display a tic toc timer in a gui window
in [Matlab]

From: David on 6 Aug 2010 09:57 Hi! I am new to programming and I have a question. I have a GUI window that I created without using GUIDE. There is a start Timer push button and an edit window next to it. When the Start Timer button is pressed it starts a timer using tic. I want the running elapsed time to be shown in the edit window, like a timer on a watch. I can not seem to get this to work, any suggestions? Additionally is there a way to stop the tic timer from running in the background? Thank you, Nicole

Eg. if you want it to update every 1 second: %%% toc_it = @set(handles.editbox,'String',toc); t = timer('TimerFcn',toc_it, 'Period', 1.0); tic start(t); %%%

I had a tic timer running in the background and when i added that code it updated the Edit window every time I pressed the start timer button. When I restarted Matlab and did not have a timer running already I received an error message saying that I must run tic first.

I had a tic timer running in the background and when i added that code it updated the Edit window every time I pressed the start timer button. When I restarted Matlab and did not have a timer running already I received an error message saying that I must run tic first. To elaborate: Since you want it to continuously update: T = timer('TimerFcn',myfun,'Period', 1,'ExecutionMode','FixedRate'); set the execution mode to fixedrate also in my function above, you'll most likely need this: toc_it = @(obj,evnt)set(handles.editbox,'String',toc); Good Luck
