MATLAB: How to close UIAlert in AppDesigner by command

appdesignerMATLABuialert

I want to show some prompt message before dealing with a large data, after that I want to close it automatically without user's click action.

How to do that?

Thanks!

You can use message box tool in the base code itself

h = msgbox('Please Wait ...you are dealing with large data', 'Processing');
onCleanup(@()delete(h));

Under the condition when you are dealing with large data add this code

The onCleanup command here deletes the message box.

This seemed to work for me

h=msgbox('Click OK');
close(h);

You can put the close() in a timer callback if you want to close it after a certain time. But check that h exists (see the FAQ for methods). http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

MATLAB: How to close an uialert programmatically

The uialert window cannot be programmatically closed, at least not in r2020a. You can, however, make the uialert non-modal which will allow you to interact with the base figure (app) while the uialert still exists.

uialert(uifig, 'message', 'title', 'Modal', false)

Alternatively, you could use a msgbox which outputs a handle that you can use to delete at any time but this will not be automatically centered on the app like the uialert panel does.
