The DBusCall is exported as a QObject to the QML environment. It is
intended as a declarative replacement for the callDBus method which used
to be exported on global scope in the QtQuick 1 world.
Example usage:
DBusCall {
id: dbus
service: "org.kde.KWin"
path: "/KWin"
method: "setCurrentDesktop"
arguments: [1]
Component.onCompleted: dbus.call()
}

/**
|
|
* @brief Qml export for providing a wrapper for sending a message over the DBus
|
|
* session bus.
|
|
*
|
|
* Allows to setup the connection arguments just like in QDBusMessage and supports
|
|
* adding arguments to the call. To invoke the message use the slot @link call.
|
|
*
|
|
* If the call succeeds the signal @link finished is emitted, if the call fails
|
|
* the signal @link failed is emitted.
|
|
*
|
|
* Note: the DBusCall always uses the session bus and performs an async call.
|
|
*
|
|
* Example on how to use in Qml:
|
|
* @code
|
|
* DBusCall {
|
|
* id: dbus
|
|
* service: "org.kde.KWin"
|
|
* path: "/KWin"
|
|
* method: "nextDesktop"
|
|
* Component.onCompleted: dbus.call()
|
|
* }
|
|
* @endcode
|
|
*
|
|
* Example with arguments:
|
|
* @code
|
|
* DBusCall {
|
|
* id: dbus
|
|
* service: "org.kde.KWin"
|
|
* path: "/KWin"
|
|
* method: "setCurrentDesktop"
|
|
* arguments: [1]
|
|
* Component.onCompleted: dbus.call()
|
|
* }
|
|
* @endcode
|
|
*
|
|
* Example with a callback:
|
|
* @code
|
|
* DBusCall {
|
|
* id: dbus
|
|
* service: "org.kde.KWin"
|
|
* path: "/KWin"
|
|
* method: "currentDesktop"
|
|
* onFinished: console.log(returnValue[0])
|
|
* }
|
|
* @endcode
|
