Description

OwnerDraw is a Boolean property which indicates if the menu items are drawn using the OnDrawItem event handler. The default value for the property is False.

OwnerDraw is used when the widgetset class renders the menu. If OwnerDraw is False, the default drawing routines for the platform are used to draw the menu control. Otherwise, the OnMeasureItem and OnDrawItem event handlers are signalled for the purpose.

Remark: OwnerDraw, OnDrawItem, and OnMeasureItem are not supported on the macOS Carbon, GTK2, QT4, QT5, and QT6 widgetsets.
