I'm essentialy trying to create an app that acts as a debugger for a different programming language, FORTRAN to be specific. Feel free to suggest a different route for this if you can think of one, but downloading a separate program to do this is not an option due to certain restrictions. I want to have a text area where a script can be edited, and have a checkbox or some clickable UI component next to each line that I can use to insert breakpoints, just like the MATLAB script editor interface.
I tried including a List Box next to the script area, but I couldn't get the line spacing to match up. I tried including a Text Area with a hyperlink on each line, but it doesn't look like hyperlinks are possible. I could try programatically inserting a checkbox next to each line, but the alignment needs to be perfect and the line spacing of a Text Box seems to change between the editor and the launched app, so I feel like that would be an error-prone solution. It's important that the script area perform just like a normal text editor, so I'd rather avoid using a List Box workaround or something similar.
