NAME
tk_dialog - Create modal dialog and wait for response
SYNOPSIS
tk_dialog window title text bitmap default string string ...
_________________________________________________________________
DESCRIPTION
This procedure is part of the Tk script library. Its
arguments describe a dialog box:
window
Name of top-level window to use for dialog. Any
existing window by this name is destroyed.
title
Text to appear in the window manager's title bar for
the dialog.
text Message to appear in the top portion of the dialog box.
bitmap
If non-empty, specifies a bitmap to display in the top
portion of the dialog, to the left of the text. If
this is an empty string then no bitmap is displayed in
the dialog.
default
If this is an integer greater than or equal to zero,
then it gives the index of the button that is to be the
default button for the dialog (0 for the leftmost
button, and so on). If less than zero or an empty
string then there won't be any default button.
string
There will be one button for each of these arguments.
Each string specifies text to display in a button, in
order from left to right.
After creating a dialog box, tk_dialog waits for the user to
select one of the buttons either by clicking on the button
with the mouse or by typing return to invoke the default
button (if any). Then it returns the index of the selected
button: 0 for the leftmost button, 1 for the button next to
it, and so on. If the dialog's window is destroyed before
the user selects one of the buttons, then -1 is returned.
While waiting for the user to respond, tk_dialog sets a
local grab. This prevents the user from interacting with

the application in any way except to invoke the dialog box.
