NAME

       Tk::waitVariableX - a waitVariable with extensions.

SYNOPSIS

	use Tk::waitVariableX;

	$splash->waitVariableX( [$millis, $destroy_splashscreen], $v1, $v2} );

DESCRIPTION

       This subroutine waits for a list of variables, with a timeout - the subroutine returns when one of the variables changes value or the time-
       out expires, whichever occurs first.

       Although the millisecond parameter is required, it may be zero, which effects no timeout. The milliscond paramter may also be an array of
       two elements, the first the millisecond value, and the second a normal Per/Tk callback. The callback is invoked just before waitVariableX
       returns.

       Callback format is patterned after the Perl/Tk scheme: supply either a code reference, or, supply an array reference and pass the callback
       code reference in the first element of the array, followed by callback arguments.

NAME

       Tk::Splashscreen - display a Splashscreen during program initialization.

SYNOPSIS

	$splash = $parent->Splashscreen(-opt => val, ... );

DESCRIPTION

       For programs that require large load times, it's a common practice to display a Splashscreen that occupies the user's attention.  This
       Toplevel mega widget provides all the display, destroy and timing events.  All you do it create the Splashscreen mega widget, populate it
       as you see fit, then invoke Splash() to display it and Destroy() to tear it down.

       Important note: be sure to sprinkle update() calls throughout your initialization code so that any Splashscreen events are handled.  Remem-
       ber, the screen may be animated, or the user may be simply moving the Splashscreen about.

OPTIONS

       The following option/value pairs are supported:

       -milliseconds
	   The minimum number of milliseconds the Splashscreen should remain on the screen.  Default is 0, which means that the Splashscreen is
	   destroyed as soon as Destroy() is called.  Otherwise, Destroy() waits for the specified time interval to elapse before destroying the
	   Splashscreen.

METHODS

       $splash->Splash([milliseconds]);

       If milliseconds is specified, it's the minimum number of milliseconds the Splashscreen should remain on the screen.  This value takes
       precedence over that specified on the Splashscreen constructor call.

       $splash->Destroy([milliseconds]);

       If milliseconds is specified, it's the minimum number of milliseconds the Splashscreen should remain on the screen.  This value takes
       precedence over that specified on the Splash() call, which takes precedence over that specified during Splashscreen construction.

BINDINGS

       <ButtonPress-3>

       Notifies the Splashscreen to set a mark for an impending move.

       <ButtonRelease-3>

       Moves the Splashscreen from the mark to the cursor's current position.

ADVERTISED WIDGETS

       Component subwidgets can be accessed via the Subwidget method.  This mega widget has no advertised subwidgets. Instead, treat the widget
       reference as a Toplevel and populate it as desired.

EXAMPLE

	$splash = $mw->Splashscreen;

	... populate the Splashscreen toplevel as desired ...

	$splash->Splash(4000);

	... program initialization ...

	$splash->Destroy;
