In my gui3 , i want to break loop when i close the gui figure window

I created closeRequestFunc with this code;

function figure1_CloseRequestFcn(hObject,eventdata,handles)
clear playsnd
delete(hObejct);
end

My for loop works. But i want to add if statement to break loop when closing figure window

i tried this but not work.

if (handles.figure1_CloseRequestFcn)
    break;
end

What do you suggest ???

You can write a small function that tests if the object still exists. Unfortunately, exist and isobject don't solve this for you.

if isdeleted(handles.figure1)
    break;
end

function tf=isdeleted(h)
tf=false;
try
    get(h);
catch ME
    if strcmp(ME.identifier,'MATLAB:class:InvalidHandle')
        tf=true;
    end
end
end

isgraphics( handles.figure1 )

should tell you this too?

@Adam, good point, didn't think about that function. You could also move that comment to an answers.

isgraphics( handles.figure1 )

will tell you if the figure is still active or has been deleted.
