\brief Provides custom styling for BusyIndicatorStyle
You can create a busy indicator by replacing the "indicator" delegate
of the BusyIndicatorStyle with a custom design.
Example:
\qml
BusyIndicator {
style: BusyIndicatorStyle {
indicator: Image {
visible: control.running
source: "spinner.png"
RotationAnimator on rotation {
running: control.running
loops: Animation.Infinite
duration: 2000
from: 0 ; to: 360
}
}
}
}
\endqml
*/
Style {
id: indicatorstyle
/*! The \l BusyIndicator this style is attached to. */
readonly property BusyIndicator control: __control
/*! This defines the appearance of the busy indicator. */
property Component indicator: Item {
id: indicatorItem
implicitWidth: 48
implicitHeight: 48
opacity: control.running ? 1 : 0
Behavior on opacity { OpacityAnimator { duration: 250 } }
Image {
anchors.centerIn: parent
anchors.alignWhenCentered: true
width: Math.min(parent.width, parent.height)
height: width
source: width <= 32 ? "images/spinner_small.png" :
width >= 48 ? "images/spinner_large.png" :
"images/spinner_medium.png"
RotationAnimator on rotation {
duration: 800
loops: Animation.Infinite
from: 0
to: 360
running: indicatorItem.visible && (control.running || indicatorItem.opacity > 0);
}
}
}
/*! \internal */
property Component panel: Item {
anchors.fill: parent
implicitWidth: indicatorLoader.implicitWidth
implicitHeight: indicatorLoader.implicitHeight
Loader {
id: indicatorLoader
sourceComponent: indicator
anchors.centerIn: parent
width: Math.min(parent.width, parent.height)
height: width
}
}
