Editor Creation

Hi all,

I want to create a editor in Flash that looks similar to this. I need the line numbers on the left side and the text on the right. Is this something that is possible in flash? Can someone give me some ideas to start with. I am a beginner to flash but I catch on quickly. If someone could point me in the right direction I would appreciate it. Also, if there are components that you would suggest for this I would appreciate that as well.

Thanks,

Mike B
