void QWasmWindow::requestUpdate ( )

overridevirtual

Requests an QEvent::UpdateRequest event.

The event will be delivered to the QWindow.

QPlatformWindow subclasses can re-implement this function to provide display refresh synchronized updates. The event should be delivered using QPlatformWindow::deliverUpdateRequest() to not get out of sync with the internal state of QWindow.

The default implementation posts an UpdateRequest event to the window after an interval that is at most 5 ms. If the window's associated screen reports a \l{QPlatformScreen::refreshRate()}{refresh rate} higher than 60 Hz, the interval is scaled down to a valid smaller than 5. The additional time is there to give the event loop a bit of idle time to gather system events.

◆ setGeometry()

void QWasmWindow::setGeometry ( const QRect & rect )

overridevirtual

This function is called by Qt whenever a window is moved or resized using the QWindow API.

Unless you also override QPlatformWindow::geometry(), you need to call the baseclass implementation of this function in any override of QPlatformWindow::setGeometry(), as QWindow::geometry() is expected to report back the set geometry until a confirmation (or rejection) of the new geometry comes back from the window manager and is reported via QWindowSystemInterface::handleGeometryChange().

Window move/resizes can also be triggered spontaneously by the window manager, or as a response to an earlier requested move/resize via the Qt APIs. There is no need to call this function from the window manager callback, instead call QWindowSystemInterface::handleGeometryChange().

The position(x, y) part of the rect might be inclusive or exclusive of the window frame as returned by frameMargins(). You can detect this in the plugin by checking qt_window_private(window())->positionPolicy.
