前言

以前用的Qt5.15.2之前的版本，QtCreator默认的工程文件是*.pro，现在用5.15.2创建工程默认的工程文件是CMameList.txt,当然在创建项目时，仍然可以使用pro工程文件用QtCreator打开CMakeList.txt
以前用习惯了pro文件，现在改成CMakeList很不习惯，现在我们在CMakeList.txt中加入资源文件

一、加入图片资源

1.首先，在Qt项目里创建一个目录image，然后将图片资源放image目录中

2.在Qt creator中创建resource file
鼠标右键项目listWidgetSplitter> Add New… > Qt > Qt Resource File > 输入文件名Resources，->next

3.新建资源文件.qrc

4.创建资源文件名Resources.qrc

5.把资源文件加入到你的工程中

6.并在CMakeLists.txt加入Resources.qrc并保存（control + s),这时左侧项目工程会自动生成Resources.qrs

7.左侧右键点击Resources.qrs文件添加前缀

8.添加图片，关联到此前缀来：
右键·Resources.qrc > Open in Editor > 选中>Add Files > 从打开的文件选择器中选择icon1.png,icon2.png,padfsplit.ico,se_center.png



9.添加图片，复制图片路径

在代码中加入图片路径

二、代码
