運行截圖如下：

此時對應的源碼如下：

正確實例

運行截圖如下：

要注意的地方，在Row里面每一個都要指明寬度和高度：

這里是把Type in your first name的指明了！

width: firstNameTextId.implicitWidth + 20 height: firstNameTextId.implicitHeight + 20

源碼如下：

import QtQuick 2.9 import QtQuick.Window 2.2Window {visible: truewidth: 640height: 480title: qsTr("Hello World")Row{x: 10y: 10spacing: 10Rectangle{id: firstNameRectIdwidth: firstNameLabelId.implicitWidth + 20height: firstNameLabelId.implicitHeight + 20color: "beige"Text {id: firstNameLabelIdanchors.centerIn: parenttext: qsTr("FistName: ")}}Rectangle{id: firstNameTextRectIdcolor: "beige"width: firstNameTextId.implicitWidth + 20height: firstNameTextId.implicitHeight + 20TextInput{id: firstNameTextIdanchors.centerIn: parentfocus: truetext: "Type in your first name"onEditingFinished: {console.log("The first name changed to : " + text)}}}} }
