma-comment-lib
- - on Windows with MINGW/MSYS2 gcc: compile with '-mwin32' so that _WIN32 is defined
- - link with the following libs: -lkernel32 -luser32 -lshell32
- - additionally with the GL backend: -lgdi32
- - additionally with the D3D11 backend: -ld3d11 -ldxgi
-
- On Linux, you also need to use the -pthread compiler and linker option, otherwise weird
- things will happen, see here for details: https://github.com/floooh/sokol/issues/376
-
- On macOS and iOS, the implementation must be compiled as Objective-C.
-

-
- STEP BY STEP
- ============
- --- Add a sokol_main() function to your code which returns a sapp_desc structure
- with initialization parameters and callback function pointers. This
- function is called very early, usually at the start of the
- platform's entry function (e.g. main or WinMain). You should do as
- little as possible here, since the rest of your code might be called
- from another thread (this depends on the platform):
-
- sapp_desc sokol_main(int argc, char* argv[]) {
- return (sapp_desc) {
- .width = 640,
- .height = 480,
- .init_cb = my_init_func,
- .frame_cb = my_frame_func,
- .cleanup_cb = my_cleanup_func,
- .event_cb = my_event_func,
- ...
- };
- }
-
- To get any logging output in case of errors you need to provide a log
- callback. The easiest way is via sokol_log.h:
-
- #include "sokol_log.h"
-
- sapp_desc sokol_main(int argc, char* argv[]) {
- return (sapp_desc) {
- ...
- .logger.func = slog_func,
- };
- }
-
- There are many more setup parameters, but these are the most important.
- For a complete list search for the sapp_desc structure declaration
- below.
-
- DO NOT call any sokol-app function from inside sokol_main(), since
- sokol-app will not be initialized at this point.
-
- The .width and .height parameters are the preferred size of the 3D
- rendering canvas. The actual size may differ from this depending on
- platform and other circumstances. Also the canvas size may change at
- any time (for instance when the user resizes the application window,
- or rotates the mobile device). You can just keep .width and .height
- zero-initialized to open a default-sized window (what "default-size"
- exactly means is platform-specific, but usually it's a size that covers
- most of, but not all, of the display).
-
- All provided function callbacks will be called from the same thread,
- but this may be different from the thread where sokol_main() was called.
-
- .init_cb (void (*)(void))
- This function is called once after the application window,
- 3D rendering context and swap chain have been created. The
- function takes no arguments and has no return value.
- .frame_cb (void (*)(void))
- This is the per-frame callback, which is usually called 60
- times per second. This is where your application would update
- most of its state and perform all rendering.
- .cleanup_cb (void (*)(void))
- The cleanup callback is called once right before the application
- quits.
- .event_cb (void (*)(const sapp_event* event))
- The event callback is mainly for input handling, but is also
- used to communicate other types of events to the application. Keep the
- event_cb struct member zero-initialized if your application doesn't require
- event handling.
-
- As you can see, those 'standard callbacks' don't have a user_data
- argument, so any data that needs to be preserved between callbacks
- must live in global variables. If keeping state in global variables
- is not an option, there's an alternative set of callbacks with
- an additional user_data pointer argument:
-
- .user_data (void*)
- The user-data argument for the callbacks below
- .init_userdata_cb (void (*)(void* user_data))
- .frame_userdata_cb (void (*)(void* user_data))
- .cleanup_userdata_cb (void (*)(void* user_data))
- .event_userdata_cb (void(*)(const sapp_event* event, void* user_data))
-
- The function sapp_userdata() can be used to query the user_data
- pointer provided in the sapp_desc struct.
-
- You can also call sapp_query_desc() to get a copy of the
- original sapp_desc structure.
-
- NOTE that there's also an alternative compile mode where sokol_app.h
- doesn't "hijack" the main() function. Search below for SOKOL_NO_ENTRY.
-
- --- Implement the initialization callback function (init_cb), this is called
- once after the rendering surface, 3D API and swap chain have been
- initialized by sokol_app. All sokol-app functions can be called
- from inside the initialization callback, the most useful functions
- at this point are:
-
- int sapp_width(void)
- int sapp_height(void)
- Returns the current width and height of the default framebuffer in pixels,
- this may change from one frame to the next, and it may be different
- from the initial size provided in the sapp_desc struct.
-
- float sapp_widthf(void)
- float sapp_heightf(void)
- These are alternatives to sapp_width() and sapp_height() which return
- the default framebuffer size as float values instead of integer. This
- may help to prevent casting back and forth between int and float
- in more strongly typed languages than C and C++.
-
- double sapp_frame_duration(void)
- Returns the frame duration in seconds averaged over a number of
- frames to smooth out any jittering spikes.
