I want to build a J form which is essentially a session manager. In other words, the user will type in a line of text. The line will be appended to the session. An application function will process the line. The result will be appended to the session.
Sessions can be large (hundreds of megabytes, worst case), but usually only the tail end of the session is of interest. Sessions will be logged to a file. Advanced versions may color the text (input a different color from ouput, for example). How to implement? One approach has a richeditm which represents the entire session. This incurs tremendous cost updating the session when the session gets large. I'm rejecting this as unworkable. One approach has a richeditm which represents the visible part of the session. A scroll bar would allow navigation within the session. Arrow keys could not be used for scrolling (no J event handler for them). Mouse wheel could not be used for scrolling (no J event handler for it). Any better approaches?
