详细描述
使用Qt D-Bus模块的应用程序通过导出对象向其他远程应用程序提供服务, 也可以调用函数和访问属性, 使用这些应用程序导出的服务.
Qt D-Bus总线模块提供了一个扩展 Qt 信号和槽函数 机制的接口, 允许连接到远程发出的信号或将本地信号连接到远程槽函数.
要使用此模块, 在应用程序中使用以下代码:
#include <QtDBus>
如果你使用qmake编译应用程序, 你可以在.pro文件加上以下代码, 链接Qt D-Bus库:
QT += dbus
注意: Qt D-Bus模块的源码位于 src/qdbus目录. 若从源码编译, 此模块在编译Qt工具时编译.
如何使用此模块, 详见 D-Bus.
