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.
