<title>Description</title>
<para>A <link
linkend="class-gdkrectangle"><classname>gtk.gdk.Rectangle</classname></link>
holds the position and size of a rectangle. The position is specified by the
"x" and "y" attributes and the size, by the "width" and "height"
attributes.</para>
<para>
Starting with PyGTK 2.14 <classname>gtk.gdk.Rectangle</classname> objects are
properly comparable. By Python rules, rectangles (being mutable) are now
unhashable. If you need to use them as dictionary keys, convert rectangle objects
to tuples first. You can convert such tuples back
to <classname>gtk.gdk.Rectangle</classname> using the following code:
</para>
<programlisting>
rectangle = gtk.gdk.Rectangle(*tuple)
</programlisting>
<para>
Also beginning with PyGTK 2.14 <classname>gtk.gdk.Rectangle</classname> objects have
custom support for <function>repr</function> Python function. For any rectangle it
holds that:
</para>
<programlisting>
rectangle == eval(repr(rectangle))
</programlisting>
