## Detailed Description

Example:

      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"
              }
          }
      }

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.

      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
                  }
              }
          }
      }
