Detailed Description

Raster or OpenGL Window.

\list

Raster type: handleWmPaint() is implemented to to bitblt the image. The DC can be accessed via getDC/releaseDC, which has special handling when within a paint event (in that case, the DC obtained from BeginPaint() is returned).

Open GL: The first time QWindowsGLContext accesses the handle, it sets up the pixelformat on the DC which in turn sets it on the window (see flag PixelFormatInitialized). handleWmPaint() is empty (although required). \endlist

◆ setGeometry()

void QWindowsWindow::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.

bool QWindowsWindow::startSystemResize ( Qt::Edges edges )

overridevirtual

Reimplement this method to start a system resize operation if the system supports it and return true to indicate success.

The default implementation is empty and does nothing with edges.

Since: 5.15

Reimplemented from QPlatformWindow.

bool QWindowsWindow::windowEvent ( QEvent * event )

overridevirtual

Reimplement this method to be able to do any platform specific event handling.

All non-synthetic events for window() are passed to this function before being sent to QWindow::event().

Return true if the event should not be passed on to the QWindow.

Subclasses should always call the base class implementation.
