If sokol_app.h is compiled as a DLL, define the following before
including the declaration or implementation:
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
SOKOL_DLL
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
On Windows, SOKOL_DLL will define SOKOL_API_DECL as __declspec(dllexport)
or __declspec(dllimport) as needed.
If you use sokol_app.h together with sokol_gfx.h, include both headers
in the implementation source file, and include sokol_app.h before
sokol_gfx.h since sokol_app.h will also include the required 3D-API
headers.
On Windows, a minimal 'GL header' and function loader is integrated which
contains just enough of GL for sokol_gfx.h. If you want to use your own
GL header-generator/loader instead, define SOKOL_WIN32_NO_GL_LOADER
before including the implementation part of sokol_app.h.
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
To make use of the integrated GL loader, simply include the sokol_app.h
implementation before the sokol_gfx.h implementation.

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

- 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))
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
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.
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
.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
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
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:
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
.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.
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
You can also call sapp_query_desc() to get a copy of the
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
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)
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
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.
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.
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
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
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
Objective-C ids converted with a (ARC) __bridge cast so that
the ids can be tunnel through C code. Also note that the returned
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
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
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
back with a (ARC) __bridge cast.
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
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
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
back with a (ARC) __bridge cast.
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
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.
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
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)
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
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!

2020-08-23 07:25:30 +02:00
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.
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
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
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
- a string was pasted to the system clipboard
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).
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
--- 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
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
behaviour, and how to intercept a pending quit - for instance to show a
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
"Really Quit?" dialog box). Note that the cleanup-callback isn't
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
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
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
size is 8 KBytes. Strings that don't fit into the clipboard buffer
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
(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()
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
to obtain the pasted UTF-8 encoded text.
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
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
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
================
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
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
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
application-quit-process. It's possible to initiate a 'programmatic quit'
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
from the application code, and a quit initiated by the application user can
be intercepted (for instance to show a custom dialog box).
sokol and fontstash modules
2020-01-16 20:45:47 +01:00
This 'programmatic quit protocol' is implemented trough 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.
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
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:

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).
gg: update sokol and stb_truetype
2020-08-23 07:25:30 +02:00
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.
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)
