Vlad Zahorodnii 1fb9f6f13a Switch to SPDX license markers
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.

In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.

Nate Graham 87578bfc15 Allow corner-tiling by quickly combining edge tiling shortcuts
Currently the only way for a uuser to invoke corner-tiling is to
manually set shortcuts for them. This patch adds another option: invoke
the existing shortcuts for edge tiling in a combined manner in quick
succession.

For example, hitting Meta+Left and then Meta+Up within a one-second
period will tile the active window into the top left corner. In practice
you hold down the Meta key and then press Left then Up (or Up and then
Left), and I think it feels very natural. Linux Mint's window manager
has this feature and I always missed it when I left Mint for the KDE
world.

Autotests for existing tiling shortcuts are adjusted to not break, and
additional tests for the new tiling options are added.

Vlad Zahorodnii 31ea780d79 [wayland] Rework xdg-shell implementation
Summary:
This change splits the XdgShellClient class to better match existing
abstractions in the xdg-shell protocol and fix a few issues related to
sending configure events.

In the new client classes, configure events are handled differently.
Instead of blocking configure events, we try to send them as late as
possible. Delaying configure events will let us merge changeMaximize()
for X11 clients and Wayland clients and it also fixes the bug where
we don't send the final configure event when user has finished resizing
a window.

Given that configure events are not sent immediately, XdgSurfaceClient
keeps the last requested frame geometry and the last requested client
geometry.

This patch doesn't intend to fix all issues in kwin's implementation of
the xdg-shell protocol. For example, we still handle surface unmapping
very poorly.

Test Plan: Tests pass.

Nate Graham 85b9aea5b4 Position OSD a bit farther down
Summary:
A common user complains is that our OSDs--particularly the volume OSD--are too intrusive
and get in the way of the screen content. For example when adjusting the volume while
watching a full-screen video, the volume change OSD will typically appear right in the
middle of an actor's face.

D20569 was an attempt to use a horizontal OSD to alleviate this issue. It mostly worked,
but IMO it was still positioned too high up.

This patch moved the placement down a little bit to make the OSD appear even farther from
the center of the screen to make it less likely to

I tried not to move it down too far or else it would interfere with subtitles in videos.

Aleix Pol 6abd23ed02 Make it possible to have a separate cursor for the tablet
Summary:
As is KWin only had 1 Cursor which was a singleton. This made it impossible for
us to properly implement the tablet (as in drawing tablets) support and show where
we're drawing.
This patch makes it possible to have different Cursors in KWin, it makes all the
current code still follow the mouse but the tablet can still render a cursor.

Vlad Zahorodnii a75fb7f84e Refactor geometry constraints code
Summary:
Currently, there are a couple of issues with sizeForClientSize(). First
of all, we have a method called clientSizeToFrameSize() which does similar
thing except applying geometry constraints and checking window rules. The
other issue is that sizeForClientSize() is doing a bit too much, it checks
window rules, it applies a bunch of geometry constrains. Sometimes it
does not perform conversion between client sizes and frame sizes!

This change attempts to address those issues by replacing sizeForClientSize
with two similar methods and changing semantics of some methods of the
X11Client class.

The most significant difference between sizeForClientSize() and the new
methods is that neither constrainClientSize() nor constrainFrameSize()
check window rules. This is up to users of those methods. In many places,
we don't have to check window rules because we check isResizable(),
which returns false if the frame size is enforced by a window rule.

Vlad Zahorodnii 9d4a32596c Drop some custom list typedefs
Summary:
Qt has its own thing where a type might also have corresponding list
alias, e.g. QObject and QObjectList, QWidget and QWidgetList. I don't
know why Qt does that, maybe for some historical reasons, but what
matters is that we copy this pattern here in KWin. While this pattern
might be useful with some long list types, for example

    QList<QWeakPointer<TabBoxClient>> TabBoxClientList

in general, it causes more harm than good. For example, we've got two
new client types, do we need corresponding list typedefs for them? If
no, why do we have ClientList and so on?

Another problem with these typedefs is that you need to include utils.h
header in order to use them. A better way to handle such things is to
just forward declare a client class (if that's possible) and use it
directly with QList or QVector. This way translation units don't get
"bloated" with utils.h stuff for no apparent reason.

So, in order to make code more consistent and easier to follow, this
change drops some of our custom typedefs. Namely ConstClientList,
ClientList, DeletedList, UnmanagedList, ToplevelList, and GroupList.

Test Plan: Compiles.

Vlad Zahorodnii 7d4471eba6 Rename geometry property to frameGeometry
Summary:
In order to properly implement xdg_surface.set_window_geometry we need
two kinds of geometry - frame and buffer. The frame geometry specifies
visible bounds of the client on the screen, excluding client-side drop
shadows. The buffer geometry specifies rectangle on the screen that the
attached buffer or x11 pixmap occupies on the screen.

This change renames the geometry property to frameGeometry in order to
reflect the new meaning assigned to it as well to make it easier to
differentiate between frame geometry and buffer geometry in the future.

Vlad Zahorodnii ffcbe24e2b Rename Client to X11Client
Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.

With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.

Renaming of Client to X11Client was agreed upon during the last KWin
sprint.

Test Plan: Compiles, the test suite is still green.

Vlad Zahorodnii 62a7db7028 Use nullptr everywhere
Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.

This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).

So far we were following a bit unique and rare doxygen comment style:

    /**
     * Contents of the comment.
     **/

Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.

    /**
     * Contents of the comment.
     */

Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.

This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

David Edmundson efc62941ee [wayland] Place all toplevels before the first configure
Summary:
Currently popups get positioned once at the initial configure, to set
the correct size and again when they are mapped.

Toplevels are currently only positioned when they are mapped. This works
for all cases where the the toplevel defines its own size, but not if
the window should have an initial size set by the placement strategy or
window rules. Most notably the maximised placement strategy used on
plasma mobile.

Being out of sync and resizing later currently causes a positioning bug
when plasma mobile is used with XdgShell.

This patch repositions all top levels that don't have a position set
through the plasma interface.

Summary:
placeIn did not handle the case for a popup not having had the size

There was also a logic bug when sliding popups. We called the
confusingly named setX thinking it would be move the popup keeping the
width the same. In practice it moves the left edge keeping the right
position the same. This wasn't an issue as the size was
discarded.

Martin Flöser 792d840455 Honor struts when placing Wayland transients
Summary:
So far transients were placed anywhere on the screen. This behavior was
inspired from X11 where context menus were able to overlap any other
window and use the complete screen area. On X11 context menus and
similar windows are override redirect and thus above all windows managed
by KWin.

On Wayland, though, context menus and similar and windows just like any
other window and thus follow stacking constraints like the parent
window. A context menu is stacked just above it's parent and is
(normally) below any panels. This resulted in problems that context menu
are stacked behind the panel with unreachable options.

This change changes the placement for transients to use the
PlacementArea instead of a screen geometry. Thus the transient does not
render behind the panel. Only in case of a fullscreen the struts are
ignored.
