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>

/**
|
|
* @file
|
|
* This file describes the model for sending core enter/leave events and
|
|
* focus in/out in the case of multiple pointers/keyboard foci.
|
|
*
|
|
* Since we can't send more than one Enter or Leave/Focus in or out event per
|
|
* window to a core client without confusing it, this is a rather complicated
|
|
* approach.
|
|
*
|
|
* For a full description of the enter/leave model from a window's
|
|
* perspective, see
|
|
* http://lists.freedesktop.org/archives/xorg/2008-August/037606.html
|
|
*
|
|
* For a full description of the focus in/out model from a window's
|
|
* perspective, see
|
|
* http://lists.freedesktop.org/archives/xorg/2008-December/041740.html
|
|
*
|
|
* Additional notes:
|
|
* - The core protocol spec says that "In a LeaveNotify event, if a child of the
|
|
* event window contains the initial position of the pointer, then the child
|
|
* component is set to that child. Otherwise, it is None. For an EnterNotify
|
|
* event, if a child of the event window contains the final pointer position,
|
|
* then the child component is set to that child. Otherwise, it is None."
|
|
*
|
|
* By inference, this means that only NotifyVirtual or NotifyNonlinearVirtual
|
|
* events may have a subwindow set to other than None.
|
|
*
|
|
* - NotifyPointer events may be sent if the focus changes from window A to
|
|
* B. The assumption used in this model is that NotifyPointer events are only
|
|
* sent for the pointer paired with the keyboard that is involved in the focus
|
|
* events. For example, if F(W) changes because of keyboard 2, then
|
|
* NotifyPointer events are only sent for pointer 2.
