+HANDLING WIDGET STYLES
+======================
+
+
+A widget gets created with a default style.
+The global default style can be affected by gtk_widget_set_default_style()
+and can be queried by gtk_widget_get_default_style().
+The initial style that is assigned to a widget as default style upon
+creation can be affected by wrapping the widget's creation as follows:
+gtk_widget_push_style (my_style);
+widget = gtk_type_new (gtk_button_get_type ());
+gtk_widget_pop_style ();
+
+There are certain functions to affect widget styles after a widget's
+creation:
+
+gtk_widget_set_style ()
+  Save the default style and set a user style.
+  This will override a previously set user style or
+  previously set rc styles.
+
+gtk_widget_reset_rc_styles ()
+  Descends through a widget hierarchy and sets the rc style
+  on all widgets that don't have a user style set.
+
+gtk_widget_ensure_style ()
+  Ensure that the widget either has a user style set, or an rc lookup
+  has been performed.
+
+gtk_rc_get_style ()
+  Return an rc style for a widget if there is one.
+
+gtk_widget_set_name ()
+  Change widget name, and perform a new rc lookup if no user style
+  is set.
+
+gtk_widget_realize ()
+  Besides realizing the widget this function will:
+  - perform an rc lookup if necessary,
+  - attach a widget's style.
+
+gtk_widget_get_style ()
+  Return a widgets style, this function will perform an rc lookup
+  if necessary.
+
+gtk_widget_set_parent ()
+  This function will perform rc lookups recursively for all widgets
+  that do not have a user style set.
+
+gtk_style_copy ()
+  This function can be used to copy a widget's style.
+  The style can subsequently be changed (e.g., by modifications to the
+  red/green/blue values of a certain color) and then be applied to the
+  widget via gtk_widget_set_style().
+
+
+GtkWidget::style_set
+  This signal will be emitted for a widget once its style changes with
+  an additional argument previous_style which will hold the widget->style
+  value from a previous emission.
+  The initial emission of this signal is guaranteed to happen prior
+  to any GtkWidget::size_request emission, and will have the previous_style
+  argument set to NULL.
+  The GtkWidgetClass implements a default handler for this signal that
+  will set the widget's window's background of widgets that provide their
+  own windows according to the new style.
+  Derived widgets need to override this default handler, if:
+  - their size requisition depends on the current style.
+    (e.g., on the style's fonts)
+  - they set the background of widget->window to something other than.
+    style->bg. (e.g., GtkListItem)
+  - the widget provides windows other than widget->window.
+  - the widget has any other stored dependencies on the style.
+                   
+
+
+Flag indications:
+
+!GTK_RC_STYLE && !GTK_USER_STYLE:
+  The widget has its default style set, no rc lookup has been
+  performed, the widget has not been size requested yet and is
+  therefore not yet realized.
+
+GTK_USER_STYLE:
+  GTK_RC_STYLE is not set.
+  The widget has a user style assigned, and its default style has been
+  saved.
+
+GTK_RC_STYLE:
+  GTK_USER_STYLE is not set.
+  If the widget has a saved default style, it has been assigned an
+  rc style. If the widget does not have a saved default style, it still
+  has its default style but an rc lookup has already been performed.

+Notes about the inner workings of the widget system of GTK
+==========================================================
+
+This file contains some notes as to how the widget system does
+and should work. It consists of three parts:
+
+ I) A description of the meaning of the various flags
+
+ II) A list of invariants about the states of the widgets. 
+    (Throughout this document, we refer to the states of the
+     widgets by referring to the flags for GtkWidget)
+
+ III) Some notes about the ways that a widget changes states
+
+ IV) A list of responsibilities of various widget signals when
+    the states change.
+
+Any action necessary to maintain the invariants in II which is not
+explicitly mentioned in IV), is the responsibility of the core GTK
+code, which is roughly defined as:
+
+  gtkobject.c
+  gtkwidget.c
+  gtkcontainer.c
+  gtkmain.c
+  gtksignal.c
+
+Section II is mostly of interest to those maintaining GTK, the
+other sections may also be interesting to people writing
+new widgets.
