[英]Qt/QML SwipeDelegate doesn't work properly on mobile devices (Android, iOS)
我是Qt / QML编程的新手,正在尝试使以下示例在移动设备上正常运行。 当我尝试“向右滑动”,然后点击“删除”按钮时,“ Listview-item”将不会被删除。 在台式机上一切正常,但在移动设备上无法正常工作。 谁能帮我解决我的问题?
import QtQuick 2.7
import QtQuick.Controls 2.0
ApplicationWindow {
id: appWindow
visible: true
ListView {
id: listView
anchors.fill: parent
model: ListModel {
ListElement { name: "Swipe Delegate - Test 1" }
ListElement { name: "Swipe Delegate - Test 2" }
ListElement { name: "Swipe Delegate - Test 3" }
ListElement { name: "Swipe Delegate - Test 4" }
}
delegate: SwipeDelegate {
id: swipeDelegate
text: model.name
width: parent.width
ListView.onRemove: SequentialAnimation {
PropertyAction {
target: swipeDelegate
property: "ListView.delayRemove"
value: true
}
NumberAnimation {
target: swipeDelegate
property: "height"
to: 0
easing.type: Easing.InOutQuad
}
PropertyAction {
target: swipeDelegate;
property: "ListView.delayRemove";
value: false
}
}
swipe.right: Label {
id: deleteLabel
text: qsTr("Delete")
color: "white"
verticalAlignment: Label.AlignVCenter
padding: 12
height: parent.height
anchors.right: parent.right
SwipeDelegate.onClicked: listView.model.remove(index)
background: Rectangle {
color: deleteLabel.SwipeDelegate.pressed ? Qt.darker("tomato", 1.1) : "tomato"
}
}
}
}
}
您可以在Rectangle中添加带有onClicked事件的MouseArea。 这是示例:
background: Rectangle {
color: deleteLabel.SwipeDelegate.pressed ? Qt.darker("tomato", 1.1) : "tomato"
MouseArea {
anchors.fill: parent
onClicked: listView.model.remove(index)
}
}
