Creating the application icon

We created our sample window, and now we go on to customize it with some features fitting our needs. For each customization, we add a new function under the SampleWindow class in the previous program to define its properties, and we call this our main function to apply these properties on the sample window. In this section, we define an icon to be set on the window that we created. An icon is a small image that is created to visually emphasize the purpose of the program. It is displayed in the top-left corner of the application window. The same is also displayed in the taskbar when the application is minimized. As a prerequisite for this program, you may need an icon image with dimensions similar to the image that is used here (72 X 72). You can create your own image or download it from the book's website if you wish to use the one used in this program:
