I'm using D7, TTreeView, TImageList and Bitmaps(BMP 16x16), Default parameters for the Treeview and ImageList except the following: Treeview1.Images := ImageList; TreeView1.StateImage := nil; I have a lot of items loaded dynamically onto the treeview and I set their Imageindex to the relevant ImageIndex in the ImageList. If a user deletes an item, the image should have a little cross over the normal image. Creating duplicate images with a cross over is not my style. So I am trying to use a mask that I put over the image when it is deleted, so that I can show a history trail. After a day of trying with no sucess. I have come to the conclusion that I am either stupid, or missing something critical or both. Can someone please enlighten me... D PS Bitmaps can be changes to anything else that can be dumped into a .res file.

Anyway: an imagelist allows you to define up to four of its images as overlay images. You do that using the imagelists Overlay method. The overlays get an independent index from 0 to 3. This you can then use for the OverlayIndex property of a TTreenode. So, put an image with your x overlay into the imagelist, call the Overlay method to define it as overlay #0, then set your nodes Overlayindex to 0. -- Peter Below (TeamB) Use the newsgroup archives : http://www.mers.com/searchsite.html http://www.tamaracka.com/search.htm http://groups.google.com http://www.prolix.be Back to top Derrick Erwee Guest Posted: Mon Mar 14, 2005 2:20 pm    Post subject: Re: Newbie: TreeView ImageList Thanks, sorry for posting in the wrong section "Peter Below (TeamB)" <100113.1101 (AT) compuXXserve (DOT) com> wrote Quote: In article <422fde3b (AT) newsgroups (DOT) borland.com>, Derrick Erwee wrote: I'm using D7, TTreeView, TImageList and Bitmaps(BMP 16x16), Default parameters for the Treeview and ImageList except the following: Treeview1.Images := ImageList; TreeView1.StateImage := nil; I have a lot of items loaded dynamically onto the treeview and I set their Imageindex to the relevant ImageIndex in the ImageList.
