Computer Graphics Mickey Mouse In this labwork are asked to write a GUI application using AWT. It is highly advised that you build your work and knowledge upon the last labwork. You can watch the small video demo on WebOnline to get a better understanding. In additional to what we did in Lab3 you are going to; • Add a control panel. • Add two buttons to the panel called "Smaller" and "Bigger". • Menubar of this program should have an item called "Set Default"which will reset the values of x, y, dx and dy to the values they had initially. • Modify the action listener according to the buttons and menu item. • Set the title to "Mickey" in the constructor and add your WindowListener. • Modify your paint method to draw 3 ovals which makes up Mickey Mouse silhouette. Smaller ovals have half the radius of the big oval. • The center of the circle is determined by the variables x and y, and the radius of circles should be dependent on dx and dy (which are equal since we are using circles). •…
