Foil 142 Changing Graphics: repaint method

From Basic Lectures on Java Language Applets Graphics Networking Trip to China and Icase Tutorial -- July 12-28 and June 10-13 96. by Geoffrey C. Fox * See also color IMAGE
Most applets and windows applications want to change what is drawn on the screen over its lifetime. This can be a sequenced animation, response to user input or mouse events, and so on.
Whenever you want to redraw the screen, call
  • void repaint();
Repaint gets the graphics context and creates a thread to call update, which calls your paint function. So all your drawing changes are also put into paint.
