problem in LayoutContainer alignment

[poporogue]

Hi
I have written a GXT application and i want to place the gxt object with center alignment in the browser.
However, i have tried with setStyleAttribute, it fails.
Then i set the style name to the container and do it in the css file included in the html, it fails too.

So what can i do to make it center?

Here is my simple code.

LayoutContainer container = new LayoutContainer();        
 container.setStyleAttribute("margin", "10px");
container.setLayout(new FlowLayout());
container.setSize(800, 600);
container.setBorders(true);
container.setStyleName("formPainter_main");

RootPanel.get().add(container);

Thanks

How do you want to center it? Your code does not contain any logic to center it. Which rules do "formPainter_main" assign to it?
