Hi David,

Is it possible to switch focus only between visible windows without pulling hidden ones into the foreground?

It'd be an easy extension to write, but imagine it would be specific to the TwoPane layout, since I don't see how this could be implemented using the actual property of "switch focus between visible" windows.

Currently the TwoPane layout is the only layout that has hidden windows and multiple visible windows, so it wouldn't be a too big problem if it was specific to that layout.

Combo can also have this effect, particularly when combining with TwoPane. And Square behaves the same way.

Instead it'd be "switch focus between the first two windows".

So xmonad doesn't know what windows are visible and which one are hidden?

It'd have to re-display them, I believe. I don't know, maybe there is a way to find out. If so, it'd require some trickiness. Such trickiness, however, wouldn't work with Combo+TwoPane+Tabbed, since Tabbed hides windows by moving them to the back of the stack (i.e. so they are behind the focussed window), rather than by actually making them not visible. -- David Roundy Department of Physics Oregon State University

Out of curiosity: why does it do this?

It does this so Combo will work in combination with Tabbed (which is my normal layout). Without this behavior, Combo would need to keep track of which window was last visible within each sub-layout, so as to create a proper stack with that window having the appropriate focus. This is more book-keeping than I care to bother with, so I just use SimpleStacking. What Combo really wants is recursive Stacks, but reimplementing all of Operations in Combo is also more effort than I want to bother with. i.e. what I wish for would be something like: data Stack a = Singleton a | Stack [Stack a] (Stack a) [Stack a] so that you could describe a hierarchy of ordered window groupings with a given group focussed at each level. But we don't have that, so I need to approximate it, one way or another. I chose what seems to me to be the easiest approach--which is partly historical, since SimpleStacking used to be the default, built-in stacking approach. -- David Roundy Department of Physics Oregon State University
