Displaying a confirmation dialog

The tk_dialog command displays a modal message window and awaits the user's response. The value returned provides the index of the button selected: 0 for the leftmost; with the value increasing by 1 for each additional button. If the dialog is destroyed prior to the user making a selection, the return value is -1. All arguments must be provided.

The syntax is as follows:

tk_dialog window title text bitmap default string…

Option	Interpretation
window	Name to assign to the dialog (for example confirmDialog).
title	Sets the text to be displayed in the dialog title bar.
text	Sets the message to be displayed
bitmap	Sets the bitmap (icon) to be displayed in the top of the dialog to the left of the text. If an empty string is passed no bitmap will be displayed.
default	Designates which button is default. This may have an effect on the visual appearance of the buttons and can also be tied to the <return> key.
string	Sets the text to display...
