      Port QPA away from Wayland · bebe8120
      Vlad Zahorodnii authored
      So far wayland was used by internal clients to submit raster buffers
      and position themselves on the screen. While we didn't have issues with
      submitting raster buffers, there were some problems with positioning
      task switchers. Mostly, because we had effectively two paths that may
      alter geometry.
      A better approach to deal with internal clients is to let our QPA use
      kwin core api directly. This way we can eliminate unnecessary roundtrips
      as well make geometry handling much easier and comprehensible.
      The last missing piece is shadows. Both Plasma::Dialog and Breeze widget
      style use platform-specific APIs to set and unset shadows. We need to
      add shadows API to KWindowSystem. Even though some internal clients lack
      drop-shadows at the moment, I don't consider it to be a blocker. We can
      add shadows back later on.

      Use nullptr everywhere · 62a7db70
      Vlad Zahorodnii authored
      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).
      Test Plan: Compiles.

      Switch to Q_ASSERT · 7a3722b4
      Vlad Zahorodnii authored
      Switch to Q_ASSERT in order to make code a bit more consistent. We have

      distributions like Ubuntu don't strip away assert(), let's hope that

      Use more traditional doxygen style · 684b4b63
      Vlad Zahorodnii authored
      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.

      Port window specific rules dialog to DBus · 0b28abeb
      Martin Flöser authored
      The dialog invoked through user actions menu takes the internal uuid as
      command line argument which allows to query the required information
      from KWin instead of using X11.
      This allows to enable the system for Wayland windows.
      In order to replace the usage of ClientMachine in the rules dialog the
      dbus interface is extended by a value whether the window is on the
      localhost. This is exposed through a virtual method on toplevel which is
      overridden in ShellClient and there always returning true.

      David Edmundson authored
      If updating a shadow means that there should be no shadow, shadow ends
      up deleting itself midway through the method.
      It's cleaner and safer to leave that to the caller.
      This new change matches the existing documentation for

      Introduce the concept of an internal window system independent id · 3ad9ac72
      Martin Flöser authored
      For supporting Wayland windows in the kwin_rules_dialog we need a way to
      pass a window id for Wayland windows to the dialog. This id needs to be
      sent to the dbus interface to query window information just like the
      interactive query. For Wayland windows we don't really have a window id
      and it would require to also pass the windowing system to
      kwin_rules_dialog and back through the dbus interface.
      To not complicate things this change introduces a windowing system
      independent id based on UUID. This could in future also be used
      internally for areas where it's window id based and used in both
      windowing systems.

      Render GL Window decorations at the correct scale · fc887ab9
      David Edmundson authored
      Under wayland we support high DPI putting by putting a separation
      between the logical co-ordinate system and the resolution of rendered
      When a window is on a high DPI screen, we should render at the higher
      Like the window scaling this handles any combination of a 2x scaled
      decoration being rendered on a 1x screen or vice versa.
      This patch is a bit different from the other scaling stuff. We have to
      generate the quads *before* we have an updated texture with the new
      scale. This means the scale isn't attached to the buffer like elsewhere.
      That's why I added a property in TopLevel so there's still one canonical
      source and things can't get out of sync.

      Test Plan:
      Crystal clear breeze and oxygen decos on my @2x display

      Add support for resize only borders on Wayland · fb59b054
      Martin Flöser authored
      This change adds support for resizing outside the window decoration
      (e.g. setting borders to NoSide or None).
      To support this a new Toplevel::inputGeometry() -> QRect method is
      added which exposes the geometry adjusted by the margins provided by
      the decoration. This is checked in InputRedirection when finding a
      Toplevel at a given position. The logic for figuring out whether the
      event should go to the decoration or the window already handled the
      situation correctly, so no further changes are needed.

      DiscardWindowPixmap when Surface size changes · be79d1ae

      So far this connect was only in ShellClient, but it's needed for all
      Toplevels. Also when a XWayland window has it's surface size changed,
      the pixmap needs to be discarded. Otherwise KWin might hit an assert

      the texture had previously.

