<li class="listitem"><p><a class="link" href="GtkDataEntry.html#GtkDataEntry--description" title="The “description” property"><span class="type">“description”</span></a> - no functionality, a place for
private information that cannot be put anywhere else</p></li>
<li class="listitem"><p><a class="link" href="GtkDataEntry.html#GtkDataEntry--datatype" title="The “datatype” property"><span class="type">“datatype”</span></a> - no functionality, a datatype hint
for the application because any widget content is text</p></li>
<li class="listitem"><p><a class="link" href="GtkDataEntry.html#GtkDataEntry--dataformat" title="The “dataformat” property"><span class="type">“dataformat”</span></a> - a formatting instruction that
controls what you see when the widget doesn't have input
focus</p></li>
<li class="listitem"><p><a class="link" href="GtkDataEntry.html#GtkDataEntry--text" title="The “text” property"><span class="type">“text”</span></a> - set the contents of the widget. if the
widget doesn't have input focus text will be formatted
according to the data_format</p></li>
<li class="listitem"><p><a class="link" href="GtkDataEntry.html#GtkDataEntry--max-length-bytes" title="The “max-length-bytes” property"><span class="type">“max-length-bytes”</span></a> - set the maximum byte
length for the contents of the widget.</p></li>
</ul></div>
<p>The main reason for this widget is to provide a formatting
entry widget for numeric data like integer, float, money
which also supports NULL values (GtkSpinButton is nice but
doesn't support empty field values). Handling of Null values
is supported by all SQL database systems. The Null values are
represented by empty field contents. </p>
<p>When editing field contents, all data formatting is removed
before the focus enters the widget. As soon as the focus
leaves the widget, data will be nicely formatted again. </p>
<p>As an additional feature, the minus sign (negative numbers)
can be entered at the end of the data. As soon as you leave
the field it will be placed properly in front of the number. </p>
