    enum QDBus:: CallMode

    This enum describes the various ways of placing a function call. The valid modes are:

    常量 描述
    QDBus::NoBlock 0 Place the call but don't wait for the reply (the reply's contents will be discarded).
    QDBus::Block 1 Don't use an event loop to wait for a reply, but instead block on network operations while waiting. This means the user-interface may not be updated until the function returns.
    QDBus::BlockWithGui 2 Use the Qt event loop to wait for a reply. This means that the user-interface will stay responsive (processing input events), but it also means other events may happen, like signal delivery and other D-Bus method calls.
    QDBus::AutoDetect 3 Automatically detect if the called function has a reply.

    When using BlockWithGui, applications must be prepared for reentrancy in any function.
