=head2 action or undef = $widget-E<gt>B<get_action> 

Since: gtk+ 2.10

=head2 boolean = $widget-E<gt>B<activate> 

This function works by emitting an action signal nominated by the various
widget subclasses.  The signal is normally called C<activate>, but it
doesn't have to be.

Currently if you make a widget subclass in Perl there's no way to
nominate a signal to be emitted by C<< $widget->activate >>.  A signal
merely named C<activate> is not automatically hooked up.

=head2 rectangle = $widget-E<gt>B<allocation> 

Return the current allocated size and position of $widget within its
parent widget.  The allocated size is not necessarily the same as the
requested size.

The returned rect object points into $widget and can only be used as
long as $widget exists.

=head2 requisition = $widget-E<gt>B<get_child_requisition> 

This function is only for use in widget implementations.  Obtains
C<< $widget->requisition >>, unless someone has forced a particular geometry
on the widget (e.g., with C<set_usize()>, in which case it returns that
geometry instead of the widget's requisition.

This function differs from
L<size_request()|requisition = $widget-E<gt>size_request ()>
in that it retrieves the last size request value from
C<< $widget->requisition >>,
while C<size_request()> actually calls the C<size_request> virtual method
(that is, emits the "size-request" signal) on the I<$widget> to compute
the size request and fill in C<< $widget->requisition >>, and only then
returns C<< $widget->requisition >>.

Because this function does not call the C<size_request> method, it can only
be used when you know that C<< $widget->requisition >> is up-to-date.  In
general, only container implementations have this information; applications
should use C<size_request ()>.

You most likely don't want to use any of these functions; synthesizing events
is rarely needed. Consider asking on the mailing list for better ways to
achieve your goals. For example, use Gtk2::Gdk::invalidate_rect or
Gtk2::Widget::queue_draw instead of making up expose events.

This function works by emitting a setter signal nominated by the
various widget types which have "native" scrolling.  The signal is
normally called C<set-scroll-adjustments>, but it doesn't have to be.

If you make a widget subclass in Perl and create a signal in it called
C<set-scroll-adjustments> taking two Gtk2::Adjustment parameters then
the subclassing automatically hooks that up to be emitted by
C<< $widget->set_scroll_adjustments >>.  (Your "class closure" default
handler code should then store the adjustment objects somewhere.)

=head2 requisition = $widget-E<gt>B<size_request> 

This function is typically used when implementing a GtkContainer subclass.
Obtains the preferred size of a widget. The container uses this information to
arrange its child widgets and decide what size allocations to give them with
size_allocate ().

You can also call this function from an application, with some caveats. Most
notably, getting a size request requires the widget to be associated with a
screen, because font information may be needed. Multihead-aware applications
should keep this in mind.

Also remember that the size request is not necessarily the size a widget will
actually be allocated.

=head2 (width, height) = $widget->B<get_size_request>


Gets the size request that was explicitly set for the widget using
C<set_size_request()>.  A value of -1 for I<width> or I<height> indicates
that the dimension has not been explicitly set and the natural requisition
of the widget will be used instead.
See L<set_size_request()|$widget-E<gt>set_size_request ($width-=1, $height=-1)>.
To get the size a widget will actually use, call
L<size_request()|requisition = $widget-E<gt>size_request ()> instead of
this function.

=for position post_signals

Note that currently signal_chain_from_overridden doesn't work from a
size-request class closure, because the Gtk2::Requisition parameter
you pass ends up getting copied, so changes made to it by the
superclass are lost.  You can still write a class closure for
size-request, but you'll have to calculate the desired size by
yourself, you can't chain up to ask your superclass what it thinks.
