Splashscreen(3pm) perl/Tk Documentation Splashscreen(3pm)
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;
