Carol Willing  added the comment:

Hi @terry.reedy,

I'm triaging open "turtle" issues. What do you think would be a reasonable next 
step for this issue? Perhaps: a contributor runs the demo and reports back here 
with the current behavior experienced.

[issue14117] Turtledemo: exception and minor glitches.

[Chris Abiad]

Chris Abiad added the comment:

Running through each of the demos, it seems as though only 'penrose' and 'tree' 
have console/shell output.

'penrose' output is a list of information about the current rendering and has a 
format like:
Calculation:0.0009 s
Drawing:   0.0074 s
Together:  0.0083 s
5 kites and 0 darts = 5 pieces.
(... This repeats with updated information for each rendering ...)

I believe that there's too much output right now to include this in the demo 
window's message button area. It might be interesting to show most or all of 
this information with a turtle.write() in the graphical area, but I think that 
the better option is just to remove (or at least comment out) the timing 
information entirely and show only the '5 kites and 0 darts = 5 pieces' portion 
in the message button area.

I could submit a patch for either 'penrose' option if there's interest.

The 'tree' prints a count of the number of turtles created at the end of the 
run. Console output looks like:
1024

I think this is not very useful, except perhaps when debugging the demo. I've 
attached a patch which removes this output.

[Terry J. Reedy]

Terry J. Reedy added the comment:

#22053 added main(), eliminated 'while RUN', and fixed this a 3.x debug 
shutdown message.

The main remaining problem I am aware of now is that some demos 'print' 
messages to the console (or shell), which would be a problem if there were not 
one (as with pythonw).  Except for one demo, the messages would fit on the demo 
window message button. A possible fix would be to call demo.main with the 
button, so mainloop demos could write back to it.
(Normal demo returns are put there now.)

Terry J. Reedy added the comment:

21884 removed or moved global system-changing or gui calls to main. Wrapping 
two_canvases code (except for window preserving mainloop) to a new main fixed 
its problems.

Should remove reload from main driver, and test.

Terry J. Reedy added the comment:

#21823 fixed the Terminator issue 3 days ago.

#21597 is about making the text pane resizable.
The doc strings for peace, planet_and_moon, and tree need a bit of re-wrapping. 
The paint instruction is wrong. I am working on these now.

Use mouse/keys or Stop is a generic prompts for all 'special' demos that 
continue after xyz.main returns. keys is never right for the current set of 
demos.

The text for two_canvases does not load. I think this can be fixed.

[issue14117] Turtledemo: exception and minor glitches.

[Terry J. Reedy]

New submission from Terry J. Reedy tjre...@udel.edu:

Win7, 3.2.2, python -m turtledemo in Command Prompt Window

After running clock example, hitting Stop results in following:
Clock face, including hands, is erased. Day and date are left (intentional?), 
and the following appears back in command prompt window.

Exception in Tkinter callback
Traceback (most recent call last):
  File C:\Programs\Python32\lib\tkinter\__init__.py, line 1399, in __call__
return self.func(*args)
  File C:\Programs\Python32\lib\tkinter\__init__.py, line 487, in callit

  File C:\Programs\Python32\lib\turtledemo\clock.py, line 116, in tick

  File C:\Programs\Python32\lib\turtle.py, line 1936, in setheading

  File C:\Programs\Python32\lib\turtle.py, line 2646, in _update_data
self.screen._incrementudc()
  File C:\Programs\Python32\lib\turtle.py, line 1285, in _incrementudc
raise Terminator
turtle.Terminator

Demo continues to run.

Paint: Left clicking mouse moves dot without painting. Right clicking changes 
mode so left clicking draws line. It also causes some filling of enclosed 
regions. This double action is slightly obscure. The prompt on the bottom of 
the screen says Use mouse/keys or Stop As near as I can tell, keys are 
inactive. So prompt could delete '/keys'.

Module doc strings that explain each demo should be wrapped so that they appear 
in the code window without scrolling. Or the left window could be wider, 
especially if the user widens the window. 800x600 screens are pretty rare these 
days. 

'Wikipedia' is a poor name for something just because it happened to be there. 
'Rosette', for instance, would be better.
