Hello, i have a big problem...
I have two classes:
socketIRC (java pure class)
guiControl (cocoa - java...instanced from IB)
GuiControl have one outlet and one action:
NSTextField label;
OpenConnection();
I would to set a string value to label (.setStringValue()) from class
socketIRC (i have instanced this class inside the guicontrol class from
the openconnection method) to the guiControl class.
I have tried to do it but an error like this: "non static context...".
Now i set the NSTextField to public static. But another error, this time
at the runtime. When i try to set the value:
"java.lang.NullPointerException".
Now my question is: how can i set a value of an object inside a class,
from another class?
And... my socketIRC class have a while(1) (until the end of execution)
that read the socket buffer for new data incoming. But if i try to run
the class, i can't do anything more... how can i run this process in
background? (i have instanced the object: socketIRC x = new socketIRC();
x.main();).
Thx a lot, malcom
