Hi,

Is this another LCL bug or not?

See the attached image. The selected node's normal image (not the state image) is not painted for the selected node. I'm using the latest Lazarus 0.9.30.x compiled with FPC 2.5.1 using GTK2 widgetset.

In the attached image, the selected node (Test Suite 1 -> Test1) should have had a green square node image. As soon as I click on any other node in the treeview, that new selected node's image disappears, and the previously selected node's image appears.

Yes, that's why I'm using state images all the time , don't know is this bug or not, maybe someone else with more knowledge on Delphi TTreeView knows more about it.

The TreeNode has ImageIndex and SelectedIndex. First image is displayed when node is not selected, second is displayed when image is selected. If you want the image to be always displayed set both indexes to the same value.

In that case, it clearly seems like a bug. Because with this behaviour (and your suggestion), I can't share TTreeview code between LCL and VCL, which uses both image list properties of TTreeview.

Also, in Delphi the state images appear on the far left, not on the far right. Here is a screenshot of TTreeview under Delphi.

Ah thanks for the explanation. Is that how Delphi works too?

Yes.
