		const QRect &	initialGeometry,
		int	defaultWidth,
		int	defaultHeight,
		const QScreen **	resultingScreenReturn = `nullptr`
	)

static

Helper function to get initial geometry on windowing systems which do not do smart positioning and also do not provide a means of centering a transient window w.r.t. its parent. For example this is useful on Windows and MacOS but not X11, because an X11 window manager typically tries to layout new windows to optimize usage of the available desktop space. However if the given window already has geometry which the application has initialized, it takes priority.

initialGeometry has to be provided in native pixels. defaultWidth has to be provided in device independent pixels defaultHeight has to be provided in device independent pixels

◆ requestActivateWindow()

void QPlatformWindow::requestActivateWindow ( )

virtual

Reimplement to let Qt be able to request activation/focus for a window

Some window systems will probably not have callbacks for this functionality, and then calling QWindowSystemInterface::handleWindowActivated(QWindow *w) would be sufficient.

If the window system has some event handling/callbacks then call QWindowSystemInterface::handleWindowActivated(QWindow *w) when the window system gives the notification.

Default implementation calls QWindowSystem::handleWindowActivated(QWindow *w)

Reimplemented in QXcbWindow, QWindowsWindow, QWasmWindow, QQnxWindow, QOffscreenWindow, QIOSWindow, QHaikuWindow, QEglFSWindow, QCocoaWindow, and QAndroidPlatformWindow.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ requestUpdate()

void QPlatformWindow::requestUpdate ( )

virtual

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 5 ms. The additional time is there to give the event loop a bit of idle time to gather system events.

Here is the caller graph for this function:

◆ screenForGeometry()

QPlatformScreen * QPlatformWindow::screenForGeometry ( const QRect & newGeometry ) const

protected

Helper function for finding the new screen for newGeometry in response to a geometry changed event. Returns the new screen if the window was moved to another virtual sibling. If the screen changes, the platform plugin should call QWindowSystemInterface::handleWindowScreenChanged().

Note: : The current screen will always be returned for child windows since they should never signal screen changes.

Reimplemented in QWindowsWindow, and QCocoaWindow.

Definition at line 534 of file qplatformwindow.cpp.

Here is the call graph for this function:

◆ setGeometry()

void QPlatformWindow::setGeometry ( const QRect & rect )

virtual

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.
