</h1><div class="doc"><p>All drawing operations in Gdk take a graphics context (GC) argument. A
graphics context encapsulates information about the way things are drawn,
such as the foreground color or line width. By using graphics contexts, the
number of arguments to each drawing call is greatly reduced, and
communication overhead is minimized, since identical arguments do not need
to be passed repeatedly.
</p><p>Most values of a graphics context can be set at creation time by using
<code><a href="Graphics-UI-Gtk-Gdk-GC.html#v:gcNewWithValues">gcNewWithValues</a></code>. A few of the values in the GC, such as the dash
pattern, can only be set by the latter method.
