dbus 概念
--翻遍了google和百度，就这个图对入门帮助最大，dbus的文档真难找
fcitx 概念
dbus-send 命令行
/inputmethod --对象路径
org.freedesktop.DBus.Properties --interface
--dest=org.fcitx.Fcitx //名称
dbus-send --session --dest=org.fcitx.Fcitx --print-reply /inputmethod org.freedesktop.DBus.Properties.GetAll string:org.fcitx.Fcitx.InputMethod method return time=1589505703.719201 sender=:1.4 -> destination=:1.76 serial=218 reply_serial=2array [ dict entry( string "IMList"variant array [ struct{ string "键盘" string "fcitx-keyboard-us" string "en"boolean true} struct{ string "拼音" string "pinyin" string "zh_CN"boolean true} struct{ string "双拼" string "shuangpin" string "zh_CN"boolean true} struct{ string "五笔字型" string "wubi" string "zh_CN"boolean true} struct{ string "新酷音" string "chewing" string "zh_TW"boolean true} struct{ string "中州韻" string "rime" string "zh_TW"boolean true} struct{ string "讯飞输入法" string "iflyime" string "zh_CN"boolean false} struct{ string "五笔拼音" string "wbpy" string "zh_CN"boolean false} ] ) dict entry( string "CurrentIM"variant string "fcitx-keyboard-us") ]
#获取当前的输入法
uos@uos-PC:~$ dbus-send --session --dest=org.fcitx.Fcitx --print-reply /inputmethod org.fcitx.Fcitx.InputMethod.GetCurrentIM
method return time=1589506396.672512 sender=:1.4 -> destination=:1.81 serial=299 reply_serial=2
string "fcitx-keyboard-us
#设置为chewin 输入法
uos@uos-PC:~$ dbus-send --session --dest=org.fcitx.Fcitx --print-reply /inputmethod org.fcitx.Fcitx.InputMethod.SetCurrentIM string:chewing
method return time=1589506465.397429 sender=:1.4 -> destination=:1.82 serial=317 reply_serial=2
uos@uos-PC:~$
#gdbus 用法
gdbus call --session --dest com.deepin.daemon.Keybinding --object-path /com/deepin/daemon/Keybinding --method com.deepin.daemon.Keybinding.ListAllShortcuts
cmd ==>dbus-send --session --dest=org.fcitx.Fcitx --print-reply /inputmethod org.freedesktop.DBus.Properties.GetAll string:org.fcitx.Fcitx.InputMethod
另一个例子
uos@uos-PC:~/tmp$ dbus-send --session --dest=com.deepin.daemon.InputDevices --print-reply /com/deepin/daemon/InputDevice/Mouse org.freedesktop.DBus.Properties.GetAll string:com.deepin.daemon.InputDevice.Mouse method return time=1612511729.341407 sender=:1.177 -> destination=:1.297 serial=55919 reply_serial=2array [ dict entry( string "MotionAcceleration"variant double 1) dict entry( string "MotionScaling"variant double 10) dict entry( string "DoubleClick"variant int32 400) dict entry( string "DisableTpad"variant boolean false) dict entry( string "NaturalScroll"variant boolean false) dict entry( string "AdaptiveAccelProfile"variant boolean true) dict entry( string "Exist"variant boolean true) dict entry( string "LeftHanded"variant boolean true) dict entry( string "MiddleButtonEmulation"variant boolean false) dict entry( string "DragThreshold"variant int32 8) dict entry( string "MotionThreshold"variant double 1) dict entry( string "DeviceList"variant string "[{"Id":7,"Name":"VMware VMware Virtual USB Mouse","TrackPoint":false},{"Id":9,"Name":"VirtualPS/2 VMware VMMouse","TrackPoint":false}]") ]
设置鼠标左键
uos@uos-PC:~/tmp$ dbus-send --session --dest=com.deepin.daemon.InputDevices --print-reply /com/deepin/daemon/InputDevice/Mouse org.freedesktop.DBus.Properties.Set string:com.deepin.daemon.InputDevice.Mouse string:LeftHanded variant:boolean:truemethod return time=1612513318.004456 sender=:1.177 -> destination=:1.311 serial=63883 reply_serial=2
python version
import dbus
bus = dbus.SystemBus()
hci0 = bus.get_object('org.bluez', '/org/bluez/hci0')
props = dbus.Interface(hci0, 'org.freedesktop.DBus.Properties')
props.Set('org.bluez.Adapter1', 'Discoverable', True)
dbus signal的处理方法
demo代码参考
https://github.com/sgh/dbus-examples
命令行
signal time=1622515858.073001 sender=:1.719 -> destination=(null destination) serial=77 path=/com/burtonini/dbus/ping; interface=com.burtonini.dbus.Signal; member=Ping
string "Ping!"
dbus-send --type=signal /com/burtonini/dbus/ping com.burtonini.dbus.Signal.Ping string:"Ping"
dbus-monitor | grep -e EntryAdd -e EntryRemove
