- =head1 NAME
-
- Tk::Dialog - Create modal dialog and wait for a response.
-
- =for pm Tk/Dialog.pm
-
- =for category Popups and Dialogs
-
- =head1 SYNOPSIS
-
- S< >I<$dialog> = I<$parent>-E<gt>B<Dialog>(I<-option> =E<gt> I<value>, ... );
-
- =head1 DESCRIPTION
-
- This procedure is part of the Tk script library - its arguments
- describe a dialog box. After creating a dialog box, B<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 text string of the selected Button.
-
- While waiting for the user to respond, B<Dialog> sets a local
- grab. This prevents the user from interacting with the application
- in any way except to invoke the dialog box. See the B<Show()> method.
-
- =head1 OPTIONS
-
- The following option/value pairs are supported:
-
- =over 4
-
- =item B<-title>
-
- Text to appear in the window manager's title bar for the dialog.
-
- =item B<-text>
-
- Message to appear in the top portion of the Dialog.
-
- =item B<-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.
-
- =item B<-default_button>
-
- Text label string of the Button that displays the default ring.
-
- =item B<-buttons>
-
- A reference to a list of Button label strings. Each I<string>
- specifies text to display in a Button, in order from left to right.
-
- =back
-
- =head1 METHODS
-
- =over 4
-
- =item I<$answer> = $dialog-E<gt>B<Show(>?-global?B<)>;
-
- This method displays the Dialog, waits for the user's response, and stores
- the text string of the selected Button in I<$answer>. If I<-global> is
- specified a global (rather than local) grab is performed.
-
- The actual Dialog is shown using the B<Popup> method. Any other
- options supplied to B<Show> are passed to B<Popup>, and can be used to
- position the Dialog on the screen. Please read Tk::Popup for details.

-
- =head1 ADVERTISED WIDGETS
-
- Because Tk::Dialog is a subclass of Tk::DialogBox it inherits all the
- advertised subwidgets of its superclass: e.g. "B_button-text", where
- 'button-text' is a Button's -text value. Additionally, Tk::Dialog
- advertises:
-
- =over 4
-
- =item B<message>
-
- The dialog's Label widget containing the message text.
-
- =item B<bitmap>
-
- The dialog's Label widget containing the bitmap image.
