Error when I try to update an edit text field in a GUI
2 views (last 30 days)
I want to change the default value of an edit text field in a GUI, but when I try to update the field from the code, I get an error.
set(handles.month,'String','Does this work?');
gives me the error "Dot indexing is not supported for variables of this type."
It seems that Matlab is objecting to handles.month, but I'm not sure why. handles is passed in to the function where I am calling set() from, so it shouldn't be an issue of inability to access the variable handles. And month is the correct name of the field I'm trying to update.
I don't think my syntax is wrong, based on examples such as https://www.mathworks.com/matlabcentral/answers/18341-display-a-value-in-edit-text-in-gui
Nor does it work to try
month = handles.month
set(month,'String','Does this work?');
which gives me the same error about dot indexing.
