CONSTANTS

19       "EVENT_STOP" and "EVENT_PROPAGATE" are designed for the return from
20       widget event signal handlers and similar, being true to stop or false
21       to propagate.  The names can help you avoid confusion over which way is
22       true and which is false.  (You can also remember the return as meaning
23       "handled", which is the jargon in a few other signal handler types.)

METHODS

29   $widget->set_accel_path ($accel_path, $accel_group)
30       •   $accel_path (string or undef)
31
32       •   $accel_group (Gtk2::AccelGroup or undef)
33
34   object = $widget->get_accessible
35   action or undef = $widget->get_action
36       Since: gtk+ 2.10
37
38   boolean = $widget->activate
39       This function works by emitting an action signal nominated by the
40       various widget subclasses.  The signal is normally called "activate",
41       but it doesn't have to be.
42
43       Currently if you make a widget subclass in Perl there's no way to
44       nominate a signal to be emitted by "$widget->activate".  A signal
45       merely named "activate" is not automatically hooked up.
46
47   $widget->add_accelerator ($accel_signal, $accel_group, $accel_key,
48       $accel_mods, $flags)
49       •   $accel_signal (string)

66
67   rectangle = $widget->allocation
68       Return the current allocated size and position of $widget within its
69       parent widget.  The allocated size is not necessarily the same as the
70       requested size.
71
72       The returned rect object points into $widget and can only be used as
73       long as $widget exists.

75   rectangle = $widget->get_allocation

112       Since: gtk+ 2.18
113

115       •   $can_focus (boolean)

120       •   $direction (Gtk2::DirectionType)

123       •   $child_property (string)
124
125   requisition = $widget->get_child_requisition
126       This function is only for use in widget implementations.  Obtains
127       "$widget->requisition", unless someone has forced a particular geometry
128       on the widget (e.g., with set_usize(), in which case it returns that
129       geometry instead of the widget's requisition.
130
131       This function differs from size_request() in that it retrieves the last
132       size request value from "$widget->requisition", while size_request()
133       actually calls the "size_request" virtual method (that is, emits the
134       "size-request" signal) on the $widget to compute the size request and
135       fill in "$widget->requisition", and only then returns
136       "$widget->requisition".
137
138       Because this function does not call the "size_request" method, it can
139       only be used when you know that "$widget->requisition" is up-to-date.
140       In general, only container implementations have this information;
141       applications should use "size_request ()".

520       You most likely don't want to use any of these functions; synthesizing

522       ways to achieve your goals. For example, use Gtk2::Gdk::invalidate_rect

623       This function works by emitting a setter signal nominated by the
624       various widget types which have "native" scrolling.  The signal is
625       normally called "set-scroll-adjustments", but it doesn't have to be.
626
627       If you make a widget subclass in Perl and create a signal in it called
628       "set-scroll-adjustments" taking two Gtk2::Adjustment parameters then
629       the subclassing automatically hooks that up to be emitted by
630       "$widget->set_scroll_adjustments".  (Your "class closure" default
631       handler code should then store the adjustment objects somewhere.)

683   requisition = $widget->size_request
684       This function is typically used when implementing a GtkContainer
685       subclass.  Obtains the preferred size of a widget. The container uses
686       this information to arrange its child widgets and decide what size
687       allocations to give them with size_allocate ().
688
689       You can also call this function from an application, with some caveats.
690       Most notably, getting a size request requires the widget to be
691       associated with a screen, because font information may be needed.
692       Multihead-aware applications should keep this in mind.
693
694       Also remember that the size request is not necessarily the size a
695       widget will actually be allocated.

699   (width, height) = $widget->get_size_request
700       Gets the size request that was explicitly set for the widget using
701       set_size_request().  A value of -1 for width or height indicates that
702       the dimension has not been explicitly set and the natural requisition
703       of the widget will be used instead.  See set_size_request().  To get
704       the size a widget will actually use, call size_request() instead of
705       this function.
