Agenda

• Announcements
• Lecture 2 assignment recap
• Checking if a graphical object contains a point
• Custom colors
• Dragging objects
• In-class Exercise 3 - (10 lecture assignment points) due before the end of class.

  Write a program ColorScribble.java that combines some of the features of our recent examples into a "scribble" program that allows selection of colors.

  It should present a set of color-selection "buttons" (really just FilledRects with FramedRects for borders) that, when clicked, select a color to be used to draw scribbles until the next time a color selection button is clicked.

  A sample solution:

  ColorScribble

  Please submit only the file ColorScribble.java in Submission Box under "InClass3" before you leave class.

• Lab 2: Laundry Sorter out - a written design is required for the start of class next time.

No New Lecture Assignment

Just finish up the In-Class exercise.

Also, don't forget to do your written design for the Laundry Sorter lab before class on Thursday.
