<p>A <a class="link" href="gdk3-Windows.html#GdkWindow"><span class="type">GdkWindow</span></a> is a (usually) rectangular region on the screen.
Its a low-level object, used to implement high-level objects such as
<span class="type">GtkWidget</span> and <span class="type">GtkWindow</span> on the GTK+ level. A <span class="type">GtkWindow</span> is a toplevel
window, the thing a user might think of as a “window” with a titlebar
and so on; a <span class="type">GtkWindow</span> may contain many <a href="gdk3-Windows.html#GdkWindow-struct"><span class="type">GdkWindows</span></a>. For example,
each <span class="type">GtkButton</span> has a <a class="link" href="gdk3-Windows.html#GdkWindow"><span class="type">GdkWindow</span></a> associated with it.</p>
<div class="refsect2">
<a name="COMPOSITED-WINDOWS"></a><h3>Composited Windows</h3>
<p>Normally, the windowing system takes care of rendering the contents
of a child window onto its parent window. This mechanism can be
intercepted by calling <a class="link" href="gdk3-Windows.html#gdk-window-set-composited" title="gdk_window_set_composited ()"><code class="function">gdk_window_set_composited()</code></a> on the child
window. For a “composited” window it is the
responsibility of the application to render the window contents at
the right spot.</p>
</div>
<hr>
<div class="refsect2">
<a name="OFFSCREEN-WINDOWS"></a><h3>Offscreen Windows</h3>
<p>Offscreen windows are more general than composited windows, since
they allow not only to modify the rendering of the child window onto
its parent, but also to apply coordinate transformations.</p>
<p>To integrate an offscreen window into a window hierarchy, one has
to call <a class="link" href="gdk3-Windows.html#gdk-offscreen-window-set-embedder" title="gdk_offscreen_window_set_embedder ()"><code class="function">gdk_offscreen_window_set_embedder()</code></a> and handle a number of
signals. The <a class="link" href="gdk3-Windows.html#GdkWindow-pick-embedded-child" title="The “pick-embedded-child” signal"><span class="type">“pick-embedded-child”</span></a> signal on the embedder
window is used to select an offscreen child at given coordinates,
and the <a class="link" href="gdk3-Windows.html#GdkWindow-to-embedder" title="The “to-embedder” signal"><span class="type">“to-embedder”</span></a> and <a class="link" href="gdk3-Windows.html#GdkWindow-from-embedder" title="The “from-embedder” signal"><span class="type">“from-embedder”</span></a> signals
on the offscreen window are used to translate coordinates between
the embedder and the offscreen window.</p>
<p>For rendering an offscreen window onto its embedder, the contents
of the offscreen window are available as a surface, via
<a class="link" href="gdk3-Windows.html#gdk-offscreen-window-get-surface" title="gdk_offscreen_window_get_surface ()"><code class="function">gdk_offscreen_window_get_surface()</code></a>.</p>

<p>Sets a <a class="link" href="gdk3-Windows.html#GdkWindow"><span class="type">GdkWindow</span></a> as composited, or unsets it. Composited
windows do not automatically have their contents drawn to
the screen. Drawing is redirected to an offscreen buffer
and an expose event is emitted on the parent of the composited
window. It is the responsibility of the parents expose handler
to manually merge the off-screen content onto the screen in
whatever way it sees fit.</p>
<p>It only makes sense for child windows to be composited; see
<a class="link" href="gdk3-Windows.html#gdk-window-set-opacity" title="gdk_window_set_opacity ()"><code class="function">gdk_window_set_opacity()</code></a> if you need translucent toplevel
windows.</p>
<p>An additional effect of this call is that the area of this
window is no longer clipped from regions marked for
invalidation on its parent. Draws done on the parent
window are also no longer clipped by the child.</p>
<p>This call is only supported on some systems (currently,
only X11 with new enough Xcomposite and Xdamage extensions).
You must call <a class="link" href="GdkDisplay.html#gdk-display-supports-composite" title="gdk_display_supports_composite ()"><code class="function">gdk_display_supports_composite()</code></a> to check if
setting a window as composited is supported before