+
+Main outline:
+	- Owen Taylor <owt1@cornell.edu>
+	  1998/02/03
+
+Flag descriptions:
+	- Tim Janik <timj@gimp.org>
+	  1998/02/04
+
+I. Flags
+--------
+
+GtkObject:
+
+GTK_DESTROYED:
+	This flagged is set for a GtkObject right before its
+	destruction code is executed. Its main use is the
+	prevention of multiple destruction invocations.
+	
+GTK_FLOATING:
+	This flag reflects the fact that the holder of the
+	initial reference count is unknown. Refer to refcounting.txt
+	for further details.
+
+GTK_RESERVED_1:
+GTK_RESERVED_2:
+	Reserved flags.
+
+
+GtkWidget, public flags:
+
+GTK_TOPLEVEL:
+	Widgets without a real parent, as there are GtkWindows and
+	GtkMenus have this flag set throughout their lifetime.
+	Toplevel widgets always contain their own GdkSurface.
+	
+GTK_NO_WINDOW:
+	This flag is indicative for a widget that does not provide
+	its own GdkSurface. Visible action (e.g. drawing) is performed
+	on the parent's GdkSurface.
+
+GTK_REALIZED:
+	Set by gtk_widget_realize, unset by gtk_widget_unrealize.
+	Relies on ((widget->parent && widget->parent->window)
+	           || GTK_WIDGET_TOPLEVEL (widget));
+	Means: widget has an associated GdkSurface (XWindow).
+
+GTK_MAPPED:
+	Set by gtk_widget_map, unset by gtk_widget_unmap.
+	May only be set if GTK_WIDGET_REALIZED (widget).
+	Means: gdk_surface_show() has been called on the widgets window(s).
+
+GTK_VISIBLE:
+	Set by gtk_widget_show.
+	Implies that a widget will be flagged GTK_MAPPED as soon as its
+	parent is mapped.
+!GTK_VISIBLE:
+	Set by gtk_widget_hide.
+	Implies that a widget is not onscreen, therefore !GTK_MAPPED.
+
+GTK_CHILD_VISIBLE
+        Set by gtk_widget_set_child_visible, and if FALSE indicates that 
+        the widget should not be mapped even if the parent is mapped
+        and visible. Containers like GtkNotebook use this flag.
+        A private flag, not a public flag, so if you need to check
+        this flag, you should call gtk_widget_get_child_visible().
+        (Should be very rarely necessary.)
+
+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 widgets sensitivity is to have GTK_SENSITIVE 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 widgets 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:
+	There are no directly corresponding functions for setting/unsetting
+	this flag, but it can be affected by the GtkWidget::has_focus argument
+	via gtk_widget_set_arg.
+	This flag determines whether a widget is able to handle focus grabs.
+
+GTK_HAS_FOCUS:
+	This flag will be 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:
+GTK_HAS_DEFAULT:
+	These two flags are mostly equal in functionality to their *_FOCUS
+	counterparts, but for the default widget.
+
+GTK_HAS_GRAB:
+	Set by gtk_grab_add, unset by gtk_grab_remove.
+	Means: widget is in the grab_widgets stack, and will be the preferred
+	one for receiving events other than ones of cosmetic value.
+
+GTK_BASIC:
+	The GTK_BASIC flag is an attempt at making a distinction
+	between widgets that handle user input e.g. key/button presses
+	and those that don't. Subsequent parent<->child relation ships
+	of non `basic' widgets should be avoided. The checking for
+	this is currently not properly enforced in the code. For
+	example GtkButton is a non `basic' widget, that will therefore
+	disallow to act as a container for another GtkButton. Now the
+	gnit is, one can add a GtkHBox (which is a `basic' widget) to
+	the first button, and put the second into the box.
+
+GTK_RESERVED_3:
+
+GTK_RC_STYLE:
+	This flag indicates that its 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.
