/**
* GtkWidgetClass:
* @parent_class: The object class structure needs to be the first
* element in the widget class structure in order for the class mechanism
* to work correctly. This allows a GtkWidgetClass pointer to be cast to
* a GObjectClass pointer.
* @activate_signal: The signal to emit when a widget of this class is
* activated, gtk_widget_activate() handles the emission.
* Implementation of this signal is optional.
* @get_request_mode: This allows a widget to tell its parent container whether
* it prefers to be allocated in %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH or
* %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT mode.
* %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH means the widget prefers to have
* #GtkWidgetClass.get_preferred_width() called and then
* #GtkWidgetClass.get_preferred_height_for_width().
* %GTK_SIZE_REQUEST_CONSTANT_SIZE disables any height-for-width or
* width-for-height geometry management for a said widget and is the
* default return.
* It's important to note (as described below) that any widget
* which trades height-for-width or width-for-height must respond properly
* to both of the virtual methods #GtkWidgetClass.get_preferred_height_for_width()
* and #GtkWidgetClass.get_preferred_width_for_height() since it might be
* queried in either #GtkSizeRequestMode by its parent container.
* @get_preferred_height: This is called by containers to obtain the minimum
* and natural height of a widget. A widget that does not actually trade
* any height for width or width for height only has to implement these
* two virtual methods (#GtkWidgetClass.get_preferred_width() and
* #GtkWidgetClass.get_preferred_height()).
* @get_preferred_width_for_height: This is analogous to
* #GtkWidgetClass.get_preferred_height_for_width() except that it
* operates in the oposite orientation. It's rare that a widget actually
* does %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT requests but this can happen
* when, for example, a widget or container gets additional columns to
* compensate for a smaller allocated height.
* @get_preferred_width: This is called by containers to obtain the minimum
* and natural width of a widget. A widget will never be allocated a width
* less than its minimum and will only ever be allocated a width greater
* than the natural width once all of the said widget's siblings have
* received their natural widths.
* Furthermore, a widget will only ever be allocated a width greater than
* its natural width if it was configured to receive extra expand space
* from its parent container.
* @get_preferred_height_for_width: This is similar to
* #GtkWidgetClass.get_preferred_height() except that it is passed a
* contextual width to request height for. By implementing this virtual
* method it is possible for a #GtkLabel to tell its parent how much height
* would be required if the label were to be allocated a said width.
* @adjust_size_request: Convert an initial size request from a widget's
* #GtkSizeRequest virtual method implementations into a size request to
* be used by parent containers in laying out the widget.
* adjust_size_request adjusts <emphasis>from</emphasis> a child widget's
* original request <emphasis>to</emphasis> what a parent container should
* use for layout. The @for_size argument will be -1 if the request should
* not be for a particular size in the opposing orientation, i.e. if the
* request is not height-for-width or width-for-height. If @for_size is
* greater than -1, it is the proposed allocation in the opposing
* orientation that we need the request for. Implementations of
* adjust_size_request should chain up to the default implementation,
* which applies #GtkWidget's margin properties and imposes any values
* from gtk_widget_set_size_request(). Chaining up should be last,
* <emphasis>after</emphasis> your subclass adjusts the request, so
* #GtkWidget can apply constraints and add the margin properly.
* @adjust_size_allocation: Convert an initial size allocation assigned
* by a #GtkContainer using gtk_widget_size_allocate(), into an actual
* size allocation to be used by the widget. adjust_size_allocation
* adjusts <emphasis>to</emphasis> a child widget's actual allocation
* <emphasis>from</emphasis> what a parent container computed for the
* child. The adjusted allocation must be entirely within the original
* allocation. In any custom implementation, chain up to the default
* #GtkWidget implementation of this method, which applies the margin
* and alignment properties of #GtkWidget. Chain up
* <emphasis>before</emphasis> performing your own adjustments so your
* own adjustments remove more allocation after the #GtkWidget base
* class has already removed margin and alignment. The natural size
* passed in should be adjusted in the same way as the allocated size,
* which allows adjustments to perform alignments or other changes
* based on natural size.
