[Chameleon] button within a widget

You can easily do this ... the steps are (roughly):

* include the button code:

include_once( dirname(__FILE__)."/../Button.php" );

* add a class member variable to hold the button object:

class myWidget extends CWCWidget
var $moButton = null;

* In the constructor of your widget:

$this->moButton = new CWCButton( $this );

* In InitDefaults:

$this->moButton->SetOnClick( 'myWidgetFunction' );

You will need to call all the functions that CWCButton uses, check 
Button.php to see which ones they are.  In general, it will be

function GetJavascriptIncludes()
     $aReturn = $this->moButton->GetJavascriptIncludes();

     //your includes

     return $aReturn;

there are several of these ... you need them ALL even if you don't do 
anything in the functions other than call the button function and return 
the resulting array.

in DrawPublish() you can now do:

$szButton = $this->moButton->DrawPublish();

and then incorporate $szButton into your output that gets returned from 

The button will call myWidgetFunction( ) when clicked.  myWidgetFunction 
will receive the button object as the first parameter, then any other 
parameters you supplied (see Button.php to pass other parameters, its 
not usually necessary)
