修改的时候就在那两个ScrollBar里加样式一个 horizonBar,一个verticalBar,以下是个简单的例子：
1 import QtQuick 2.12 2 import QtQuick.Controls 2.12 3 import QtQuick.Controls.impl 2.12 4 5 ScrollBar { 6 id: control 7 8 property color handleNormalColor: "darkCyan" //滑块颜色 9 property color backgroundBarColor: "white" //背景颜色 10 property color handleHoverColor: Qt.lighter(handleNormalColor) 11 property color handlePressColor: Qt.darker(handleNormalColor) 12 13 implicitWidth: Math.max(implicitBackgroundWidth + leftInset + rightInset, 14 implicitContentWidth + leftPadding + rightPadding) 15 implicitHeight: Math.max(implicitBackgroundHeight + topInset + bottomInset, 16 implicitContentHeight + topPadding + bottomPadding) 17 18 //滑块样式 19 contentItem: Rectangle { 20 implicitWidth: control.interactive ? 10 : 2 21 implicitHeight: control.interactive ? 10 : 2 22 23 radius: width / 2 24 color: control.pressed 25 ?handlePressColor 26 :control.hovered 27 ?handleHoverColor 28 :handleNormalColor 29 30 opacity:(control.policy === ScrollBar.AlwaysOn || control.size < 1.0)?1.0:0.0 31 } 32 33 //背景 34 background: Rectangle { 35 implicitWidth: control.interactive ? 10 : 2 36 implicitHeight: control.interactive ? 10 : 2 37 color: backgroundBarColor 38 } 39 }
