Hello!

I'm missing the events OnMouseEnter and OnMouseLeave for the TColorLineTool.

When I right click on a TColorLineTool I want my popupmenu to activate the feature "Delete ColourLine".
Is there some other way to do this without the above events?

Regards, Mikael

Hello,

You could use Chart's OnMouseDown event in combination with the tool Clicked function to check if the TColorLine has been clicked. For example:

Code: Select all

procedure TForm1.Chart1MouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
var i: Integer;
begin
  for i:=0 to Chart1.Tools.Count-1 do
    if (Chart1.Tools[i] is TColorLineTool) then
      if (Chart1.Tools[i] as TColorLineTool).Clicked(X,Y) then
      begin
        Chart1.Tools.Remove(Chart1.Tools[i]);
        Chart1.Repaint;
      end;
end;
