How to 'Quit' an app (default Processing window)

[vsquared]

Currently the only method to quit an app on a Mac is to use the close window button at the top left corner of the window. Normally there would be a cmd-Q menu item under the app menu on the menubar. There is a default menubar item called 'Python' but there are no menu items below it where the 'Quit' menu item would normally go. In addition, I usually put a 'Quit' button on the main window canvas. If I use a custom button and call exit() when pressed (which works in Processing), it gives the following error:

org.jpype.PyExceptionProxy
	at org.jpype.JPypeContext.createException(Unknown Source)
	at org.jpype.proxy.JPypeProxy.hostInvoke(Native Method)
	at org.jpype.proxy.JPypeProxy.invoke(Unknown Source)
	at jdk.proxy2/jdk.proxy2.$Proxy6.run_method(Unknown Source)

	at processing.awt.PSurfaceAWT$9.callDraw(PSurfaceAWT.java:1386)
	at processing.core.PSurfaceNone$AnimationThread.run(PSurfaceNone.java:356)

Process ended with exit code 0.

If I use a JButton with a handler, there is a similar more lengthy error. Is there a better way of doing this or should I call a different method? The menubar is shown below. If I could programmatically add a 'Quit' menu item to the menubar that would also be nice if we have access to it.

Can you try exit_sketch()?

https://py5coding.org/reference/sketch_exit_sketch.html

If your button called that method it might do what you need it to do.

py5 has no exit() method because it would conflict with the Python builtin function. Instead it is renamed to exit_sketch().

I just checked our Tips for Processing Java Users page and it does not mention the exit/exit_sketch rename. I'll open an issue so I remember to add that later.

exit_sketch() works without error when used with a custom button in default window. Thanks for that and also the helpful links.

Great, glad we could help!

Just a note to register that the Tips page has been updated to include exit_sketch(), yay!