+
+
+GtkWidget, private flags:
+
+GTK_USER_STYLE:
+	A widget is flagged to have a user style, once gtk_widget_set_style
+	has been invoked for it. The use of this flag is to tell widgets
+	which share a global user style from the ones which got a certain
+	style assign from outside the toolkit.
+	
+GTK_RESIZE_PENDING:
+	First, this is only valid for GtkContainers.
+	[some of the code should move to gtkcontainer.c therefore]
+	Relies on GTK_WIDGET_REALIZED(widget)
+	[this is not really enforced throughout the code, but should
+	 be. it only requires a few checks for GTK_WIDGET_REALIZED and
+	 minor changes to gtk_widget_unrealize, we can then remove the check
+	 in gtk_widget_real_destroy]
+	Means: there is an idle handler waiting for the container to
+	resize it.
+
+GTK_RESIZE_NEEDED:
+	Relies on GTK_WIDGET_REALIZED(widget)
+	[this is not really enforced throughout the code, but should
+	 be. once this is done special checking in gtk_widget_real_destroy
+	 can be avoided]
+	Means: a widget has been added to the resize_widgets list of
+	its _toplevel_ container (keep this in mind for GtkViewport).
+	Remark: this flag is also used internally by gtkwindow.c during
+	the evaluation of resizing worthy widgets.
+
+GTK_LEAVE_PENDING:
+	A widget is flagged as such if there is a leave_notify event
+	pending for it. It will receive this event regardless of a grab
+	through another widget or its current sensitivity.
+	[this should be made relying on GTK_REALIZED]
+
+GTK_HAS_SHAPE_MASK:
+	Set by gtk_widget_shape_combine_mask if a widget got a shape mask
+	assigned (making use of the X11 shaped window extension).
+
+GTK_IN_REPARENT:
+	During the act of reparentation widgets which are already
+	realized and will be added to an already realized parent need
+	to have this flag set to prevent natural unrealization on the
+	process of getting unparented.
+
+GTK_NEED_REQUEST:
+	This flag is set if the widget doesn't have an up to date 
+	requisition. If this flag is set, we must actually emit ::size-request
+        when gtk_widget_size_request() is called. Otherwise, we can
+        simply widget->requisition. We keep track of this all the time
+        however, widgets with this flag set are only added to the resize 
+	queue if they are viewable.
+
+GTK_NEED_ALLOCATION:
+	This flag is set if the widget doesn't have an up to date 
+	allocation. If this flag is set, we must actually emit ::size-allocate
+        when gtk_widget_size_allocate() is called, even if the new allocation
+        is the same as the current allocation.
+ 
+Related Macros:
+
+GTK_WIDGET_DRAWABLE:
+	This macro examines whether a widget is flagged as GTK_WIDGET_VISIBLE
+	and GTK_WIDGET_MAPPED.
+	Means: it _makes sense_ to draw in a widgets window.
+
+GTK_WIDGET_IS_SENSITIVE:
+	This macro tells the real sensitivity state of a widget. It returns
+	whether both the widget and all its parents are in sensitive state.
