I don't see behaviour mentioned in removed comment. By default expand buttons
are hidden, that's controlled by NSTCS_HASEXPANDOS style. Once visible single click
on the button expands/collapses, and double click on the label does the same.
Additional flag NSTCS_SINGLECLICKEXPAND controls label clicks, enabling single click
there. That maps directly to TreeView styles, requiring no fixups in notification
handlers.
