A #GdkWindow is a rectangular region on the screen. It's a low-level object,
used to implement high-level objects such as #GtkWidget and #GtkWindow on the
GTK+ level. A #GtkWindow is a toplevel window, the thing a user might think of 
as a "window" with a titlebar and so on; a #GtkWindow may contain many #GdkWindow. 
For example, each #GtkButton has a #GdkWindow associated with it.

</programlisting></example>
<para>
In the example <xref linkend="composited-window-example"/>, a button is 
placed inside of an event box inside of a window. The event box is 
set as composited and therefore is no longer automatically drawn to 
the screen. 
</para>
<para>
When the contents of the event box change, an expose event is
generated on its parent window (which, in this case, belongs to
the toplevel #GtkWindow). The expose handler for this widget is
responsible for merging the changes back on the screen in the way
that it wishes.
</para>
<para>
In our case, we merge the contents with a 50% transparency. We
also set the background colour of the window to red. The effect is
that the background shows through the button.

<!-- ##### ENUM GdkWindowHints ##### -->
<para>
Used to indicate which fields of a #GdkGeometry struct should be paid attention
to. Also, the presence/absence of @GDK_HINT_POS, @GDK_HINT_USER_POS, and
@GDK_HINT_USER_SIZE is significant, though they don't directly refer to
#GdkGeometry fields.  @GDK_HINT_USER_POS will be set automatically by #GtkWindow
if you call gtk_window_move(). @GDK_HINT_USER_POS and @GDK_HINT_USER_SIZE 
should be set if the user specified a size/position using a --geometry 
command-line argument; gtk_window_parse_geometry() automatically sets these
flags.
</para>

@GDK_HINT_POS: indicates that the program has positioned the window
@GDK_HINT_MIN_SIZE: min size fields are set
@GDK_HINT_MAX_SIZE: max size fields are set
@GDK_HINT_BASE_SIZE: base size fields are set
@GDK_HINT_ASPECT: aspect ratio fields are set
@GDK_HINT_RESIZE_INC: resize increment fields are set
@GDK_HINT_WIN_GRAVITY: window gravity field is set
@GDK_HINT_USER_POS: indicates that the window's position was explicitly set by the user
@GDK_HINT_USER_SIZE: indicates that the window's size was explicitly set by the user

<!-- ##### STRUCT GdkGeometry ##### -->
<para>
The #GdkGeometry struct gives the window manager information about 
a window's geometry constraints. Normally you would set these on 
the GTK+ level using gtk_window_set_geometry_hints(). #GtkWindow 
then sets the hints on the #GdkWindow it creates.
</para>

<para>
gdk_window_set_geometry_hints() expects the hints to be fully valid already and
simply passes them to the window manager; in contrast,
gtk_window_set_geometry_hints() performs some interpretation. For example,
#GtkWindow will apply the hints to the geometry widget instead of the toplevel
window, if you set a geometry widget. Also, the
@min_width/@min_height/@max_width/@max_height fields may be set to -1, and
#GtkWindow will substitute the size request of the window or geometry widget. If
the minimum size hint is not provided, #GtkWindow will use its requisition as
the minimum size.  If the minimum size is provided and a geometry widget is set,
#GtkWindow will take the minimum size as the minimum size of the geometry widget
rather than the entire window. The base size is treated similarly.
</para>

<para>
The canonical use-case for gtk_window_set_geometry_hints() is to get a terminal
widget to resize properly. Here, the terminal text area should be the geometry
widget; #GtkWindow will then automatically set the base size to the size of
other widgets in the terminal window, such as the menubar and scrollbar.  Then,
the @width_inc and @height_inc fields should be set to the size of one character
in the terminal. Finally, the base size should be set to the size of one
character. The net effect is that the minimum size of the terminal 
will have a 1x1 character terminal area, and only terminal sizes on 
the "character grid" will be allowed.
</para>

<para>
Here's an example of how the terminal example would be implemented, assuming 
a terminal area widget called "terminal" and a toplevel window "toplevel":
<informalexample><programlisting>
	GdkGeometry hints;

	hints.base_width = terminal->char_width;
        hints.base_height = terminal->char_height;
        hints.min_width = terminal->char_width;
        hints.min_height = terminal->char_height;
        hints.width_inc = terminal->char_width;
        hints.height_inc = terminal->char_height;

	gtk_window_set_geometry_hints (GTK_WINDOW (toplevel),
				       GTK_WIDGET (terminal),
 				       &amp;hints,
				       GDK_HINT_RESIZE_INC |
                                       GDK_HINT_MIN_SIZE |
                                       GDK_HINT_BASE_SIZE);
</programlisting></informalexample>
</para>

<para>
The other useful fields are the @min_aspect and @max_aspect fields; these
contain a width/height ratio as a floating point number. If a geometry widget is
set, the aspect applies to the geometry widget rather than the entire window.
The most common use of these hints is probably to set @min_aspect and
@max_aspect to the same value, thus forcing the window to keep a constant aspect
ratio.
</para>

