,通过搜索Qt Assistant,发现有如下说明:

Setting the Application Icon on Windows


First, create an ICO format bitmap file that contains the icon image. This can be done with e.g. Microsoft Visual C++: Select File|New, then select the File tab in the dialog that appears, and choose Icon. (Note that you do not need to load your application into Visual C++; here we are only using the icon editor.)

Store the ICO file in your application's source code directory, for example, with the name myappico.ico. Then, create a text file called, say, myapp.rc in which you put a single line of text:

 IDI_ICON1               ICON    DISCARDABLE     "myappico.ico"Finally, assuming you are using qmake to generate your makefiles, add this line to your myapp.pro file:

 RC_FILE = myapp.rcRegenerate your makefile and your application. The .exe file will now be represented with your icon in Explorer.

If you do not use qmake, the necessary steps are: first, run the rc program on the .rc file, then link your application with the resulting .res file.

那么做法就清楚了:

第一步,准备个ICO图标。

例如:myApp.ico 用任何的文本编辑器新建个文件

里面写上一行:
IDI_ICON1           ICON DISCARDABLE "myApp.ico"
 

第二步,保存改名为 myApp.rc并把它和你的图标myApp.ico一起放置到你的Qt工程的目录里面。

第三步,用文本编辑器打开你的Qt工程文件(如 myApp.pro ),在里面的最后面新添一行:
RC_FILE = myApp.rc 

第四步,在程序中添加如下代码:

//app是程序中唯一的QApplication对象

app.setWindowIcon(QIcon("myApp.ico")); 

注意:如果你的myApp.rc和你的图标myApp.ico不是在你的Qt工程目录里面,那么最后一句的代码中请指明图标文件的路径。
