To change the font of the title bar of a JInternalFrame,
there is no 'general' way to do this.
With Windows L&F,
   you should use UIManager.put("InternalFrame.titleFont", font)
With Metal L&F
   you should use UIManager.put("InternalFrame.font", font)
With Motif L&F
   don't find what to do ...

Please , may we have consistent way to modify a L&F!

  Bug description :
 While enlarging JInternalFrame's title font size, I notice that the title
 apperance and the key (as used by UIManager.put(..)) it respond to
 is inconsistent between different look and feel.
 
 I'm using javax.swing.UIManager's put() method to set
 JInternalFrame's title font.
 
 JInternalFrame's title, while in cross platform look and feel, respond
 to the key : "InternalFrame.font" instead of "InternalFrame.titleFont".
 
 However, in windows look and feel, JInternalFrame's title respond
 correctly to "InternalFrame.titleFont" - however the title's height area is
 not correctly aligned, causing part of the enlarged title chopped off.
 
 JInternalFrame's title does not respond to either key while in
 Motif's look and feel.
 
 I need to enlarge the title font size for JInternalFrame (as well as for
 other components) as I operate in 1024x768 (or higher) resolution.
