(Resolved) Treeview with selection gauges

[jimmymou]

Hello !

I have a Treeview that populates a listview (exactly like a stupid file explorer). In the listview, the user can select elements (checkboxes are activated for each element). So I can select several elements in several directories.

How can I adapt the Treeview to create a sort of representation of the selections already made (selections can be multiple), a sort of easy way of seeing wich directories contain selected elements.

In fact some backup programs perform this same way with the Directories Treeview : there are gauges (small square), empty=no selection, blue = some selections, red =everything selected in that directory. Perhaps with the picture attribute of a node ?

Any ideas ???

Thanks in advance guys...
