-/**
- * GtkWidgetFlags:
- * @GTK_TOPLEVEL: widgets without a real parent, as there are #GtkWindow<!-- -->s and
- * #GtkMenu<!-- -->s have this flag set throughout their lifetime.
- * Toplevel widgets always contain their own #GdkWindow.
- * @GTK_NO_WINDOW: Indicative for a widget that does not provide its own #GdkWindow.
- * Visible action (e.g. drawing) is performed on the parent's #GdkWindow.
- * @GTK_REALIZED: Set by gtk_widget_realize(), unset by gtk_widget_unrealize().
- * A realized widget has an associated #GdkWindow.
- * @GTK_MAPPED: Set by gtk_widget_map(), unset by gtk_widget_unmap().
- * Only realized widgets can be mapped. It means that gdk_window_show()
- * has been called on the widgets window(s).
- * @GTK_VISIBLE: Set by gtk_widget_show(), unset by gtk_widget_hide(). Implies that a
- * widget will be mapped as soon as its parent is mapped.
- * @GTK_SENSITIVE: Set and unset by gtk_widget_set_sensitive().
- * The sensitivity of a widget determines whether it will receive
- * certain events (e.g. button or key presses). One premise for
- * the widget's sensitivity is to have this flag set.
- * @GTK_PARENT_SENSITIVE: Set and unset by gtk_widget_set_sensitive() operations on the
- * parents of the widget.
- * This is the second premise for the widget's sensitivity. Once
- * it has %GTK_SENSITIVE and %GTK_PARENT_SENSITIVE set, its state is
- * effectively sensitive. This is expressed (and can be examined) by
- * the #GTK_WIDGET_IS_SENSITIVE macro.
- * @GTK_CAN_FOCUS: Determines whether a widget is able to handle focus grabs.
- * @GTK_HAS_FOCUS: Set by gtk_widget_grab_focus() for widgets that also
- * have %GTK_CAN_FOCUS set. The flag will be unset once another widget
- * grabs the focus.
- * @GTK_CAN_DEFAULT: The widget is allowed to receive the default action via
- * gtk_widget_grab_default() and will reserve space to draw the default if possible
- * @GTK_HAS_DEFAULT: The widget currently is receiving the default action and
- * should be drawn appropriately if possible
- * @GTK_HAS_GRAB: Set by gtk_grab_add(), unset by gtk_grab_remove(). It means that the
- * widget is in the grab_widgets stack, and will be the preferred one for
- * receiving events other than ones of cosmetic value.
- * @GTK_RC_STYLE: Indicates that the widget's style has been looked up through the rc
- * mechanism. It does not imply that the widget actually had a style
- * defined through the rc mechanism.
- * @GTK_COMPOSITE_CHILD: Indicates that the widget is a composite child of its parent; see
- * gtk_widget_push_composite_child(), gtk_widget_pop_composite_child().
- * @GTK_APP_PAINTABLE: Set and unset by gtk_widget_set_app_paintable().
- * Must be set on widgets whose window the application directly draws on,
- * in order to keep GTK+ from overwriting the drawn stuff. See
- * <xref linkend="app-paintable-widgets"/> for a detailed
- * description of this flag.
- * @GTK_RECEIVES_DEFAULT: The widget when focused will receive the default action and have
- * %GTK_HAS_DEFAULT set even if there is a different widget set as default.
- * @GTK_DOUBLE_BUFFERED: Set and unset by gtk_widget_set_double_buffered().
- * Indicates that exposes done on the widget should be
- * double-buffered. See <xref linkend="double-buffering"/> for a
- * detailed discussion of how double-buffering works in GTK+ and
- * why you may want to disable it for special cases.
- * @GTK_NO_SHOW_ALL:
- *
- * Tells about certain properties of the widget.

+ * @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
+ * #GtkSizeRequestMode 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
* 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.
+ * class has already removed margin and alignment. The natural size
+ * passed in should be adjusted in the same way as the allocated size,
