Qt Quick Extras Overview

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

快速入门

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

qmake
make
make install

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

import QtQuick.Extras 1.4

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

CircularGauge	A gauge that displays a value within a range along an arc
Gauge	A straight gauge that displays a value within a range
Picture	An indicator that displays a colorized QPicture icon
StatusIndicator	显示活动 (或不活动) 状态的指示器

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
    }
}
