## Detailed Description

## Member Function Documentation

### `[explicit]` QDBusServer::QDBusServer(const QString &address, QObject *parent = nullptr)

Constructs a QDBusServer with the given address, and the given parent.

### `[explicit]` QDBusServer::QDBusServer(QObject *parent = nullptr)

Constructs a QDBusServer with the given parent. The server will listen for connections in `/tmp` (on Unix systems) or on a TCP port bound to localhost (elsewhere).

### `[virtual noexcept]` QDBusServer::~QDBusServer()

Destructs a QDBusServer

### QString QDBusServer::address() const

Returns the address this server is associated with.

### bool QDBusServer::isAnonymousAuthenticationAllowed() const

Returns true if anonymous authentication is allowed.

See also setAnonymousAuthenticationAllowed().

### bool QDBusServer::isConnected() const

Returns `true` if this QDBusServer object is connected.

If it isn't connected, you need to call the constructor again.

### QDBusError QDBusServer::lastError() const

Returns the last error that happened in this server.

This function is provided for low-level code.

### `[signal]` void QDBusServer::newConnection(const QDBusConnection &connection)

This signal is emitted when a new client connection connection is established to the server.

### void QDBusServer::setAnonymousAuthenticationAllowed(bool value)

If value is set to true, an incoming connection can proceed even if the connecting client is not authenticated as a user.

By default, this value is false.

See also isAnonymousAuthenticationAllowed().