<p>Sets whether input to the window is passed through to the window

<p>The default value of this is <code class="literal">FALSE</code>, which means that pointer
events that happen inside the window are send first to the window,
but if the event is not selected by the event mask then the event
is sent to the parent window, and so on up the hierarchy.</p>
<p>If <em class="parameter"><code>pass_through</code></em>
is <code class="literal">TRUE</code> then such pointer events happen as if the
window wasn't there at all, and thus will be sent first to any
windows below <em class="parameter"><code>window</code></em>
. This is useful if the window is used in a
transparent fashion. In the terminology of the web this would be called
"pointer-events: none".</p>
<p>Note that a window with <em class="parameter"><code>pass_through</code></em>
<code class="literal">TRUE</code> can still have a subwindow
without pass through, so you can get events on a subset of a window. And in
that cases you would get the in-between related events such as the pointer
enter/leave events on its way to the destination window.</p>

You might use this function to implement a “window move grip,” for
example. The function works best with window managers that support the

<p>A higher value means that drawing is automatically scaled up to
a higher resolution, so any code doing drawing will automatically look
nicer. However, if you are supplying pixel-based data the scale
value can be used to determine whether to use a pixel resource
with higher resolution data.</p>

will be diverted to the
backing store. When you call <a class="link" href="gdk3-Windows.html#gdk-window-end-paint" title="gdk_window_end_paint ()"><code class="function">gdk_window_end_paint()</code></a>, the backing
store will be copied to <em class="parameter"><code>window</code></em>
, making it visible onscreen. Only
the part of <em class="parameter"><code>window</code></em>
contained in <em class="parameter"><code>region</code></em>
will be modified; that is,
drawing operations are clipped to <em class="parameter"><code>region</code></em>
.</p>
<p>The net result of all this is to remove flicker, because the user
sees the finished product appear all at once when you call
<a class="link" href="gdk3-Windows.html#gdk-window-end-paint" title="gdk_window_end_paint ()"><code class="function">gdk_window_end_paint()</code></a>. If you draw to <em class="parameter"><code>window</code></em>
directly without
calling <a class="link" href="gdk3-Windows.html#gdk-window-begin-paint-region" title="gdk_window_begin_paint_region ()"><code class="function">gdk_window_begin_paint_region()</code></a>, the user may see flicker
as individual drawing operations are performed in sequence. The
clipping and background-initializing features of
<a class="link" href="gdk3-Windows.html#gdk-window-begin-paint-region" title="gdk_window_begin_paint_region ()"><code class="function">gdk_window_begin_paint_region()</code></a> are conveniences for the
programmer, so you can avoid doing that work yourself.</p>
<p>When using GTK+, the widget system automatically places calls to
<a class="link" href="gdk3-Windows.html#gdk-window-begin-paint-region" title="gdk_window_begin_paint_region ()"><code class="function">gdk_window_begin_paint_region()</code></a> and <a class="link" href="gdk3-Windows.html#gdk-window-end-paint" title="gdk_window_end_paint ()"><code class="function">gdk_window_end_paint()</code></a> around
emissions of the expose_event signal. That is, if youre writing an
expose event handler, you can assume that the exposed area in
<a class="link" href="gdk3-Event-Structures.html#GdkEventExpose" title="struct GdkEventExpose"><span class="type">GdkEventExpose</span></a> has already been cleared to the window background,
is already set as the clip region, and already has a backing store.
Therefore in most cases, application code need not call
<a class="link" href="gdk3-Windows.html#gdk-window-begin-paint-region" title="gdk_window_begin_paint_region ()"><code class="function">gdk_window_begin_paint_region()</code></a>. (You can disable the automatic
calls around expose events on a widget-by-widget basis by calling
<code class="function">gtk_widget_set_double_buffered()</code>.)</p>
<p>If you call this function multiple times before calling the
matching <a class="link" href="gdk3-Windows.html#gdk-window-end-paint" title="gdk_window_end_paint ()"><code class="function">gdk_window_end_paint()</code></a>, the backing stores are pushed onto
a stack. <a class="link" href="gdk3-Windows.html#gdk-window-end-paint" title="gdk_window_end_paint ()"><code class="function">gdk_window_end_paint()</code></a> copies the topmost backing store
onscreen, subtracts the topmost region from all other regions in
the stack, and pops the stack. All drawing operations affect only
the topmost backing store in the stack. One matching call to
<a class="link" href="gdk3-Windows.html#gdk-window-end-paint" title="gdk_window_end_paint ()"><code class="function">gdk_window_end_paint()</code></a> is required for each call to

