How to modify the text visibility in a Gui that created using App Designer

Dear Coder,

I have develop a gui using AppDeveloper.

In a separate main.m file, I would like to display the GUI and change the visibility of a Label. Say the component having name of app.Label.

If using GUIDE, I know the command to achieve this will be

set(handles.LabelTag,'Visible','off'); 

But having migrated to App Developer, the command is not working.

Some method in the net show that the code should be something like below, however, its is not working for my case.

app.Label.Visible = 'off'

Appreciate if someone can show which part i do wrong

What is the exact name of the component? I would suggest you to rename it if its only Label.

For example, if you rename it to Component1EditField, then to change the visibility, you can use:

app.Component1EditFieldLabel.Visible = 'off';

Thanks for the quick reply.

However, the propsed line does not work as intended.

FYI, Im having two files. 1) GuiApp.mlapp and 2) GuiApp.m.

Then, in the GuiApp.m, I would like to display the figure and change the visibility of the component, This is achieve as follow

GuiApp ()  % To execute and display the figure
app.Component1EditFieldLabel.Visible = 'off';  % To make the component invisible

However, Im not able to make the component invisible using the line suggested above.

Do you know where I do wrong?

Thanks

"Then, in the GuiApp.m, I would like to display the figure and change the visibility of the component"

Are you returning app from GuiApp.m and passing app as attributes to the same? i.e.

Is your first line of GuiApp.m is:

function [app] = GuiApp(app)

?

If not Please make it this way.

This makes sure that you have access to the app components from the .m file as well.

Also, in the code you have written above, make a small change.

GuiApp(app);  % To execute and display the figure % add app in brackets
app.Component1EditFieldLabel.Visible = 'off';  % To make the component invisible

Hi Ajay, appreciate for the helps. But, I still not able to make thing work though amend the code according to your suggestion.

Can you have a look at the code accessvle from this link, whether it is correct or not. FYI, Im using MATLAB R2019b.

Thanks once again for your time entertaining this request

Ok, this is a different context now.

Replace the whole main.m file with

x = GuiApp;
x.Component1EditFieldLabel.Visible = 'off';
