As far as I remember, there is a bug relating to OverlayIndex. You can only use index 0 as overlay.<br />

With OverlayIndex = 0 it doesn't work either...<br />

Do you do it like this? <br />
<br />
You have to call TImageList.Overlay first. <br />
Example:<br />
&nbsp;<br />
ImageList1.Overlay(Image_I<wbr />ndex, Overlay_Index);<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;TreeView1.Items[Item_Index<wbr />].OverlayI<wbr />ndex := Overlay_Index;<br />
<br />
Zif.<br />

I'm having trouble with displaying overlay masks in a TreeView.<br />
<br />
I'm having a treeview with some items with associated icons in it. I'm trying to use an overlay mask for some of these items by setting the OverlayIndex of the TreeNode to e.g. 1. This doesn't work; the original icon is still displayed.<br />
<br />
Does anybody have any suggestions or solutions?? Do I forget something? Any help will be appreciated, especially a working example!<br />
<br />
Thanks!
