TTreeView selecting top nodes?

[cyprus106]

Alright, so I've got this tree view that is always expanded. Can't collapse. And it's kind of in the format of:

+Category1
-Subitem1
-Subitem2
-Subitem3
+Category2
-Subitem1
-Subitem2
-Subitem3

For some reason, maybe just stupidity, I can't for my life seem to be able to catch the selected category when a user double clicks it. I tried selected but instead of showing me the selected category, it lists the selected subitems. The categories can be dynamically added and removed by the user so I can't hardcode in anything. I'm not exactly sure what the problem is--you'd think i'd be simple enough but I just can't get that 'Selected' to work.

Dear cyprus106,
I had a looong chat with my treeview in the beginning of using bcb5.

I got it working and let me just collect some ideas I have:

(MTV is mytreeview, MTN mytreenode, ok?)

MTV->AutoExpand = false; // should let You collapse all

When I use any ttreenode, and want it selected after a doubleclick, then I wrote a MTV->OnChange Handler
where I change a pagecontrol and set the

TTreeNode *MTN = MTV->Selected;
MTN->Selected = true;

MTN can be Category or Subitem, no problem.
I have done the same for a rightclick handler, works fine, too.
And You said something about topnode:
MTV->TopItem = MTN; // should work, maybe You set the MTV->Selected->Selected = true; // afterwards

Maybe this helps?
otherwise I will try to post more code.

Best regards,
Michael
