For instance, I have a floating window that I created while I had `new_window none` enabled, and now that I've reverted to `new_window normal`, I'd like to have this window redrawn with a border without closing and reopening it. Is this possible? I tried toggling floating mode, but the border remained the same.Fri, 11 Oct 2013 16:15:17 +0000https://faq.i3wm.org/question/2682/modify-properties-of-an-existing-window-in-place/Answer by Michael for <p>Is there a way to modify the properties (such as the border style/size) of an existing window?</p> <p>For instance, I have a floating window that I created while I had <code>new_window none</code> enabled, and now that I've reverted to <code>new_window normal</code>, I'd like to have this window redrawn with a border without closing and reopening it.
