qml中toolbox控件、ComboBox控件、PlainText实现及美化

本文主要是介绍qml中toolbox控件、ComboBox控件、PlainText实现及美化，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一. 内容简介

qml中toolbox控件、ComboBox控件、PlainText实现及美化

二. 软件环境

2.1vsCode

2.2Anaconda

version: conda 22.9.0

2.3pytorch

安装pytorch(http://t.csdnimg.cn/GVP23)

2.4QT 5.14.1

新版QT6.4,，6.5在线安装经常失败，而5.9版本又无法编译64位程序，所以就采用5.14.1这个用的比较多也比较稳定的一个版本。

QT编译器采用的是MSVC2017 64bit。

三.主要流程

3.1 toolbox代码

下面是toollbox代码，没有每页的内容，代码如下，图片就是图标图片，位置都留好了，只换图就可可以了，可以上网自己下载
使用代码

ToolBox{Layout.preferredWidth: 300 - 16Layout.leftMargin: 8Layout.preferredHeight: 600
}

实现代码，里面每个页面我都单独创建一个qml文件写的，如果想在一个文件里面写的话，就是我注释的那个代码，换成那个就可以了
