Nemo QML Plugin D-Bus
API DocumentationExamples
There are a number of examples which demonstrate how to use various aspects of the API.
Calling a function on a session bus object
This code snippet talks to the profile daemon and sets the current profile to silent:
import QtQuick 2.0
import Nemo.DBus 2.0
Item {
DBusInterface {
id: profiled
service: 'com.nokia.profiled'
iface: 'com.nokia.profiled'
path: '/com/nokia/profiled'
}
Component.onCompleted: {
// Call the "set_profile" method here
profiled.call('set_profile', ['silent']);
}
}Calling a function and getting its return value
Because function calls are asynchronous, we need to provide a callback to be called when the function result is available:
import QtQuick 2.0
import Nemo.DBus 2.0
Item {
DBusInterface {
id: profiled
service: 'com.nokia.profiled'
iface: 'com.nokia.profiled'
path: '/com/nokia/profiled'
}
Component.onCompleted: {
// Call the "get_profile" method without arguments, and
// when it returns, call the passed-in callback method
profiled.typedCall('get_profile', [], function (result) {
// This will be called when the result is available
console.log('Got profile: ' + result);
});
}
}Listening to signals on a D-Bus object
import QtQuick 2.0
import Nemo.DBus 2.0
Item {
DBusInterface {
id: profiled
service: 'com.nokia.profiled'
iface: 'com.nokia.profiled'
path: '/com/nokia/profiled'
signalsEnabled: true
function profile_changed(changed, active, profile, values) {
if (changed && active)
console.log("Profile changed to:", profile)
}
}
}
