◆ renderWindow() [1/2]

QWindow * QQuickWidgetRenderControl::renderWindow ( QPoint * offset )

overridevirtual

Reimplemented in subclasses to return the real window this render control is rendering into.

If offset is non-null, it is set to the offset of the control inside the window.

Note: While not mandatory, reimplementing this function becomes essential for supporting multiple screens with different device pixel ratios and properly positioning popup windows opened from QML. Therefore providing it in subclasses is highly recommended.

Reimplemented from QQuickRenderControl.
