Creating Dynamic Vector in Matlab GUI

I have an image upload box in my Matlab GUI. In this GUI, I would like to create a vector that adds the actual file name of each of these images that I have uploaded. For example: If I upload 5 images I want a vector with 5 file-name listed. I need to track what files names have been called in the past for other parts of my code. I have tried using a counter loop type operation with no success. Any suggestions are much appreciated!

Hi!

Use a cell array for your file names (strings). Each time you upload a new image you add one cell to the array. After that store the array with "guidata", so that you can get it back every time a new image is uploaded.

can you explain how to initialize the cell array on order to save the first file name inputted?

Hi!

The GUI has an opening function that is executed before the GUI is shown. I place my initial values there:

handles.FileNames = {};

% Update handles structure
guidata(hObject, handles);

Afterwards in the upload callback function you can add the file name like

handles.FileNames = [handles.FileNames; CurrentName];

Don't forget to store "handles" at the end of the callback function!
