Qt应用程序的图标

 

程序设计完成了，如何修改exe文件的图标呢，总不能用默认的白板吧，搜来搜去，终于在Qt助手中搜到答案了，粘贴到这里备忘。

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.rc

Regenerate 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.
