Close uialert - App designer

In App designer I have a function called

DayButtonPushed(app, event)

With the following code:

aFig = uifigure;             
message = sprintf('March \n\nYear 2022');
uialert(aFig,message,'Info','Icon','info');

When I press the OK it does not close the background window. Therefore, how can I close all upon pressing ok (image attached)?

Why create a uifigure() there? uialert() will create its own uifigure()

This is what I see in the examples at https://www.mathworks.com/help/matlab/ref/uialert.html

Is their another way to solve it?

[Walter Roberson]

Ah, I see.

It is a modal alert, so it will not return until the user has clicked. So after the uialert() call you can destroy the figure.

[Ali razi]

if I add close(aFig); it automaticly close. Any idea how to solve it?

[Walter Roberson]

I see what you mean.

I had a look in the source code, but the graphics works a completely different way for uifigure() and in the time I was willing to spend, I did not find a method.

Add a CloseFcn may be a workaround if you don't want to use the uifigure anymore.

aFig = uifigure;             
message = sprintf('March \n\nYear 2022');
uialert(aFig,message,'Info','Icon','info','CloseFcn',{@closefig,aFig});
function closefig(src,event,aFig)
    delete(aFig)
end

@Simon Chan That's a good idea.
