Name
	Tie::Wx::Widget - get&set main value of a Wx widget with less syntax and more magic

USAGE

	use Tie::Wx::Widget;

	tie $tiedwidget, Tie::Wx::Widget, $widget;

	$tiedwidget = 7;       # instead of $widgetref->SetValue(7);

	say $tiedwidget;       # instead of say $widgetref->GetValue;

	untie $tiedwidget;     # now $tiedwidget is a normal scalar again (not required)


CALLBACKS

Often are the widget values couples with each other. For instance in
App::Spirograph is a slider which max value is dependent on the value
of another slider. Once you know this, why keep track of it and change
the range of the second slider by hand any given time?

	tie $tslider, Tie::Wx::Widget, $slider, sub { $subslider->SetRange(1, $_) };

$_ holds the assigned value.

The complete parameter list is is:

	tie $tw, Tie::Wx::Widget, $widget, [&$do_when_assign, &$do_when_retrieve];


WARNINGS

Your program will C<die>, if you don't provide a proper Wx widget,
that has a GetValue and SetValue method, or the callbacks are no coderef.
Unless you init with:

	use Tie::Wx::Widget 'warn_mode';

or do later:

	Tie::Wx::Widget::warn_mode();

Then will be called C<warn> instead of C<die>. 
But you can switch anytime back with:

	Tie::Wx::Widget::die_mode();

Wich has only effect for all variables tied afterwards.
Because if the Wx ref is not good, there will be no tying anyway.


INTERNALS

	# how to get a reference to the Tie::Wx::Widget object ?
	$tieobject = tie $tiedwidget, Tie::Wx::Widget, $widget;
	$tieobject = tied $tiedwidget;

	# now you even can:
	$tieobject->FETCH()
	# aka:
	$tieobject->{'widget'}->GetValue;
	# or do any other method on the wx object
	$tieobject->{'w'}->Show(0);
	# works too  (hides the widget)
	$tieobject->STORE(7);

	# doesn't do anything
	$tieobject->DESTROY()
