- Create the button in your GUI (drag and drop the button onto the designer workspace)
- Right click the button, hover over 'callbacks', select 'AddButtonPushedFcn callback'.
- From the code view that will open after adding the callback function, use matlab's uigetfile function.
Creating a file upload option/button in App designer

Hi all
I am currently using MATLAB App designer to create a waveform generator user interface, and the idea is apart from some standard fucntion been selected and hence generated, i.e. sine/cosine, the interface should also allow user to upload their interested signals such as modulated signal. Therefore I would like to create such a function using App desinger so that when the user click on the button, a file viewing window could pop up for file uploading.
Would someone could give me some hints how I am able to achieve this? Many thanks.
Kind regards,
Chen

No, you could change the file extension '*.mat' to specify the type of file you'd like to open or any other type of filter. It's quite flexible.

How can I make it so that when I try to open a file with another extension, it shows an error box and if it is the correct one, it shows a correct text box?
