Re: [Tm4j-tmnav-dev] running tmnav on applet

Hi Rinalldo
You also need to call show() in TMNav. (Its not good design that this
mathod does initilisation stuff :().
And you probably need to comment out line 170 of TMNav where
TMNavMainFrame.show() is called.
After commented out, try this:
TMNav app = TMNav.getInstance();
app.show();
TMNavMainFrame frame = app.getFrame();
frame.show();
Hope that helps
