I'm developping some tests with the matlab.uitest framework. Everything is fine until my app generates an uialert, which is expected behavior.

The problem is, once uialert pop-up is there, I can't do any more gesture (choose, press, drag...). If I unlock the app and close the uialert manually (with matlab.uitest.unlock(fig)), then everything is fine again.

So, do you know any way 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.

hi

use this code instead:

d=uiprogressdlg(app.UIFigure,'Message',message,'Title',title,...
    'Icon','error','Cancelable','on','Indeterminate','on');
for i=5:-1:1
    d.Message=[num2str(i) ' seconds to close ' ];
    pause(1)
end
close(d)
