Question

我有一个带有'YES'和'NO'按钮的对话框。我想在对话框外面按下关闭对话框并且也不会触发'NO'按钮信号（只需按'NO'按钮就可以触发它）。有可能吗？

Dialog {
    id: dialog
    title: "Save your Info?"
    width: parent.width/2
    modal: true
    closePolicy: Popup.CloseOnPressOutside
    standardButtons: Dialog.Yes | Dialog.No

    onAccepted: console.log("Yes clicked")
    onRejected: console.log("No clicked")
    onClosed: console.log("Dialog closed")
    Component.onCompleted: open()
}

现在，如果我点击对话框之外，它会打印：

qml：没有点击

qml：对话框已关闭

是否有可能只是通过点击对话关闭对话（实际取消它）而不是在关闭之前拒绝它？

更新：实际上，我只是希望通过点击外部为“是”，“否”和“取消”提供3个不同的信号

Answer 1

将模态更改为false（这样您可以在外面按住而closePolicy不是CloseOnPressOutside模式对话框会阻止您的按下），将closePolicy更改为其他任何内容（不是{{1}但是请不要将其保留为默认值。添加CloseOnPressOutside以处理外部对话框。

感谢您对穆罕默德的回应。但我试图找到更好的方法，最后我发现了这种方法。我希望它也可以帮助别人。

            TestCleanup();

    }

}

如何在对话框外点击有明显的信号？
