<tr><td colspan="2"><p><a class="anchor" id="amgrp166ee6d4a07099967f73843ae890d3cf"></a> These are the predefined symbols that are used as the <code>COMMAND</code> argument of callback functions of an input method driver (see <a class="el" href="structMInputDriver.html#a159fe7401cd0913dc8c480a18efeff64" title="List of callback functions.">MInputDriver::callback_list</a>).</p>
<p>Most of them do not require extra argument nor return any value; exceptions are these:</p>
<p><b>Minput_get_surrounding_text:</b> When a callback function assigned for this command is called, the first element of <a class="el" href="structMInputContext.html#a12f494b6550e5ec675c187766fb9e461">MInputContext::plist</a> has key <a class="el" href="group__m17nPlist.html#ga0ce08eb57aa339db4d4745e75e80fdd8" title="Symbol whose name is "integer".">Minteger</a> and the value specifies which portion of the surrounding text should be retrieved. If the value is positive, it specifies the number of characters following the current cursor position. If the value is negative, the absolute value specifies the number of characters preceding the current cursor position. If the value is zero, it means that the caller just wants to know if the surrounding text is currently supported or not.</p>
<p>If the surrounding text is currently supported, the callback function must set the key of this element to <a class="el" href="group__m17nPlist.html#ga1a22859374071a0ca66f12452afee8bd" title="Symbol whose name is "mtext".">Mtext</a> and the value to the retrieved M-text. The length of the M-text may be shorter than the requested number of characters, if the available text is not that long. The length can be zero in the worst case. Or, the length may be longer if an application thinks it is more efficient to return that length.</p>
<p>If the surrounding text is not currently supported, the callback function should return without changing the first element of <a class="el" href="structMInputContext.html#a12f494b6550e5ec675c187766fb9e461">MInputContext::plist</a>.</p>
<p><b>Minput_delete_surrounding_text:</b> When a callback function assigned for this command is called, the first element of <a class="el" href="structMInputContext.html#a12f494b6550e5ec675c187766fb9e461">MInputContext::plist</a> has key <a class="el" href="group__m17nPlist.html#ga0ce08eb57aa339db4d4745e75e80fdd8" title="Symbol whose name is "integer".">Minteger</a> and the value specifies which portion of the surrounding text should be deleted in the same way as the case of Minput_get_surrounding_text. The callback function must delete the specified text. It should not alter <a class="el" href="structMInputContext.html#a12f494b6550e5ec675c187766fb9e461">MInputContext::plist</a>. </p>

<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>API for Input method. </p>
<p>An input method is an object to enable inputting various characters. An input method is identified by a pair of symbols, LANGUAGE and NAME. This pair decides an input method driver of the input method. An input method driver is a set of functions for handling the input method. There are two kinds of input methods; internal one and foreign one.</p>
<ul>
<li>
<p class="startli">Internal Input Method</p>
<p>An internal input method has non <code>Mnil</code> LANGUAGE, and its body is defined in the m17n database by the tag <Minput_method, LANGUAGE, NAME>. For this kind of input methods, the m17n library uses two predefined input method drivers, one for CUI use and the other for GUI use. Those drivers utilize the input processing engine provided by the m17n library itself. The m17n database may provide input methods that are not limited to a specific language. The database uses <code>Mt</code> as LANGUAGE of those input methods.</p>
<p>An internal input method accepts an input key which is a symbol associated with an input event. As there is no way for the <code>m17n</code> <code>library</code> to know how input events are represented in an application program, an application programmer has to convert an input event to an input key by himself. See the documentation of the function <a class="el" href="group__m17nInputMethodWin.html#ga58715c630a04fd33f12394e9c93f1bad" title="Convert an event to an input key.">minput_event_to_key()</a> for the detail.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">Foreign Input Method <a class="anchor" id="foreign-input-method"></a></p>
<p>A foreign input method has <code>Mnil</code> LANGUAGE, and its body is defined in an external resource (e.g. XIM of X Window System). For this kind of input methods, the symbol NAME must have a property of key <a class="el" href="group__m17nInputMethod.html#gaf03ec92f0d20d9bff8b9031461270d41">Minput_driver</a>, and the value must be a pointer to an input method driver. Therefore, by preparing a proper driver, any kind of input method can be treated in the framework of the <code>m17n</code> <code>library</code>.</p>
<p>For convenience, the m17n-X library provides an input method driver that enables the input style of OverTheSpot for XIM, and stores <a class="el" href="group__m17nInputMethod.html#gaf03ec92f0d20d9bff8b9031461270d41">Minput_driver</a> property of the symbol <code>Mxim</code> with a pointer to the driver. See the documentation of m17n GUI API for the detail.</p>
<p class="endli"></p>
</li>
</ul>
<p>PROCESSING FLOW</p>
<p>The typical processing flow of handling an input method is:</p>
<ul>
<li>open an input method </li>
<li>create an input context for the input method </li>
<li>filter an input key </li>
<li>look up a produced text in the input context </li>
</ul>
