Emmanuel Lepage Vallee 90b17bdc09 awful.rules: Add proper documentation to the extra client properties.
Until now there wasn't much documentation available about how to use
these properties. With the new work on `awful.spawn` that rely more and
more on `awful.rules` integration, it is worth fixing.

This commit add a new documentation section and a future commit will
aggregate them to generate an index.

Uli Schlachter 21b7b29630 xwindow_translate_for_gravity: Change instead of set argument
Previously, this function overwrote the value of its argument with the
result. After this change, the function merely changes the given
variable by the calculated argument.

Thus, the old behaviour is achieved by setting the variable to zero
before the call, which all callers already did. However, for most
callers this change means that a temporary variable can be removed and
instead xwindow_translate_for_gravity() will directly change the target
variable.

No change in behaviour intended.

Uli Schlachter 56e727e026 Fix a race with setting the focus
There are two ways in which the input focus can change: Lua can request
a change and the X11 server can inform us that the input focus changed
(because some application changed it).

In the first case, we still have to inform the X11 server about the
desired change, in the second case we must not to avoid races due to
X11's asynchronous nature.

However, there was a case where we screwed up: When a focus change is
still pending, meaning that Lua assigned the focus elsewhere, but we
have not yet sent this focus change to the X11 server, we could get an
event from the X11 server telling us that the focus changed. To make
sure that the pending focus change is not lost, we sent the focus change
out in this case (call to client_focus_refresh() in
event_handle_focusin()). After sending out this pending call, we updated
the internal state to record that whatever the X11 server just told us
had the focus. The intention was that our just sent-out focus change
will cause the X11 server to send a new event and our to-be-focused
client then has the focus.

However, if the pending focus change was for a client which only showed
up in this event loop iteration, the client was still banned. This means
that client_focus_refresh() would call client_unban() to be able to give
the focus to this client. However, since awesome (partly) allows to
"focus" currently banned clients, client_unban() recorded that there is
a pending focus change. This caused confusion later on.

In this specific bug, a main window opened a dialog, and when this
dialog was closed, a new dialog window was opened immediately. When the
first dialog was closed, Lua (the focus history) gave the input focus to
the main window. Now, a new dialog showed up and Lua focused it. Next,
we received the event from the X11 server telling us that the main
window was focused. Because there was still a pending focus change to
the new dialog window, event_handle_focusin() called
client_focus_refresh() to send out this focus change. This set
globalconf.focus.need_update to false and continued. However, because
the new dialog only just now appeared, it was still banned, meaning that
client_focus_refresh() had to call client_unban(). This set
globalconf.focus.need_update to true. Thus, when client_focus_refresh()
returned, globalconf.focus.need_update was incorrectly true. Next,
event_handle_focusin() recorded that the main window had the focus.
Thus, it now appeared as if there was a pending focus change for the
main window. Next, we got the event from the X11 server telling us that
the dialog is now focused, and because focus.need_update was set,
awesome now send out a focus change request for the main window.

Fix this race by unsetting globalconf.focus.need_update at the end of
client_focus_refresh() and not at the beginning, thus making sure that
client_unban() cannot set this flag again.

Uli Schlachter 297003126d Handle unsetting of .transient_for
When a window has a WM_TRANSIENT_FOR property that is later unset,
awesome would still keep c.transient_for pointing to the previous
"parent client". This commit fixes that.

First, property_update_wm_transient_for() is fixed so that it unsets
c->transient_for_window if the WM_TRANSIENT_FOR property is deleted.
Additionally, this then calls client_find_transient_for() to update the
c->transient_for pointer.

Secondly (and a bit unrelated), this changes client_find_transient_for()
so that it always sets c->transient_for. Previously, if updating this
property would introduce a cycle in the transient_for relation, it would
just leave c->transient_for with its old value. After this change, it
gets explicitly set to NULL instead.

Uli Schlachter 6c27f4295b client_manage(): Check that reparenting works (#2298)
When a new client appears, we reparent its window into a window of our
choice so that we can add decorations. However, windows can be difficult
making the reparenting fail. For example, some snapshots of GTK+ set a
parent-relative background, which means that its parent windows have to
have the same depth as the window itself. This makes reparenting fail if
transparency is used/supported.

