Hello,

I have set LayerOptions to loAllowMultiSelect and loAutoSelectMask. This will automatically select Mask Layer when we select a normal layer. This is just fine.

But under some situations I would want to prevent ImageEn from selecting the Mask Layer. Like for example when a user presses Ctrl Key and clicks on a Layer the mask layer if associated with that layer should not get selected so when the user moves or resizes layer the mask should not move or resize with it.

Is it possible to do this?

If Yes then any ideas as to how to do this please.

TIA

Hi Yogi

Using the OnLayerNotify event you should be able to detect the selection of the mask layer and immediately deselect it:

Hello,

This code is not deselecting the mask layer.

if (layer > 0) and (layer < (ievMain.LayersCount - 1)) then
  begin
      if ievMain.Layers[layer + 1].IsMask then
      begin
        ievMain.Layers[layer + 1].Selectable := False;
      end;
  end;


I am saying this because when I move or resize an Image the mask is also getting resized!

TIA

Hi Yogi

The "Selectable" property is ignored if you have enabled loAutoSelectMask.

You are better to disable loAutoSelectMask and automatically select the layer mask yourself when the user clicks a layer.
