Here is the caller graph for this function:

◆ setGeometry()

void QFbWindow::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.

Reimplemented from QPlatformWindow.

Definition at line 29 of file qfbwindow.cpp.
