Questions tagged [qdbus]

The QDBus namespace, part of the Qt framework, contains miscellaneous identifiers used throughout the QtDBus library.

The QDBus namespace covers the identifiers used in the QtDBus module.

QtDBus is the Qt bindings to the D-Bus inter-process communication system. The QtDBus module provides a native interface to D-Bus using the Qt signals and slots paradigm.

Qt documentation lists the module as being Unix-only but recent versions of D-Bus are supported on Windows and the QtDBus module can be enabled Windows with minimal effort.
