[Tkinter-discuss] clipboard and bytes

[Vasilis Vlachoudis]

I did something else.
I've used the binascii.b2a_hex() and a2b_hex() functions
to convert the bytes() to a hex string and the reverse (double in size, and
a useless UTF-8 conversion, encode/decode) 
This way it works but not a clean approach,
since I am copying in the clipboard binary data in a form of ascii.

Is there a way to create a new mime format and advertise
the format somehow in the clipboard?

Many thanks!

I works within the same process.
When I try to launch it twice, so I can have clipboard exchange between different processes

I get the following exception:
Traceback (most recent call last):
  File "/usr/lib/python3.6/tkinter/__init__.py", line 1702, in __call__
    return self.func(*args)
  File "foo.py", line 41, in paste
    res = root.tk.call(clip)
_tkinter.TclError: invalid command name "139879786444744cp"


I saw in the documentation that by default it uses the UTF8STRING as type
I've tried to force it to type="STRING" but with no success

Or maybe this slightly modified example comes closer to what you are
looking for:

from tkinter import *

root = Tk()

def copy(string):
    def cp():
        return string
    copyfunc = (root.register(cp))
    return(copyfunc)

root.clipboard_clear()
root.clipboard_append(copy(b'foobar'), type='foo')

def paste(ev):
    clip = root.clipboard_get(type='foo')
    res = root.tk.call(clip)
    print('->', res, type(res))

root.bind('<F1>', paste)
root.mainloop()



Regards

Michael
