qml实现的侧边弹窗效果
在QML中,Popup是一种弹出式界面控件的基本类型,可以与Window或ApplicationWindow一起使用。一个基本的Popup示例可以如下所示:
```qml
import QtQuick.Window
import QtQuick.Controls
ApplicationWindow {
id: window
width: 400
height: 400
visible: true
Button {
text: "Open"
onClicked: popup.open()
}
Popup {
id: popup
x: 100
y: 100
width: 200
height: 300
modal: true
focus: true
closePolicy: Popup.CloseOnEscape | Popup.CloseOnPressOutsideParent
}
}
```
默认情况下,按下Escape或Back键会关闭Popup。如果您希望自定义处理这些事件,有两种解决方案:
1. 将Popup的closePolicy属性设置为不包括Popup.CloseOnEscape的值,这样按下退出键时不会关闭Popup。
2. 处理Keys的shortcutOverride信号,并在Popup之前接受事件。
Popup的closePolicy属性是一个枚举类型,决定了弹出窗口关闭的情况。以下是closePolicy的可能取值:
- Popup.NoAutoClose: Popup只会在手动指示时关闭。
- Popup.CloseOnPressOutside: 当鼠标在Popup外部按下时,Popup将关闭。
- Popup.CloseOnPressOutsideParent: 当鼠标在父级之外按下时,Popup将关闭。
- Popup.CloseOnReleaseOutside: 当鼠标离开Popup时,Popup将关闭。
- Popup.CloseOnReleaseOutsideParent: 当鼠标在父级之外释放时,Popup将关闭。
- Popup.CloseOnEscape: 当Popup具有焦点且按下退出键时,Popup将关闭。<em>1</em><em>2</em><em>3</em>
