问题描述
我正在尝试创建像 this 这样的手风琴 qml 控件.首先我认为我可以使用组合框并对其进行自定义,但现在我认为这是不可能的.我可以使用任何标准控件吗?如果没有,你能帮我控制结构吗?
I'm trying to create accordion qml control like this. First I thought that I can use combobox and customize it but now I think it is impossible. Is there any standerd control that I can use? If not can you help me with controls structure?
推荐答案
只是玩QML
PanelItem.qml
PanelItem.qml
import QtQuick 2.7
import QtQuick.Layouts 1.2
Item {
default property var contentItem: null
property string title: "panel"
id: root
Layout.fillWidth: true
height: 30
Layout.fillHeight: current
property bool current: false
ColumnLayout {
anchors.fill: parent
spacing: 0
Rectangle {
id: bar
Layout.fillWidth: true
height: 30
color: root.current ? "#81BEF7" : "#CEECF5"
Text {
anchors.fill: parent
anchors.margins: 10
horizontalAlignment: Text.AlignLeft
verticalAlignment: Text.AlignVCenter
text: root.title
}
Text {
anchors{
right: parent.right
top: parent.top
bottom: parent.bottom
margins: 10
}
horizontalAlignment: Text.AlignRight
verticalAlignment: Text.AlignVCenter
text: "^"
rotation: root.current ? "180" : 0
}
MouseArea {
anchors.fill: parent
cursorShape: Qt.PointingHandCursor
onClicked: {
root.current = !root.current;
if(root.parent.currentItem !== null)
root.parent.currentItem.current = false;
root.parent.currentItem = root;
}
}
}
Rectangle {
id: container
Layout.fillWidth: true
anchors.top: bar.bottom
implicitHeight: root.height - bar.height
clip: true
Behavior on implicitHeight {
PropertyAnimation { duration: 100 }
}
}
Component.onCompleted: {
if(root.contentItem !== null)
root.contentItem.parent = container;
}
}
}
用法:
import QtQuick 2.7
import QtQuick.Layouts 1.2
import QtQuick.Window 2.0
Window {
visible: true
width: 400
height: 400
ColumnLayout {
anchors.fill: parent
spacing: 1
property var currentItem: null
PanelItem {
title: "Panel 1"
Rectangle {
color: "orange"
anchors.fill: parent
}
}
PanelItem {
title: "Panel 2"
Rectangle {
color: "lightgreen"
anchors.fill: parent
}
}
PanelItem {
title: "Panel 3"
Rectangle {
color: "lightblue"
anchors.fill: parent
}
}
PanelItem {
title: "Panel 4"
Rectangle {
color: "yellow"
anchors.fill: parent
}
}
Item {
Layout.fillWidth: true
Layout.fillHeight: true
}
}
}
