# Qt D-Bus Viewer

The Qt D-Bus Viewer (`qdbusviewer`) is a tool that lets you introspect D-Bus objects and messages. You can choose between the system bus and the session bus. Click on any service on the list on the left side to see all the exported objects.

You can invoke methods by double-clicking on them. If a method takes one or more IN parameters, a property editor opens.

Right-click on a signal to connect to it. All emitted signals including their parameters are output in the message view on the lower side of the window.

## Running Qt D-Bus Viewer

To run Qt D-Bus Viewer, execute the `qdbusviewer` tool in the installation directory of the respective Qt version. For the Qt 6.9.3 Linux/X11 installation using the Qt Online Installer, the tool is at:

     <INSTALL_DIR>/6.9.3/gcc_64/bin/qdbusviewer
