TreeView - GUICtrlSetOnEvent fails

[BugFix]

Hi,

i create an treeview and add items with _GUICtrlTreeView_Add() and _GUICtrlTreeView_AddChild() because set icon for items too. But GUICtrlSetOnEvent() has no effect. I think because UDF returns handle instead ID.

So i've tested WM_NOTIFY. It works, but with an offset of one click.

I hope, someone knows an solution.

    GUICtrlSetOnEvent($aID_Sub[$i-1], 'click_TV')  ; does'nt work (because have no ID and handle instead ?)

Here is one workaround:

Another solution would be to catch $TVN_ITEMCHANGED

When you catch nm_click then selection isn't changed in your function, it's just before "selection change".

Thanks for your reply, i'll test it too.
