import QtQuick 2.0
import QtQuick.VirtualKeyboard 2.0

Item {
    TextInput {
        id: input
        width: 200
        height: 40
        focus: true
        Keys.onReleased: {
            if (event.key === Qt.Key_Hide) {
                // 在此处处理隐藏按键事件
                console.log("Hide key pressed")
            }
        }
    }

    InputPanel {
        id: inputPanel
        visible: true
        y: input.height
        width: input.width
        height: contentItem.implicitHeight
    }
}
