<a name="IBusKeymap.description"></a><h2>Description</h2>
<p>An IBusKeymap defines the mapping between keyboard scancodes and
keyboard symbols such as numbers, alphabets, and punctuation marks.</p>
<p>Some input methods assume certain keyboard layout
(such as Chewing and Wubi requires an US-QWERTY layout),
and expect key symbols to be arranged in that order.
These input methods should new an IBusKeymap
instance and define the keyboard layout.
Then <a class="link" href="IBusKeymap.html#ibus-keymap-lookup-keysym" title="ibus_keymap_lookup_keysym ()"><code class="function">ibus_keymap_lookup_keysym()</code></a> can
convert scancodes back to the key symbols.</p>
