Прост прогрес бар
Този много прост QML прогрес бар бе вдъхновен от примера, който идва с Qt. Направен е така, че да е много опростен и лек и да е подходящ дори за много малки размери. Ето така изглежда по подразбиране (със зеленият цвят на Qt ;-) )
Този прогрес бар се използва заедно с BusyIndicator в QML компонента ProgressSpinner, за да се получи приятен елемент, който може да показва активността и прогреса на дълги операции.
Реализация (SimpleProgressBar.qml):
import QtQuick 1.0
Item {
id: progressbar
property int minimum: 0
property int maximum: 100
property int value: 0
property color color: "#77B753"
width: 250; height: 23
clip: true
Rectangle {
id: border
anchors.fill: parent
anchors.bottomMargin: 1
anchors.rightMargin: 1
color: "transparent"
border.width: 1
border.color: parent.color
}
Rectangle {
id: highlight
property int widthDest: ( ( progressbar.width * ( value- minimum ) ) / ( maximum - minimum ) - 4 )
width: highlight.widthDest
Behavior on width {
SmoothedAnimation {
velocity: 1200
}
}
anchors {
left: parent.left
top: parent.top
bottom: parent.bottom
margins: 2
}
color: parent.color
}
}
Употреба:
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
}
}