@min_width: minimum width of window (or -1 to use requisition, with #GtkWindow only)
@min_height: minimum height of window (or -1 to use requisition, with #GtkWindow only)
@max_width: maximum width of window (or -1 to use requisition, with #GtkWindow only)
@max_height: maximum height of window (or -1 to use requisition, with #GtkWindow only)
@base_width: allowed window widths are @base_width + @width_inc * N where N is any integer (-1 allowed with #GtkWindow)
@base_height: allowed window widths are @base_height + @height_inc * N where N is any integer (-1 allowed with #GtkWindow)
@width_inc: width resize increment
@height_inc: height resize increment
@min_aspect: minimum width/height ratio
@max_aspect: maximum width/height ratio
@win_gravity: window gravity, see gtk_window_set_gravity()

<!-- ##### USER_FUNCTION GdkFilterFunc ##### -->
<para>
Specifies the type of function used to filter native events before they are
converted to GDK events. 
</para>

<para>
When a filter is called, @event is unpopulated, except for
<literal>event-&gt;window</literal>. The filter may translate the native
event to a GDK event and store the result in @event, or handle it without
translation. If the filter translates the event and processing should
continue, it should return <literal>GDK_FILTER_TRANSLATE</literal>.
</para>

@xevent: the native event to filter.
@event: the GDK event to which the X event will be translated.
@data: user data set when the filter was installed.
@Returns: a #GdkFilterReturn value.


<!-- ##### ENUM GdkFilterReturn ##### -->
<para>
Specifies the result of applying a #GdkFilterFunc to a native event.
</para>

@GDK_FILTER_CONTINUE: event not handled, continue processing.
@GDK_FILTER_TRANSLATE: native event translated into a GDK event and stored
                       in the <literal>event</literal> structure that was passed in.
@GDK_FILTER_REMOVE: event handled, terminate processing.

<!-- ##### ENUM GdkModifierType ##### -->
<para>
A set of bit-flags to indicate the state of modifier keys and mouse buttons 
in various event types. Typical modifier keys are Shift, Control, Meta, Super,
Hyper, Alt, Compose, Apple, CapsLock or ShiftLock. 
</para>
<para>
Like the X Window System, GDK supports 8 modifier keys and 5 mouse buttons.
</para>
<para>
Since 2.10, GDK recognizes which of the Meta, Super or Hyper keys are mapped 
to Mod2 - Mod5, and indicates this by setting %GDK_SUPER_MASK, %GDK_HYPER_MASK
or %GDK_META_MASK in the state field of key events.
</para>

@GDK_SHIFT_MASK: the Shift key.
@GDK_LOCK_MASK: a Lock key (depending on the modifier mapping of the 
  X server this may either be CapsLock or ShiftLock).
@GDK_CONTROL_MASK: the Control key.
@GDK_MOD1_MASK: the fourth modifier key (it depends on the modifier 
  mapping of the X server which key is interpreted as this modifier, but 
  normally it is the Alt key).
@GDK_MOD2_MASK: the fifth modifier key (it depends on the modifier 
  mapping of the X server which key is interpreted as this modifier).
@GDK_MOD3_MASK: the sixth modifier key (it depends on the modifier 
  mapping of the X server which key is interpreted as this modifier).
@GDK_MOD4_MASK: the seventh modifier key (it depends on the modifier 
  mapping of the X server which key is interpreted as this modifier).
@GDK_MOD5_MASK: the eighth modifier key (it depends on the modifier 
  mapping of the X server which key is interpreted as this modifier).
@GDK_BUTTON1_MASK: the first mouse button.
@GDK_BUTTON2_MASK: the second mouse button.
@GDK_BUTTON3_MASK: the third mouse button.
@GDK_BUTTON4_MASK: the fourth mouse button.
@GDK_BUTTON5_MASK: the fifth mouse button.
@GDK_SUPER_MASK: the Super modifier. Since 2.10
@GDK_HYPER_MASK: the Hyper modifier. Since 2.10
@GDK_META_MASK: the Meta modifier. Since 2.10
@GDK_RELEASE_MASK: not used in GDK itself. GTK+ uses it to differentiate 
  between (keyval, modifiers) pairs from key press and release events.
@GDK_MODIFIER_MASK: a mask covering all modifier types.

which can be set using gdk_set_pointer_hooks().
</para>
<para>
This is only useful for such low-level tools as an event recorder. 
Applications should never have any reason to use this facility
</para>

@get_pointer: Obtains the current pointer position and modifier state.
  The position is given in coordinates relative to the window containing 
  the pointer, which is returned in @window.
@window_at_pointer: Obtains the window underneath the mouse pointer, 
  returning the location of that window in @win_x, @win_y. Returns %NULL 
  if the window under the mouse pointer is not known to GDK (for example, 
  belongs to another application).
