Type Documentation

enum QDBus::CallMode

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

ConstantValueDescription
QDBus::NoBlock0Place the call but don't wait for the reply (the reply's contents will be discarded).
QDBus::Block1Don'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::BlockWithGui2Use 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::AutoDetect3Automatically detect if the called function has a reply.

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