Have title of plot change IF edit field has text, otherwise default

Plots created in my code default the title of the plots to the folder in which the data comes from. Usually this is what is needed, however if the user wanted to change it they could type into an edit field. How do I make the code check for text to use and if not just keep the default.

I have this but it won't change when I type into the edit field.

% Set title font size
if app.GraphTitleEditField == 0;
    title(app.GraphTitleEditField.Value,'FontSize',32);
else
    title(ParentFolderName,'FontSize',32);
end

You are comparing the edit field object itself to 0, instead of the content of the edit field. Try

if ~isempty(app.GraphTitleEditField.Value)

end

You may need char() if the Value is a string, instead of a char array:

if ~isempty(char(app.GraphTitleEditField.Value))

end

Oh thank you! Still learning some of the little nuances with coding.
