Description
Occurs when a tab is about to display its associated image.
Write an OnGetImageIndex event handler to specify the ImageIndex for a given TabIndex.
On entry to the event handler, the ImageIndex parameter is the same as the TabIndex parameter, where TabIndex is the index of the tab which is about to display its image. Change the ImageIndex parameter to specify the index into the Images property that specifies the image that should be painted.
OnGetImageIndex is an event handler of type Vcl.ComCtrls.TTabGetImageEvent.
