Opening a GUI from another GUI with a delay in App Designer

I have to open a second GUI2 from a main GUI1. I would like to open the GUI2 with a delay. I used the timer in this way: t = timer('TimerFcn', @(~,~) uiwait(app2.UIFigure), 'StartDelay', 5); start(t); and pause(5) but the second GUI is open immediatley. The istruction to open the GUI2 is uiwait(app2.UIFigure). In documentation about uiwait(app2.UIFigure) I have seen that I can use uiwait(app2.UIFigure, timeout) but also this method is not working.

I have to open the GUI2 in a loop. This is the code

for i=1:30

% do something

uiwait(app2.UIFigure)

% do something

I used also this:

time_await = 5; % Time await in seconds

t0 = tic;

% Start timer

while toc(t0) < time_await

drawnow;

end

No solution is working and I don't know how to open the second GUI with a delaly

I suspect the new GUI is opened because Matlab is unable to store the anonymous function without creating that new GUI.

What you can do is write a wrapper function that opens the second GUI. That way you can use the timer to run that function with a delay and all should be well.

Hi Tania,

As per my understanding, you would like to open a second GUI2 from main GUI1, with some x seconds delay.

You can use pause() function to delay the execution of the code. Here is an example code for opening a second GUI2 from GUI1 after a delay of 5 seconds:

% Button pushed function: Callback in which you want to open second GUI
function buttonPushed(app, event)
    % Introduce a delay of 5 seconds
    pause(5);
    
    % Create an instance of the second GUI
    secondGUI = GUI2;
    
    % Show the second GUI
    secondGUI.UIFigure.Visible = 'on';
end

Please note that you can customize the above code to meet your specific requirements.
