DialogBox(3) perl/Tk Documentation DialogBox(3)NAMETk::DialogBox - create and manipulate a dialog screen.
SYNOPSIS
use Tk::DialogBox
...
$d = $top->DialogBox(-title => "Title", -buttons => ["OK", "Cancel"]);
$w = $d->add(Widget, args);
...
$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 add() method. The non-standard
options recognized by DialogBox are as follows:
-title
Specify the title of the dialog box. If this is not
set, then the name of the program is used.
-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.
-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 -buttons option is used as
the default.
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.
Show(grab)
Display the dialog box, until user invokes one of the
buttons in the bottom frame. If the grab type is
specified in grab, then Show uses that grab; otherwise
it uses a local grab. Returns the name of the button

invoked.
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.
