TImageEnView.OnImageChange
Declaration
property OnImageChange: TNotifyEvent;
Description
Occurs after the image is modified using
TImageEnProc (
Proc property) or
TImageEnIO (
IO property).
If you are using multiple
Layers, then layer changes will also trigger
OnImageChange.
Notes:
-
TImageEnProc calls
ImageChange after a modification which actuates
OnImageChange.
- The
OnImageChangeEx event is also available, which is the same except that it includes a parameter showing whether the change is due to the image or layers
Example
procedure TForm1.ImageEnView1ImageChange(Sender: TObject);
begin
// Update status of buttons
btnSave.Enabled := ImageEnView1.IEBitmap.Modified;
btnUndo.Enabled := ImageEnView1.Proc.CanUndo;
btnRedo.Enabled := ImageEnView1.Proc.CanRedo;
end;
