You can add an icon to your app by saving an image file in your project folder.
To add an image to use as the app icon:
Download the following image and save it as icon.png in the QtApp project folder:
You can obtain this image from this location on the Qt website:
You can also use any other appropriately sized image file as an icon. We suggest the Qt logo image only for simplicity.
Note:
The icon gets packaged into the app's BAR file—it shouldn't be compiled into
resources.qrc.
