New to Tkinter. Initially, I had some code that was executing button commands at
creation, rather than waiting for user action. Some research here gave me a
solution, but I am not sure why the extra step is necessary.
This causes the "graph" function to execute when the button is created:
Button(root, text='OK', command=graph(canvas)))
However, this waits until the button is pressed (the desired behavior):
def doit():
graph(canvas)

Okay so I have a whole bunch of begininvokes to update my gui. I enable/disable, change the text, and all that beautiful stuff.
This is, unfortunately, how my code looks right now:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
