<p>
<a class="link" href="InfAdoptedUndoGrouping.html" title="InfAdoptedUndoGrouping"><span class="type">InfAdoptedUndoGrouping</span></a> groups related requests together so that they can
be undone at the same time. For example, Undo in a text editor is normally
expected to operate on written words, not characters. Therefore, multiple
requests need to be undone at once.
</p>
<p>
The undo grouping helps with this. Everytime it needs to decide whether two
requests should be grouped it emits
<a class="link" href="InfAdoptedUndoGrouping.html#InfAdoptedUndoGrouping-group-requests" title='The "group-requests" signal'><span class="type">"group-requests"</span></a>. If the signal handler returns
<code class="literal">TRUE</code> then the two requests will be undone at the same time, otherwise not.
</p>
<p>
It is also possible to explicitely group a bunch of requests that would
not be grouped otherwise, by calling <a class="link" href="InfAdoptedUndoGrouping.html#inf-adopted-undo-grouping-start-group" title="inf_adopted_undo_grouping_start_group ()"><code class="function">inf_adopted_undo_grouping_start_group()</code></a>
and <a class="link" href="InfAdoptedUndoGrouping.html#inf-adopted-undo-grouping-end-group" title="inf_adopted_undo_grouping_end_group ()"><code class="function">inf_adopted_undo_grouping_end_group()</code></a> before and after issuing the
requests, respectively.
</p>
<p>
The default signal handler always returns <code class="literal">FALSE</code>. However, this behaviour
can be changed in derived classes.

<pre class="programlisting"><span class="returnvalue">gboolean</span> user_function (<a class="link" href="InfAdoptedUndoGrouping.html" title="InfAdoptedUndoGrouping"><span class="type">InfAdoptedUndoGrouping</span></a> *grouping,

<p>
This signal is emitted whenever the <a class="link" href="InfAdoptedUndoGrouping.html" title="InfAdoptedUndoGrouping"><span class="type">InfAdoptedUndoGrouping</span></a> needs to
decide whether to put two requests into the same undo group or not.
A signal handler should return <code class="literal">TRUE</code> if they belong into the same group
or <code class="literal">FALSE</code> otherwise. Note however that the two requests may not
immediately follow each other because other users may have issued
requests inbetween. Check the vector times of the requests to find out,
using <a class="link" href="InfAdoptedRequest.html#inf-adopted-request-get-vector" title="inf_adopted_request_get_vector ()"><code class="function">inf_adopted_request_get_vector()</code></a>.
