# qt_add_dbus_interface

Generates C++ sources implementing an interface for a D-Bus interface description file.

The command is defined in the `DBus` component of the `Qt6` package. Load the package with:

     find_package(Qt6 REQUIRED COMPONENTS DBus)

This command was introduced in Qt 6.0.

## Synopsis

     qt_add_dbus_interface(<VAR> dbus_spec basename)

If versionless commands are disabled, use `qt6_add_dbus_interface()` instead. It supports the same set of arguments as this command.

## Description

Generates C++ sources implementing an interface for a D-Bus interface description file defined in `dbus_spec`. The generated files are named after `basename`: `basename.h`, `basename.cpp`, `basename.moc`. The paths of the files are added to `<VAR>`.

The function sets up a call to the Qt D-Bus XML compiler (qdbusxml2cpp) in interface (proxy) mode. By default, `qdbusxml2cpp` generates a C++ class named after the interface name, with a namespaced alias:

D-Bus Interface Name | Class name | Namespaced name
--- | --- | ---
`org.example.chat` | `OrgExampleChatInterface` | `org.example.chat`

## Options

Options can be set using `set_source_files_properties` on the `dbus_spec`:

Option | Value | Description
--- | --- | ---
`CLASSNAME` | `class_name` | Override the default interface class name with `class_name`.
`NO_NAMESPACE` | boolean | Do not generate the namespaced name if set to `ON`.
`INCLUDE` | `path` | Add an `#include "path"` in the generated code.
