Move drag_pointer() and related definitions from floating.c to new file
drag_pointer.c since it's applicable not only to floating windows but
also to resizing of tiled windows.
Some apps including XTerm start with a WM_CLIENT_LEADER property
containing their own window ID. Before this commit, i3 tried to center
such windows onto itself and did it wrong since
`leader->rect == {0,0,0,0}` at this moment.
The first affected commit is 128122e766,
however, before it such windows already was misplaced, but got sanitized
afterward [1].

Fixes#3785 -- the issue where the Travis build failed because of gcc's
-Werror=address-of-packed-member.
Adds an equality function to avoid relying on memcmp().

- ICCCM says: > If a base size is not provided, the minimum size is to
be used in its place and vice versa.
i3 didn't obey the "vice versa" part. Min size and base size are both
saved without replacements in window_update_normal_hints,
floating_check_size makes the needed replacements if either was not
provided.
- Aspect ratio is now saved correctly in manage_window because
window_update_normal_hints is called.
- i3 didn't save the aspect ratio if the window conformed the given
aspect ratio range when handle_normal_hints was called. If the window
was resized to a size outside of the given bounds, i3 didn't correct it.
- Aspect ratio now affects only tiling windows, like the rest of the
normal size hints
- The aspect ratio calculation is now done without a loop
A real life example of how these changes affect the workflow:
An mpv window, when playing a video, sets its min == max aspect ratio
during mapping. i3 ignored these hints. When resized, the window's
aspect ratio was not preserved. With this commit, resizing floating mpv
windows will always preserve the aspect ratio.
These are the changes that clang-format 6.0.1 makes to the codebase that
clang-format-3.8 doesn't change back.
Useful for those that use a more recent version of clang-format in their
local machines.
A race condition is possible. For example, if we first receive a
XCB_MOTION_NOTIFY event and then, while drain_drag_events is still
running, a XCB_BUTTON_RELEASE event the first event is never handled
because we return.
This fixes the flakiness of the tests in #3085.
Right now tree_render() is called twice on DRAG_REVERT since
floating_reposition calls it.
Also, on DRAG_REVERT the scratchpad state shouldn't change since the
user canceled the action.
This commit makes multiple changes in tree_close_internal. I didn't
split them because they are not completely independent.
- Remove force_set_focus parameter
This parameter was always set to `false` throughout the code base except
for one case where it was set to `(con == focused)`, when killing a
floating con's parent (the one with type CT_FLOATING_CON). But this case
is not needed anymore since the special handling of CT_FLOATING_CONs in
con_next_focused was removed in #2941.
- Assume that con_next_focused does not returned a container of type
CT_DOCKAREA. This is reasonable since con_next_focused uses the
focus_head stack and has special handling of CT_DOCKAREA containers.
- Remove is_mapped
This variable was only used in the if block towards the end of
tree_close_internal. Ignoring the, now removed, dockarea code and the
use of force_set_focus this block performed only one useful action:
focus the `next` container when `con == focused`. `con == focused` was a
necessary and sufficient condition for the con_activate call:
if `con != focused` we could reach the inner if blocks because of the
other conditions but would never focus another container. If `con ==
focused` then all other conditions would be irrelevant.
- Remove special handling of floating containers
Since the `next` focused container is calculated through the parent for
floating containers, I moved this code to con_next_focused.
Also, because of the removal of force_set_focus, it appears that we can
call con_on_remove_child for floating containers as well.
This significantly reduces the number of ELOGs while dragging floating
containers. The behaviour is improved since floating containers in the
edge of the screen will still get reassigned to their closest workspace.
For example, consider this setup:
fake-outputs 500x500+0+0,500x500+500+0
Now, open a window in the right output and run:
i3-msg floating enable, move position 0 px 450 px
The window is on the bottom edge of the left workspace but if you run:
i3-msg focus mode_toggle
focus will go to the right workspace since floating_maybe_reassign_ws
didn't change the assigned workspace of the floating container.
This allows the floating container's top left corner to be mapped
outside any output as long as they are contained partially by one. This,
for example, will allow:
mpv --geometry +1+1 video.mp4
For windows mapped to (0, 0) see comment in floating.c:270-273:
/* Some clients (like GIMP’s color picker window) get mapped
* to (0, 0), so we push them to a reasonable position
* (centered over their leader) */
The floating_reassign_ws call is removed since we try to place the new
floating container in the current output:
/* Sanity check: Are the coordinates on the appropriate output? If not, we
* need to change them */
Fixes#1341
With this change i3 will correctly switch to the focused workspace.
This fixes bug with moving floating windows with 'move <direction>' or by dragging like _NET_CURRENT_DESKTOP not getting updated or 'workspace back_and_forth' not working.
Fixes#2921.
Previously, we used ev_check watchers, which are executed at the beginning of an
event loop iteration.
This was problematic if one of the handlers happened to fill the XCB event
queue, e.g. by reading a reply from X11 and an event happened in the meantime.
In that situation, we would hand control to the event loop, entirely ignoring
the pending event. This would manifest itself as a 1-minute hang,
reproducible (sometimes) in the i3 testsuite.
issue #2790 describes an instance of this issue in i3bar, and we fixed that by
changing the watcher priority to run last. Handling events in xcb_prepare_cb has
the same effect, as ev_prepare watchers are run just before the event loop goes
to sleep.
This fixes a crash that occurs when disabling floating for a container
while it is being moved or resized.
@Deiz describes the problem:
> It occurs because the command that disables floating runs before the
event loop. So, the window is tiled, its floating parent is destroyed,
but then a key event is handled which causes the position/size of the
now-destroyed parent to be modified.
Fixes#1627
This commit introduces proper support for the minimum size on floating
windows by ensuring that it is respected during mapping, later changes as
well as resizes.
Furthermore, this commit fixes minor issues with how the hints are handled
during calculations.
fixes#2436
Fix the issue #2421 (https://github.com/i3/i3/issues/2421).
floating_enable() invokes tree_close_internal() to free con->parent.
After con->parent is freed in tree_close_internal() but before con->parent is reassigned by the caller, con->parent may be dereferenced and causes i3 crash.
The backtrace below is an example.
The already-freed pointer is dereferenced again through the pointer "focused" in x_push_changes().
Reassign con->parent before calling tree_close_internal() to fix this use-after-free bug.

Including config.h is necessary to get e.g. the _GNU_SOURCE define and
any other definitions that autoconf declares. Hence, config.h needs to
be included as the first header in each file.
This is done either via:
1. Including "common.h" (i3bar)
2. Including "libi3.h"
3. Including "all.h" (i3)
4. Including <config.h> directly
Also remove now-unused I3__FILE__, add copyright/license statement
where missing and switch include/all.h to #pragma once.
This code has been neutralized for many years now and served no purpose
other than cluttering up the code. We obviously don't need it and it's
out of date anyway.
If there's ever any reason to restore (parts of) it, we have git for
that. But we don't need to keep commented out code around.
This patch introduces a proprietary atom I3_FLOATING_WINDOW which will be
set and maintained for floating windows and removed on tiling containers.
This allows users to select on this atom, e.g., in their compositor
configuration or in utility scripts (without using the IPC).
fixes#2223
This is essentially a revert of daf00a9 which introduced a mechanism
to float workspace containers by wrapping all children into a new
container and floating it.
This caused a bug and there's no good reason (anymore) to allow doing
this in the first place as we don't support floating nested containers.