      Remove the unredirect fullscreen windows functionality · 996ee34e
      Martin Flöser authored
      Rational: unredirect fullscreen windows is a weird beast. It's intended
      to make fullscreen windows "faster" by not compositing that screen. But
      that doesn't really work as KWin jumps out of that condition pretty
      quickly. E.g. whenever a tooltip window is shown. KWin itself has a
      better functionality by supporting to block compositing completely.
      The complete code was full of hacks around it to try to ensure that
      things don't break.
      Overall unredirect fullscreen has always been the odd one. We had it
      because a compositor needs to have it, but it never got truly integrated.
      E.g. effects don't interact with it properly so that some things randomly
      work, others don't. Will it trigger the screenedge, probably yes, but
      will it show the highlight: properly no.
      By removing the functionality we finally acknowledge that this mode is
      not maintained and has not been maintained for years and that we do not
      intend to support it better in future. Over the years we tried to make
      it more and more hidden: it's disabled for Intel GPUs, because it used
      to crash KWin. It's marked as an "expert" option, etc.
      It's clearly something we tried to hide from the user that it exists.
      For Wayland the whole unredirect infrastructure doesn't make sense
      either. There is no such thing as "unredirecting". We might make use
      of passing buffers directly to the underlying stack, but that will be
      done automatically when we know it can be done, not by some magic is
      this a window of specific size.
      Test Plan:
      Compiles, cannot really test as I am an Intel user who never
      had that working.

      Update Keyboard focus when the Surface of the active client changes · 7adf69de
      Martin Flöser authored
      For XWayland windows the window might be activated before the Wayland
      Surface is set for it. Thus the keyboard focus is not passed to the
      window. Only on the next activate after the window got created the
      window got keyboard focus.
      This change addresses this problem by emitting a signal from Toplevel
      when the surface changes. The KeyboardInput listens to this signal
      for the active client and updates keyboard focus again if the surface
      changes. Thus keyboard focus is properly passed to XWayland windows.
      Test Plan:
      Test case which creates an X11 window is adjusted to verify
      the condition.

      Make Toplevel::window() no longer virtual and introduce ::windowId() · 24bdfc63
      Martin Flöser authored
      Toplevel::window() is the actual X11 window. This makes it difficult
      to use as the generic identifier for both X11 and Wayland. The Wayland
      ShellClient already had a windowId() which is now added to Toplevel as
      a virtual method. On X11 (Toplevel default) it returns the window().
      The method window() now returns XCB_WINDOW_NONE for classes without
      the Toplevel::m_client, such as ShellClient. Thus it allows to properly
      check whether we are on Wayland or X11.
      The code is adjusted to use windowId where a generic id is needed and
      to properly check whether the window is valid before using it where
      a window() is used.
      This also fixes at least one additional unknown issue in
      where the windowId of a Wayland client was passed to X11.

      Fix repaints area on Wayland damage · 34951b3b
      Martin Flöser authored
      The damage event of the Surface does not consider the offset through
      the server side decoration. Due to that we need to have a different
      repaint and damage area. As Toplevel::addDamage(QRegion) is only used
      in the Wayland case the repaint adjustment is removed from the generic
      implementation and moved into the specific implementations. While it
      wouldn't hurt to have the repaint adjustment in Toplevel, it would
      trigger a repaint of an unchanged area.
      For Client I'm not sure whether it's correct without considering the
      clientPos. My testing shows it's working, but that might also just be
      do to Xwayland using OpenGL buffers. Needs further testing.

      Remove saving and loading (and client matching by) WM_COMMAND. · 2eac7634
      Andreas Hartmetz authored
      This legacy session management scheme using the WM_COMMAND property
      seems to be called XSM. It is very, very legacy because it was
      superseded by XSMP in 1993(!).
      By inspecting ~/.config/session/kwin_[...] I could see that Firefox
      still sets WM_COMMAND, but nothing else in a regular session with
      some applications.
      As one of the last applications to switch to XSMP session management,
      I guess Firefox keeps doing that because it still needs to work on,
      say, Solaris, anyway, so why not set WM_COMMAND on Linux as well.
      The WM_COMMAND set by Firefox looks like "wmCommand8=firefox\s" in
      the kwin session file. It doesn't actually contain a session
      identifier. But then, Firefox only has one session per user anyway.
      This goes together with commit 5f0ca1305db4a925 in plasma-workspace /
      ksmserver to remove legacy session management support.
      I've talked about my plan to do this on IRC with Martin so hopefully
      it's okay to just do this now.

      channel a signal is emitted which implies that the hasAlpha property of
      Toplevel is no longer constant.
