How to open txt file in a new xCode file

Hello guys!
i´ve a folder populate with .txt files. and i have a ListBox to acces them. What i want is to make a double click and open the file in a xcode tab. what is the function to do that?

I mean, i current have a ofFile and a path. i dont match with the function to Open a ofFile in a xcode file (externally of the app)

I would like to help, but this question is unclear.

usually the .txt files or whatever is into your app /data folder is not included into the project structure to look into.
you can use an external text editor to look into.

What i need is to execute a external file using openframeworks. Lets say i have a button, and when i click it a .txt file (already create and in a folder) is execute (lets say in xCode, or in other programe)
I`ve been investigated ofSystem, but no result yets.
anybody?

do you mean to trig to open the file.txt in an external editor (that will open the file)?

you can try to build a system command like in the example:

openFrameworks\examples\input_output\systemSpeakExample\src

// create the command
string cmd = "say " + words[step] + " ";
// print command and execute it
cout << cmd << endl;
ofSystem(cmd.c_str());

But I don’t know where to look at possible commands.

I never tryed it, but I have seen an addon that seems to can do that:

openFile(string path) Opens a file with the default application

ofSystem("open get_started.c -a XCode") works on my OSX.
It will open as an Xcode window, not a tab in your project.
(Have tried it with Terminal, not ofSystem)
