Here is the call graph for this function:
|
overridevirtual |
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::handleFocusWindowChanged(QWindow *w) would be sufficient.
If the window system has some event handling/callbacks then call QWindowSystemInterface::handleFocusWindowChanged(QWindow *w) when the window system gives the notification.
Default implementation calls QWindowSystem::handleFocusWindowChanged(QWindow *w)
Reimplemented from QPlatformWindow.
Definition at line 167 of file qhaikuwindow.cpp.
References m_window.
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.
