I am changing a program written in a older version to the 1.4 version
when i used -deprecation I had to change the handleEvent to processEvent. Now i have a problem.
I want to capture int value in xPos and yPos but I am getting an erorr.
Could any one pls tell me where I am going wrong and how to correct it??

I don't know what 'arg' is. It is certainly not a field of AWTEvent in 1.3.1.
How about trying

The same method would wok if you wanted to use Swing JScrollBars instead, just the cast would be different.
