Basically just copied from randr properties, with minor changes only.
Each device supports arbitrary properties that can be modified by clients.
Modifications to the properties are passed to the driver (if applicable) and
can then affect the configuration of the device.
Note that device properties are limited to a specific device. A property set
on a slave device does not migrate to the master.
When the opcode squash happened in the protocol, the processing vector got out
of sync for a few requests. As a result, client and server would interpret
requests differently, leading to a couple of BadLength problems.
Remember the version the client sent to us, so we can adjust our replies
accordingly. This requires the client to use the {major|minor}Version fields
in the GetExtensionVersion request. However, they were padding before, so we
must assume they are garbage if nbytes is non-zero. If nbytes is zero, the
client is probably a new client and we can handle it correctly.
If we have one global filter, one pointer may change the filter value and
affect another pointer.
Reproduceable effect:
blackbox and xterm, start dragging xterm then click anywhere with the other
pointer (attached to different masterd device!). The button release resets
the filter[Motion_Filter(button)] value, thus stopping dragging and no event
is sent to the client anymore.
Having the filters set per device gets around this.
Each time a different slave device sends through a master, an
DeviceClassesChangedEvent is enqueued. When this event is processed, all
classes of the matching master device are changed, and the event is sent to
the clients.
Next time the master is queried, it thus shows the evclasses of the last slave
device. The original classes are stored in the devPrivates.
TODO: if all slave devices are removed, the master's original classes need to
be restored.
The device state needs to be changed while processing the XI event. Core
events are always processed after XI, so by then the device is already set up
properly. However, we now rely on DeviceButtonMotionMask to be equal to
ButtonMotionMask. It already is, but stick a big fat warning in so nobody
attempts to change it.
This commit disables XKB for the VCK, thus essentially for all devices.
Temporarily anyway.
We need this to allow extensions to fill in extra data for an event before it
is sent to the client. This is probably to be used like
FillUpEventsFromWindow().
Add XGE handling in DeliverGrabbedEvent.
We can now grab something selecting XGE events, but the current code is a
bit messy and doesn't work too well yet.
Add RawDeviceEvent (pointers only for now).
This commit changes the event queue to use EventLists instead of xEvent
arrays. Only EQ is affected, event delivery still uses xEvent* (look for
comment in mieqProcessInputEvent).
RawDeviceEvents deliver driver information to the client, without clipping or
acceleration.
Calloc cursor struct to ensure devPrivates are zeroed out and don't
increase the refcnt for devices automatically when allocating a new
cursor. Use new DeviceIsPointerType() to detect if device is a pointer
_before_ device has been activated and can thus be identified and set
up grab functions accordingly. This way we can increase the refcnt
when we get a pointer grab.
dix: IsPointerDevice and IsKeyboardDevice, use same ways to identify type
of device as XI does for the XListInputDevices reply.
Autopair each non-pointer device with VCP when activating, pair with
real device after activation.
Don't return non-keyboard devices when calling GetPairedKeyboard or
PickKeyboard, otherwise we segfault for 'evdev brain'.
Adding PointerKeyboardPairingChanged event
Correct error values for XWarpDevicePointer
dix: Adding device argument to SendMappingNotify
Adding spriteOwner flag to devices
Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
change "foo.h" to <X11/foo.h> for core headers, e.g. X.h, Xpoll.h;
change "foo.h", "extensions/foo.h" and "X11/foo.h" to
<X11/extensions/foo.h> for extension headers, e.g. Xv.h;
change "foo.[ch]" to <X11/Xtrans/foo.[ch]> for Xtrans files.
