Hello
Thanks for this. Sadly, that flag stays 1 when the [pd] subpatch window
containing my GUI is closed. I must be missing something.
What is the simplest GUI source code I can read, ideally with loads of
comments, to see the best practices? At the moment, when the subpatcher window
is closed its ‘pdtk_canvas' is destroyed ("pd -d 5” helped a lot to understand
the ‘dance’)…
To reiterate:
- glist_isvisible() is 0 when subpatcher is opened
- gobj_shouldvis() is always on, subpatcher opened or not
Thanks all and sorry for the newb questions!
