How to add data to an edit field component when a button a pressed in matlab app design

Ok so, is it possible to add some value to an edit field component when a button is pressed in the MATLAB app? So for example, say you have some buttons 'H', 'E', 'L' and 'O', and an edit text field, when you press a button, the corresponding text is output on the edit field and concatenated to the right of the previous input, so, if you press 'H', 'E', 'L', 'L', 'O' the edit field reads 'Hello'?
I have tried this so far in the callback event as the button in pressed:
set(app.EditField, 'String', [get(app.EditField, 'String'), 'H']);
Likewise for the other buttons, but MATLAB fails to run this line.
Any help would be much appreciated. Thanks so much!

It is possible, but your code will have to do the concatenation. The default behavior is for the new value to replace the current value.

Edit fields do not have a string property.
This can be done more succinctly using the functional form rather than set/get.
app.EditField.Value = app.EditField.Value + "H";
By the way, this code goes in the callback for the "H" button, not the editfield.
