Callback functions don't have outputs, at least not how they are called by the usual workflow of a UI in MATLAB.
I'd probably write a function that your pushbutton callbacks can use to set the status message appropriately, something like:
function setStatusMessage(f, newmessage)
f.statusWindow.String = newmessage;
end
where statusWindow is the component in the figure that contains the status message.
That's also pretty self-documenting.
function gridSmoothedData_Callback(...)
% Do some processing on the data
setStatusMessage(f, "Processed");
% Maybe call the next step in the process
updateSmoothedDataVisualization(...);
end
Without even seeing what the function accepts can you tell the purpose of this callback, what the state of the process is when this function finishes, and what the next step is?
