  * GtkCellAreaClass:
  * @add: adds a #GtkCellRenderer to the area.

- * @foreach: Calls the #GtkCellCallback function on every #GtkCellRenderer in the area
- * with the provided user data until the callback returns %TRUE.
- * @foreach_alloc: Calls the #GtkCellAllocCallback function on every #GtkCellRenderer in the area
- * with the allocated area for the cell and the provided user data until the callback returns %TRUE.
- * @event: Handle an event in the area, this is generally used to activate a cell
- * at the event location for button events but can also be used to generically pass
- * events to #GtkWidgets drawn onto the area.
- * @render: Actually render the area's cells to the specified rectangle, @background_area
- * should be correctly distributed to the cells coresponding background areas.
- * @apply_attributes: Apply the cell attributes to the cells. This is implemented as a signal and 
- * generally #GtkCellArea subclasses dont need to implement this since it's handled by the base 
- * class but can be overridden to apply some custom attributes.
- * @create_context: Creates and returns a class specific #GtkCellAreaContext to store cell 
- * alignment and allocation details for a said #GtkCellArea class.
- * @copy_context: Creates a new #GtkCellAreaContext in the same state as the passed @context
- * with any cell alignment data and allocations in tact.
- * @get_request_mode: This allows an area to tell its layouting widget whether it prefers to 
- * be allocated in %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH or %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT mode.
- * @get_preferred_width: Calculates the minimum and natural width of the area's cells
- * with the current attributes applied while considering the particular layouting details
- * of the said #GtkCellArea. While requests are performed over a series of rows, alignments
- * and overall minimum and natural sizes should be stored in the corresponding #GtkCellAreaContext.
- * @get_preferred_height_for_width: Calculates the minimum and natural height for the area
- * if the passed @context would be allocated the given width. When implementing this virtual
- * method it is safe to assume that @context has already stored the aligned cell widths
- * for every #GtkTreeModel row that @context will be allocated for since this information
- * was stored at #GtkCellAreaClass.get_preferred_width() time. This virtual method should
- * also store any necessary alignments of cell heights for the case that the context is
- * allocated a height.
- * @get_preferred_height: Calculates the minimum and natural height of the area's cells
- * with the current attributes applied. Essentially this is the same as

- * %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT mode.
- * @set_cell_property: This should be implemented to handle changes in child cell properties
- * for a given #GtkCellRenderer that were previously installed on the #GtkCellAreaClass with 
- * gtk_cell_area_class_install_cell_property().
- * @get_cell_property: This should be implemented to report the values of child cell properties
- * for a given child #GtkCellRenderer.
- * @focus: This virtual method should be implemented to navigate focus from cell to cell
- * inside the #GtkCellArea. The #GtkCellArea should move focus from cell to cell inside
- * the area and return %FALSE if focus logically leaves the area with the following exceptions:
- * When the area contains no activatable cells, the entire area recieves focus. Focus should not
- * be given to cells that are actually "focus siblings" of other sibling cells 
- * (see gtk_cell_area_get_focus_from_sibling()). Focus is set by calling gtk_cell_area_set_focus_cell().
- * @is_activatable: Returns whether the #GtkCellArea can respond to #GtkCellAreaClass.activate(), 
- * usually this does not need to be implemented since the base class takes care of this however
- * it can be enhanced if the #GtkCellArea subclass can handle activation in other ways than
- * activating its #GtkCellRenderers.
- * @activate: This is called when the layouting widget rendering the #GtkCellArea activates
- * the focus cell (see gtk_cell_area_get_focus_cell()).
+ * @foreach: calls the #GtkCellCallback function on every #GtkCellRenderer in
