From 32132312985e3a7f63444dcd4b54f821520a6042 Mon Sep 17 00:00:00 2001 From: Richard Grenville Date: Sat, 19 Jan 2013 20:20:27 +0800 Subject: Feature #80: D-Bus support - Add D-Bus support. Currently 7 methods are available: "reset" (same as SIGUSR1), "list_win" (list the windows compton manages), "win_get" (get a property of the window), "win_set" (set a property of the window), "find_win" (find window based on client window / focus), "opts_get" (get the value of a compton option), and "opts_set" (set the value of a compton option), together with 4 signals: "win_added", "win_destroyed", "win_mapped", "win_unmapped". - D-Bus support depends on libdbus. - As there are many items and my time is tight, no much tests are done. Bugs to be expected. - Create a new header file `common.h` that contains shared content. - Fix some bugs in timeout handling. - Update file headers in all source files. - Re-enable --unredir-if-possible on multi-screen set-ups, as the user could turn if off manually anyway. - Check if the window is mapped in `repair_win()`. - Add ps->track_atom_lst and its handlers, to prepare for the new condition format. - Known issue 1: "win_get", "win_set", "opts_get", "opts_set" support a very limited number of targets only. New ones will be added gradually. - Known issue 2: Accidental drop of D-Bus connection is not handled. - Known issue 3: Introspection does not reveal all available methods, because some methods have unpredictable prototypes. Still hesitating about what to do... - Known issue 4: Error handling is not finished yet. Compton does not always reply with the correct error message (but it does print out the correct error message, usually). --- dbus.c | 920 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 920 insertions(+) create mode 100644 dbus.c (limited to 'dbus.c') diff --git a/dbus.c b/dbus.c new file mode 100644 index 000000000..16be7cc8f --- /dev/null +++ b/dbus.c @@ -0,0 +1,920 @@ +/* + * Compton - a compositor for X11 + * + * Based on `xcompmgr` - Copyright (c) 2003, Keith Packard + * + * Copyright (c) 2011-2013, Christopher Jeffrey + * See LICENSE for more information. + * + */ + +#include "dbus.h" + +/** + * Initialize D-Bus connection. + */ +bool +cdbus_init(session_t *ps) { + DBusError err = { };