<div class="warning"><p><code class="literal">gdk_window_set_debug_updates</code> has been deprecated since version 3.22 and should not be used in newly-written code.</p></div>
<p>With update debugging enabled, calls to
<a class="link" href="gdk3-Windows.html#gdk-window-invalidate-region" title="gdk_window_invalidate_region ()"><code class="function">gdk_window_invalidate_region()</code></a> clear the invalidated region of the

before sending exposes to windows during
<a class="link" href="gdk3-Windows.html#gdk-window-process-updates" title="gdk_window_process_updates ()"><code class="function">gdk_window_process_updates()</code></a>. The net effect is that you can see
the invalid region for each window and watch redraws as they
occur. This allows you to diagnose inefficiencies in your application.</p>
<p>In essence, because the GDK rendering model prevents all flicker,
if you are redrawing the same region 400 times you may never
notice, aside from noticing a speed problem. Enabling update
debugging causes GTK to flicker slowly and noticeably, so you can
see exactly whats being redrawn when, in what order.</p>
<p>The --gtk-debug=updates command line option passed to GTK+ programs
enables this debug option at application startup time. That's
usually more useful than calling <a class="link" href="gdk3-Windows.html#gdk-window-set-debug-updates" title="gdk_window_set_debug_updates ()"><code class="function">gdk_window_set_debug_updates()</code></a>

<p>Sets the geometry hints for <em class="parameter"><code>window</code></em>
. Hints flagged in <em class="parameter"><code>geom_mask</code></em>
are set, hints not flagged in <em class="parameter"><code>geom_mask</code></em>
are unset.
To unset all hints, use a <em class="parameter"><code>geom_mask</code></em>
of 0 and a <em class="parameter"><code>geometry</code></em>
of <code class="literal">NULL</code>.</p>
<p>This function provides hints to the windowing system about
acceptable sizes for a toplevel window. The purpose of
this is to constrain user resizing, but the windowing system
will typically (but is not required to) also constrain the
current size of the window to the provided values and
constrain programatic resizing via <a class="link" href="gdk3-Windows.html#gdk-window-resize" title="gdk_window_resize ()"><code class="function">gdk_window_resize()</code></a> or
<a class="link" href="gdk3-Windows.html#gdk-window-move-resize" title="gdk_window_move_resize ()"><code class="function">gdk_window_move_resize()</code></a>.</p>
<p>Note that on X11, this effect has no effect on windows
of type <a class="link" href="gdk3-Windows.html#GDK-WINDOW-TEMP:CAPS"><code class="literal">GDK_WINDOW_TEMP</code></a> or windows where override redirect
has been turned on via <a class="link" href="gdk3-Windows.html#gdk-window-set-override-redirect" title="gdk_window_set_override_redirect ()"><code class="function">gdk_window_set_override_redirect()</code></a>
since these windows are not resizable by the user.</p>
<p>Since you cant count on the windowing system doing the
constraints for programmatic resizes, you should generally
call <a class="link" href="gdk3-Windows.html#gdk-window-constrain-size" title="gdk_window_constrain_size ()"><code class="function">gdk_window_constrain_size()</code></a> yourself to determine

<p>Newer GTK+ windows using client-side decorations use extra geometry
around their frames for effects like shadows and invisible borders.
Window managers that want to maximize windows or snap to edges need
to know where the extents of the actual frame lie, so that users
dont feel like windows are snapping against random invisible edges.</p>
<p>Note that this property is automatically updated by GTK+, so this
function should only be used by applications which do not use GTK+
to create toplevel windows.</p>

When an application is restarted after being saved in a previous
session, all windows with the same title and role are treated as
interchangeable. So if you have two windows with the same title
that should be distinguished for session management purposes, you
should set the role on those windows. It doesnt matter what string
you use for the role, as long as you have a different role for each
non-interchangeable kind of window.</p>

