It seems like you are trying to structure your MATLAB GUI code by separating the callbacks into different files.
The error encountered is because the “remoteURL” variable is not defined in the scope of the “callbackRemoteURL” function. To fix this, you should pass the “remoteURL” object to the callback function as an argument.
Here is one of the ways in which you can organize your code:
Main file (main.m): It will contain the GUI setup. It will also initialize the callback functions and assign them to appropriate UI components.
% Setup GUI
slicingObjects = uifigure;
% ... (rest of your setup code)
% Set up callbacks
callbacks = GUIcallbacks;
% Set the callback functions
remoteText.ValueChangedFcn = {@callbacks.remoteText, slicingObjects};
remoteURL.ValueChangedFcn = {@callbacks.remoteURL, slicingObjects};
Callbacks file: It contains all callback functions.
% GUIcallbacks
function callbacks = GUIcallbacks
callbacks = struct(...
'remoteText', @callbackRemoteText, ...
'remoteURL', @callbackRemoteURL ...
);
end
Individual callback files:
% callbackRemoteURL.m
function callbackRemoteURL(hObject, event, slicingObjects)
% hObject refers to the UI component that triggered the callback
% slicingObjects is the main figure which you passed as an argument
remoteURL = hObject.Value;
End
% callbackRemoteText.m
function callbackRemoteText(hObject, event, slicingObjects)
% CODE HERE
End
Make sure that each callback function file is in the same directory as the “main.m” file or in MATLAB's path, so they can be accessed when running the “main.m” file. Also, ensure that the arguments passed to the callback functions match the signature of the function definitions.
