我们知道ListView在QML应用中扮演非常重要的角色。看看我们的很多的应用都是在使用ListView。那么当我们点击ListView中的item并导航到另外一个页面呢？其实这样的方法有很多。在这篇文章中，我们来介绍其中的几种。开发者可以参照其中的设计，或自己想出更好的设计。
ListView {
id: listview
clip: true
anchors.fill: parent
model:mymodel
header: Text {
text: "This is the header"
font.pixelSize: 30
Rectangle {
anchors.top: parent.bottom
width: listview.width
height: units.gu(0.4)
color: "blue"
}
}
delegate: MyDelegate {}
footer: Text {
text: "This is the footer"
font.pixelSize: 30
}
}
Item {
id: popup
visible: false
clip: true
property url loadUrl
onLoadUrlChanged: {
opacity = 0;
visible = (loadUrl == '' ? false : true);
console.log("opacity: " + opacity );
console.log("visible: " + visible );
}
anchors.fill: parent
Rectangle {
id: bg
anchors.fill: parent
color: "white"
}
MouseArea{
anchors.fill: parent
enabled: popup.visible
//Eats mouse events
}
Loader{
focus: true
source: popup.loadUrl
width: parent.width
height: parent.height -toolbar.height
}
Rectangle {
id: toolbar
width: parent.width
height: units.gu(4)
anchors.bottom: parent.bottom
color: "blue"
Icon {
name: "previous"
width: units.gu(3.5)
height: units.gu(3.5)
MouseArea {
anchors.fill: parent
onClicked: {
popup.loadUrl = "";
ani.running = true;
}
}
}
}
NumberAnimation on opacity {
id: ani

to: 1

}
}
}import QtQuick 2.0
