Hello,

When JdbNavToolBar is resized smaller to certain extend, it doesn't
re-layout itself.  The images go upward that only the lower parts of the
images can be seen, and the texts are squeezed to "..." only.  

I'd like to ask:

1. how can I re-layout the internal buttons of JdbNavToolBar?  
I tried doLayout(), updateUI(), setSize()... I still can't handle to do
this.

2. how can I show only the images of buttons in a JdbNavToolBar instead
of images + texts?

Thank you so much in advance.
