Chapter 13, Problem 9SA
Program Plan Intro

“IntVar” object:

A class named “IntVar” can be used along with the “tkinter” radiobutton widget.

  • • The “IntVar” object can be associated with a group of check buttons with unique values that are assigned to each individual option that is specified.

“Checkbutton”:

The “Checkbuttons” are used to select any or the entire buttons that are displayed in the groups so that “checkbutton” is not mutually an exclusive selection.

  • • “Checkbutton” widget contains the user to read and select a two-way choice.
  • • When the “Checkbutton” is selected, the associated “IntVar” object will hold the value “1”; if it is not selected, then the associated “IntVar” object will hold the value “0”.
  • • The “Checkbutton” can be implemented to multiple choice input widgets by assigning each button a variable of its own process.
  • • The “Checkbutton” is very similar to the “radiobutton”; when one choice is selected, the others in the group can be deselected, and it can make the buttons be mutually exclusive from each other.

It is uncertain what the SizeMode property of the Picture Box control defaults to.
Dice Simulator Create an application that simulates rolling a pair of dice. When the user clicks a button, the application should generate two random numbers, each in the range of 1 through 6, to represent the value of the dice. Use PictureBox controls to display the dice. (In the Student Sample Programs, in the Chap05 folder, you will find six images named Die1.bmp, Die2.bmp, Die3.bmp, Die4.bmp, Die5.bmp, and Die6.bmp that you can use in the PictureBoxes.)
