Flat风格的Qml滑动条

基于Qml的Slider控件修改而成。

滑动条代码

import QtQuick 2.0
import QtQuick.Controls 2.0
import QtGraphicalEffects 1.0

Slider {
    id: root

    property color checkedColor: "#3498DB"

    value: 0.5

    background: Rectangle {
        x: root.leftPadding
        y: root.topPadding + root.availableHeight / 2 - height / 2
        implicitWidth: 200
        implicitHeight: 12
        width: root.availableWidth
        height: implicitHeight
        radius: height / 2
        color: "#EBEDEF"

        Rectangle {
            width: root.visualPosition == 0 ? 0 : root.handle.x + root.handle.width / 2
            height: parent.height
            color: root.checkedColor
            radius: height / 2


            layer.enabled: root.hovered | root.pressed
            layer.effect: DropShadow {
                transparentBorder: true
                color: root.checkedColor
                samples: 8
            }
        }
    }

    handle: Rectangle {
        x: root.leftPadding + root.visualPosition * (root.availableWidth - width)
        y: root.topPadding + root.availableHeight / 2 - height / 2
        implicitWidth: root.background.implicitHeight + 6
        implicitHeight: implicitWidth
        radius: implicitWidth / 2
        color: root.pressed ? Qt.darker(root.checkedColor, 1.2) : root.checkedColor

        layer.enabled: root.hovered | root.pressed
        layer.effect: DropShadow {
            transparentBorder: true
            color: root.checkedColor
            samples: 10 /*20*/
        }
    }
}

滑动条样式代码

GridLayout {
    width: root.width
    rows: 3
    columns: 3

    Repeater {
        id: spinBoxRepeater
        model: ["#727CF5", "#0ACF97", "#F9375E",
                "#FFBC00", "#2B99B9", "#5A6268",
                "#EEF2F7", "#212730", "#3498DB"]

        Slider {
            checkedColor: modelData
            value: Math.random()
        }
    }
}
