\qmltype ProgressBarStyle
\inqmlmodule QtQuick.Controls.Styles
\since 5.1
\ingroup controlsstyling
\brief Provides custom styling for ProgressBar
Example:
\qml
ProgressBar {
value: slider.value
style: ProgressBarStyle {
background: Rectangle {
radius: 2
color: "lightgray"
border.color: "gray"
border.width: 1
implicitWidth: 200
implicitHeight: 24
}
progress: Rectangle {
color: "lightsteelblue"
border.color: "steelblue"
}
}
}
\endqml
Note that the example above is somewhat simplified and will not animate
an indeterminate progress bar. The following snippet demonstrates
how you can incorporate a custom animation for the indeterminate
state as well.
\code
progress: Rectangle {
border.color: "steelblue"
color: "lightsteelblue"
// Indeterminate animation by animating alternating stripes:
Item {
anchors.fill: parent
anchors.margins: 1
visible: control.indeterminate
clip: true
Row {
Repeater {
Rectangle {
color: index % 2 ? "steelblue" : "lightsteelblue"
width: 20 ; height: control.height
}
model: control.width / 20 + 2
}
XAnimator on x {
from: 0 ; to: -40
loops: Animation.Infinite
running: control.indeterminate
}
}
}
}
\endcode

/*! A value in the range [0-1] indicating the current progress. */

control.value / control.maximumValue
/*! This property holds the visible contents of the progress bar
