# qt_add_dbus_interfaces

Generates C++ sources implementing interfaces for D-Bus interface description files.

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_interfaces(<VAR> dbus_spec1 [dbus_spec2 ...])

If versionless commands are disabled, use `qt6_add_dbus_interfaces()` instead. It supports the same set of arguments as this command.

## Description

Generates C++ sources implementing D-Bus interfaces defined in `dbus_spec1`, `dbus_spec2`, where each argument needs to be the path to a valid D-Bus interface description file. The paths of the generated files are added to `<VAR>`.

For each argument, a call to the Qt D-Bus XML compiler (qdbusxml2cpp) in interface (proxy) mode is set up.

The generated C++ source files are named after the XML file: For the file `org.example.chat.xml` the generated header will be named `orgexamplechatinterface.h`.

## Options

Options can be set using `set_source_files_properties` on each of the file arguments:

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.
