Introduction

As the previous article : How to use QVibra to enable vibration in QML. This article will show another way to implement vibration using QML

Step by step

In the project file, put these settings first:

...
 
CONFIG += mobility
MOBILITY += feedback
 
...

Next step, I'll put some of these code below to main.qml file

import QtMobility.feedback 1.1
 
PageStackWindow {
    id: appWindow
 
    HapticsEffect {
        id: rumbleEffect
        attackIntensity: 0.0
        attackTime: 250
        intensity: 1.0
        duration: 250 // set up the duration here, in millisecond
        fadeTime: 250
        fadeIntensity: 0.0
    }
}

Ok, now wherever you want to start the vibration, just easily call the rumbleEffect

...
appWindow.rumbleEffect.start();
...
