Re: the output of DialogBox is very strange

What would you expect to see? It looks like you're missing a call to
DialogBox.setWidget. You're not telling the DialogBox what to display.

By the way, you don't have to subclass DialogBox for very simple
cases:

DialogBox dialogBox = new DialogBox(false, true); // or any other
values for autohide/modal
dialogBox.setText(getMyCaption());
dialogBox.setWidget(getMyContentWidget());
dialogBox.setSize("1000px", "800px");
dialogBox.setGlassEnabled(true);
dialogBox.setAnimationEnabled(true);
dialogBox.show();

Hope this helps,
Ralf
