QML之TabWidget

新年快乐。

明天就上班啦。也该继续学习了。同时期待13日的到来，看看传说的Meego设备是不是浮云。 网上都传"那货不是手机了"

今天又发现一个有用的example呵呵.其实就是一个Tab控件.

//TabWidget.qml import Qt 4.7 Item { id: tabWidget default property alias content: stack.children //将tab页集合设置一个默认属性 property int current: 0 onCurrentChanged: setOpacities() Component.onCompleted: setOpacities() function setOpacities() { for(var i = 0; i < content.length; ++i) { content[i].opacity = (i == current ? 1 : 0);//将当前的tab设置为非透明,其余透明 } } Row { //此组件为tab选项 id: header Repeater { model: content.length delegate: Rectangle { width: tabWidget.width / content.length height: 36 color: "#e3e3e3" Rectangle { //此组件为tab选项和tab页之间的一条线 width: tabWidget.width; height: 1 anchors { bottom: parent.bottom; bottomMargin: 1} color: "#abc2c2" } BorderImage { //tab选项图片 anchors { fill: parent; leftMargin: 2; topMargin: 5; rightMargin: 1} border { left: 7; right: 7} source: tabWidget.current == index? "tab.png" : "unselect.png" } Text { //tab选项的文本 horizontalAlignment: "AlignHCenter"; verticalAlignment: "AlignVCenter" anchors.fill: parent text: content[index].title elide: Text.ElideRight font.bold: tabWidget.current == index } MouseArea { anchors.fill: parent onClicked: tabWidget.current = index //存储当前选中tab页 } } } } Item { //此组件为tab页 id: stack width: tabWidget.width anchors.top: header.bottom anchors.bottom: tabWidget.bottom } }

//main.qml import Qt 4.7 TabWidget { id: tabs width: 640; height: 480 Rectangle { //第一个tab页 property string title: "Red" anchors.fill: parent color: "#e3e3e3" Rectangle { anchors.fill: parent; anchors.margins: 20 //tab边框与父容器的距离 color: "#7fff7f" Text { width: parent.width - 20 anchors.centerIn: parent; horizontalAlignment: "AlignHCenter" text: "Roses are red" font.pixelSize: 20 wrapMode: Text.WordWrap } } } Rectangle { //第二个tab页 property string title: "Green" anchors.fill: parent color: "#e3e3e3" Rectangle { anchors.fill: parent; anchors.margins: 20 color: "#7fff7f" Text { width: parent.width - 20 anchors.centerIn: parent; horizontalAlignment: "AlignHCenter" text: "Flower stems are green" font.pixelSize: 20 wrapMode: Text.WordWrap } } } Rectangle { //第三个tab页 property string title: "Blue" anchors.fill: parent color: "#e3e3e3" Rectangle { anchors.fill: parent; anchors.margins: 20 color: "#7fff7f" Text { width: parent.width - 20 anchors.centerIn: parent; horizontalAlignment: "AlignHCenter" text: "Violets are blue" font.pixelSize: 20 wrapMode: Text.WordWrap } } } }