Make the failure mode... different, by checking if reparenting
succeeded. If it failed, we print an error message and unmanage the
window immediately. This means that those GTK+ windows just do not
appear at all, instead of behaving weirdly.

This idea of this patch came from i3.

Uli Schlachter 681025dc50 Make fake screens permanent (#2201)
* Make fake screens permanent

Before this, screen_scan() made sure that awesome's information about
available screens conforms to what the X11 server reports. Since fake
screens are, well, fake, this meant that they were deleted.

This commit marks fake screen and handles them specially in
screen_scan() so that they are not deleted.

Note that I did not test this commit at all since I still haven't
figured out how to test RandR stuff without actually messing with
hardware.

Uli Schlachter 1acae2aa6c Make alpha work on window borders
Up to now, we always asked the X11 server for color allocation ("which
pixel value corresponds to (r,g,b)?", an AllocCollor request).

This commit adds direct support for TrueColor and DirectColor visuals.
In such a visual, the X11 server gives tells us where the red, green,
and blue color components are in a pixel value and we can then just
directly compute the pixel value.

Additionally, this commit adds code that assumes that in a depth=32
visual, the remaining values (after handling red, green, blue) is the
alpha channel for colors. Thus, this adds support for transparent client
borders.

This commit also touches code for the systray. However, the systray must
always use the X11 server's default visual and that one always(?) has
depth=24, i.e. does not support an alpha channel. Thus, the systray
background still cannot be transparent.

Also, in theory this commit should support visuals where some color
component does not have 8 bits, for example RGB565. However, this is
just theoretic and I have no idea how to actually test this (without
jumping through too many hoops).

two calls, no other calls to client_ignore_enterleave_events() is

Uli Schlachter f290ea8b12 Stop grabbing mouse buttons on frame windows (#1724)
I failed to see the obvious. Thanks to mlen from IRC to make
me look into i3's source code so that I can figure out the obvious.

First, what is the problem? We want to be informed about mouse clicks on
client windows, e.g. for client-to-focus. For this we have to grab mouse
buttons on the client window, since only a single client at a time can
ask for information about all mouse clicks (I think...) and that right
is reserved for the actual application and not the WM.

We also want to be informed about mouse clicks on the titlebar, so that
clicking there actually does something (and also e.g. click-to-focus).
Obviously, we can just grab mouse buttons on the titlebar as well.

However, this causes lots of problems. The X11 window containing the
titlebar is not just the size of the titlebar, but also includes all of
the actual client window. This means that clicking into the client also
activates our button grab on the titlebar. This, in turn, causes the
input focus to briefly shift to the window for the titlebar. This shift
of focus can be detected by clients and caused various issues.

This fix is so obvious that I missed it. We don't have to grab buttons
on the titlebar window. We can just use the "normal" event propagation
without grabs there, i.e. we just include the event masks for button
press and button release and get informed about all mouse events. In
fact, we already have this event mask in place, so the whole use of
grabs is redundant.

That's what this commit does. It also partially reverts commit
394ff06589 which is where this unnecessary grabbing was introduced.

Uli Schlachter 51e4a47938 Partly fix removal of systray from a wibox
This commit changes the systray widget, wibox.drawable and the C code to
fix the following bug: When the systray widget is removed from a
drawable without being moved somewhere else, the systray stayed visible.
This was because the systray is not drawn by awesome, but only placed.
When the widget is no longer "drawn", it stays wherever it was placed
last.

This change works by detecting the situation when the systray is
removed. Then, the C code is specifically told to remove the systray
window from the drawable.

Note that this is only a partial fix. This change works correctly when
the widget is removed completely, because it is no longer placed by its
parent widget. However, for example, when you do
wibox.widget.systray().visible = false, the effect is just that the
systray widget gets size 0x0. This is not really visible, but as far as
this change is concerned, the widget is still part of the drawable.
