Hi. I need to know the size of the screen because I'm using a popup panel and I want its width to be the 90% of total width.
I've been looking for something on the touch API and i've tried with some "Ext.Element" methods like: Ext.Element.getOuterWidth()*0.9, Ext.Element.getViewportWidth()*0.9 , Ext.Element.getWidth()*0.9
I think I'm not looking in the right place.
Can anyone help? Thanks.
