[qooxdoo-devel] qx.ui.decoration.Background.setBackgroundPositionX(10) - proper use of

[Werner Thie]

Hi all

Is it correct that the following code DOES NOT provide the wished for 
grafical effect of shifting the background image:

var element = new qx.ui.container.Composite(new qx.ui.layout.Basic());

var decorator= new qx.ui.decoration.Background().set({
  backgroundImage : '00.png',
  backgroundRepeat: 'no-repeat',
  backgroundPositionX: 0        
});

element.setDecorator(decorator);

//later we call
element.getDecorator().setBackgroundPositionX(10);

whereas the following code DOES shift the background image:

var newDecorator= new qx.ui.decoration.Background().set({
  backgroundImage : '00.png',
  backgroundRepeat: 'no-repeat',
  backgroundPositionX: 10       
});

element.setDecorator(newDecorator);

Is the latter one the preferred method or did I overlook something?

Thxs, Werner
