Source code for Graphics Project

Project files:

The project contains the following files, which can be viewed as highlighted source code.

• Package coordinatechanges
  • File DemoFrame.java: This class implements a window which contains a DemoPanel. The window has a menu bar and a status bar. Click here to run it.
  • File DemoPanel.java: This is a simple panel (part of a window) which dispays some mathematical graphics. It converts objects from math to screen coordinates before dispaying them using the TransformManager class.
  • File TransformChangedListener.java: This is an interface that allows a TransformManager to notify a panel when the coordinate transformation has changed.
  • File TransformManager.java: Manages a coordinate change from math-coordinates to screen coordinates. The class guarantees that a certain rectangle will be displayed.
• Package drawsomething
  • File Complex.java: A complex number class.
  • File DrawSomething.java: Modifies the DrawingDemo class to draw a logarithmic spiral using the Complex number class.
• Package justdrawing
  • File AffineTransformDemo.java: This is a simple demonstration of the use of an AffineTransform object to transform shapes before drawing. The class was based on the DrawingDemo class.
  • File DrawingDemo.java: A simple program which draws some graphics in a window. Click here to run it using Java Web Start.
• Package layers
  • File CircleLayer.java: This is a small modification of CircleLayer, which handles squares instead of circles.
  • File LayerDemoFrame.java: An executable program demonstrating the use of Layers. The program creates a window with two layers, which enable the user to create disks and squares and move them around.
  • File LayeredPanel.java.
  • File Layer.java: An interface representing a "Layer" of graphics.
  • File SquareLayer.java: An implementation of the Layer interface. The code was mostly taken out of InteractionDemo.java.
• Package mouseinteraction
  • File InteractionDemo.java: A program which allows the user to plot some disks and move them around by dragging. Click here to run it.
• Package simplermouseinteraction
  • File Drawing.java: Simple drawing program written at ICERM. This program was based off of the SimpleInteractionDemo class.
  • File SimpleInteractionDemo.java: A program which allows the user to manipulate a disk in the plane. Click here to run it.
