<h3>e955. Setting the Activation Click Count for a Table Cell Editor in a JTable Component</h3>
By default, a table cell editor is activated with a double-click. The
activation behavior is controlled by the renderer, not by a table
property. To change this, override the <code>isCellEditable()</code> method of the
editor. See <a href="../javax.swing.table/CustEdit.html" class="eglink"><b>e953</b> Creating a Custom Table Cell Editor in a JTable Component</a> for more
information about table cell editors.
<pre>
public class MyTableCellEditor extends AbstractCellEditor implements TableCellEditor {
// See <a href="../javax.swing.table/CustEdit.html" class="eglink"><b>e953</b> Creating a Custom Table Cell Editor in a JTable Component</a>
// for other methods that need to be implemented.
public boolean isCellEditable(EventObject evt) {
if (evt instanceof MouseEvent) {
int clickCount;
// For single-click activation
clickCount = 1;
// For double-click activation
clickCount = 2;
// For triple-click activation
clickCount = 3;
return ((MouseEvent)evt).getClickCount() >= clickCount;
}
return true;
}
}
