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.
Remember, the screen may be animated, or the user may be simply moving
the Splashscreen about.
The following option/value pairs are supported:
Destroy() is called. Otherwise, Destroy() waits
for the specified time interval to elapse before destroying the
Splashscreen.
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.
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.
Notifies the Splashscreen to set a mark for an impending move.
Moves the Splashscreen from the mark to the cursor's current position.
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.
$splash = $mw->Splashscreen;
... populate the Splashscreen toplevel as desired ...
$splash->Splash(4000);
... program initialization ...
$splash->Destroy;
