Re: [ jEdit-users ] OS X issues: scroll, memory, php?

[Bjorn W. <mai...@bd...>]

Hi all,

Thanks for all info and advice!

Upon Slava's advice I have tried the 4.3pre2 version. I made sure to 
rename my .jedit user dir so the 4.3 version could start with a clean 
slate. I removed all plugins (thanks Steve), for testing 4.3 and 4.2.

It feels 4.3 is somewhat better than the 4.2 scrolling, although its not 
perfect (yet). The removal of the plugins had only the expected effect 
of Jedit starting up more quickly. I also noticed that the steps JEdit 
takes seem to be quit large and in percentages -in my case around 5%- on 
average. This seems to be in contradiction with somekind of 'smoothness' 
if you know what I mean. At a co-worker's mac the same scrolling 
problems as mine are there and he has the same problems with it. That's 
another reason for me in trying to fix it. I will try to test Jedit on 
some different macs and see what the results are for 4.2 and 4.3.

I know scrolling seems such a minor issue, but for someone that is using 
JEdit as my main tool this minor annoyance is becoming something that 
evolves into frustration with using Jedit.

As for the issues with Java being not fast or small -I can live with 
that- but there are other Java apps that seem more responsive such as 
Cyberduck (ftp client) which I also use. I guess the advice for better 
hardware and OS is a joke, because I can't imagine saying that as a 
solution to someone ;)

Has anyone had the time to see if the same kind of haviour that 
SmoothWheel delivers for Firefox can be used for Jedit? I have no 
experience in developing Java applications, but I'm willing to help 
out...just let me know what I can do to make life easier for you guys in 
solving this issue. Maybe it is possible to generate somekind of 
logoutput so I can 'show' the kind of cursor movement I now get. So you 
guys can (re)view it? Optional I can try to create some kind of 
screencapture?

I hope I can contribute into making JEdit THE editor and by solving this 
issue I would feel JEdit would be well on its way.

grtz
