From 2039c6ea43244339659323d05d96c14e41996c20 Mon Sep 17 00:00:00 2001 From: Peter Hutterer Date: Mon, 7 Jul 2008 22:10:17 +0930 Subject: [PATCH] Xi: add support for input device properties. 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. --- Xi/Makefile.am | 6 +- Xi/extinit.c | 17 +- Xi/xiproperty.c | 755 +++++++++++++++++++++++++++++++++++++++++++++ Xi/xiproperty.h | 43 +++ dix/devices.c | 9 + include/exevents.h | 47 ++- include/inputstr.h | 41 ++- 7 files changed, 912 insertions(+), 6 deletions(-) create mode 100644 Xi/xiproperty.c create mode 100644 Xi/xiproperty.h diff --git a/Xi/Makefile.am b/Xi/Makefile.am index 2af1940eb..768f996cc 100644 --- a/Xi/Makefile.am +++ b/Xi/Makefile.am @@ -94,7 +94,9 @@ libXi_la_SOURCES = \ ungrdevk.h \ warpdevp.c \ warpdevp.h \ - xiselev.c \ - xiselev.h + xiproperty.c \ + xiproperty.h \ + xiselev.c \ + xiselev.h EXTRA_DIST = stubs.c diff --git a/Xi/extinit.c b/Xi/extinit.c index 613472ab6..7460d71ee 100644 --- a/Xi/extinit.c +++ b/Xi/extinit.c @@ -122,6 +122,7 @@ SOFTWARE. #include "ungrdevk.h" #include "warpdevp.h" #include "xiselev.h" +#include "xiproperty.c" static Mask lastExtEventMask = 1; @@ -217,7 +218,13 @@ static int (*ProcIVector[])(ClientPtr) = { ProcXSetClientPointer, /* 42 */ ProcXGetClientPointer, /* 43 */ ProcXiSelectEvent, /* 44 */ - ProcXExtendedGrabDevice /* 45 */ + ProcXExtendedGrabDevice, /* 45 */ + ProcXListDeviceProperties, /* 46 */ + ProcXQueryDeviceProperty, /* 47 */ + ProcXConfigureDeviceProperty, /* 48 */ + ProcXChangeDeviceProperty, /* 49 */ + ProcXDeleteDeviceProperty, /* 50 */ + ProcXGetDeviceProperty /* 51 */ }; /* For swapped clients */ @@ -267,7 +274,13 @@ static int (*SProcIVector[])(ClientPtr) = { SProcXSetClientPointer, /* 42 */ SProcXGetClientPointer, /* 43 */ SProcXiSelectEvent, /* 44 */ - SProcXExtendedGrabDevice /* 45 */ + SProcXExtendedGrabDevice, /* 45 */ + SProcXListDeviceProperties, /* 46 */ + SProcXQueryDeviceProperty, /* 47 */ + SProcXConfigureDeviceProperty, /* 48 */ + SProcXChangeDeviceProperty, /* 49 */ + SProcXDeleteDeviceProperty, /* 50 */ + SProcXGetDeviceProperty /* 51 */ }; /***************************************************************** diff --git a/Xi/xiproperty.c b/Xi/xiproperty.c new file mode 100644 index 000000000..832a4582d --- /dev/null +++ b/Xi/xiproperty.c @@ -0,0 +1,755 @@ +/* + * Copyright © 2006 Keith Packard + * Copyright © 2008 Peter Hutterer + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WAXIANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WAXIANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
