成员枚举类型说明

◆ RotationDirection

enum Dtk::Widget::DLoadingIndicator::RotationDirection

The RotationDirection enum contains the possible rotation directions of the DLoadingIndicator widget.

枚举值
Clockwise	the rotation is clockwise
Counterclockwise	the rotation is counterclockwise

构造及析构函数说明

◆ DLoadingIndicator()

Dtk::Widget::DLoadingIndicator::DLoadingIndicator ( QWidget * parent = 0 )

DLoadingIndicator::DLoadingIndicator constructs an instance of DLoadingIndicator. parent is passed to QGraphicsView constructor.

DLoadingIndicator::DLoadingIndicator 函数是 DLoadingIndicator 的构造函数。 parent 指定了控件的父控件。

成员函数说明

◆ direction()

DLoadingIndicator::RotationDirection Dtk::Widget::DLoadingIndicator::direction ( ) const

DLoadingIndicator::direction

◆ setAniEasingCurve

void Dtk::Widget::DLoadingIndicator::setAniEasingCurve ( const QEasingCurve & easing )

slot

DLoadingIndicator::setAniEasingCurve sets an easing curve on the loading animation. easing

This property defines the easing curve of the animation. By default, a linear easing curve is used, resulting in linear interpolation. Other curves are provided, for instance, QEasingCurve::InCirc, which provides a circular entry curve. Another example is QEasingCurve::InOutElastic, which provides an elastic effect on the values of the interpolated variant.

DLoadingIndicator::setAniEasingCurve 是对 DLoadingIndicator::setAniEasingType 的补充，使用者除了使用 QEasingCurve::Type 中提供的几种预设的动画曲线，可以自定义 QEasingCurve 来实现更为灵巧的动画。

◆ start

void Dtk::Widget::DLoadingIndicator::start ( )

slot

DLoadingIndicator::start starts the loading animation.

DLoadingIndicator::start 启动旋转动画。

◆ stop

void Dtk::Widget::DLoadingIndicator::stop ( )

slot

DLoadingIndicator::stop stops the loading animation.

DLoadingIndicator::stop 停止旋转动画。

属性说明

◆ aniDuration

Dtk::Widget::DLoadingIndicator::aniDuration

readwrite

This property holds the duration of the loading animation.

DLoadingIndicator::aniDuration 属性用来控制旋转动画的周期。

◆ aniEasingType

Dtk::Widget::DLoadingIndicator::aniEasingType

readwrite

This property holds the easing type of the easing curve used by the loading animation.

DLoadingIndicator::aniEasingType 属性用来控制旋转动画的动画曲线。

参见: setAniEasingCurve

◆ backgroundColor

Dtk::Widget::DLoadingIndicator::backgroundColor

readwrite

This property holds the background color of this widget.

DLoadingIndicator::backgroundColor 属性用来控制 DLoadingIndicator 控件的背景色。

◆ direction

Dtk::Widget::DLoadingIndicator::direction

readwrite

This property holds the direction used while doing the rotation animation.

DLoadingIndicator::direction 用来控制旋转动画的旋转方向。

默认为顺时针方向。

参见: DLoadingIndicator::RotationDirection

◆ imageSource

Dtk::Widget::DLoadingIndicator::imageSource

readwrite

This property holds the image to be rendered as the content of the loading indicator.

DLoadingIndicator::imageSource 属性用来生成旋转动画中使用的图像。

参见: widgetSource

◆ loading

Dtk::Widget::DLoadingIndicator::loading

readwrite

This property holds the animation state.

DLoadingIndicator::loading 属性用来控制动画是否开启。

It returns true if the animation is running, false otherwise, you can also set value on this property to run or stop the animation.

设置为 true 开始动画， false 停止动画。

参见: start(), stop()

◆ rotate

Dtk::Widget::DLoadingIndicator::rotate

readwrite

This property holds the current rotation of the content.

DLoadingIndicator::rotate 属性用来控制当前控件内容旋转的角度。

This property is usually used to correct the rotation of the content after calling DLoadingIndicator::stop to stop the animation.

参见: QGraphicsItem::rotation

◆ smooth

Dtk::Widget::DLoadingIndicator::smooth

readwrite

This property holds whether the rendered content are antialiased or smoothly filtered.

DLoadingIndicator::smooth 属性代表是否要对控件启用平滑处理。

Smooth filtering gives better visual quality, but it may be slower on some hardware.

平滑处理后，控件会被进行反锯齿或者进行遮罩以达到更好的显示效果，但是在性能较差的机器上会比较慢。

◆ widgetSource

Dtk::Widget::DLoadingIndicator::widgetSource

readwrite

This property holds the widget to be rendered as the content of the loading indicator.

DLoadingIndicator::widgetSource 属性用来生成旋转动画中使用的图像。

参见: imageSource
