在 MATLAB Online 中打开

TYPE1 = {'AUDI','MARIA OWN THIS GREAT CAR'};

selectedCar = handles.popupmenu1.Value;

switch selectedCar

case 2

owners = TYPE1;

end;

-file modify.m-

here i have a pop up and an edit text

How cand I call variable TYPE1 from file display.m, display it on edit text and after that re writing it back to same variable on display.m

Thank you!

@Geoff Hayes those two.m files are script files made by automatically by GUI. I want to call the text generated in an edit text box by a function in a pop-up menu from first file in another edit text box file and modify and save in a first file. I hope I mede my self clear. If not please let me know. Thanks

@Cristian Martin - can you show some of the code or post the two files? I'm just curious as to what data is being written to these files. It may be simpler to just keep the data (that is written to the file) as a variable/property of the handles struct so that you don't have to open the file to read the contents just to write to the edit text control. Unless you are allowing the user to write data to the file via the GUI

When you call an edit text box, the user inputs some text which will then save. If it is a popup window you are using, you should be able to get the outputs from the user. If this is a popup window in the GUI itself, the value you are looking for will look like "handles.popup1.String"
