Simple Progress Bar

This very simple QML progress bar takes some inspiration form the progress bars example that ships with Qt. I have modified it to be a very plain and lightweight progress bar that is suitable for use even at very small sizes. This is what it looks like by default (with the Qt green colour ;) )
Simple progress bar
This progress bar is used along with the "BusyIndicator":http://developer.qt.nokia.com/wiki/Busy_Indicator_for_QML in the ProgressSpinner QML component to produce a nice QML component that can show activity and progress for long operations.


Implementation (SimpleProgressBar.qml):

<br />import QtQuick 1.0
<br />Item {<br /> id: progressbar
<br /> property int minimum: 0<br /> property int maximum: 100<br /> property int value: 0<br /> property color color: &quot;#77B753&amp;quot;
<br /> width: 250; height: 23<br /> clip: true
<br /> Rectangle {<br /> id: border<br /> anchors.fill: parent<br /> anchors.bottomMargin: 1<br /> anchors.rightMargin: 1<br /> color: &quot;transparent&amp;quot;<br /> border.width: 1<br /> border.color: parent.color<br /> }
<br /> Rectangle {<br /> id: highlight<br /> property int widthDest: ( ( progressbar.width * ( value</s> minimum ) ) / ( maximum - minimum ) - 4 )<br /> width: highlight.widthDest

Behavior on width {<br /> SmoothedAnimation {<br /> velocity: 1200<br /> }<br /> }

anchors {<br /> left: parent.left<br /> top: parent.top<br /> bottom: parent.bottom<br /> margins: 2<br /> }<br /> color: parent.color<br /> }<br />}<br />

Usage:


import QtQuick 1.0

Rectangle {
id: root
width: 640
height: 360

SimpleProgressBar {
id: progress
anchors.centerIn: progressSpinner
width: 100
height: 12
color: progressSpinner.color
value: 35
}
}
