This example is part of a series of examples that demonstrate method proxy calls and adapter stubs. This group of examples are:
callee_c.cpp
- A dbus object interface created with the dbus C API callee_raw.cpp
- Manually handling the loop and callbacks similar to the C API example callee_dispatched.cpp
- Dispatched callbacks with manual demarshalling callee.cpp
- Dispatched callbacks with automatic demarshalling to a connected slot callee_2.cpp
- Similar to callee.cpp but with a void(void) method in the interface callee_object.cpp
- Dispatched callbacks with automatic demarshalling to connected slots that are members of a class instance (class knows nothing of DBus) callee_object_inherited.cpp
- Dispatched callbacks with automatic demarshalling to a class derived from Object caller_c.cpp
- Calling a proxy method with the dbus C API caller_raw.cpp
- Calling a proxy method with a manual loop similar to the C API example caller_dispatched.cpp
- Calling a proxy method using a dispatcher caller_object.cpp
- Calling a proxy method of a class derived from ObjectProxy Here is this example:
