In the following function, I want to capture the ielResized event after the user changed the size of the line layer with the mouse.
void __fastcall TImageForm::ImgEnMainLayerNotifyEx(TObject *Sender, int layer, TIELayerEvent event){
if (event == ielResized) {
// update info

}
}
But I can't receive the ielResized event, after ielMovedPoint I only got ielEditedPoints.So how to capture the ielResized event?

Hi

ielResized only occurs for MouseInteractLayers of mlResizeLayers.
For mlEditLayerPoints, completion of the action triggers ielEditedPoints.

Hi

Moved point is an ongoing change. ielEditedPoints is when the editing is completed.

If you want to force completion of the current editing, you would need to enact it.

var
  idx: Integer;
  lyrCreateTool: TIELayerCreateInteraction;
begin
  idx := ImageEnView1.UserInteractions.FindInstanceOf(TIELayerCreateInteraction);
  lyrCreateTool := ImageEnView1.UserInteractions[ idx ] as TIELayerCreateInteraction;
  lyrCreateTool.Enact();
end;
