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 having unique values that are assigned to each individual option that is specified.

“Checkbutton”:

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

  • • “Checkbutton” widget enables the user to read and select 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, thereby making the buttons mutually exclusive of each other.
