Rename file using multiple drop downs (app designer)

2 次查看(过去 30 天)
I have .m code that executes an app made in App Designer. A button in the app saves a file as "TestData.csv" in a specified folder. I would like to add multiple dropdowns to the GUI with descriptions, and then a rename button that renames the file according to the selections in the drop down. The addition to the GUI would look something like this:
The goal is to have matlab locate the file named "TestData.csv" and rename it to "Description1_Description2_Description3_Description4.csv". Is this possible? Here's what I have so far. What I cant figure out is how to string together the event.Values and rename the file with the selected drop downs. Not sure if movefile is the correct command here.
function Rename_Data_Callback(app, event)
app.Description1.Value = event.Value;
app.Description2.Value = event.Value;
app.Description3.Value = event.Value;
app.Description4.Value = event.Value;
%some sort of code that creates the new name with '_' between each value
movefile C:\Users\Desktop\TestData.csv C:\Users\Desktop\NewName.csv
end

function Rename_Data_Callback(app, event) %callback for button press
app.Description1DropDown.Value;
app.Description2DropDown.Value;
app.Description3DropDown.Value;
app.Description4DropDown.Value;
TestData='C:\Users\Desktop\TestData.csv'; %location of file to be renamed
rename=strcat("C:\Users\Desktop\",app.Description1DropDown.Value,'_',app.Description2DropDown.Value,'_',app.Description3DropDown.Value,'_',app.Description4DropDown.Value,'.csv');
movefile(TestData, rename);
