On 64bit Python, lParam[0] and lParam[1] returning large values

[simon2x]

I have been experimenting with this code. The shortcut key never works because the key_code, scan_code (lParam[0] and lParam[1] respectively) returns large values, therefore not in the keycode list.

For example, if I change the loop to just print the event

for h in self.handlers:
    #h(event)
    print(event)

It will return large values.

KeyEvents(event_type='key down', key_code=373662154874, scan_code=953132227430973456, alt_pressed=False, time=223783752) KeyEvents(event_type='key up', key_code=373662154874, scan_code=953132227430973584, alt_pressed=False, time=223783752)

Out of curiosity, are you using a standard US keyboard? Other keyboards may have very different scan codes (I think).

[simon2x]

I'm using a UK keyboard. The same code works (i.e. detects the correct scan code) with python 2.7.

I have the same problem with python 2.7 x64, but it works with 2.7 x86. So I think this is the problem with x64.

[ethanhs]

Can @swprojects can you tell me the version of Python 3 you tested this on? Also, what bitness of 2.7 you tested?

EDIT: Furthermore, I can not reproduce this on Python 3.5 x86, so I am going to hazard a guess that @bearqq is correct that this is a bitness difference. I will wait for the word on bitness. I am not sure why the scancode would report differently on x64, but I will investigate this.

[simon2x]

ah yes. I am using it on python 2.7 x86 and python 3.5 x64

[ethanhs]

Okay, I will try to figure out why these values are so different. Hopefully, there is just an offset, but I might need to do some thinking on this.

[ethanhs]

So, I am really not sure why, but each time you press the key, the scan code increases. I am getting similar behavior, but I'll look at the keycode and see if I can (should) use that instead.

Looks like the key codes are consistent. For 0.8 I will re-write to use keycodes instead of scancodes.

[simon2x]

I have recorded most, but not all of the keycodes ( because of lack of buttons on my keyboard ). Hopefully, the values of keycodes are consistent with yours.

Any values I haven't tested are commented out in the dictionary.

Thanks @swprojects those do seem to correspond with the key codes I am getting. I was about to generate that list this morning, but you saved me the work :) I will try to fill in the gaps later.

[panofish]

I am also using 64 bit Python 2.7 and I am getting this error when testing with demo program and pressing a key.

...line 46, in print_event scancode=int(str(e)[(start+10):end])

ValueError: invalid literal for int() with base 10: '101567335076200448L'

[ethanhs]

@swprojects I'm afraid I don't really have time to work this out at the moment. There is the beginnings of a fix in the dev branch, and if you wish to fix this for x64 and contribute back it would be appreciated, otherwise, it may be a while.

[panofish]

OK thanks ... your original sharing was much appreciated. I will patiently check back once in while.

Thanks.

@ethanhs thanks very much for this, looks much cleaner. I will try to help with the x64 fix

@panofish and a fix for the GUI mainloop (if possible)

I have forked this project, which I will try to dedicate some time to work on dev

This is fixed in c070a01a7f7ea5daba4826a914fbee7bcb7aabff and above (currently in the dev branch). Please uninstall previous versions before installing again with pip or setup.py.
