(2) supported with EGL only (not GLX) - - 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) - - - LICENSE - ======= - zlib/libpng license - - Copyright (c) 2018 Andre Weissflog - - This software is provided 'as-is', without any express or implied warranty. - In no event will the authors be held liable for any damages arising from the - use of this software. - - Permission is granted to anyone to use this software for any purpose, - including commercial applications, and to alter it and redistribute it - freely, subject to the following restrictions: - - 1.
