<p>The <a class="link" href="GdauiDataSelector.html" title="GdauiDataSelector"><span class="type">GdauiDataSelector</span></a> interface is implemented by widgets which allow the user
to select some data from a <a class="link" href="GdaDataModel.html" title="GdaDataModel"><span class="type">GdaDataModel</span></a>. Depending on the actual widget, the selection
can be a single row or more than one row.</p>
<p>This interface allows one to set and get the <a class="link" href="GdaDataModel.html" title="GdaDataModel"><span class="type">GdaDataModel</span></a> from which data is to be selected
and offers a few other common behaviours.</p>
<p>Please note that any row number in this interface is in reference to the <a class="link" href="GdaDataModel.html" title="GdaDataModel"><span class="type">GdaDataModel</span></a> returned by
the <a class="link" href="GdauiDataSelector.html#gdaui-data-selector-get-model" title="gdaui_data_selector_get_model ()"><code class="function">gdaui_data_selector_get_model()</code></a> method.</p>
