Does the base Matlab have something similar to Java's command 'setDefaul​tCloseOper​ation'?

1 view (last 30 days)
So for context, I have created a plot that simulates objects moving within a 2D plot with a bunch of other mechanics and whatnot, but I was specifically wondering if there was a way to stop the program, or for the program to be able to detect when the created plot window has been closed by the user? I have looked into the
status = close('all','hidden')
command from, but I don't entirely know the syntax of the command to get the result I'm looking for.
Thanks in advance. :)

No you set the callback 'DeleteFcn' of the speific figure where you want to detect the event when user close it.

If you want to detect if a handle is a valid Handle Graphics object, use ishghandle.
f = figure;
f2 = figure;
x = 42;
close(f)
ishghandle([f, f2])
ans = 1×2 logical array
0 1
ishghandle(x)
ans = logical
0
f is not a valid handle because the figure has been deleted.
disp(f)
handle to deleted Figure
If you want to intercept the figure window closing (to avoid closing or to do something before closing the window) consider defining a CloseRequestFcn for your figure instead of a DeleteFcn. See the entry for this property in the Window Callback sections of the Figure properties or UI Figure properties documentation pages for more information.
