To enable users to select a specific folder for saving notes from a text area in MATLAB App Designer, the “uigetdir” function can be utilized. This function prompts the user to choose a directory from their desired file storage location. For detailed information, refer to the following official documentation:
The existing implementation can be enhanced by replacing it with the following code:
% Get the value entered in textArea
value = app.TextArea_.Value;
% Prompt the user to select a folder
folder = uigetdir(pwd, 'Select Folder to Save Notes');
if folder == 0
disp('User canceled folder selection.');
return;
end
% Full path to the new file
fileName = ‘DataReport.txt’;
fullFileName = fullfile(folder, fileName);
% Save the text to the file
writecell(value, fullFileName, 'QuoteStrings', false);
This approach ensures that the user is prompted to select a folder before proceeding. Upon successful selection, a new file named “DataReport.txt” is created in the chosen directory, and the contents of the text area are written to it.
