Summary

Occurs when the image has just changed.


Pascal

 published property OnChange: TNotifyEvent;


Description

OnChange is called immediately after the object changes. For example, TJclThreadPersistent’s descendant TJclBitmap32 uses the OnChange event to notify its parent that something was changed in a bitmap, and the screen image must be updated. Generation of OnChange events can be prevented by calling BeginUpdate.