+
+
+II. Invariants:
+---------------
+
+This section describes various constraints on the states of 
+the widget:
+
+In the following
+
+  A => B     means  if A is true, than B is true
+  A <=> B    means  A is true, if and only if B is true
+                    (equivalent to A => B and A <= B)
+
+
+1)  GTK_WIDGET_DESTROYED (widget) => !GTK_WIDGET_REALIZED (widget)
+                                  => !GTK_WIDGET_VISIBLE (widget)
+[ The latter is not currently in place, but it should be ] 
+ 
+2) GTK_WIDGET_MAPPED (widget) => GTK_WIDGET_REALIZED (widget)
+
+3) if GTK_WIDGET_TOPLEVEL (widget):
+   GTK_WIDGET_VISIBLE (widget) <=> GTK_WIDGET_MAPPED (widget)
+
+4) if !GTK_WIDGET_TOPLEVEL (widget):
+  widget->parent && GTK_WIDGET_REALIZED (widget->parent) <=>
+     GTK_WIDGET_REALIZED (widget)
+
+5) if !GTK_WIDGET_TOPLEVEL (widget):
+
+   GTK_WIDGET_MAPPED (widget) => GTK_WIDGET_VISIBLE (widget)
+                              => GTK_WIDGET_CHILD_VISIBLE (widget)
+                              => GTK_WIDGET_REALIZED (widget)
+
+   widget->parent && GTK_WIDGET_MAPPED (widget->parent) && 
+     GTK_WIDGET_VISIBLE (widget) && GTK_WIDGET_CHILD_VISIBLE 
+       <=> GTK_WIDGET_MAPPED (widget)
+
+Note:, the definition
+
+[  GTK_WIDGET_DRAWABLE = GTK_WIDGET_VISIBLE && GTK_WIDGET_MAPPED
+   is made in gtkwidget.h, but by 3) and 5), 
+     
+      GTK_WIDGET_MAPPED => GTK_WIDGET_VISIBLE
+]
+
+6) GTK_REDRAW_PENDING => GTK_WIDGET_REALIZED
+   GTK_RESIZE_PENDING =>         "
+   GTK_LEAVE_PENDING  =>         "
+   GTK_RESIZE_NEEDED  =>         "
+
+III. How states are changed:
+----------------------------
+
+How can the user control the state of a widget:
+-----------------------------------------------
+
+(In the following, set flag means set the flag, do appropriate
+actions, and enforce above invariants) 
+
+gtk_widget_show: 
+ if !GTK_DESTROYED sets GTK_VISIBLE
+
+gtk_widget_hide:
+ if !GTK_VISIBLE for widget
+
+gtk_widget_destroy:
+ sets GTK_DESTROYED
+ For a top-level widget
+
+gtk_widget_realize:
+ if !GTK_DESTROYED sets GTK_REALIZED
+- Calling gtk_widget_realize when the widget is not a descendant
+  of a toplevel is an ERROR.
+
+gtk_container_add (container, widget) [ and container-specific variants ]
+ Sets widget->parent 
+
+gtk_container_remove (container, widget)
+ unsets widget->parent
+
+gtk_widget_reparent (widget, new_parent)
+ Equivalent to removing widget from old parent and adding it to
+ the new parent, except that the widget will not be temporarily 
+ unrealized if both the old parent and the new parent are realized.
+
+
+gtk_widget_unrealize
+gtk_widget_map
+gtk_widget_unmap
+
+These functions are not meant to be used by applications - they
+are used only by GTK and widgets to enforce invariants on the
+state.
+
+When The X window corresponding to a GTK window is destroyed:
+-------------------------------------------------------------
+
+gtk_widget_destroy is called (as above).
+
+
+
+IV. Responsibilities of widgets
+--------------------------------
+
+Adding to a container
+---------------------
+
+When a widget is added to a container, the container:
+
+  1) calls gtk_widget_set_parent_surface (widget, window) if 
+     the widget is being added to something other than container->window
+  2) calls gtk_widget_set_parent (widget, container)
+
+Removing from a container
+-------------------------
+
+When a widget is removed to a container, the container:
+
+  1) Calls gtk_widget_unparent (widget)
+  2) Queues a resize.
+
+Notes:
+
+ gtk_widget_unparent unrealizes the widget except in the 
+   special case GTK_IN_REPARENT is set.
+
+
+At widget creation
+------------------
+
+Widgets are created in an unrealized state. 
+
+ 1) The widget should allocate and initialize needed data structures
+
+
+The Realize signal
+------------------
+
+When a widget receives the "realize" signal it should:
+
+ NO_WINDOW widgets: (probably OK to use default handler)
+
+  1) set the realized flag
+  2) set widget->window
+      widget->window = gtk_widget_get_parent_surface (widget);
+      g_object_ref (widget->window);
+  3) attach the widget's style
+
+  widget->style = gtk_style_attach (widget->style, widget->window);
+
+ widget with window(s)
+
+  1) set the REALIZED flag
+  2) create windows with the parent obtained from
+      gtk_widget_get_parent_surface (widget);
+  3) attach the widget's style
+  4) set the background color for the new window based on the style
+
+The Map signal
+--------------
+
+  1) Set the MAPPED flag
+  2) If the widget has any windows, gdk_surface_show those windows
+  3) call gtk_widget_map for all child widgets that are 
+     VISIBLE, CHILD_VISIBLE and !MAPPED. (A widget will only
+     be !CHILD_VISIBLE if the container set it that way, so
+     most containers will not have to check this.)
