I'm maintainer for a project for the RaspberryPi, a GUI for OMXPlayer called
TBOPlayer. This GUI was originally made for Python 2, but with Python 2
deprecation, I decided to convert it to Python 3. After (supposedly) converting
all of it I had a surprise to see that the events that worked in the original
code with Python 2 didn't work anymore in Python 3 with errors like
File "/home/henio/Projetos/tboplayer/lib/tboplayer.py", line 1566, in
select_track
sel = event.widget.curselection()
AttributeError: 'tuple' object has no attribute 'widget'
And upon investigation, I noticed all the widget events (originally of type
tkinter.Event) were now of type Tuple. WTF. Ok, I tried to circumvent this by
using the tuple "attributes", like, in the event
(('17685', '1', '??', '??', '??', '256', '59467466', '??', '212', '11',
'??', '0', '??', '??', '.!listbox', '5', '1030', '344', '??'),)
I can access the x position of the cursor in relation to the widget by doing:
event[0][8]
Which I did. However, I obviously cannot use any of the Event methods, and this
way I cannot get the current selection from a Listbox, for example, and trying
to gives me the exact error mentioned above. This renders TBOPlayer useless as
the user cannot even select a track for playing.
And unfortunately, I was unable to reproduce this issue with a minimum code, so
I have no idea what's going on.
This issue comment describes how to reproduce the bug inside of TBOPlyaer:
