<div class="SECT1">
<h1 class="SECT1">
<a name="SEC-GDKWINDOW"><span class="STRUCTNAME">
GdkWindow</span></a>
</h1>
<p>
<span class="STRUCTNAME">GdkWindow</span> is a wrapper
around Xlib's <span class="STRUCTNAME">Window</span>
object. (It was discussed briefly in <a href=
"z57.html#SEC-REALIZINGSHOWING">the section called <i>
Realizing, Mapping, and Showing</i> in the chapter called
<i>GTK+ Basics</i></a>.) A <span class="STRUCTNAME">
GdkWindow</span> represents a region on the screen. It can
be shown or hidden (called <i class="FIRSTTERM">mapping</i>
and <i class="FIRSTTERM">unmapping</i> the window in Xlib).
You can capture events received by a <span class=
"STRUCTNAME">GdkWindow</span>, draw graphics inside it, and
move or resize it. <span class="STRUCTNAME">
GdkWindow</span>s are arranged in a tree structure; that
is, each window can have child windows. Child windows are
positioned relative to their parent window, and move when
the parent moves. Child windows don't draw outside of their
parent's bounds (i.e. they are clipped by the parent
window).
</p>
<p>
The tree of <span class="STRUCTNAME">GdkWindow</span>s is
not specific to each application; there is a global tree of
windows controlled by the X server and the window manager.
The <i class="FIRSTTERM">root window</i> has no parent; all
windows derive from it. All or part of it is visible as
your desktop background. Each window can be owned by a
different UNIX process; some windows will be created by the
window manager, some will come from user applications.
</p>
<p>
<span class="STRUCTNAME">GdkWindow</span> and <tt class=
"CLASSNAME">GtkWindow</tt> are very different things; <tt
class="CLASSNAME">GtkWindow</tt> is a GTK+ widget used to
represent toplevel windows (toplevel windows are the
highest application-controlled windows in the window
hierarchy). Window managers typically create <i class=
"FIRSTTERM">decorations</i> for toplevel windows;
decorations include title bars, close buttons, and the
like.
</p>
<p>
It's important to understand that an X window is primarily
an object on the X server. X clients receive a unique
integer ID for each window, and refer to windows by ID.
Thus, all window operations take place on the server; all
functions that deal with X windows go across the network.
</p>
<p>
<span class="STRUCTNAME">GdkWindow</span> is a wrapper
around the integer ID returned by X. It does keep local
copies of some information (such as the window's
dimensions), so some GDK operations are more efficient than
the corresponding Xlib operations. Still, <span class=
"STRUCTNAME">GdkWindow</span> is essentially a handle for a
server-side object. Many GDK objects are similar; fonts,
pixmaps, cursors, and so on are also handles for
server-side objects.
</p>
<div class="SECT2">
<h2 class="SECT2">
<a name="Z113"><span class="STRUCTNAME">GdkWindow</span>
and <span class="STRUCTNAME">GtkWidget</span></a>
</h2>
<p>
Many <span class="STRUCTNAME">GtkWidget</span> subclasses
have an associated <span class="STRUCTNAME">
GdkWindow</span>. In theory, GTK+ applications could
create only toplevel windows, and have all widgets draw
into them. However, it would make little sense to do so;
<span class="STRUCTNAME">GdkWindow</span> allows the X
Window System to automatically handle many details. For
example, events received from GDK are marked with the
window they occurred in; GTK+ can rapidly determine which
widget each event corresponds to.
</p>
<p>
There are some widgets with no associated <span class=
"STRUCTNAME">GdkWindow</span>; these are called "no
window" widgets, an allusion to the <span class=
"STRUCTNAME">GTK_NO_WINDOW</span> flag that marks them.
(You can test this flag with the macro <tt class=
"FUNCTION">GTK_WIDGET_NO_WINDOW()</tt>.) Widgets without
a window render themselves into their parent container's
<span class="STRUCTNAME">GdkWindow</span>. Windowless
widgets are relatively small and lightweight; <tt class=
"CLASSNAME">GtkLabel</tt> is the most common example.
Because events are always received on a <span class=
"STRUCTNAME">GdkWindow</span>, windowless widgets do not
receive events. (The <tt class="CLASSNAME">
GtkEventBox</tt> container can be used if you need to
capture events on a windowless widget.)