-
- int sapp_color_format(void)
- int sapp_depth_format(void)
- The color and depth-stencil pixelformats of the default framebuffer,
- as integer values which are compatible with sokol-gfx's
- sg_pixel_format enum (so that they can be plugged directly in places
- where sg_pixel_format is expected). Possible values are:
-
- 23 == SG_PIXELFORMAT_RGBA8
- 28 == SG_PIXELFORMAT_BGRA8
- 42 == SG_PIXELFORMAT_DEPTH
- 43 == SG_PIXELFORMAT_DEPTH_STENCIL
-
- int sapp_sample_count(void)
- Return the MSAA sample count of the default framebuffer.
-
- const void* sapp_metal_get_device(void)
- const void* sapp_metal_get_renderpass_descriptor(void)
- const void* sapp_metal_get_drawable(void)
- If the Metal backend has been selected, these functions return pointers
- to various Metal API objects required for rendering, otherwise
- they return a null pointer. These void pointers are actually
- Objective-C ids converted with a (ARC) __bridge cast so that
- the ids can be tunnel through C code. Also note that the returned
- pointers to the renderpass-descriptor and drawable may change from one
- frame to the next, only the Metal device object is guaranteed to
- stay the same.
-
- const void* sapp_macos_get_window(void)
- On macOS, get the NSWindow object pointer, otherwise a null pointer.
- Before being used as Objective-C object, the void* must be converted
- back with a (ARC) __bridge cast.
-
- const void* sapp_ios_get_window(void)
- On iOS, get the UIWindow object pointer, otherwise a null pointer.
- Before being used as Objective-C object, the void* must be converted
- back with a (ARC) __bridge cast.
-
- const void* sapp_win32_get_hwnd(void)
- On Windows, get the window's HWND, otherwise a null pointer. The
- HWND has been cast to a void pointer in order to be tunneled
- through code which doesn't include Windows.h.
-
- const void* sapp_d3d11_get_device(void)
- const void* sapp_d3d11_get_device_context(void)
- const void* sapp_d3d11_get_render_target_view(void)
- const void* sapp_d3d11_get_depth_stencil_view(void)
- Similar to the sapp_metal_* functions, the sapp_d3d11_* functions
- return pointers to D3D11 API objects required for rendering,
- only if the D3D11 backend has been selected. Otherwise they
- return a null pointer. Note that the returned pointers to the
- render-target-view and depth-stencil-view may change from one
- frame to the next!
-
- const void* sapp_wgpu_get_device(void)
- const void* sapp_wgpu_get_render_view(void)
- const void* sapp_wgpu_get_resolve_view(void)
- const void* sapp_wgpu_get_depth_stencil_view(void)
- These are the WebGPU-specific functions to get the WebGPU
- objects and values required for rendering. If sokol_app.h
- is not compiled with SOKOL_WGPU, these functions return null.
-
- const void* sapp_android_get_native_activity(void);
- On Android, get the native activity ANativeActivity pointer, otherwise
- a null pointer.
-
- --- Implement the frame-callback function, this function will be called
- on the same thread as the init callback, but might be on a different
- thread than the sokol_main() function. Note that the size of
- the rendering framebuffer might have changed since the frame callback
- was called last. Call the functions sapp_width() and sapp_height()
- each frame to get the current size.
-
- --- Optionally implement the event-callback to handle input events.
- sokol-app provides the following type of input events:
- - a 'virtual key' was pressed down or released
- - a single text character was entered (provided as UTF-32 code point)
- - a mouse button was pressed down or released (left, right, middle)
- - mouse-wheel or 2D scrolling events
- - the mouse was moved
- - the mouse has entered or left the application window boundaries
- - low-level, portable multi-touch events (began, moved, ended, cancelled)
- - the application window was resized, iconified or restored
- - the application was suspended or restored (on mobile platforms)
- - the user or application code has asked to quit the application
- - a string was pasted to the system clipboard
- - one or more files have been dropped onto the application window
-
- To explicitly 'consume' an event and prevent that the event is
- forwarded for further handling to the operating system, call
- sapp_consume_event() from inside the event handler (NOTE that
- this behaviour is currently only implemented for some HTML5
- events, support for other platforms and event types will
- be added as needed, please open a github ticket and/or provide
- a PR if needed).
-
- NOTE: Do *not* call any 3D API rendering functions in the event
- callback function, since the 3D API context may not be active when the
- event callback is called (it may work on some platforms and 3D APIs,
- but not others, and the exact behaviour may change between
- sokol-app versions).
-
- --- Implement the cleanup-callback function, this is called once
- after the user quits the application (see the section
- "APPLICATION QUIT" for detailed information on quitting
- behaviour, and how to intercept a pending quit - for instance to show a
- "Really Quit?" dialog box). Note that the cleanup-callback isn't
- guaranteed to be called on the web and mobile platforms.
