In this example, we call a method named "GetIntValue" on a D-Bus interface using a QDBusInterface object. The reply is stored in a QDBusReply object of type int. If the reply is valid, we can access the integer value using the value() method. If there is an error, we can retrieve the error message from the reply. Example 2: Retrieving a complex object from a D-Bus method callc++
In this example, we call a method named "GetDeviceInfo" on a D-Bus interface and receive a complex object in the form of a QVariantMap. We can access the individual values in the map using the [] operator and do something with them. The QDBusReply class is part of the QtDBus module, which is included in Qt 4 and later. To use this module, you need to include the following line in your C++ code:c++ #include
