Before this fix, when using layoutHintsToCenter together with
MultiColumns, in certain situations XMonad would render the border of
the focused window below a border of unfocused windows. This looks odd
and is here fixed by changing MultiColumns to always place the focused
window in front (even though they should not really overlap) and making
LayoutHints preserve the order returned from the underlying layout,
except for the focused window that is placed on top.
This is a good idea since layoutHintsToCenter requires the focused
window to be on top for good rendering, even if that is not really
required when the underlying layout is used on its own. This way
layoutHintsToCenter requires less of the layout that is modified and
MultiColumns is more compatible with future layout modifiers that are
not so considerate.
Despite myLayouts currently being more popular in examples, make
them all myLayout as in man/xmonad.hs to avoid mixing them in the
same module as was done a few places, leading to confusion for some users.
This removes the emptyLayoutMod method from the LayoutModifier class, and
change the Stack parameter to redoLayout to a Maybe Stack one. It also changes
all affected code. This should should be a refactoring without any change in
program behaviour.
This patch includes several changes, which are strictly related and
cannot be recorded separately:
- remove Decoraion.isDecoartion and introduce Decoration.isInStack
(with the related change to LayoutHints)
- in Decoration introduce useful utilities: isVisible, isInvisible,
isWithin and lookFor'
- MouseResize: - invisible inputOnly windows will not be created;
- fix a bug in the read instance which caused a failure
in the state deserialization.
