Since GWT is clearly moving away from (deprecating) TabPanel, let's ween ourselves off of it. However, TabLayoutPanel is a RequiresResize widget, which means it's not a drop-in replacement; it needs to be part of a layout.

The easiest way to accomplish this, if you have a degree of control over your page, is with something like:

    RootLayoutPanel.get().add(new ConfigEditorPanel(barHeight));
