	~~TBW~~ ...		We explained in a previous topic that it is not recommended to use directly <font color=#FF8C00>swing</font> components as some mechanisms proposed by <font color=#556B2F>'''GENIUS'''</font> (as conditional display or <font color=#4169E1>before/after</font>) will not be active. Anyway, writing <font color=#4169E1>put(obj)</font> where obj is a pure <font color=#FF8C00>swing</font> object will even not compile

			So, two solutions are available if you do not dispose of the right widget :
			# to create a new high level widget using predefined <font color=#556B2F>'''GENIUS'''</font> widgets ([{{PathCurrentJavaDoc}}/fr/cnes/genius/highLevel/GComponentList.html GComponentList] was created in this way).
			# to create a basic widget a bit as [{{PathCurrentJavaDoc}}/fr/cnes/genius/lowLevel/GButton.html GButton] was developped.

			Here we are going to explain how to achieve the second solution.

			In fact, it is relatively simple ...

			== How to display the widget: ==

			First, we will have to create a new class extending [{{PathCurrentJavaDoc}}/fr/cnes/genius/main/GComponent.html GComponent] and implementing at least the [{{PathCurrentJavaDoc}}/fr/cnes/genius/main/GDisplay.html GDisplay] interface. On the following example, we will create a new class called '''GTableList''' using the <font color=#FF8C00>swing</font> widget <font color=#FF8C00>JTable</font>.

			As we extend the [{{PathCurrentJavaDoc}}/fr/cnes/genius/main/GComponent.html GComponent] class, we will have to override the <font color=#4169E1>getComponent()</font> method returning the <font color=#FF8C00>swing</font> component corresponding to the widget (here the <font color=#FF8C00>JScrollPane</font> which surrounds the <font color=#FF8C00>JTable</font>).

			Also, as we implement the [{{PathCurrentJavaDoc}}/fr/cnes/genius/main/GDisplay.html GDisplay] interface, we will also have to override the <font color=#4169E1>display()</font> method as indicated below.

			That is all ...

			<syntaxhighlight lang="java">
			public class GTableList extends GComponent implements GDisplay {

			private JTable m_JTable;
			private JScrollPane m_JScrollPane; // To get the column names displayed

			private Object[][] m_data;
			private String[] m_columnNames;

			public GTableList (Object[][] data, String[] columnNames) {

			super(null);

			m_data = data;
			m_columnNames = columnNames;
			m_JTable = new JTable(m_data, m_columnNames);
			m_JScrollPane = new JScrollPane(m_JTable);

			}

			@Override
			public void display() {
			doDisplay(this);
			}

			@Override
			public Component getComponent() {
			return m_JScrollPane;
			}

			}
			</syntaxhighlight>

			== How to catch a GENIUS event: ==

			To use the [{{PathCurrentJavaDoc}}/fr/cnes/genius/main/GListener.html GListener] interface and thus, the <font color=#4169E1>before/after</font> mechanism, we will only have to implement one of the listener used by the <font color=#FF8C00>swing</font> widget. Here we will take <font color=#FF8C00>TableModelListener</font>

			So, implementing this interface, we will have to override the <font color=#FF8C00>tableChanged()</font> method. In the following example, we will test if one of the cells have its value changed.

			<syntaxhighlight lang="java">
			public class GTableList extends GComponent implements GDisplay, TableModelListener {

			private JTable m_JTable;
			...

			@Override
			public void tableChanged(TableModelEvent e) {

			int row = e.getFirstRow();
			int column = e.getColumn();
			TableModel model = (TableModel)e.getSource();
			Object data = model.getValueAt(row, column);
			System.out.println("New data is "+data);

			GEvent gevent = new GEvent();
			processGEvent(gevent, this); // Redirection of the event !

			}

			}
			</syntaxhighlight>

			With the two last lines of code of this implementation, the <font color=#FF8C00>swing</font> event is redirected towards the <font color=#556B2F>'''GENIUS'''</font> [{{PathCurrentJavaDoc}}/fr/cnes/genius/main/GListener.html GListener]] mechanism and, in the class calling this new '''GTableList''' object, we will be able to use the <font color=#4169E1>before/after</font> methods.

			<syntaxhighlight lang="java">
			private GTableList table;

			...

			table = new GTableList(data, titles);

			...

			@Override
			public void display() throws GException {
			put(table);
			}

			...

			public void after(GEvent arg0) throws GException {

			if ( arg0.contains(table) ) {
			System.out.println("Data is modified ...");
			}

			}
			</syntaxhighlight>