</p>
</div>
<div class="SECT2">
<h2 class="SECT2">
<a name="SEC-GDKWINATTR"><span class="STRUCTNAME">
GdkWindow</span> Attributes</a>
</h2>
<p>
<tt class="FUNCTION">gdk_window_new()</tt> (shown in <a
href="sec-gdkwindow.html#FL-GDKWINNEW">Figure 1</a>)
allows you to specify all of a window's attributes when
you create it; many of them can be changed later as well.
To specify a block of attributes, you pass in a <span
class="STRUCTNAME">GdkWindowAttr</span> object; its
contents will give you an idea what attributes a <span
class="STRUCTNAME">GdkWindow</span> can have:
</p>
<table border="0" bgcolor="#E0E0E0" width="100%">
<tr>
<td>
<pre class="PROGRAMLISTING">
typedef struct _GdkWindowAttr GdkWindowAttr;
struct _GdkWindowAttr
{
gchar *title;
gint event_mask;
gint16 x, y;
gint16 width;
gint16 height;
GdkWindowClass wclass;
GdkVisual *visual;
GdkColormap *colormap;
GdkWindowType window_type;
GdkCursor *cursor;
gchar *wmclass_name;
gchar *wmclass_class;
gboolean override_redirect;
};
</pre>
</td>
</tr>
</table>
<p>
Because some of the fields in <span class="STRUCTNAME">
GdkWindowAttr</span> are optional, <tt class="FUNCTION">
gdk_window_new()</tt> is used with an <span class=
"STRUCTNAME">attributes_mask</span> to specify which
optional fields contain valid information (bit flags are
available representing each optional field). GDK will
only examine the optional fields given in the mask, so
you can let the default values remain for fields you
aren't interested in. <a href=
"sec-gdkwindow.html#TAB-GDKWINDOWATTR">Table 1</a>
summarizes them briefly; fields with no <span class=
"STRUCTNAME">attributes_mask</span> flag are required and
have no default value.
</p>
<p>
<tt class="FUNCTION">gdk_window_new()</tt> is typically
used in widget implementations to create the widget's
<span class="STRUCTNAME">GdkWindow</span>; you will
rarely use it in any other context. <tt class="FUNCTION">
gdk_window_destroy()</tt> destroys a window when you are
done with it. Windows are also reference counted; be sure
to read <a href="sec-gdkresourcemgmt.html">the section
called <i>GDK Resource Management</i></a> for more
details on this.

<p>
A <span class="STRUCTNAME">GdkWindow</span>'s title is
only really important for toplevel windows; most window
managers will place it in the titlebar. Usually you
should not specify it when creating a <span class=
"STRUCTNAME">GdkWindow</span>, however; instead, let your
widget's users call <tt class="FUNCTION">
gtk_window_set_title()</tt>.
</p>
<p>
The window's event mask determines which events will be
received on this window; <a href="sec-gdkevent.html">the
section called <i>Events</i></a> goes into more detail
about events.
</p>
<p>
The X and Y coordinates for a window are specified in
pixels, relative to the parent window's origin. The
origin of each window is its top left ("northwest")
corner. Notice that a 16-bit signed integer is used; X
windows have a maximum size of 32768 pixels. Negative
values are allowed, but the window will be clipped by its
parent window (only the portion inside the parent window
will be visible).
</p>
<p>
The width and height of a window are given in pixels, and
are also 16-bit signed integers.
</p>
<p>
A window's <span class="STRUCTNAME">GdkWindowClass</span>
can have one of two values:
</p>
<ul>
<li>
<p>
<span class="STRUCTNAME">GDK_INPUT_OUTPUT</span> is a
normal window.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">GDK_INPUT_ONLY</span> is a
window that has a position and receives events but
has no visual representation. Its children must also
be input only. You can set the cursor and other
attributes for an input only window, but there is no
way to draw to it (it's invisible). Input-only
windows are occasionally useful to capture events or
change the cursor in a region that overlaps two
normal windows.
</p>
</li>
</ul>
<p>
A <i class="FIRSTTERM">visual</i> describes the
color-handling characteristics of a display; a <i class=
"FIRSTTERM">colormap</i> contains the colors you can use
to draw. <a href="sec-gdkvisual.html">the section called
<i>Visuals and Colormaps</i></a> gives details on visuals
and colormaps.
