TImageEnView.OnLayerSelectionChange
Declaration
property OnLayerSelectionChange: TNotifyEvent;
Description
Occurs whenever a layer is selected or deselected. Unlike
OnLayerNotifyEx, this fires even with programmatic changes to selection.
A selected text layer:
Four selected layers:
procedure TfrmMain.IEView1LayerSelectionChange(Sender: TObject);
begin
// Enable the cut and copy buttons if layer cut/copy is possible
btnCut.Enabled := IEView1.Proc.CanCutFromClipboard( iecpLayer );
btnCopy.Enabled := IEView1.Proc.CanCopyFromClipboard( iecpLayer );
end;
