MATLAB: How to close the GUI from a message box callback

boxcloseguiMATLABmessage

I would like to be able to use a message box callback to close my GUI.

You can create the msgbox and pass the handle of the figure into the callback of the DeleteFcn in the following manner:

h=msgbox('Goodbye')
set(h,'deleteFcn',{'test', gcf})

The callback of the DeleteFcn can be defined to be:

function  test(src, eventdata, k)
close(k); % Close the figure
close(gcbf); % close the message box

MATLAB: Can’t I continue the simulation using ‘PauseFcn’ callback

Since MATLAB Release 2016a, it is not possible the continue a simulation using 'PauseFcn' callback anymore.

We disallowed calling "set_param(gcs,'SimulationCommand','continue')" from the 'PauseFcn' callback, as this is the kind of thing that can easily end up in an infinite recursion if not done properly.

There is currently no workaround to achieve the old behavior; so the best way to move things forward would be to look into other alternate workflows that would be more robust to achieve what you really need.

For example, if you perform co-simulation, an S-Function could do something similar to what the 'PauseFcn' callback is doing. You would not need to pause, the S-Function would call the external environment, wait for it to do its thing and when it is done, it would keep moving forward. That would be a lot more robust and would probably be faster too.

If it is absolutely necessary to retain this workflow, please consider the following workaround in the "PauseFcn" callback:

xx = timer('ExecutionMode','singleShot','StartDelay',0.1,'TimerFcn','set_param(bdroot, ''SimulationCommand'', ''continue'')');
start(xx)

In summary, one creates a timer object and attaches the "continue" function, and then start the timer which will then continue the simulation after the "PauseFcn" callback is exited.

MATLAB: How to trigger the callback function in the listbox component when I trigger the callback function in the edit box

You can call the callback function of the listbox as a normal function.

Please see the attached file 'demoCallback.m' and 'demoCallback.fig' for an example.

1. The app has an edit box and a list box.

2. The list box has a callback function which has:

> disp('This is the listbox callback function')

3. The edit box has a callback function which has:

> disp('This is the edit callback function')
> listbox1_Callback(hObject, eventdata, handles)

4. Trigger the callback function under the list box in the app prints:

> This is the listbox callback function

in the MATLAB Command Window

5. Trigger the callback function under the edit box in the app prints:

> This is the edit callback function
> This is the listbox callback function

in the MATLAB Command Window
