Change Color on IOConsoleOutputStream [message #290289]

I am writing a terminal emulator in a plugin and have the basics
working. I now want to recognize escape commands that change the text
color. I have an OutputStream that wraps IOConsoleOutputStream and on a
write it parses the escape sequences but I get an error when calling the
method setColor on the IOConsoleOutputStream. Is there a better way to
do this?

I also have a problem with the cursor not following the end of written
text. When a letter is typed the cursor does travel to the end of text.

You need to call setColor(..) from the UI thread. Calling from any other
thread would likely cause an invalid thread access error.

I wish I could help you with your particular problem, I can't, but I am dying to know what you based your terminal emulation code on? I wrote a simple terminal window for an application in Eclipse once, and I think I used the JTerm source as a model? I remember that the code was a fraking nightmare and I don't remember too many good open source java curses libraries.

Thanks,
