  80
  81                 <h1>Developer's HOWTO:<br />making Your own GUI for mDictionary (old versien of mDictionary)</h1>
  82
  83 <p><b>mDictionary</b> is intended to be as modifiable as possible. So apart from developing Your own dictionary engines, You can also create alternative user interface, should You find ours inattractive. For the intrepid ones, I have described how to do that. In this howto, I am going to explain how to communicate GUI with the engines's manager</p>
  84
  85 <p>The only header file You need to include in Your GUI is <span class="code">ws_dbus.h</span>. It contains all the functions necessary to communicate with the engines manager. The header file is available from our svn repository at <a href="https://garage.maemo.org">https://garage.maemo.org</a>.</p>
  86 <p>Firstly, You initialize our dbus wrapper library with <span class="code">ws_dbus_create</span> function. You have to specify the name and the version of Your app and store the function's return value as it is necessary for further dbus wrapper communication.</p>
  87
  88 <div class="code">dbus_data = ws_dbus_create ("mDictionaryGui", "v1.0");</div>
  89 <p>
  90
  91 </p>
  92 <div class="code">ws_dbus_config( dbus_data,
  93                 WS_DBUS_CONFIG_SERVICE,
  94                 "org.maemo.mDictionaryGui" );
  95 ws_dbus_config( dbus_data,
  96                 WS_DBUS_CONFIG_OBJECT,
  97                 "/org/maemo/mDictionaryGui" );
  98 ws_dbus_config( dbus_data,
  99                 WS_DBUS_CONFIG_IFACE,
 100                 "org.maemo.mDictionaryGui" );
 101 ws_dbus_config( dbus_data,
 102                 WS_DBUS_CONFIG_REMOTE_SERVICE,
 103                 "org.maemo.mDictionaryManager" );
 104 ws_dbus_config( dbus_data,
 105                 WS_DBUS_CONFIG_REMOTE_OBJECT,
 106                 "/org/maemo/mDictionaryManager" );
 107 ws_dbus_config( dbus_data,
 108                 WS_DBUS_CONFIG_REMOTE_IFACE,
 109                 "org.maemo.mDictionaryManager" );</div>
 110 <p>
 111 Now You have to call the <span class="code">ws_dbus_connect</span> function. It's an opaque function, which allows local methods to be run remotely.
 112 </p>
 113 <div class="code">ws_dbus_connect( dbus_data );</div>
 114 <p>
 115 The only thing that's left now is specifying callback functions (with <span class="code">ws_dbus_set_cb</span>), which are to be called
 116 whenever the manager calls a remote method.
 117 </p>
 118 <div class="code">ws_dbus_set_cb( dbus_data,
 119                 "return_words",
 120                 ws_gui_dbus_return_words,
 121                 ws_gui_app );</div>

 134 In this case, words is a <span class="code">GArray</span> of <span class="code">osso_rpc_t</span> values. To access the contents of an <span class="code">osso_rpc_t</span> variable, You first have to check its type by accessing the type field. The value field is an union of primitives. Depending on the type, You should read the value by accessing a proper field. Here is an example:
 135 </p>
 136
 137 <div class="code">int i;
 138 osso_rpc_t data;
 139 for (i = 0; i < words->len; ++i)
 140 {
 141         data = g_array_index (words, osso_rpc_t, 0);
 142         if (DBUS_TYPE_STRING == data.type)
 143         {
 144                 char *tmp_word = g_strdup(data.value.s);
 145                 do_sth_with_word(tmp_word);

 153 <p>
 154 All functions containing the word client in their name, should be called from the GUI application.
