Hello !
I have already created a button that allow user to browse a file and a TextArea that display the File Path.
function Browse(app, event)
[FileName,FilePath ]= uigetfile();
ExPath = fullfile(FilePath, FileName);
app.FileTextArea.Value = ExPath;
end
And now i would like to create another button that launch a matlab script (function) with the file in parameter I don't know how to do that, first time i use app designer.
Thanks for helping !
Edit : i tried this :
function Launch(app, event)
Path = string(app.FileTextArea.Value);
testLectureXML(Path);
end
testLectureXML is my matlab script.
But it returned me :
Undefined function 'Launch' for input arguments of type 'Apptest'.

hi!
I am having the same problem but the solution you have posted somehow doesnt work for me.
In my app designer there's no "edittext" but rather an "edit field (text)" and "editfield (nummeric)" and if I execute this code:
function RunButtonPushed(app, event)
file = app.Editfield.Value;
scriptName(file);
end
and i get this error: Attempt to execute SCRIPT Test_Zeilentausch_qualitaet as a function: [path]
But I can't write "app.editfield.string" it doesnt exist.
Do you have any solution on this? and do you know if the values appear in the workspace once I run the script?

- Open your project in app designer : https://www.mathworks.com/help/matlab/ref/appdesigner.html
- Add the button: https://www.mathworks.com/help/matlab/creating_guis/choose-components-for-your-app-designer-app.html
- Add a ButtonPushedFcn callback function to the button: https://www.mathworks.com/help/matlab/creating_guis/write-callbacks-for-gui-in-app-designer.html and https://www.mathworks.com/help/matlab/ref/matlab.ui.control.button-properties.html#d117e1549488
- From within the callback function, use the "app." structure to find the handle to your GUI object that contains the file path string. Then access the string property.
- Now you can call your external function with the file path input.

You could do either (or both). If your .m function is designed to be called by additional callers other than your app, it would be smart to do that in your external file.
Doing it in your app checks the validity before sending the variable. It's more of a conceptual question. I'd do it in the external file.
