The component layout needs to be re-calculated. For some reason it is with
the Qt backend but not with GL.
Either way we can force it to re-calculate when the component changes.
It possibly doesn't get dirty when the dependencies are deleted.
Remove the intermediate properties for width and height and - just like
qt backend - apply the width and height in apply_window_properties
and when receiving a window resize event.
This also elimiates the get_geometry() getter as that would otherwise just
have been a FIXME'ed default().
* Provide an internal behavior parameter to run_event_loop() that we can use
from the preview to not quit when the last window was closed.
* Fix Drop for the winit event loop GraphicsWindow to drop the backend window correctly
when unmapping, not when the graphics window dies. Otherwise QuitOnLastWindowClosed doesn't work.
This way we can serve preview requests immediately.
This basically makes post_event safe to call before the event loop is entered.
The events will be queued up and sent when the event loop
is created and we have access
to the proxy, which will take over the queue.
* sixtyfps_timer_start needs to *take* the timer id out of the Rust
timer to avoid that the subsequent drop stops the timer again
* For the Qt event loop, call `timer_event()` once before entering
QCoreApplication::exec(), to schedule any timers that were started
beforehand.
* Added a way to quit the event loop gently, in order to use that
from the C++ unit test.
Similar to the window properties, use a property tracker with a change
handler in window to issue redraw requests. This allows eliminating the
forced repaints in the event loop after event processing and ensures
that the UI is repainted when programmatically setting a property, for
example.
Synchronize title/background/etc. once when the window is mapped and
afterwards lazily when the corresponding property tracker notifies us.
Since that callback can happen at any point in time and to also capture
potentially multiple changes, this first triggers a wakeup of the event
loop, when the actual application of properties happens.
By default PropertyTracker::evaluate() registers the currently
evaluating binding/tracker as a dependency. This should help with
repeaters and other scenarios where in the run-time we use property
trackers but want to track the overall "dirtyness" in the window with
regards to whether a redraw is needed or not.
The new evaluate_as_dependency_root() function allows skipping this
mechanism and is used for the two trackers in the window.
Try adding an LC_RPATH command to the cdylib that we're building (for example libsixtyfps_cpp.dylib),
to fix linkage against Qt, which uses `@rpath/QtCore.framework/XXX` for inter-library linkage dependencies.
Remove the `application` infix from `register_application_font`, to
reduce the changes that it might be interpreted to be a function that
also changes the default font in all text elements.
Since colorize property force the native item to be a ClippedImage, it had
a source rectangle, despite with and height defaulting to 0 and therefore
having an empty source rect would cause the scaling to not be right
Have a function first called before the children, and then the main function
called after the children if they did not accept the event. This will allow
processing the Flickable gesture properly
