I am extending the java.awt.Scrollbar class to enable the user to
change more than just the position of the scrollbar. I wish to update
some fields in the main applet and thus have created a calculate()
method in my main applet.
I pass a refrence *Calc) to the applet in the scrollbar constructor,
but get this error message when I try to call calculate:
C:\html\classes>c:\jdk2\java\bin\javac slider.java
slider.java:68: Can't make static reference to method void calculate()
in class
Calc.
Calc.calculate();
^
Can anyone: 1. Exlpain this problem -- Why can't I do this?
2. Suggest a method by which I can trigger an updating
method in the applet class.
Thanks,
-- Mike
