\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
