Using inheritance, you can extend DockLayoutPanel class and write an accessor to LayoutData, or just write a boolean method which tells if widget x is hidden or not.

I think you can find something like this:

String visibility = myDockLayoutPanel.getWidgetContainerElement(childPanel).getStyle().getVisibility()

The visibility might be "visible | hidden | collapse | inherit"
