java - smartgwt - make window background transparent / no color -

-

we've tried make background of smartgwt window transparent no success :/ setting transparent image backgroundimage yields nor directly setting custom style class transparent background setting yields no success.

is there possibility change default background color : #ffffff or rgb(255,255,255) transparent?

thank in advance, dave

i think #setopacity(int) should trick... see #setdragopacity(int).
