 *	A button is a control that contains a text string,
 *	and is one of the commonest elements of a GUI. It may 
 *	be placed on a dialog box or panel, or indeed almost any other window.
 *  An example:
 *  <pre><code class="whjs">// dlg is a wxDialog
 *  var button = new wxButton(dlg, -1, "Click me");
 *  button.onClicked = function(event)
 *  {
 *    wxMessageBox("You've clicked me");
