communication between two JInternalFrames

[javaSweden]

I could not figure out how to send information from one JinternalFrame to another (when using different classes). I attach a simple example to illustrate my problem:

I have one main class (MyInternalFrame13Aug) and two other classes that extends JInternalFrame class - InternalFrameA and InternalFrameB.

I simply want to send a textstring generated from a JTextField in class InternalFrameA to the JTextField in class InternalFrameB. But the textstring from InternalFrameA does not show up in the other class - despite there is a relation between InternalFrameA and InternalFrameB.



Would be very glad if someone could solve this problem.

You didn't bother to reply to 3 responses on your earlier thread. Why should we expect any better behavior this time round?

Thanks Darryl for the warning.
