Description
Occurs on owner-draw menu items to determine menu item size before the menu is drawn.
Write an OnMeasureItem event handler to indicate the size of owner-draw menu items. If the menu item is using a bitmap image, the event handler can use the Bitmap property or the ImageIndex property to access the bitmap to determine its size.
Note: OnMeasureItem will only occur if the parent menu's OwnerDraw property is true or the parent menu's Images property has been set.