-
- MOUSE CURSOR TYPE AND VISIBILITY
- ================================
- You can show and hide the mouse cursor with
-
- void sapp_show_mouse(bool show)
-
- And to get the current shown status:
-
- bool sapp_mouse_shown(void)
-
- NOTE that hiding the mouse cursor is different and independent from
- the MOUSE/POINTER LOCK feature which will also hide the mouse pointer when
- active (MOUSE LOCK is described below).
-
- To change the mouse cursor to one of several predefined types, call
- the function:
-
- void sapp_set_mouse_cursor(sapp_mouse_cursor cursor)
-
- Setting the default mouse cursor SAPP_MOUSECURSOR_DEFAULT will restore
- the standard look.
-
- To get the currently active mouse cursor type, call:
-
- sapp_mouse_cursor sapp_get_mouse_cursor(void)
-
- MOUSE LOCK (AKA POINTER LOCK, AKA MOUSE CAPTURE)
- ================================================
- In normal mouse mode, no mouse movement events are reported when the
- mouse leaves the windows client area or hits the screen border (whether
- it's one or the other depends on the platform), and the mouse move events
- (SAPP_EVENTTYPE_MOUSE_MOVE) contain absolute mouse positions in
- framebuffer pixels in the sapp_event items mouse_x and mouse_y, and
- relative movement in framebuffer pixels in the sapp_event items mouse_dx
- and mouse_dy.
-
- To get continuous mouse movement (also when the mouse leaves the window
- client area or hits the screen border), activate mouse-lock mode
- by calling:
-
- sapp_lock_mouse(true)
-
- When mouse lock is activated, the mouse pointer is hidden, the
- reported absolute mouse position (sapp_event.mouse_x/y) appears
- frozen, and the relative mouse movement in sapp_event.mouse_dx/dy
- no longer has a direct relation to framebuffer pixels but instead
- uses "raw mouse input" (what "raw mouse input" exactly means also
- differs by platform).
-
- To deactivate mouse lock and return to normal mouse mode, call
-
- sapp_lock_mouse(false)
-
- And finally, to check if mouse lock is currently active, call
-
- if (sapp_mouse_locked()) { ... }
-
- On native platforms, the sapp_lock_mouse() and sapp_mouse_locked()
- functions work as expected (mouse lock is activated or deactivated
- immediately when sapp_lock_mouse() is called, and sapp_mouse_locked()
- also immediately returns the new state after sapp_lock_mouse()
- is called.
-
- On the web platform, sapp_lock_mouse() and sapp_mouse_locked() behave
- differently, as dictated by the limitations of the HTML5 Pointer Lock API:
-
- - sapp_lock_mouse(true) can be called at any time, but it will
- only take effect in a 'short-lived input event handler of a specific
- type', meaning when one of the following events happens:
- - SAPP_EVENTTYPE_MOUSE_DOWN
- - SAPP_EVENTTYPE_MOUSE_UP
- - SAPP_EVENTTYPE_MOUSE_SCROLL
- - SAPP_EVENTTYPE_KEY_UP
- - SAPP_EVENTTYPE_KEY_DOWN
- - The mouse lock/unlock action on the web platform is asynchronous,
- this means that sapp_mouse_locked() won't immediately return
- the new status after calling sapp_lock_mouse(), instead the
- reported status will only change when the pointer lock has actually
- been activated or deactivated in the browser.
- - On the web, mouse lock can be deactivated by the user at any time
- by pressing the Esc key. When this happens, sokol_app.h behaves
- the same as if sapp_lock_mouse(false) is called.
-
- For things like camera manipulation it's most straightforward to lock
- and unlock the mouse right from the sokol_app.h event handler, for
- instance the following code enters and leaves mouse lock when the
- left mouse button is pressed and released, and then uses the relative
- movement information to manipulate a camera (taken from the
- cgltf-sapp.c sample in the sokol-samples repository
- at https://github.com/floooh/sokol-samples):
-
- static void input(const sapp_event* ev) {
- switch (ev->type) {
- case SAPP_EVENTTYPE_MOUSE_DOWN:
- if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) {
- sapp_lock_mouse(true);
- }
- break;
-
- case SAPP_EVENTTYPE_MOUSE_UP:
- if (ev->mouse_button == SAPP_MOUSEBUTTON_LEFT) {
- sapp_lock_mouse(false);
- }
- break;
-
- case SAPP_EVENTTYPE_MOUSE_MOVE:
- if (sapp_mouse_locked()) {
- cam_orbit(&state.camera, ev->mouse_dx * 0.25f, ev->mouse_dy * 0.25f);
- }
- break;
-
- default:
- break;
- }
- }
-
- CLIPBOARD SUPPORT
- =================
- Applications can send and receive UTF-8 encoded text data from and to the
- system clipboard. By default, clipboard support is disabled and
- must be enabled at startup via the following sapp_desc struct
- members:
-
- sapp_desc.enable_clipboard - set to true to enable clipboard support
- sapp_desc.clipboard_size - size of the internal clipboard buffer in bytes
-
- Enabling the clipboard will dynamically allocate a clipboard buffer
- for UTF-8 encoded text data of the requested size in bytes, the default
- size is 8 KBytes. Strings that don't fit into the clipboard buffer
- (including the terminating zero) will be silently clipped, so it's
- important that you provide a big enough clipboard size for your
- use case.
