First, if float is called with window which is on a hidden workspace,
then the window will remain on that hidden workspace.
Now the focus should change more as expected:
float w = (view current) . (shiftWin ws w)
where
current is the current screen/workspace
shiftWin ws w is: - view the workspace w is on
- set focus on w
- shift ws
- set focus back to window it was on that workspace
unless w was focused
shiftWin was add to StackSet.hs
Rename delete to delete' so we can clear floating status in delete,
thus removing one special handling.
At the moment delete' is only used in shift, but is useful for temporarily
removing a window from the stack.
Say you have three windows A B C* on a workspace with * marking the focus.
If you close C or move it to another workspace, the resulting order will be B* A,
thus reordering the other windows, defying the comment of filter.
This change also removes the barely used 'size' field, and replaces
it with a tagMember predicate. The idea is to move towards the ability
to make the workspace tag be a String, which by default might be "1".."9",
but could also be customized to be something meaningful to the user.
This is a first attempting at a floating layer:
mod-button1: move window
mod-button2: swapMaster
mod-button3: resize window
mod-t: make floating window tiled again
Moving or resizing a window automatically makes it floating.
Known issues:
Hard to manage stacking order. You can promote a window to move it to the top,
(which you can do with mod-button2) but it should be easier than that.
Moving a window by dragging it to a different Xinerama screen does not move it
to that workspace.
Code is ugly.
The use of arrow keys for swapLeft/Right clash with firefox's back
button. Use the more intuitive mod-shift-jk for this. (It's a movement
operation, after all).
This clashes with IncMaster, so we use mod+comma and mod+period for
these (i.e. the keys mod < and mod > , to move windows to and from the
master area).
While we're here, replace the use of the terms 'left' and 'right' for
navigation, in comments and identifiers, with 'up' and 'down' instead.
Hence mod-j == focusDown. Far more intuitive for people (dons) who live
in fullscreen mode and have vim movement wired into their central
nervous system.
Principle of least VI surprise: movement down or up means using j and k.
This fixes a bug whereby deleting a window will first move focus to
that window before deleting it without moving focus back afterwards.
The fix generalises the remove inner function to delete a window from
the stack whether it's in focus or not. If the window is in focus,
behaviour remains as it was.
