Answer 1

If you are talking about how to do this windows, you can do:

this->setWindowIcon(QIcon(":myiconfile.png"));

You will have to add the file in your resources.

Answer 2

You can set the window icon on your widget as per documentation with the following property:

windowIcon : QIcon

This property holds the widget's icon.

This property only makes sense for windows. If no icon has been set, windowIcon() returns the application icon (QApplication::windowIcon()).

So, your code would look like something like this:

myWidget->setWindowIcon("/path/to/your/icon/file");

The icon file path can be relative and absolute as well as one coming from the resource system. The easiest way to test it quickly is just to use the absolute path, but if you plan to ship assets with your application to be self-contained, then you can use resource file with the resource system .
