About the callback¶

Its prototype is fun [ObjGtkWidget u0 S] u1
The supplemental argument is the selected path. This path is relative to the partition.
It needn't to destroy this widget. It should be it automatically.

If the user clicks on the Cancel button or the close icon, the callback won't be called.
If no path is selected or the path is incorect, the supplemental argument is nil.
