METHODS

  $widget->set_accel_path ($accel_path, $accel_group)

•   $accel_path (string)

•   $accel_group (Gtk2::AccelGroup)

  object = $widget->get_accessible

  action or undef = $widget->get_action
Since: gtk+ 2.10

  boolean = $widget->activate
This function works by emitting an action signal nominated by the various widget subclasses. The signal is normally called "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 "$widget->activate". A signal merely named "activate" is not automatically hooked up.

  $widget->add_accelerator ($accel_signal, $accel_group, $accel_key, $accel_mods, $flags)

•   $accel_signal (string)

•   $accel_group (Gtk2::AccelGroup)

•   $accel_key (integer)

•   $accel_mods (Gtk2::Gdk::ModifierType)

•   $flags (Gtk2::AccelFlags)

  $widget->add_events ($events)

•   $events (Gtk2::Gdk::EventMask)

  $widget->add_mnemonic_label ($label)

•   $label (Gtk2::Widget)

Since: gtk+ 2.4

  rectangle = $widget->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.

  widget or undef = $widget->get_ancestor ($ancestor_package)

•   $ancestor_package (string)

  $widget->app_paintable ($boolean)

  boolean = $widget->app_paintable

  $widget->set_app_paintable ($app_paintable)

•   $app_paintable (boolean)

  boolean = $widget->can_activate_accel ($signal_id)

•   $signal_id (integer)

Since: gtk+ 2.4

  $widget->can_default ($boolean)

  boolean = $widget->can_default

  $widget->can_focus ($boolean)

  boolean = $widget->can_focus

  boolean = $widget->child_focus ($direction)

•   $direction (Gtk2::DirectionType)

  $widget->child_notify ($child_property)

•   $child_property (string)

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

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

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

  $widget->set_child_visible ($is_visible)

  boolean = $widget->event ($event)

•   $event (Gtk2::Gdk::Event)

This rarely-used function emits an event signal on $widget. Don't use this to synthesize events; use "Gtk2->main_do_event" instead. Don't synthesize expose events; use "$gdkwindow->invalidate_rect" instead. Basically, the main use for this in gtk2-perl will be to pass motion notify events to rulers from other widgets.

From gtk+'s API documentation:

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.

  requisition = $widget->requisition
Return the currently desired width and height of $widget. Basically this is the result from the last "size_request" call on $widget, and therefore may not be up-to-date if $widget has asked for a resize but its container parent has not yet called "size_request".

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

  boolean = $widget->set_scroll_adjustments ($hadjustment, $vadjustment)

•   $hadjustment (Gtk2::Adjustment or undef)

•   $vadjustment (Gtk2::Adjustment or undef)

This function works by emitting a setter signal nominated by the various widget types which have "native" scrolling. The signal is normally called "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 "set-scroll-adjustments" taking two Gtk2::Adjustment parameters then the subclassing automatically hooks that up to be emitted by "$widget->set_scroll_adjustments". (Your "class closure" default handler code should then store the adjustment objects somewhere.)

  $widget->size_allocate ($allocation)

•   $allocation (Gtk2::Gdk::Rectangle)

  requisition = $widget->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.

See also get_child_requisition ()

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

  $widget->set_size_request ($width=-1, $height=-1)

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.
