hi,
I think there might be some scope for improvement with the way the window
topbaris painted by nanowm.
In the redraw_ncarea function (actions.c line #20) it calls
active = (window->clientid == GrGetFocus());
nxPaintNCArea(window->wid, info.width, info.height, props.title,active,
props.props);
where depending on the status of the "active" parameter the nxPaintNCArea
decides the colour of the topbar.
I think that it should possibly do a depth first search on the window tree
starting at window->clientid and if any of the children is == to
GrGetFocus() then active should be kept true.
i.e.
[Window 1] has child [Window 2]
now focus is currently set to [Window2] (which needs it since it is a text
box or the like :-) )
[Window1] is listed with nanowm (because it is a child of GR_ROOT_WINDOW_ID)
But now active will not be true according to the old algorithm :-(
Since, this searching is a very heavyweight idea i suggest that the nanowm
keep a pointer to the currently active window and update it everytime. Maybe
you can work out some sort of an algorithm this way.
