Properties of Python Tkinter Checkbutton.

1. activebackground: Background color when the checkbutton is under the cursor.   2. activeforeground: Foreground color when the checkbutton is under the cursor.   3. bg: The normal background color displayed behind the label and indicator.   4. bitmap: To display a monochrome image on a button.   5. bd: The size of the border around the indicator. Default is 2 pixels.   6. command: A procedure to be called every time the user changes the state of this checkbutton.   7. cursor: If you set this option to a cursor name (arrow, dot, etc.), the mouse cursor will change to that pattern when it is over the checkbutton.   8. disabledforeground: The foreground color is used to render the text of a disabled checkbutton. The default is a stippled version of the default foreground color.   9. font: The font used for the text.   10. fg: The color used to render the text.   11. height: The number of lines of text on the checkbutton. Default is 1.   12. highlightcolor: The color of the focus is highlighted when the checkbutton has the focus.   13. image: To display a graphic image on the button.   14. justify: If the text contains multiple lines, this option controls how the text is justified: CENTER, LEFT, or RIGHT.   15. offvalue: Normally, a checkbutton's associated control variable will be set to 0 when it is cleared (off). You can supply an alternate value for the off-state by setting offvalue to that value.   16. onvalue: Normally, a checkbutton's associated control variable will be set to 1 when it is set (on). You can supply an alternate value for the on-state by setting onvalue to that value.   17. padx: How much space to leave to the left and right of the checkbutton and text. Default is 1 pixel.   18. pady: How much space to leave above and below the checkbutton and text. Default is 1 pixel.   19. relief: With the default value, relief=FLAT, the checkbutton does not stand out from its background. You may set this option to any of the other styles   20. selectcolor: The color of the checkbutton when it is set. Default is selectcolor="red".   21. selectimage: If you set this option to an image, that image will appear in the checkbutton when it is set.   22. state: The default is state=NORMAL, but you can use state=DISABLED to gray out the control and make it unresponsive. If the cursor is currently over the checkbutton, the state is ACTIVE.   23. text: The label is displayed next to the checkbutton. Use newlines ("\n") to display multiple lines of text.   24. underline: With the default value of -1, none of the characters of the text label are underlined. Set this option to the index of a character in the text (counting from zero) to underline that character.   25. variable: The control variable that tracks the current state of the checkbutton. Normally this variable is an IntVar, and 0 means cleared and 1 means set, but see the offvalue and onvalue options above.   26. width: The default width of a checkbutton is determined by the size of the displayed image or text. You can set this option to a number of characters and the checkbutton will always have room for that many characters.   27. Wraplength: Normally, lines are not wrapped. You can set this option to a number of characters and all lines will be broken into pieces no longer than that number.

1. deselect(): Clears (turns off) the checkbutton.   2. flash(): Flashes the checkbutton a few times between its active and normal colors, but leaves it the way it started.   3. invoke(): You can call this method to get the same actions that would occur if the user clicked on the checkbutton to change its state.   4. select(): Sets (turns on) the checkbutton.   5. toggle(): Clears the checkbutton if set, sets it if cleared.