-
- To send data to the clipboard, call sapp_set_clipboard_string() with
- a pointer to an UTF-8 encoded, null-terminated C-string.
-
- NOTE that on the HTML5 platform, sapp_set_clipboard_string() must be
- called from inside a 'short-lived event handler', and there are a few
- other HTML5-specific caveats to workaround. You'll basically have to
- tinker until it works in all browsers :/ (maybe the situation will
- improve when all browsers agree on and implement the new
- HTML5 navigator.clipboard API).
-
- To get data from the clipboard, check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED
- event in your event handler function, and then call sapp_get_clipboard_string()
- to obtain the pasted UTF-8 encoded text.
-
- NOTE that behaviour of sapp_get_clipboard_string() is slightly different
- depending on platform:
-
- - on the HTML5 platform, the internal clipboard buffer will only be updated
- right before the SAPP_EVENTTYPE_CLIPBOARD_PASTED event is sent,
- and sapp_get_clipboard_string() will simply return the current content
- of the clipboard buffer
- - on 'native' platforms, the call to sapp_get_clipboard_string() will
- update the internal clipboard buffer with the most recent data
- from the system clipboard
-
- Portable code should check for the SAPP_EVENTTYPE_CLIPBOARD_PASTED event,
- and then call sapp_get_clipboard_string() right in the event handler.
-
- The SAPP_EVENTTYPE_CLIPBOARD_PASTED event will be generated by sokol-app
- as follows:
-
- - on macOS: when the Cmd+V key is pressed down
- - on HTML5: when the browser sends a 'paste' event to the global 'window' object
- - on all other platforms: when the Ctrl+V key is pressed down
-
- DRAG AND DROP SUPPORT
- =====================
- PLEASE NOTE: the drag'n'drop feature works differently on WASM/HTML5
- and on the native desktop platforms (Win32, Linux and macOS) because
- of security-related restrictions in the HTML5 drag'n'drop API. The
- WASM/HTML5 specifics are described at the end of this documentation
- section:
-
- Like clipboard support, drag'n'drop support must be explicitly enabled
- at startup in the sapp_desc struct.
-
- sapp_desc sokol_main() {
- return (sapp_desc) {
- .enable_dragndrop = true, // default is false
- ...
- };
- }
-
- You can also adjust the maximum number of files that are accepted
- in a drop operation, and the maximum path length in bytes if needed:
-
- sapp_desc sokol_main() {
- return (sapp_desc) {
- .enable_dragndrop = true, // default is false
- .max_dropped_files = 8, // default is 1
- .max_dropped_file_path_length = 8192, // in bytes, default is 2048
- ...
- };
- }
-
- When drag'n'drop is enabled, the event callback will be invoked with an
- event of type SAPP_EVENTTYPE_FILES_DROPPED whenever the user drops files on
- the application window.
-
- After the SAPP_EVENTTYPE_FILES_DROPPED is received, you can query the
- number of dropped files, and their absolute paths by calling separate
- functions:
-
- void on_event(const sapp_event* ev) {
- if (ev->type == SAPP_EVENTTYPE_FILES_DROPPED) {
-
- // the mouse position where the drop happened
- float x = ev->mouse_x;
- float y = ev->mouse_y;
-
- // get the number of files and their paths like this:
- const int num_dropped_files = sapp_get_num_dropped_files();
- for (int i = 0; i < num_dropped_files; i++) {
- const char* path = sapp_get_dropped_file_path(i);
- ...
- }
- }
- }
-
- The returned file paths are UTF-8 encoded strings.
-
- You can call sapp_get_num_dropped_files() and sapp_get_dropped_file_path()
- anywhere, also outside the event handler callback, but be aware that the
- file path strings will be overwritten with the next drop operation.
-
- In any case, sapp_get_dropped_file_path() will never return a null pointer,
- instead an empty string "" will be returned if the drag'n'drop feature
- hasn't been enabled, the last drop-operation failed, or the file path index
- is out of range.
