• buttonAlert ?-w win? ?-title str? ?-index? ?--? text button ?button...?
Create a dialog with an arbitrary number of buttons. One must specify at least one button. The
alert's dimensions are calculated automatically depending on the size of
the text argument.
The -title option specifies a string
displayed in boldface.
If the -w option is specified, the alert is displayed in a
sheet window attached to the window designated by the win argument.
Otherwise, the alert is displayed as a modal dialog.
By default, the command returns the name of the selected button but,
if the -index option is specified, it
returns the button's index (starting at 0 for the rightmost button).
