Display real time clock in GUI

Hi all guy.

I displayed it in GUIDE matlab. it work good. However, it don't run when i callback function

other

Timer(handles);%call timer
function Timer(handles)
while find(get(0,'children')==handles.figure1)
    nows = fix(clock);
    timerStr = [num2str(nows(4)),':', num2str(nows(5)),':', num2str(nows(6))];
    set(handles.time,'String',timerStr);
    pause(1);     
end

You have an infinite loop. The pause() call permits the infinite loop to be interrupted by a GUI callback, but the code in the infinite loop will not continue running until the callback returns. Using pause(1) does not mean that 1 second later, no matter what MATLAB is doing, that control should be given back to your infinite loop.

What you should do is create a timer object that should run evern 1 second. The code for that timer object should update the GUI clock, and then should return.

I think you will find code for a clock in the File Exchange.

Do you can fix it ?. It worked until i press callback other function .

And it run when i exit function. I think i put wrong position in GUI.

Thank you.

He already suggested the solution: use a timer object.
