property OnGetImageIndex:;Description
OnGetImageIndex is a
TTabGetImageEvent property with the
event handler signalled to get the ordinal position for the image displayed
for the specified tab. It is signalled (when assigned) from the GetImageIndex
method, and allows the application to override the value assigned to the
ImageIndex property in a page object (TCustomPage).
The Sender argument is the object (TCustomTabControl) for the event
notification.
TabIndex contains the ordinal position for a tab/page which is
visible on the tabbed control.
ImageIndex is a variable argument used to return the position in
Images for the bitmap displayed on the specified tab. Return -1 in the
argument value if an image is not available in Images or not needed for the
tab.
