smartgwt - make window background transparent / no color

we've tried to make the background of a smartgwt window transparent with no success :/ setting a transparent image as backgroundimage yields nor directly setting a custom style class with a transparent background setting yields no开发者_JS百科 success.

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

thank you in advance, dave

I think #setOpacity(int) should do the trick... Also see #setDragOpacity(int).

I think I read that this would be a feature of the new Java JDK 7. So if you can't find an answer that might be the problem. I'm not positive though. Good Luck

I've found solution in [Showcase] - [Forms] - [Custom Picker] (SmartGWT 2.2):

Try to use code like this:

    dialog = new Dialog();
    dialog.setIsModal(true);  
    dialog.setShowModalMask(true);
    dialog.setShowHeader(false);  
    dialog.setShowEdges(false);
    dialog.setEdgeSize(10);
    dialog.setWidth(980);
    dialog.setHeight(700);  
    dialog.setShowToolbar(false);
    dialog.centerInPage();

I think this line disables background - setShowEdges(false).

Did you try #setBackgroundColor("transparent") ?

E.g.:

Window window = new Window();
window.setBackgroundColor("transparent");

Worked for me...