-
- Drag'n'drop caveats:
-
- - if more files are dropped in a single drop-action
- than sapp_desc.max_dropped_files, the additional
- files will be silently ignored
- - if any of the file paths is longer than
- sapp_desc.max_dropped_file_path_length (in number of bytes, after UTF-8
- encoding) the entire drop operation will be silently ignored (this
- needs some sort of error feedback in the future)
- - no mouse positions are reported while the drag is in
- process, this may change in the future
-
- Drag'n'drop on HTML5/WASM:
-
- The HTML5 drag'n'drop API doesn't return file paths, but instead
- black-box 'file objects' which must be used to load the content
- of dropped files. This is the reason why sokol_app.h adds two
- HTML5-specific functions to the drag'n'drop API:
-
- uint32_t sapp_html5_get_dropped_file_size(int index)
- Returns the size in bytes of a dropped file.
-
- void sapp_html5_fetch_dropped_file(const sapp_html5_fetch_request* request)
- Asynchronously loads the content of a dropped file into a
- provided memory buffer (which must be big enough to hold
- the file content)
-
- To start loading the first dropped file after an SAPP_EVENTTYPE_FILES_DROPPED
- event is received:
-
- sapp_html5_fetch_dropped_file(&(sapp_html5_fetch_request){
- .dropped_file_index = 0,
- .callback = fetch_cb
- .buffer = {
- .ptr = buf,
- .size = sizeof(buf)
- },
- .user_data = ...
- });
-
- Make sure that the memory pointed to by 'buf' stays valid until the
- callback function is called!
-
- As result of the asynchronous loading operation (no matter if succeeded or
- failed) the 'fetch_cb' function will be called:
-
- void fetch_cb(const sapp_html5_fetch_response* response) {
- // IMPORTANT: check if the loading operation actually succeeded:
- if (response->succeeded) {
- // the size of the loaded file:
- const size_t num_bytes = response->data.size;
- // and the pointer to the data (same as 'buf' in the fetch-call):
- const void* ptr = response->data.ptr;
- }
- else {
- // on error check the error code:
- switch (response->error_code) {
- case SAPP_HTML5_FETCH_ERROR_BUFFER_TOO_SMALL:
- ...
- break;
- case SAPP_HTML5_FETCH_ERROR_OTHER:
- ...
- break;
- }
- }
- }
-
- Check the droptest-sapp example for a real-world example which works
- both on native platforms and the web:
-
- https://github.com/floooh/sokol-samples/blob/master/sapp/droptest-sapp.c
-
- HIGH-DPI RENDERING
- ==================
- You can set the sapp_desc.high_dpi flag during initialization to request
- a full-resolution framebuffer on HighDPI displays. The default behaviour
- is sapp_desc.high_dpi=false, this means that the application will
- render to a lower-resolution framebuffer on HighDPI displays and the
- rendered content will be upscaled by the window system composer.
-
- In a HighDPI scenario, you still request the same window size during
- sokol_main(), but the framebuffer sizes returned by sapp_width()
- and sapp_height() will be scaled up according to the DPI scaling
- ratio.
-
- Note that on some platforms the DPI scaling factor may change at any
- time (for instance when a window is moved from a high-dpi display
- to a low-dpi display).
-
- To query the current DPI scaling factor, call the function:
-
- float sapp_dpi_scale(void);
-
- For instance on a Retina Mac, returning the following sapp_desc
- struct from sokol_main():
-
- sapp_desc sokol_main() {
- return (sapp_desc) {
- .width = 640,
- .height = 480,
- .high_dpi = true,
- ...
- };
- }
-
- ...the functions the functions sapp_width(), sapp_height()
- and sapp_dpi_scale() will return the following values:
-
- sapp_width: 1280
- sapp_height: 960
- sapp_dpi_scale: 2.0
-
- If the high_dpi flag is false, or you're not running on a Retina display,
- the values would be:
-
- sapp_width: 640
- sapp_height: 480
- sapp_dpi_scale: 1.0
-
- If the window is moved from the Retina display to a low-dpi external display,
- the values would change as follows:
-
- sapp_width: 1280 => 640
- sapp_height: 960 => 480
- sapp_dpi_scale: 2.0 => 1.0
-
- Currently there is no event associated with a DPI change, but an
- SAPP_EVENTTYPE_RESIZED will be sent as a side effect of the
- framebuffer size changing.
-
- Per-monitor DPI is currently supported on macOS and Windows.
-
- APPLICATION QUIT
- ================
- Without special quit handling, a sokol_app.h application will quit
- 'gracefully' when the user clicks the window close-button unless a
- platform's application model prevents this (e.g. on web or mobile).
