I am working with Qt to create a front-end for my application. Now I wanted to set an customized ICON for my application executable. I am using Qt 6.4. Already I create an resource file which it has .qrc format. Then I added my icon to that resource file. Now I wanted to know how can I set that icon file as executable icon. Is that possible somebody explain how can I set an customized icon for my application? Also I wanted to know how can I modify CMake to instruct compiler which executable should run with administrator privilege. Thank you.

Solution depends on your platform (Windows, mac, Linux) as well as your configuration tool (CMake, qmake).

Have a look at Qt documentation: https://doc.qt.io/qt-6/appicon.html. It tells what to do.

To achieve that, in my side, I'm doing 2 things :

1.

    QApplication a(argc, argv);
    a.setWindowIcon(QIcon(":/img/AppIcon.png"));

2. Create a resource.rc file with this content (have to possess a .ico version of the image)

IDI_ICON1               ICON    DISCARDABLE     "img/AppIcon.ico"

and declare in .pro

RC_FILE  = \
    resource.rc
