在对话框中且VirtualKeyboard是基类，则无法点击TextField。
以下是代码：
Application Window如果我将 ApplicationWindow 更改为窗口，则不会出现问题，这是否是 v5.9.1 中的QT错误？
答案 0 :(得分：0)
ApplicationWindow提供了一个很好的额外图层overlay，您可以将其重新显示在内容其余部分之上的所有内容 - 恰好是VirtualKeyboard
InputPanel {
id: inputPanel
parent: ApplicationWindow.overlay // <-- This will do the trick
anchors.bottom:parent.bottom
anchors.left: parent.left
anchors.right: parent.right
visible: Qt.inputMethod.visible
}