<p>The <a class="link" href="gdk3-Windows.html#GdkGeometry" title="struct GdkGeometry"><span class="type">GdkGeometry</span></a> struct gives the window manager information about
a windows geometry constraints. Normally you would set these on
the GTK+ level using <code class="function">gtk_window_set_geometry_hints()</code>. <span class="type">GtkWindow</span>
then sets the hints on the <a class="link" href="gdk3-Windows.html#GdkWindow"><span class="type">GdkWindow</span></a> it creates.</p>
<p>gdk_window_set_geometry_hints() expects the hints to be fully valid already
and simply passes them to the window manager; in contrast,
<code class="function">gtk_window_set_geometry_hints()</code> performs some interpretation. For example,
<span class="type">GtkWindow</span> will apply the hints to the geometry widget instead of the
toplevel window, if you set a geometry widget. Also, the
<em class="parameter"><code>min_width</code></em>
/<em class="parameter"><code>min_height</code></em>
/<em class="parameter"><code>max_width</code></em>
/<em class="parameter"><code>max_height</code></em>
fields may be set to -1, and
<span class="type">GtkWindow</span> will substitute the size request of the window or geometry widget.
If the minimum size hint is not provided, <span class="type">GtkWindow</span> will use its requisition
as the minimum size. If the minimum size is provided and a geometry widget is
set, <span class="type">GtkWindow</span> will take the minimum size as the minimum size of the
geometry widget rather than the entire window. The base size is treated
similarly.</p>
<p>The canonical use-case for <code class="function">gtk_window_set_geometry_hints()</code> is to get a
terminal widget to resize properly. Here, the terminal text area should be
the geometry widget; <span class="type">GtkWindow</span> 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 <em class="parameter"><code>width_inc</code></em>
and <em class="parameter"><code>height_inc</code></em>
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.</p>
<p>Heres an example of how the terminal example would be implemented, assuming
a terminal area widget called “terminal” and a toplevel window “toplevel”:</p>

<p>The other useful fields are the <em class="parameter"><code>min_aspect</code></em>
and <em class="parameter"><code>max_aspect</code></em>
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 <em class="parameter"><code>min_aspect</code></em>
and
<em class="parameter"><code>max_aspect</code></em>
to the same value, thus forcing the window to keep a constant
aspect ratio.</p>

<p>Positioning hints for aligning a window relative to a rectangle.</p>

<p>For example, <a class="link" href="gdk3-Windows.html#GDK-ANCHOR-FLIP-X:CAPS"><code class="literal">GDK_ANCHOR_FLIP_X</code></a> will replace <a class="link" href="gdk3-Windows.html#GDK-GRAVITY-NORTH-WEST:CAPS"><code class="literal">GDK_GRAVITY_NORTH_WEST</code></a> with

<p>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.</p>
<p>Like the X Window System, GDK supports 8 modifier keys and 5 mouse buttons.</p>
<p>Since 2.10, GDK recognizes which of the Meta, Super or Hyper keys are mapped
to Mod2 - Mod5, and indicates this by setting <a class="link" href="gdk3-Windows.html#GDK-SUPER-MASK:CAPS"><code class="literal">GDK_SUPER_MASK</code></a>,
<a class="link" href="gdk3-Windows.html#GDK-HYPER-MASK:CAPS"><code class="literal">GDK_HYPER_MASK</code></a> or <a class="link" href="gdk3-Windows.html#GDK-META-MASK:CAPS"><code class="literal">GDK_META_MASK</code></a> in the state field of key events.</p>
<p>Note that GDK may add internal values to events which include
reserved values such as <a class="link" href="gdk3-Windows.html#GDK-MODIFIER-RESERVED-13-MASK:CAPS"><code class="literal">GDK_MODIFIER_RESERVED_13_MASK</code></a>. Your code
should preserve and ignore them. You can use <a class="link" href="gdk3-Windows.html#GDK-MODIFIER-MASK:CAPS"><code class="literal">GDK_MODIFIER_MASK</code></a> to
remove all reserved values.</p>
<p>Also note that the GDK X backend interprets button press events for button
4-7 as scroll events, so <a class="link" href="gdk3-Windows.html#GDK-BUTTON4-MASK:CAPS"><code class="literal">GDK_BUTTON4_MASK</code></a> and <a class="link" href="gdk3-Windows.html#GDK-BUTTON5-MASK:CAPS"><code class="literal">GDK_BUTTON5_MASK</code></a> will never
