控件的宽度和高度可以自己设置，右侧的输入框的宽度会根据左侧文本的宽度自动设置

import QtQuick 2.14
import QtQuick.Controls 2.14
import QtQuick.Layouts 1.14

Rectangle{
    id: root

    width: 230
    height: 30

    //固定的文本
    property var labelText: "labelText"

    //用户输入的文本信息
    property var editableText: ""

    property var maxLength: 15

    RowLayout{
        anchors.fill: parent
        anchors.margins: 5
        spacing: 5

        Text {
            id: label
            text: labelText
            font.pointSize: 12
            verticalAlignment: Text.AlignVCenter
        }

        Rectangle {
            Layout.fillWidth: true
            height: parent.height

            color: "lightgray"
            border.color: "gray"
            border.width: 1
            radius: 2

            TextInput {
                text: editableText
                anchors.fill: parent
                anchors.margins: 2
                font.pointSize: 12
                focus: true
                maximumLength: maxLength
                verticalAlignment: Text.AlignVCenter
                onTextChanged: {
                    editableText = text
                    console.log(editableText)
                }
            }
        }
