Summary

Occurs when the image has just changed.

Pascal

 public 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.
