+ 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_GLES2
+ #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_LOG(msg) - your own logging function (default: puts(msg))
+ SOKOL_UNREACHABLE() - a guard macro for unreachable code (default: assert(false))
+ SOKOL_ABORT() - called after an unrecoverable error (default: abort())
+ 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: -)
+ SOKOL_CALLOC - your own calloc function (default: calloc(n, s))
+ SOKOL_FREE - your own free function (default: free(p))
+
+ 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.
+
+ For example code, see https://github.com/floooh/sokol-samples/tree/master/sapp
+
+ Portions of the Windows and Linux GL initialization and event 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: 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 -dxguid
+
+ 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
+
+ Building for UWP requires a recent Visual Studio toolchain and Windows SDK
+ (at least VS2019 and Windows SDK 10.0.19041.0). When the UWP backend is
+ selected, the sokol_app.h implementation must be compiled as C++17.
+
+ On macOS and iOS, the implementation must be compiled as Objective-C.
+
+ FEATURE OVERVIEW
+ ================
+ sokol_app.h provides a minimalistic cross-platform API which
+ implements the 'application-wrapper' parts of a 3D application:
+
+ - a common application entry function
+ - creates a window and 3D-API context/device with a 'default framebuffer'
+ - makes the rendered frame visible
+ - provides keyboard-, mouse- and low-level touch-events
+ - platforms: MacOS, iOS, HTML5, Win32, Linux, Android (TODO: RaspberryPi)
+ - 3D-APIs: Metal, D3D11, GL3.2, GLES2, GLES3, WebGL, WebGL2

+ - clipboard, mouselock
+ - sapp_consume_event() on non-web platforms?
+
+ 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,
+ ...
+ };
+ }
+
+ 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).
+
+ 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.
+ .fail_cb (void (*)(const char* msg))
+ The fail callback is called when a fatal error is encountered
+ during start which doesn't allow the program to continue.
+ Providing a callback here gives you a chance to show an error message
+ to the user. The default behaviour is SOKOL_LOG(msg)
+
+ 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_cb (void(*)(const sapp_event* event, void* user_data))
+ .fail_cb (void(*)(const char* msg, void* user_data))
+ These are the user-data versions of the callback functions. You
+ can mix those with the standard callbacks that don't have the
+ user_data argument.
+
+ 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++.
+
+ 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
+ 27 == SG_PIXELFORMAT_BGRA8
+ 41 == SG_PIXELFORMAT_DEPTH
+ 42 == SG_PIXELFORMAT_DEPTH_STENCIL
+
+ int sapp_sample_count(void)
+ Return the MSAA sample count of the default framebuffer.
+
+ bool sapp_gles2(void)
+ Returns true if a GLES2 or WebGL context has been created. This
+ is useful when a GLES3/WebGL2 context was requested but is not
+ available so that sokol_app.h had to fallback to GLES2/WebGL.
+
+ 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 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_EVENTYTPE_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,
+ .buffer_size = buf_size,
+ .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 uint32_t num_bytes = response->fetched_size;
+ // and the pointer to the data (same as 'buf' in the fetch-call):
+ const void* ptr = response->buffer_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:

+
+ 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. You can also get a DPI scaling factor with the function
+ sapp_dpi_scale().
+
+ Here's an example on a Mac with Retina display:
+
+ sapp_desc sokol_main() {
+ return (sapp_desc) {
+ .width = 640,
+ .height = 480,
+ .high_dpi = true,
+ ...
+ };
+ }
+
+ 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
+
+ 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 brower 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().
+
+ 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.
+
+ 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 UPDATE_CURSOR event currently behaves differently between Win32 and OSX
+ (Win32 sends the event each frame when the mouse moves and is inside the window
+ client area, OSX sends it only once when the mouse enters the client area)
+ - 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)
