Description
Inheritance
1. Download the InheritanceDemo.zip file and study the code in that project.
2. In it, there is a superclass called Shape, and several children classes, including Circle, Rect, and
Point.
3. There is a new class definition for a TextBox starting on line 96, but it has not been completed. Your
task is to complete it.
4. A TextBox object should be just a string positioned at a particular point on the screen. Your
constructor should allow me to specify the string in the TextBox, the position of it, the font, and the
color.
5. There is a function called renderText, which demonstrates how to produce text on the screen.
Experiment with this function a lot so you can learn how it works.
6. There is not a large font selection. Valid font values are:
GLUT_BITMAP_TIMES_ROMAN_24
GLUT_BITMAP_TIMES_ROMAN_10
GLUT_BITMAP_HELVETICA_18
GLUT_BITMAP_HELVETICA_12
GLUT_BITMAP_HELVETICA_10
GLUT_BITMAP_8_BY_13
GLUT_BITMAP_9_BY_15
7. Your TextBox object should be designed in such a way that when we uncomment line 295, it should
just work, without the need for any extra steps.
