Questions for Java Gurus
There were a few things about Java I was unable to figure out on
my own.
(Some of the questions are more about Netscape, but have to do with
how Java behaves in Netscape.)
If you can provide me with the answer to any of these
questions, I would appreciate it if you would send me
email.
- Why is drawing so slow in backing or direct mode in JDK?
It takes about 8 times as long to draw in backing or direct mode
as in synchronous mode. Fortunately, Netscape doesn't seem to
suffer from this problem.
- The Stop button in Netscape doesn't behave quite as expected:
when pressed, the applet does not stop until the pointer is moved
out of the Stop button. Why is this? Is there a way to make it
stop right away?
- How can I draw lines greater than one pixel wide?
- How can I make the screen layout correctly when adding/removing wheels?
I've tried calling layout() on the parents, but that doesn't seem
to do the trick.
- How can I ring the bell, for devices with no sound card?
I'm looking for the equivalent of XBeep().
- In Netscape, is there a way to let the user change security to
allow load/save files?