- 'Graceful exit' means that the application-provided cleanup callback will
- be called before the application quits.
-
- On native desktop platforms sokol_app.h provides more control over the
- application-quit-process. It's possible to initiate a 'programmatic quit'
- from the application code, and a quit initiated by the application user can
- be intercepted (for instance to show a custom dialog box).
-
- This 'programmatic quit protocol' is implemented through 3 functions
- and 1 event:
-
- - sapp_quit(): This function simply quits the application without
- giving the user a chance to intervene. Usually this might
- be called when the user clicks the 'Ok' button in a 'Really Quit?'
- dialog box
- - sapp_request_quit(): Calling sapp_request_quit() will send the
- event SAPP_EVENTTYPE_QUIT_REQUESTED to the applications event handler
- callback, giving the user code a chance to intervene and cancel the
- pending quit process (for instance to show a 'Really Quit?' dialog
- box). If the event handler callback does nothing, the application
- will be quit as usual. To prevent this, call the function
- sapp_cancel_quit() from inside the event handler.
- - sapp_cancel_quit(): Cancels a pending quit request, either initiated
- by the user clicking the window close button, or programmatically
- by calling sapp_request_quit(). The only place where calling this
- function makes sense is from inside the event handler callback when
- the SAPP_EVENTTYPE_QUIT_REQUESTED event has been received.
- - SAPP_EVENTTYPE_QUIT_REQUESTED: this event is sent when the user
- clicks the window's close button or application code calls the
- sapp_request_quit() function. The event handler callback code can handle
- this event by calling sapp_cancel_quit() to cancel the quit.
- If the event is ignored, the application will quit as usual.
-
- On the web platform, the quit behaviour differs from native platforms,
- because of web-specific restrictions:
-
- A `programmatic quit` initiated by calling sapp_quit() or
- sapp_request_quit() will work as described above: the cleanup callback is
- called, platform-specific cleanup is performed (on the web
- this means that JS event handlers are unregisters), and then
- the request-animation-loop will be exited. However that's all. The
- web page itself will continue to exist (e.g. it's not possible to
- programmatically close the browser tab).
-
- On the web it's also not possible to run custom code when the user
- closes a browser tab, so it's not possible to prevent this with a
- fancy custom dialog box.
-
- Instead the standard "Leave Site?" dialog box can be activated (or
- deactivated) with the following function:
-
- sapp_html5_ask_leave_site(bool ask);
-
- The initial state of the associated internal flag can be provided
- at startup via sapp_desc.html5_ask_leave_site.
-
- This feature should only be used sparingly in critical situations - for
- instance when the user would loose data - since popping up modal dialog
- boxes is considered quite rude in the web world. Note that there's no way
- to customize the content of this dialog box or run any code as a result
- of the user's decision. Also note that the user must have interacted with
- the site before the dialog box will appear. These are all security measures
- to prevent fishing.
-
- The Dear ImGui HighDPI sample contains example code of how to
- implement a 'Really Quit?' dialog box with Dear ImGui (native desktop
- platforms only), and for showing the hardwired "Leave Site?" dialog box
- when running on the web platform:
-
- https://floooh.github.io/sokol-html5/wasm/imgui-highdpi-sapp.html
-
- FULLSCREEN
- ==========
- If the sapp_desc.fullscreen flag is true, sokol-app will try to create
- a fullscreen window on platforms with a 'proper' window system
- (mobile devices will always use fullscreen). The implementation details
- depend on the target platform, in general sokol-app will use a
- 'soft approach' which doesn't interfere too much with the platform's
- window system (for instance borderless fullscreen window instead of
- a 'real' fullscreen mode). Such details might change over time
- as sokol-app is adapted for different needs.
-
- The most important effect of fullscreen mode to keep in mind is that
- the requested canvas width and height will be ignored for the initial
- window size, calling sapp_width() and sapp_height() will instead return
- the resolution of the fullscreen canvas (however the provided size
- might still be used for the non-fullscreen window, in case the user can
- switch back from fullscreen- to windowed-mode).
-
- To toggle fullscreen mode programmatically, call sapp_toggle_fullscreen().
-
- To check if the application window is currently in fullscreen mode,
- call sapp_is_fullscreen().
-
- WINDOW ICON SUPPORT
- ===================
- Some sokol_app.h backends allow to change the window icon programmatically:
-
- - on Win32: the small icon in the window's title bar, and the
- bigger icon in the task bar
- - on Linux: highly dependent on the used window manager, but usually
- the window's title bar icon and/or the task bar icon
- - on HTML5: the favicon shown in the page's browser tab
-
- NOTE that it is not possible to set the actual application icon which is
- displayed by the operating system on the desktop or 'home screen'. Those
- icons must be provided 'traditionally' through operating-system-specific
- resources which are associated with the application (sokol_app.h might
- later support setting the window icon from platform specific resource data
- though).
