Hi,

The TTreeview seems to fire a lot of events which doesn't seem right. Attached are two images showing what I did.

treeview_form_gets_focus.png
Here the form containing the treeview simply got focus. Note all the events that fired - as shown in the debug server.

treeview_select_node_changed.png
Here I simply selected a different tree node. Again, note all the events that fired due to that action - all events inside the red rectangle.

Is this normal?

As mentioned below, OnGetImageIndex is probably triggered from paint method, it triggers per item (because each item can have different image or no image at all).

treeview_select_node_changed.png Here I simply selected a different tree node. Again, note all the events that fired due to that action - all events inside the red rectangle.

This one seem ok. Selection is changed, OnGetImageIndex is probably called from paint method.

Is this normal?

Looks good

Yes.
The selection triggers a paint, which paints every visible node, which triggers one OnGetImageIndex for each node.

OK, I can probably take that as an answer, because the unfocused Window (or Treeview) paints the selected node differently. But why the odd number of events? The treeview only has 6 nodes, but there was 10 events fired.
