I'd like to suggest adding another option to the TreeCtrl to allow optional highlighting of focused node's control along with value.
This is useful in situation when one wants to use RichTextCtrl with support of links as a node of TreeCtrl.
That can be useful for TreeCtrl-based widgets like OptionTree, which doesn't let you highlight selected node, I believe.
That can be done by changing one line (line 983) in TreeCtrl::Paint from
w.DrawRect(x, y, vsz.cx + 2 * m.margin, msz.cy, bg);
to
w.DrawRect(x - m.GetCtrlSize().cx, y, m.GetCtrlSize().cx + vsz.cx + 2 * m.margin, msz.cy, bg);
and adding of an appropriate flag and a set-method.
Regards,

Actually, a few more lines of code should be added ...
} else if(x - m.GetCtrlSize().cx < sz.cx) {
const Display *d = GetStyle(i, fg, bg, st);
w.DrawRect(x - m.GetCtrlSize().cx, y, m.GetCtrlSize().cx + vsz.cx + 2 * m.margin, msz.cy, bg);
}