</p>
<p>
Windows can be one of several different types, specified
by the <span class="STRUCTNAME">GdkWindowType</span>
enumeration:
</p>
<ul>
<li>
<p>
<span class="STRUCTNAME">GDK_WINDOW_ROOT</span> is
the type of the GDK wrapper for the root window,
created at initialization time.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">GDK_WINDOW_TOPLEVEL</span>
is a toplevel window; the <span class="STRUCTNAME">
parent</span> argument to <tt class="FUNCTION">
gdk_window_new()</tt> should be <span class=
"STRUCTNAME">NULL</span> in this case. GDK
automatically uses the root window as the window's
parent.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">GDK_WINDOW_CHILD</span> is a
subwindow within a toplevel window.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">GDK_WINDOW_DIALOG</span> is
essentially the same as a toplevel window; its parent
should be <span class="STRUCTNAME">NULL</span> and
GDK will substitute the root window. A hint will be
set to tell the window manager the window is a
dialog; some window managers take this into
account.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">GDK_WINDOW_TEMP</span> is
used for popup menus and the like; it's a window that
will exist only briefly. It's a toplevel window, so
its parent should be <span class="STRUCTNAME">
NULL</span>. These windows are always override
redirect and their cursor is always the same as their
parent's. So they will ignore those elements of the
attributes struct.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">GDK_WINDOW_PIXMAP</span> is
not a window at all; <span class="STRUCTNAME">
GdkPixmap</span> and <span class="STRUCTNAME">
GdkWindow</span> are almost always treated the same
way, so GDK uses the same struct to represent them.
They can both be considered kinds of <span class=
"STRUCTNAME">GdkDrawable</span>. See <a href=
"sec-gdkdrawable.html">the section called <i>
Drawables and Pixmaps</i></a>.
</p>
</li>
<li>
<p>
<span class="STRUCTNAME">GDK_WINDOW_FOREIGN</span>
identifies a wrapper around a window not created by
GDK.
</p>
</li>
</ul>
<p>
Only <span class="STRUCTNAME">GDK_WINDOW_TOPLEVEL</span>,
<span class="STRUCTNAME">GDK_WINDOW_CHILD</span>, <span
class="STRUCTNAME">GDK_WINDOW_TEMP</span>, and <span
class="STRUCTNAME">GDK_WINDOW_DIALOG</span> are valid for
<tt class="FUNCTION">gdk_window_new()</tt>. Library users
may not create a <span class="STRUCTNAME">
GDK_WINDOW_ROOT</span>. Pixmaps (<span class=
"STRUCTNAME">GDK_WINDOW_PIXMAP</span>) are created with
<tt class="FUNCTION">gdk_pixmap_new()</tt>. Foreign
windows (<span class=
"STRUCTNAME">GDK_WINDOW_FOREIGN</span>) are X windows
created outside of GDK and wrapped using <tt class=
"FUNCTION">gdk_window_foreign_new()</tt> (declared in <tt
class="FILENAME">gdk/gdkx.h</tt>, since you will only
need this function if you are using Xlib directly).
</p>
<p>
The <span class="STRUCTNAME">cursor</span> field
specifies the mouse pointer (cursor) to use in this
window; see <a href="sec-gdkcursor.html">the section
called <i>The Mouse Pointer</i></a> for information about
cursors.
</p>
<p>
The "class hint" is described in <a href=
"z94.html#SEC-CLASSHINT">the section called <i>Setting
Window Class Hints</i> in the chapter called <i>The Main
Window: <tt class="CLASSNAME">GnomeApp</tt></i></a>. When
writing widgets, you will not usually set the class hint.
It is only relevant for toplevel windows; GTK+ provides
<tt class="FUNCTION">gtk_window_set_wmclass()</tt> so
application authors can set it to something sensible.
</p>
<p>
The last field in <span class="STRUCTNAME">
GdkWindowAttr</span> determines whether the window is
"override redirect." Normally, window managers intercept
all requests to show, hide, move, or resize a toplevel
window. They can then redirect or cancel these requests,
to force windows to behave according to the window
manager's layout policy. You can override this behavior
by setting <span class="STRUCTNAME">
override_redirect</span> to <span class="STRUCTNAME">
TRUE</span>. Since window managers can not move windows
with this flag set, they will normally not put a title
bar or other decorations on them. Note that all <span
class="STRUCTNAME">GDK_WINDOW_TEMP</span> windows use
<span class="STRUCTNAME">TRUE</span> for this field;
recall that <span class="STRUCTNAME">
GDK_WINDOW_TEMP</span> is often used for popup menus,
which are not controlled by the window manager.
</p>
<p>
Typically you should not change the <span class=
"STRUCTNAME">override_redirect</span> field; the default
is almost always right, if you specify the correct <span
class="STRUCTNAME">GdkWindowType</span>. However, there
are some exceptions; the Gnome panel application sets
this field, for example.
