前言

以前用的Qt5.15.2之前的版本，QtCreator默認的工程文件是*.pro，現在用5.15.2創(chuàng)建工程默認的工程文件是CMameList.txt,當然在創(chuàng)建項目時，仍然可以使用pro工程文件用QtCreator打開CMakeList.txt
以前用習慣了pro文件，現在改成CMakeList很不習慣，現在我們在CMakeList.txt中加入資源文件

一、加入圖片資源

1.首先，在Qt項目里創(chuàng)建一個目錄image，然后將圖片資源放image目錄中

2.在Qt creator中創(chuàng)建resource file
鼠標右鍵項目listWidgetSplitter> Add New… > Qt > Qt Resource File > 輸入文件名Resources，->next

3.新建資源文件.qrc

4.創(chuàng)建資源文件名Resources.qrc

5.把資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),這時左側項目工程會自動生成Resources.qrs

7.左側右鍵點擊Resources.qrs文件添加前綴

8.添加圖片，關聯(lián)到此前綴來：
右鍵·Resources.qrc > Open in Editor > 選中>Add Files > 從打開的文件選擇器中選擇icon1.png,icon2.png,padfsplit.ico,se_center.png



9.添加圖片，復制圖片路徑

在代碼中加入圖片路徑

二、代碼

    // _popMenuLeft->exec(QCursor::pos());
    _popMenuLeft->exec(_listWgtLeft->mapToGlobal(pos));
}

代碼調用

```cpp
#include "MainWindow.h"
#include "listControl.h"
#include <QApplication>
#include <QTextCodec>
#include <QDebug>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    // MainWindow w;
    // w.show();

    a.setFont(QFont("Microsoft Yahei", 9));
    QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8"));
    qDebug() << "中文調試信息";

    QFont font("ZYSong18030" , 10);
    a.setFont(font);

    listControl* contrl = new listControl;
    contrl->show();

    return a.exec();
}
