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, assuming you are using qmake to generate your makefiles, you only need to add a single line to your .PRo project file: RC_ICONS = myappico.icoFinally, regenerate your makefile and your application. The .exe file will now be represented by your icon in Explorer.However, if you already have an .rc file, for example, with the name myapp.rc, which you want to reuse, the following two steps will be required. First, put a single line of text to the myapp.rc file: IDI_ICON1 ICON DISCARDABLE "myappico.ico"Then, add this line to your myapp.pro file: RC_FILE = myapp.rcIf you do not use qmake, the necessary steps are: first, create an .rc file and run the rc or windres program on the .rc file, then link your application with the resulting .res file.新聞熱點
