2012-04-26Rename TouchEnsureSprite to TouchBuildSprite and event type checksChase Douglas1-2/+2
The function will be used for building a sprite for pointer emulation after an explicit device grab. This commit refactors the code so that TouchBuildSprite will function with any event type and moves the checks to the caller.

2012-03-30Xi: Fix TouchEnd to TouchUpdate change for one accepted grabChase Douglas1-1/+2
If there is only one listener of a touch, the listener is a grab, and is accepted before the touch has ended, the current code will not end the touch record when the touch does end. This change adds a listener state for when a touch is accepted but has not yet ended. We now keep the touch record alive in this state, but end it when the touch ends.

2012-03-27Introduce a consistent coding styleKeith Packard63-5376/+4934
This is strictly the application of the script 'x-indent-all.sh' from util/modular. Compared to the patch that Daniel posted in January, I've added a few indent flags: -bap -psl -T PrivatePtr -T pmWait -T _XFUNCPROTOBEGIN -T _XFUNCPROTOEND -T _X_EXPORT The typedefs were needed to make the output of sdksyms.sh match the previous output, otherwise, the code is formatted badly enough that sdksyms.sh generates incorrect output. The generated code was compared with the previous version and found to be essentially identical -- "assert" line numbers and BUILD_TIME were the only differences found. The comparison was done with this script: dir1=$1 dir2=$2 for dir in $dir1 $dir2; do (cd $dir && find . -name '*.o' | while read file; do dir=`dirname $file` base=`basename $file .o` dump=$dir/$base.dump objdump -d $file > $dump done) done find $dir1 -name '*.dump' | while read dump; do otherdump=`echo $dump | sed "s;$dir1;$dir2;"` diff -u $dump $otherdump done Signed-off-by: Keith Packard <keithp@keithp.com> Acked-by: Daniel Stone <daniel@fooishbar.org> Acked-by: Alan Coopersmith <alan.coopersmith@oracle.com> (cherry picked from commit 9838b7032ea9792bec21af424c53c07078636d21)

2012-02-08Implement touch early acceptChase Douglas1-0/+2
This doesn't really implement early accept as it should. Ideally, the server should send end events to all subsequent touch clients as soon as an early accept comes in. However, this implementation is still protocol compliant. We can always improve it later.

Does not include pointer emulation handling. Does include partial ownership handling but not the actual processing of ownership events. Note: this commit is a retroactive commit extracted from a series of ~50 commits and may thus appear a bit more complicated than what you'd write out from scratch. Pointer processing tree is roughly: - ProcessOtherEvents - ProcessTouchEvents - DeliverTouchEvents - DeliverTouchBeginEvent|DeliverTouchEndEvent|... - DeliverOneTouchEvent Also hooks up the event history playing to the right function now.

2011-12-21dix: add touch event history helper functionsPeter Hutterer1-0/+4
If touch client has not registered for ownership events and a grab above that client is rejected, the client needs to receive the complete event history. The history currently doesn't really do fancy overflow handling. We assume that the first TOUCH_HISTORY_SIZE events are the important ones and anything after that is dropped. If that is a problem, fix the client that takes > 100 event to decide whether to accept or reject. Events marked with TOUCH_CLIENT_ID or TOUCH_REPLAYING must not be stored in the history, they are events created by the DIX to comply with the protocol. Any such event should already be in the history anyway. A fixme in this patch: we don't have a function to actually deliver the event yet.

2011-12-19input: add a TouchClassRec to the devicesDaniel Stone2-0/+80
These structs will be used to store touch-related data, events and information. Drivers must call InitTouchClassDeviceStruct to set up a multi-touch capable device. Touchpoints for the DDX and the DIX are handled separately - touchpoints submitted by the driver/DDX will be stored in the DDXTouchPointInfoRec. Once the touchpoints are processed by the DIX, new TouchPointInfoRecs are created and stored. This process is already used for pointer events with the last.valuators field. Note that this patch does not actually add the generation of touch events, only the required structs. TouchListeners are (future) recipients of touch or emulated pointer events. Each listener is in a state, depending which event they have already received. The type of listener defines how the listener got to be one.