-
- There are two ways to set the window icon:
-
- - at application start in the sokol_main() function by initializing
- the sapp_desc.icon nested struct
- - or later by calling the function sapp_set_icon()
-
- As a convenient shortcut, sokol_app.h comes with a builtin default-icon
- (a rainbow-colored 'S', which at least looks a bit better than the Windows
- default icon for applications), which can be activated like this:
-
- At startup in sokol_main():
-
- sapp_desc sokol_main(...) {
- return (sapp_desc){
- ...
- icon.sokol_default = true
- };
- }
-
- Or later by calling:
-
- sapp_set_icon(&(sapp_icon_desc){ .sokol_default = true });
-
- NOTE that a completely zero-initialized sapp_icon_desc struct will not
- update the window icon in any way. This is an 'escape hatch' so that you
- can handle the window icon update yourself (or if you do this already,
- sokol_app.h won't get in your way, in this case just leave the
- sapp_desc.icon struct zero-initialized).
-
- Providing your own icon images works exactly like in GLFW (down to the
- data format):
-
- You provide one or more 'candidate images' in different sizes, and the
- sokol_app.h platform backends pick the best match for the specific backend
- and icon type.
-
- For each candidate image, you need to provide:
-
- - the width in pixels
- - the height in pixels
- - and the actual pixel data in RGBA8 pixel format (e.g. 0xFFCC8844
- on a little-endian CPU means: alpha=0xFF, blue=0xCC, green=0x88, red=0x44)
-
- For instance, if you have 3 candidate images (small, medium, big) of
- sizes 16x16, 32x32 and 64x64 the corresponding sapp_icon_desc struct is setup
- like this:
-
- // the actual pixel data (RGBA8, origin top-left)
- const uint32_t small[16][16] = { ... };
- const uint32_t medium[32][32] = { ... };
- const uint32_t big[64][64] = { ... };
-
- const sapp_icon_desc icon_desc = {
- .images = {
- { .width = 16, .height = 16, .pixels = SAPP_RANGE(small) },
- { .width = 32, .height = 32, .pixels = SAPP_RANGE(medium) },
- // ...or without the SAPP_RANGE helper macro:
- { .width = 64, .height = 64, .pixels = { .ptr=big, .size=sizeof(big) } }
- }
- };
-
- An sapp_icon_desc struct initialized like this can then either be applied
- at application start in sokol_main:
-
- sapp_desc sokol_main(...) {
- return (sapp_desc){
- ...
- icon = icon_desc
- };
- }
-
- ...or later by calling sapp_set_icon():
-
- sapp_set_icon(&icon_desc);
-
- Some window icon caveats:
-
- - once the window icon has been updated, there's no way to go back to
- the platform's default icon, this is because some platforms (Linux
- and HTML5) don't switch the icon visual back to the default even if
- the custom icon is deleted or removed
- - on HTML5, if the sokol_app.h icon doesn't show up in the browser
- tab, check that there's no traditional favicon 'link' element
- is defined in the page's index.html, sokol_app.h will only
- append a new favicon link element, but not delete any manually
- defined favicon in the page
-
- For an example and test of the window icon feature, check out the the
- 'icon-sapp' sample on the sokol-samples git repository.
-
- ONSCREEN KEYBOARD
- =================
- On some platforms which don't provide a physical keyboard, sokol-app
- can display the platform's integrated onscreen keyboard for text
- input. To request that the onscreen keyboard is shown, call
-
- sapp_show_keyboard(true);
-
- Likewise, to hide the keyboard call:
-
- sapp_show_keyboard(false);
-
- Note that on the web platform, the keyboard can only be shown from
- inside an input handler. On such platforms, sapp_show_keyboard()
- will only work as expected when it is called from inside the
- sokol-app event callback function. When called from other places,
- an internal flag will be set, and the onscreen keyboard will be
- called at the next 'legal' opportunity (when the next input event
- is handled).
-
- OPTIONAL: DON'T HIJACK main() (#define SOKOL_NO_ENTRY)
- ======================================================
- In its default configuration, sokol_app.h "hijacks" the platform's
- standard main() function. This was done because different platforms
- have different main functions which are not compatible with
- C's main() (for instance WinMain on Windows has completely different
- arguments). However, this "main hijacking" posed a problem for
- usage scenarios like integrating sokol_app.h with other languages than
- C or C++, so an alternative SOKOL_NO_ENTRY mode has been added
- in which the user code provides the platform's main function:
-
- - define SOKOL_NO_ENTRY before including the sokol_app.h implementation
- - do *not* provide a sokol_main() function
- - instead provide the standard main() function of the platform
- - from the main function, call the function ```sapp_run()``` which
- takes a pointer to an ```sapp_desc``` structure.
