</p><ul><li> A
backing store (offscreen buffer) large enough to contain <code>region</code> will be
created. The backing store will be initialized with the background color or
background pixmap for <code>DrawWindow</code>. Then, all drawing operations performed on
<code>DrawWindow</code> will be diverted to the backing store. When you call
<code><a href="Graphics-UI-Gtk-Gdk-DrawWindow.html#v:drawWindowEndPaint">drawWindowEndPaint</a></code>, the backing store will be copied to <code>DrawWindow</code>, making it
visible onscreen. Only the part of <code>DrawWindow</code> contained in <code>region</code> will be
modified; that is, drawing operations are clipped to <code>region</code>.
</li></ul><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 <code><a href="Graphics-UI-Gtk-Gdk-DrawWindow.html#v:drawWindowEndPaint">drawWindowEndPaint</a></code>. If
you draw to <code>DrawWindow</code> directly without calling <code><a href="Graphics-UI-Gtk-Gdk-DrawWindow.html#v:drawWindowBeginPaintRegion">drawWindowBeginPaintRegion</a></code>, the
user may see flicker as individual drawing operations are performed in
sequence. The clipping and background-initializing features of
<code><a href="Graphics-UI-Gtk-Gdk-DrawWindow.html#v:drawWindowBeginPaintRegion">drawWindowBeginPaintRegion</a></code> 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

<code>expose_event</code> signal. That is, if you're writing an expose event handler,
you can assume that the exposed area in <code><a href="Graphics-UI-Gtk-Gdk-EventM.html#v:eventRegion">eventRegion</a></code> 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 <code><a href="Graphics-UI-Gtk-Gdk-DrawWindow.html#v:drawWindowBeginPaintRegion">drawWindowBeginPaintRegion</a></code>. (You can disable the automatic calls
around expose events on a widget-by-widget basis by calling
<code><a href="Graphics-UI-Gtk-Abstract-Widget.html#v:widgetSetDoubleBuffered">widgetSetDoubleBuffered</a></code>.)
</p><p>If you call this function multiple times before calling the matching
<code><a href="Graphics-UI-Gtk-Gdk-DrawWindow.html#v:drawWindowEndPaint">drawWindowEndPaint</a></code>, the backing stores are pushed onto a stack.
<code><a href="Graphics-UI-Gtk-Gdk-DrawWindow.html#v:drawWindowEndPaint">drawWindowEndPaint</a></code> 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 <code><a href="Graphics-UI-Gtk-Gdk-DrawWindow.html#v:drawWindowEndPaint">drawWindowEndPaint</a></code> is required for each call to
