<a name="libgda-5.0-GdauiDataEntry.description"></a><h2>Description</h2>
<p>The <span class="type">GdaUiDataEntry</span> is an interface for widgets (simple or complex)
which lets the user view and/or modify a <a href="/usr/share/gtk-doc/html/gobject/gobject-Generic-values.html#GValue"><span class="type">GValue</span></a>.</p>
<p>This interface is implemented by widgets which feature data editing (usually composed of an editing
area and a button to have some more control on the value being edited).
The interface allows to control how the widget works and to query the value and the attributes
of the data held by the widget.</p>
<p>The widget can store the original value (to be able to tell if the value has been changed
by the user) and a default value (which will be returned if the user explicitly forces the widget
to be set to the default value).
Control methods allow to set the type of value to be edited (the requested type must be
compatible with what the widget can handle), set the value (which replaces the currently edited
value), set the value and the original value (the value passed as argument is set and is also
considered to be the original value).</p>
<p><span class="type">GdaUiDataEntry</span> widgets are normally created using the <a class="link" href="libgda-5.0-UI-Utility-functions.html#gdaui-new-data-entry" title="gdaui_new_data_entry ()"><code class="function">gdaui_new_data_entry()</code></a> function.</p>
