Cannot set the application icon

  • Hello.
    I come here with, what seems like, a simple problem. I want to set the applicacion icon (not window icon) so that the .exe has an icon in the windows explorer. I read "here": how to do it, but none of both versions are working.

    @RC_ICONS = myappico.ico@
    This one does not even compile. It seems Qt does not recognize RC_ICONS as it is not highlighted in purple. (I have Qt 5). When compiling I get
    @[release/projectname_resource_res.o]Error 1@

    @IDI_ICON1 ICON DISCARDABLE "myappico.ico"@
    This one does compile, but the .exe lacks the icon.

    The icon is in .ico format and is in the same folder as the project.

    Can you show the exact error you are getting ?

    What size/resolution are you using for your ico file ?

    Which version of Windows are you running on ?

  • You need to both:

    • create an .rc file (looking like your #2)
    • reference this rc file from your .pro file like this: @win32:RC_FILE = myapp.rc@