+  3) Do any other functions related to putting the widget onscreen.
+     (for instance, showing extra popup windows...)
+
+The Unmap signal
+----------------
+
+When a widget receives the unmap signal, it must:
+
+ 1) If the widget has a window, gdk_surface_hide that window, 
+ 2) If the widget does not have a window, unmap all child widgets
+ 3) Do any other functions related to taking the widget offscreen
+     (for instance, removing popup windows...)
+ 4) Unset GTK_MAPPED
+
+
+The Unrealize signal
+--------------------
+
+When a widget receives the unrealize signal, it must
+
+ 1) For any windows other than widget->window do:
+
+    gdk_surface_set_user_data (window, NULL);
+    gdk_surface_destroy (window);
+
+ 2) Call the parent's unrealize handler
+
+
+The Widget class unrealize handler will take care of unrealizing
+all children if necessary. [should this be made consistent with
+unmap???]
+
+
+The Destroy Signal
+------------------
+
+Commentary:
+
+  The destroy signal probably shouldn't exist at all. A widget
+  should merely be unrealized and removed from its parent
+  when the user calls gtk_widget_destroy or a GDK_DESTROY event
+  is received. However, a large body of code depends on
+  getting a definitive signal when a widget goes away.
+
+  That could be put in the finalization step, but, especially
+  with language bindings, the cleanup step may need to refer
+  back to the widget. (To use gtk_widget_get_data, for instance)
+  If it does so via a pointer in a closure (natural for
+  Scheme, or Perl), then the finalization procedure will never
+  be called. 
+
+  Also, if we made that the finalization step, we would have
+  to propagate the GDK_DESTROY event in any case, since it is
+  at that point at which user-visible actions need to be taken.
+
+
+When a widget receives the destroy signal, it must:
+
+  1) If the widget "owns" any widgets other than its child
+     widgets, (for instance popup windows) it should
+     call gtk_widget_destroy () for them.
+
+  2) Call the parent class's destroy handler.
+
+
+The "destroy" signal will only be received once. A widget
+will never receive any other signals after the destroy
+signal (but see the section on "Finalize" below)
+
+The widget must handle calls to all publically accessible
+functions in an innocuous manner even after a "destroy"
+signal. (A widget can assume that it will not be realized 
+after a "destroy" signal is received, which may simplify
+handling this requirement)
+
+
+The Finalize Pseudo-signal
+--------------------------
+
+The finalize pseudo-signal is received after all references
+to the widget have been removed. The finalize callback
+cannot make any GTK calls with the widget as a parameter.
+
+1) Free any memory allocated by the widget. (But _not_
+   the widget structure itself.
+
+2) Call the parent class's finalize signal
+
+
+A note on chaining "destroy" signals and finalize signals:
+---------------------------------------------------------
+
+This is done by code like:
+
+  if (GTK_OBJECT_CLASS (parent_class)->destroy)
+    (* GTK_OBJECT_CLASS (parent_class)->destroy) (object);
+
+It may not be completely obvious why this works. Note
+that parent_class is a static variable on a per-class
+basis. So say: we have
+
+  GtkFoo <- GtkBar <- GtkWidget <-GtkObject
+
+And that Foo, Widget, and Object all have destructors, but
+not Bar.
+
+Then gtk_foo_destroy will call gtk_widget_destroy (because
+it was not overridden in the Bar class structure) and
+gtk_widget_destroy will call gtk_object_destroy because
+the parent_class variable referenced by gtk_foo_destroy is the 
+static variable in gtkwidget.c: GtkObjectClass.
