# Qt Quick Extras Overview

Qt Quick Extras provide a set of UI controls to create user interfaces in Qt Quick.

## Getting Started

### Building

If you are building Qt Quick Extras from source, you can follow the steps used for most Qt modules:

      qmake
      make
      make install

### Using the Controls

The QML types can be imported into your application using the following import statement in your `.qml` file.

      import QtQuick.Extras 1.4

## Interactive controls

DelayButton | A checkable button that triggers an action when held in long enough
Dial | A circular dial that is rotated to set a value
PieMenu | A popup menu that displays several menu items along an arc
ToggleButton | A push button that toggles between two states
Tumbler | A control that can have several spinnable wheels, each with items that can be selected

## Non-interactive controls

CircularGauge | A gauge that displays a value within a range along an arc
Gauge | A straight gauge that displays a value within a range
StatusIndicator | An indicator that displays active or inactive states
Picture | An indicator that displays a colorized QPicture icon

## Creating a basic example

A basic example of a QML file that makes use of controls is shown here:

      import QtQuick 2.2
      import QtQuick.Extras 1.4

      Rectangle {
          DelayButton {
              anchors.centerIn: parent
          }
      }

For an interactive showcase of the controls provided by Qt Quick Extras, you can look at the Gallery example.
