🚀 go-pugleaf

Sounds like your subclassing another visual component... JBuilder doesn't
support Visual Form inheritance. e.g.

class A subclasses JFrame

class B subclasses A

YOU will get a red box if you try to visually design class B in JB.

WORKAROUND:

I simply leave two sets of code at the top of the class definition for class B
e.g.:

class B subclasses A
//class B subclasses JFrame

Uncomment the 2nd line and comment the 1st line any time you want to visually
design B - once your done reverse the comments back to the above.

HTH.
