This patch makes it possible to move views between outputs using the
`move left|right|up|down` commands.
It behaves similar to i3 with one important difference. The focus will
always follow the view being moved, unlike i3 where the focus doesn't
always follow the view to a new output (I assume that's a bug in i3).
`vertical` and `horizontal` should be swapped.
If border_left and border_right were set to 0, the vertical borders
instead of the horizontal borders would be hidden.
i3 handles this command equally.
Replace `update_view_border()` with `update_container_border()`. The latter
should handle both the case where the container is a view or if the container
has children.
When titlebar is hidden, top border of the topmost view inside
tabbed/stacked container will not be drawn. This is changed in layout.c
On the other hand, top border should be drawn sometimes, for example
when titlebar is hidden on a view that is not the topmost inside
tabbed/stacked container. This is changed in border.c
This patch makes sure to clear the border buffer of fullscreen view so
the border doesn't get drawn behind a fullscreen view, which would be
visible if the view was transparent.
The borders are implemented as a surface/buffer attached to each view
which is sent to and rendered by wlc in the view_pre_render callback.
All the drawing logic is handled in sway/border.c and all the logic for
calculating the geometry of the border/view is handled in
`update_geometry` in sway/layout.c (same place as gaps are calculated).
It's possible to assign workspaces to certain outputs using the command:
workspace <name> output <output>
However, this did not work in some cases where the workspace was
assigned before the given output was made available to sway.
This patch fixes those cases.
This patch aims to correctly handle moving focus <left|right|up|down>
between outputs.
For instance, if moving from one output to a new output at the left of
the current one, it should focus the right-most view/container on the
new output, and the opposite if moving from right to left. This should
happen regardless of the previously stored focus of the new output.
This also handles moving to a new output above or below the current one.
If the width or height of a container can't be evenly distributed to its
children, then the layout algorithm still thought it got it right (due
to using decimals) which caused a gap of one or more pixels for some
window arrangements.
This is fixed by this patch by first rounding off the width and height
(so that decimals are never introduced) and then adjusting the last
view in a container to fill the remaining pixels (which now is counted
correctly due to the decimals being removed).
Also, due to the way gaps are implemented, an odd sized gap can never be
aligned properly, so just adjust to closest even number.
