public property TCustomImageList.OnChange : TNotifyEvent |
OnChange is a TNotifyEvent property with the event handler signalled when one or more of the image(s) in the list have been changed. It is signalled (when assigned) from the Change method, and occurs when methods which modify the images in the list are called. This includes methods like: Add, Clear, Delete, Move, ReadData, and ReadAdvData. It is called from the EndUpdate method when the update count for the control reaches 1. It is also called when the value in the BkColor property has been changed and the images in the list are updated.
