How to customize the button and label text size for each field separately in blackberry application? -

-

i new bb application. want customized size button text , label text.

i using code 

try {             fontfamily alphasansfamily = fontfamily.forname("bbalpha serif");             font appfont = alphasansfamily.getfont(font.plain, 9, ui.units_pt);             setfont(appfont);             } catch (classnotfoundexception e) {             }

but using change size field using within constructor.but need different size different field .like title big size , other label text button text small size.

i guessing calling when creating screen setfont() changes font full screen.

you can call set font on required button or label , change font field e.g button.setfont(yourfont)

are calling setfont() explicitly on field wish change?
