I've been trying to align the content of a WContainerWidget both horizontally and vertically. The horizontal is no problem. I can't seem to make the vertical alignment work though. For example:

final WContainerWidget main = new WContainerWidget();
main.setContentAlignment(AlignmentFlag.AlignCenter,AlignmentFlag.AlignMiddle);
main.addWidget(createTitleWidget(name));
main.setWidth(new WLength(300));
main.setHeight(new WLength(100));

I've tried various approaches. But still the content is alligned vertically to the top. Is this the way it should work ? Or am I missing something here ?

TIA !!!
