[issue31496] IDLE: test_configdialog failed

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Updated patch for issue31500 fixes this issue. I guess the problem was with 
using fixed size for the dialog widget. It was too small and the part of the 
example was not visible.

Terry J. Reedy added the comment:

If the test only fails with a HiDPI screen, then it must somehow be related.  
But if the highlight sample is normal size, like the font sample in
https://bugs.python.org/file47141/Screenshot_20170917_213616.png
then the relationship must not be as simple as I was thinking.

No, the fix for issue31500 doesn't affect this issue.

Terry J. Reedy added the comment:

On windows, hs.see(start), followed or not by update_idletasks(), has no effect.

Does the fix for #31500 fix this also?

About the 'invalid command name' message: PR 3622 was not yet merged on your 
machine.

Inserting hs.see(start) just before hs.bbox(start) fixes the issue.

I have added some debug prints. Here are outputs, with and without a fix.

Are you running on Linux or Mac?  What tk version?

About the 'invalid command name' message: PR3622, patching idlelib.codecontext, 
merged to master 13 hours ago, fixed this for me on Windows.  (It added 
CodeContext.__del__.)  Did it fail on your machine or was it not yet merged on 
your machine?

About the test failure.  Hs is a Text with about 14 lines.  The test initially 
executes
hs.see(1.0)
hs.update_idletasks()
hs.bbox(start) means that the tag start is not visible,  which should 
realistically not be possible.  But a quick web search suggests there have been 
problems with HiDPI and tk, and hence tkinter.

I am curious what value of start fails.  Could you run once with 'print(start)' 
added above bbox(start)?

Does inserting the following just before hs.bbox(start) fix the issue?
hs.see(start)
hs.update_idletasks()
If not, we can skip.  Does the following print one or multiple skip messages?
try:
x, y, dx, dy = hs.bbox(start)
except TypeError:
self.skipTest(f'bbox failure with start {start}')

Maybe this is related to HiDPI display.

On 2.7 the test is passed.
