I’ve done some quick browsing of the Tk source code and it appears that Tk
assumes that -[NSApplication sharedApplication] returns an instance of a
Tk-specific private subclass of NSApplication and that won’t be true when the
Tk runloop is started before the Cocoa one.
My question: is my analysis correct? And has anyone successfully mixed PyObjC
and Tkinter in this way? I guess this issue could be avoided by initialising Tk
before calling into Cocoa.
I'd say your analysis is more or less correct. The previous maintianer
of Tk/Mac, Daniel Steffen, noted this in a bug report at
https://core.tcl.tk/tk/tktview/3033786fffffffffffff.
I've had success embedding Cocoa widgets from within Tk (Quicklook
views, NSToolbar, etc.) where Tk has no direct knowledge of the Cocoa
bits. But the Tk event loop has to be in charge for this to work because
of Tk's architecture. I don't think that calling Tk from Cocoa is feasible.
