- =head1 NAME
-
- Tk::DialogBox - create and manipulate a dialog screen.
-
- =for pm Tixish/DialogBox.pm
-
- =for category Tix Extensions
-
- =head1 SYNOPSIS
-
- use Tk::DialogBox
- ...
- $d = $top->DialogBox(-title => "Title", -buttons => ["OK", "Cancel"]);
- $w = $d->add(Widget, args);
- ...
- $button = $d->Show;
-
- =head1 DESCRIPTION
-
- B<DialogBox> is very similar to B<Dialog> except that it allows
- any widget in the top frame. B<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
- B<add()> method. The non-standard options recognized by
- B<DialogBox> are as follows:
-
- =over 4
-
- =item B<-title>
-
- Specify the title of the dialog box. If this is not set, then the
- name of the program is used.
-
- =item B<-buttons>
-
- The buttons 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 buttons, no buttons will be displayed.
-
- =item B<-default_button>
-
- Specifies the default button that is considered invoked when user
- presses <Return> on the dialog box. This button is highlighted. If
- no default button is specified, then the first element of the
- array whose reference is passed to the B<-buttons> option is used
- as the default.

-
- =head1 METHODS
-
- B<DialogBox> supports only two methods as of now:
-
- =over 4
-
- =item B<add(>I<widget>, I<options>B<)>
-
- Add the widget indicated by I<widget>. I<Widget> can be the name
- of any Tk widget (standard or contributed). I<Options> are the
- options that the widget accepts. The widget is advertized as a
- subwidget of B<DialogBox>.
-
- =item B<Show(>I<grab>B<)>
-
- Display the dialog box, until user invokes one of the buttons in
- the bottom frame. If the grab type is specified in I<grab>, then
- B<Show> uses that grab; otherwise it uses a local grab. Returns
- the name of the button invoked.
-
- =back
-
- =head1 BUGS
-
- There is no way of removing a widget once it has been added to the
- top frame.
-
- 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 e.g. widgets to the left,
- buttons to the right instead of widgets on the top and buttons on
- the bottom always.
