Some systems (e.g. openSuSE) don't install the xkbcommon header into
/usr/include/xkbcommon/xkbcommon.h (which is always in the include path),
but instead into a subdirectory, which is in the openSuSE case
/usr/include/pkg/libxkbcommon/xkbcommon/xkbcommon.h. This means that e.g.
kcm_kwinrules will not compile there since it includes input.h
REVIEW: 117069
Forward all key press events to the TabBox if it is currently grabbed and
connect the TabBox to the modifiers changed signal for checking if TabBox
should be ended.
Used by Cursor to properly emit the mouseChanged signal which for
historic reasons includes the keyboard modifiers.
Again some fiddling around with the autotests and kcmrules needed to
make it compile. This needs improvement!
A new GlobalShortcutsManager is introduced which is responsible for
holding the registered shortcuts and triggering the matching action.
The InputRedirection checks with the GlobalShortcutManager whether a key
press event triggers a global shortcut and stops processing the event in
that case.
At the moment the GlobalShortcutsManager only supports the very basics
for KWin internal usage. External applications can not yet make usage of
the global shortcut system inside KWin.
When moving/resizing a window we don't want the keyboard events being
passed to the Clients. Instead we want to do the normal processing.
Unfortunately moving the window through the keyboard relies on warping
the pointer which is not (yet) available on Wayland. This means that this
is not yet working, but ending through enter/escape etc. is working as
expected.
Major new functionality is xkbcommon support. InputRedirection holds an
instance to a small wrapper class which has the xkb context, keymap and
state. The keymap is initialied from the file descriptor we get from the
Wayland backend.
InputRedirection uses this to translate the keycodes into keysymbols and
to QString and to track the modifiers as provided by the
Qt::KeybordModifiers flags.
This provides us enough information for internal usage (e.g. pass through
effects if they have "grabbed" the keyboard).
If KWin doesn't filter out the key events, it passes them on to the
currently active Client respectively an unmanaged on top of the stack.
This needs still some improvement (not each unmanaged should get the
event). The Client/Unmnaged still uses xtest extension to send the key
events to the window. So keylogging is still possible.
InputRedirection keeps track of the Toplevel which is currently the one
which should get pointer events. This is determined by checking whether
there is an Unmanaged or a Client at the pointer position. At the moment
this is still slightly incorrect, e.g. pointer grabs are ignored,
unmanaged are not checked whether they are output only and input shapes
are not yet tracked.
The pointer events are delivered to the Toplevel as:
* enter
* leave
* move
* button press
* axis event
Nevertheless move events are still generated in InputRedirection through
xcb test for simplicity. They are still send to the root window, so all
windows get mouse move.
Button press and axis are generated only in the implementations of the
event handlers and delivered directly to the window, so other windows
won't see it.
InputRedirection forwards pointer events (currently motion, press and
release) through the EffectsHandlerImpl for the case that an effect has
intercepted pointer events.
If the KWin operation mode is not X11 only, the window for intercepting
the mouse events is no longer created.
So far this new class is not yet doing much. The WaylandBackend forwards
the received pointer events to this InputRedirection class. From there
signals are emitted to inform internal areas about the changes first.
The events are currently forwarded to X through the xtest extension. This
will be removed in future. Input will be forwarded directly to the
surface which wants it (no matter whether X11 or Wayland).
