D-Bus入门（四）——实现ofono代码下的python测试文件activite-context

一、参考列表

meego-cellular-ofono-qt

connman-qt
meego-ux-setting中的cellularSetting部分

合计来说一共就这三个包含了，connman-server、connman-manager、org.ofono.connectcontext、org.ofono.connectmanager四种d-bus的各种接口的各种使用方法

dbus之xml文件参考地址

二、代码

    connectcontext.xml

system(qdbusxml2cpp -c ConnectionContext -p connectioncontext -N connectioncontext.xml)

connectmanager.xml

由于QArrayOfPathProperties总是出错，所以放弃了使用XML的代理d-bus的实现方法。
