week of Nov 28

event-driven programming

Here’s some code from booksite, section 3.6:

Sample programs Graffiti.java, Squares.java Paint.java, Point.java

Library classes that aren’t in StdLib: Draw.java, DrawListener.java

week of Dec 5

wrap-up and review

EXAM Thurs Dec 8 exam in E222 from 2:00–2:50pm; Fri exam in lecture

Here is the homework assignment: MandelApp.pdf

Here are MousablePicture.java, MousablePictureListener.java, which augment the Picture API to include mouse events.

Here is a program which displays the Mandelbrot set in a MousablePicture: MandelMouse3.java and MandelMouse3Listen.java. It shows how a listener can call a method of the main application. Compared with MandelMouse2 which I distributed before, the only change is to make it more clear how coordinates in the picture are transformed (by method transform()) to coordinates in the Complex plane.

Here is a color version of the image, from the booksite: Mandelbrot.java.