- - ```sapp_run()``` takes over control and calls the provided init-, frame-,
- shutdown- and event-callbacks just like in the default model, it
- will only return when the application quits (or not at all on some
- platforms, like emscripten)
-
- NOTE: SOKOL_NO_ENTRY is currently not supported on Android.
-
- WINDOWS CONSOLE OUTPUT
- ======================
- On Windows, regular windowed applications don't show any stdout/stderr text
- output, which can be a bit of a hassle for printf() debugging or generally
- logging text to the console. Also, console output by default uses a local
- codepage setting and thus international UTF-8 encoded text is printed
- as garbage.
-
- To help with these issues, sokol_app.h can be configured at startup
- via the following Windows-specific sapp_desc flags:
-
- sapp_desc.win32_console_utf8 (default: false)
- When set to true, the output console codepage will be switched
- to UTF-8 (and restored to the original codepage on exit)
-
- sapp_desc.win32_console_attach (default: false)
- When set to true, stdout and stderr will be attached to the
- console of the parent process (if the parent process actually
- has a console). This means that if the application was started
- in a command line window, stdout and stderr output will be printed
- to the terminal, just like a regular command line program. But if
- the application is started via double-click, it will behave like
- a regular UI application, and stdout/stderr will not be visible.
-
- sapp_desc.win32_console_create (default: false)
- When set to true, a new console window will be created and
- stdout/stderr will be redirected to that console window. It
- doesn't matter if the application is started from the command
- line or via double-click.
-
- MEMORY ALLOCATION OVERRIDE
- ==========================
- You can override the memory allocation functions at initialization time
- like this:
-
- void* my_alloc(size_t size, void* user_data) {
- return malloc(size);
- }
-
- void my_free(void* ptr, void* user_data) {
- free(ptr);
- }
-
- sapp_desc sokol_main(int argc, char* argv[]) {
- return (sapp_desc){
- // ...
- .allocator = {
- .alloc = my_alloc,
- .free = my_free,
- .user_data = ...,
- }
- };
- }
-
- If no overrides are provided, malloc and free will be used.
-
- This only affects memory allocation calls done by sokol_app.h
- itself though, not any allocations in OS libraries.
-
-
- ERROR REPORTING AND LOGGING
- ===========================
- To get any logging information at all you need to provide a logging callback in the setup call
- the easiest way is to use sokol_log.h:
-
- #include "sokol_log.h"
-
- sapp_desc sokol_main(int argc, char* argv[]) {
- return (sapp_desc) {
- ...
- .logger.func = slog_func,
- };
- }
-
- To override logging with your own callback, first write a logging function like this:
-
- void my_log(const char* tag, // e.g. 'sapp'
- uint32_t log_level, // 0=panic, 1=error, 2=warn, 3=info
- uint32_t log_item_id, // SAPP_LOGITEM_*
- const char* message_or_null, // a message string, may be nullptr in release mode
- uint32_t line_nr, // line number in sokol_app.h
- const char* filename_or_null, // source filename, may be nullptr in release mode
- void* user_data)
- {
- ...
- }
-
- ...and then setup sokol-app like this:
-
- sapp_desc sokol_main(int argc, char* argv[]) {
- return (sapp_desc) {
- ...
- .logger = {
- .func = my_log,
- .user_data = my_user_data,
- }
- };
- }
-
- The provided logging function must be reentrant (e.g. be callable from
- different threads).
-
- If you don't want to provide your own custom logger it is highly recommended to use
- the standard logger in sokol_log.h instead, otherwise you won't see any warnings or
- errors.
-
-
- TEMP NOTE DUMP
- ==============
- - onscreen keyboard support on Android requires Java :(, should we even bother?
- - sapp_desc needs a bool whether to initialize depth-stencil surface
- - GL context initialization needs more control (at least what GL version to initialize)
- - application icon
- - the Android implementation calls cleanup_cb() and destroys the egl context in onDestroy
- at the latest but should do it earlier, in onStop, as an app is "killable" after onStop
- on Android Honeycomb and later (it can't be done at the moment as the app may be started
- again after onStop and the sokol lifecycle does not yet handle context teardown/bringup)

- Q: Why not use CAMetalDrawable.presentedTime on macOS and iOS?
- A: The value appears to be highly unstable during the first few
- seconds, sometimes several frames are dropped in sequence, or
- switch between 120 and 60 Hz for a few frames. Simply measuring
- and averaging the frame time yielded a more stable frame duration.
- Maybe switching to CVDisplayLink would yield better results.
- Until then just measure the time.
