NAME

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


SYNOPSIS

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


DESCRIPTION

       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 aadddd(()) method.


OPTIONS

       The options recognized by DialogBox are as follows:

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

       -buttons
           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.

       -default_button
           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
           default.

       -cancel_button
           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
           DialogBox.

       -command
           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.

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

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


METHODS

       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. aadddd(())
           does not automatically ppaacckk(()) or ggrriidd(()) widget into the DialogBox.

       Show(?-global?)
           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
           details.

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


ADVERTISED WIDGETS

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

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

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


BUGS

       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
       widgets.

       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.
