Gustavo - you just about have the correct code. All that is missing is to build the cell array of files names within the for loop, and then set the data of the uitable outside of the loop. Something like
nameDir = uigetdir();
% guard agains the user cancelling the uigetdir dialog
if ischar(nameDir)
listDir = strcat(nameDir, '/*.jpg');
files = dir(listDir);
numFiles = length(files);
% set the size of the cell array
paths = cell(numFiles,1);
% build the cell array of files
for l = 1:numFiles
nameImg = files(l,1).name;
paths{l} = fullfile(nameDir, nameImg);
end
set(handles.uitable1, 'Data', paths);
end
The above is very similar to what you have. The code just guards against the user cancelling the get directory dialog (returns 0 on pressing of the cancel button). It also makes use of fullfile to build the file name from the parts (the folder and file name) - that way, you don't have to be concerned with the forward or backward slash. Once the cell array is built, then the uitable is seer with the path data.
Try the above and see what happens!
