setParent()

void QWaylandWindow::setParent ( const QPlatformWindow *  parent )

virtual

This function is called to enable native child widgets in QPA.

It is common not to support this feature in Window systems, but can be faked. When this function is called all geometry of this platform window will be relative to the parent.

Reimplemented from QPlatformWindow.

    qWarning("Sub window is not supported");
}

setVisible()

void QWaylandWindow::setVisible ( bool  visible )

virtual

Reimplemented in subclasses to show the surface if visible is true, and hide it if visible is false.

Reimplemented from QPlatformWindow.

Definition at line 96 of file qwaylandwindow.cpp.

{
    if (!mSurface && visible) {
        mSurface = mDisplay->createSurface(this);
