setSceneRectMarker()

void setSceneRectMarker ( const QRectF &  rect )

noexcept

Setup the marker for a specific scene rect.

This is intended to mark a specific area in a scene, with a line starting from the top left of the view, so the user can easily locate the specified area, even if it is very small.

Parameters

rect	The rect to mark. Pass an empty rect to clear the marker.
