DialogBox(3)	      User Contributed Perl Documentation	  DialogBox(3)

       Tk::DialogBox - create and manipulate a dialog screen.

	   use Tk::DialogBox
	   $d =	$top->DialogBox(-title => "Title", -buttons => ["OK", "Cancel"]);
	   $w =	$d->add(Widget,	args)->pack;
	   $button = $d->Show;

       DialogBox is very similar to Dialog except that it allows any widget in
       the top Frame. DialogBox	creates	two Frames, top	and bottom. The	bottom
       Frame shows all the specified Buttons, lined up from left to right. The
       top Frame acts as a container for all other widgets that	can be added
       with the	add() method.

       The options recognized by DialogBox are as follows:

	   Specify the title of	the DialogBox. If this is not set, then	the
	   name	of the program is used.

	   The button names to display in the bottom Frame. This is a
	   reference to	an array of strings containing the text	to put on each
	   Button. There is no default value for this. If you do not specify
	   any button names, no	Buttons	are displayed.

	   Specifies the default Button	that is	considered invoked when	user
	   presses <Return> on the DialogBox. This Button is highlighted. If
	   no default Button is	specified, then	the first element of the array
	   whose reference is passed to	the -buttons option is used as the

	   Specifies the Button	that is	considered invoked when	the user
	   closes the DialogBox	using the window manager's close button. If
	   the -cancel_button option is	not given, and if there's only one
	   button configured, then this	button is also used as the cancel
	   button.  Otherwise no button	is considered as the cancel button; in
	   such	a case Show just returns "undef" when the user closes the

	   A callback which is executed	after invoking an action to close the
	   DialogBox, but before restoring focus and grab information. The
	   selected button is passed as	the first argument.

	   Specify the widget to receive the initial focus after popping up
	   the DialogBox. By default the -default_button widget	receives the
	   initial focus.

	   A callback which is executed	before displaying the DialogBox	and
	   waiting for user input. The DialogBox itself	is passed as the first

       DialogBox supports only two methods as of now:

       add(widget, options)
	   Add the widget indicated by widget. Widget can be the name of any
	   Tk widget (standard or contributed).	options	are the	options	that
	   the widget accepts. The widget is advertized	as a subwidget of
	   DialogBox. The name of widget is lower-cased	and used as the
	   advertised name. If multiple	instances of widget are	created	in the
	   DialogBox, then only	the last one gets the advertised name. add()
	   does	not automatically pack() or grid() widget into the DialogBox.

	   Displays the	Dialog until the user invokes one of the Buttons in
	   the bottom Frame. If	the grab type -global is specified, then Show
	   uses	that grab; otherwise it	defaults to a local grab. Returns the
	   name	of the Button invoked.

	   The actual Dialog is	shown using the	Popup method. Any other
	   options supplied to Show are	passed to Popup, and can be used to
	   position the	Dialog on the screen. Please read Tk::Popup for

	   Close the dialogbox,	by emulating a click on	the default button.

       top The subwidget reference to the top half of the DialogBox widget,
	   the Frame containing	widgets	added by the add method.

	   The subwidget reference to the bottom half of the DialogBox widget,
	   the Frame containing	the Button widgets.

	   Individual subwidget	references to the Buttons in the DialogBox
	   widget. The subwidget name is the string B_ concatenated with the
	   Button's -text value.

       There is	no way of removing a widget once it has	been added to the top
       Frame, unless you access	the top	subwidget and go through the child

       There is	no control over	the appearance of the Buttons in the bottom
       Frame nor is there any way to control the placement of the two Frames
       with respect to each other.
