我想要一个带3个按钮的窗口,但这个按钮应该像单选按钮一样工作! 所以这是我的代码:
Rectangle {
id: sideButton
color: sideButtonMouseArea.containsMouse ? '#DDDDDD' : '#F4F4F4'
property string text: 'Button'
MouseArea {
id: sideButtonMouseArea
anchors.fill: parent
hoverEnabled: true
onClicked: {
parent.color = '#4872E8'
sideButtonLabel.color = '#E2EBFC'
}
}
Text {
id: sideButtonLabel
text: sideButton.text
font.pixelSize: 20
font.family: 'Tahoma'
anchors.centerIn: sideButton
color: '#787878'
}
}
我使用这个矩形代替按钮但是在2个时间点击其他按钮时会出现问题 我怎么能解决它?

此代码适用于我:
<强> MyRadioGroup.qml 强>
import QtQuick 1.0
QtObject {
property Item selected : null
}
<强> MyRadioButton.qml 强>
import QtQuick 1.0
Rectangle {
id: sideButton
property string text: 'Button'
property MyRadioGroup radioGroup
color: radioGroup.selected === sideButton ? '#E2EBFC' :
(sideButtonMouseArea.containsMouse ? '#DDDDDD' : '#F4F4F4')
MouseArea {
id: sideButtonMouseArea
anchors.fill: parent
hoverEnabled: true
onClicked: sideButton.radioGroup.selected = sideButton
}
Text {
id: sideButtonLabel
text: sideButton.text
font.pixelSize: 20
font.family: 'Tahoma'
anchors.centerIn: sideButton
color: radioGroup.selected === sideButton ? '#E2EBFC' : '#787878'
}
}
<强> main.qml 强>
import QtQuick 1.0
Rectangle {
height: 600
width: 600
MyRadioGroup {
id: radioGroup1
}
Column {
anchors.fill: parent
MyRadioButton {
anchors { left: parent.left; right: parent.right }
text: "Button 1"
radioGroup: radioGroup1
height: 100
}
MyRadioButton {
anchors { left: parent.left; right: parent.right }
text: "Button 2"
radioGroup: radioGroup1
height: 100
}
MyRadioButton {
anchors { left: parent.left; right: parent.right }
text: "Button 3"
radioGroup: radioGroup1
height: 100
}
MyRadioButton {
anchors { left: parent.left; right: parent.right }
text: "Button 4"
radioGroup: radioGroup1
height: 100
}
}
}
它的作用:我创建了容器MyRadioGroup
来保存当前选中的项目。然后,我声明性地将其selected
属性绑定到color
- s的MyRadioButton
属性,因此它会在每次selected
更改时更新。
说完之后,请检查一下,你的组件提供商还没有包含这样的东西---也许你正在重新发明轮子。
