I understand you want to show the default value in the start by pressing enter. The issue is that text fields only have 2 call back options, and both only work if value is changed. There is a possible work around. You can add a keyboard event listener to the UIFigure of the app to react to pressing enter. However this will only work if your top edit text is not in focus, so press enter before clicking on the top text, or take the top text out of focus by clicking anywhere else on the app. The code for the keyboard callback is below
function UIFigureKeyPress(app, event)
key = event.Key;
if key == "return"
% Retrive data
name = app.Input.Value;
% Clear it
app.Input.Value = '';
% Log it
app.Output.Value = name;
end
end
