我在这里做错了什么。使用自定义委托,我的项目在列表视图中彼此重叠。这就是我得到的...
这是我想做的...
QML
import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.3
Frame {
ListView {
implicitWidth: 250
implicitHeight: 250
clip: true
model: ListModel {
ListElement {
done: true
description: "Wash the car this could be a really long message with some multiline support\n we will see how it works."
}
ListElement {
done: false
description: "Fix the car"
}
ListElement {
done: false
description: "Sell the car"
}
ListElement {
done: true
description: "Wash the car"
}
ListElement {
done: false
description: "Fix the car"
}
ListElement {
done: false
description: "Sell the car"
}
ListElement {
done: true
description: "Wash the car"
}
ListElement {
done: false
description: "Fix the car"
}
ListElement {
done: false
description: "Sell the car"
}
}
delegate: Row {
spacing: 6
width: parent.width
Rectangle {
id: newsicon
width: 16
height: 16
color: "steelblue"
}
Column {
Rectangle {
color: "lightgrey"
Label {
id: messageText
text: model.description
width: parent.width
wrapMode: Label.Wrap
}
Label {
id: dateText
text: "Dec 20, 2019"
wrapMode: Label.Wrap
}
}
}
}
ScrollBar.vertical: ScrollBar {
active: true
}
}
}
答案 0 :(得分:2)
实际上,您的问题是将标签放置在大小为零的不可见矩形内(因为它具有height==0
和width==0
),都位于位置(0, 0)
。而不是将Label
放入Column
中,而是将Rectangle
放入其中。这就是为什么您要重叠的原因。
我个人建议您使用Layouts
,例如:
Frame {
anchors.centerIn: parent
ListView {
implicitWidth: 250
implicitHeight: 250
clip: true
model: listModel
delegate: RowLayout {
Rectangle {
id: newsicon
width: 16
height: 16
color: "steelblue"
}
ColumnLayout {
Layout.fillWidth: true
spacing: 0
Label {
id: messageText
text: model.description
width: parent.width
wrapMode: Label.WrapAtWordBoundaryOrAnywhere
}
Label {
id: dateText
text: "Dec 20, 2019"
font.italic: true
color: "grey"
wrapMode: Label.WrapAtWordBoundaryOrAnywhere
}
}
}
ScrollBar.vertical: ScrollBar { active: true }
}
}
您将拥有:
