NAME

Tk::Dialog - Perl/Tk Dialog widget

SYNOPSIS

require Tk::Dialog;

$DialogRef = $widget->Dialog(
    -title          => $title,
    -text           => $text,
    -bitmap         => $bitmap,
    -default_button => $default_button,
    -buttons        => [@button_labels],
);

$selected = $DialogRef->Show(?-global?);

DESCRIPTION

This is an OO implementation of `tk_dialog'. First, create all your Dialog objects during program initialization. When it's time to use a dialog, invoke the Show method on a dialog object; the method then displays the dialog, waits for a button to be invoked, and returns the text label of the selected button.

A Dialog object essentially consists of two subwidgets: a Label widget for the bitmap and a Label wigdet for the text of the dialog. If required, you can invoke the `configure' method to change any characteristic of these subwidgets.

Because a Dialog object is a Toplevel widget all the 'composite' base class methods are available to you.

Advertised widgets: bitmap, message.

1)

Call the constructor to create the dialog object, which in turn returns a blessed reference to the new composite widget:

require Tk::Dialog;

$DialogRef = $widget->Dialog(
    -title          => $title,
    -text           => $text,
    -bitmap         => $bitmap,
    -default_button => $default_button,
    -buttons        => [@button_labels],
);

• mw

  a widget reference, usually the result of a MainWindow->new call.

• title

  Title to display in the dialog's decorative frame.

• text

  Message to display in the dialog widget.

• bitmap

  Bitmap to display in the dialog.

• default_button

  Text label of the button that is to display the default ring (''signifies no default button).

• button_labels

  A reference to a list of one or more strings to display in buttons across the bottom of the dialog.

2)

Invoke the Show method on a dialog object

$button_label = $DialogRef->Show;

This returns the text label of the selected button.

(Note: you can request a global grab by passing the string -global to the Show method.)
