I try to draw a measureline,
ImageEnView.MouseInteract := [ miClickCreateLineLayers, miEditLayerPoints, miMeasureLength];


and then, I want to switch to select mode in ImageEnViewLayerNotifyEx procedure:
if ImageEnView.Layers[layer].Kind = ielkLine then
      begin
               if event in [ielCreated] then
               begin
                  ImageEnView.MouseInteract := [  miMoveLayers, miResizeLayers ];
               end
      end


but, this way my line disappears. Why?

Can you not disable line creation in the ImageEnViewLayerNotifyEx event, e.g.

procedure TMainForm.ImageEnView1LayerNotifyEx(Sender: TObject; layer: Integer; event: TIELayerEvent);
begin
  if event = ielCreated then
    ImageEnView1.MouseInteract := [ miEditLayerPoints ];
end;

But I want to disable create new line layers, after finished draw.
So I want to remove miClickCreateLineLayers property.

Why not just use:

ImageEnView.MouseInteract := [ miClickCreateLineLayers, miEditLayerPoints ];


miMeasureLength is for measuring lengths in an image.


You might also want to try Line Layers demo.

measure line isn't a line layer?
I think it is because the debugger catches after the condition
if ImageEnView.Layers[layer].Kind = ielkLine then


but does not matter.
I just want to know how to draw a line and then switch to selection mode
and why my line layer disappears

Hi

Are you trying to convert a measure line into a line layer?
