Hi, when I ssh to a server then I want to try to run the script that include a text editor I get that error.
it's my script:

from TermTk import TTkUiLoader, TTk, TTkWindow
class MyTextEditor(TTkWindow):

    def __init__(self, root):
        self.root = root

        ## UI ##

It works correctly on the local machine

It happens for all text or line editors if I try to select something in the text input field or text edit. it crashed. How can I disable copy-paste and prevent this exception?

Also, it happened for ttkDesigner if I tried to run it from ssh but it's unimportant. how can I disable copy-paste for line editing or text editing?

Also, printing text on output after quitting ttk will help me. I want to show text to the user that the user should copy and it runs over ssh

yes
I noticed itwhen I tried it over ssh
I need to handle that exception
you can try to export X

ssh -X <HOST>

In my quick test it seems to works
I am sure putty has a similar option that can be enabled but I don't know if it is properly handled in Windows

Also, printing text on output after quitting ttk will help me. I want to show text to the user that the user should copy and it runs over ssh

This could be achieved with a print after the main loop:
But there is an issue I have to investigate that sometimes the terminal is not clear when exiting so any printout will get corrupted #236

from TermTk import TTk, TTkWindow, TTkButton

root = TTk()

TTkButton(parent=root, pos=(0,0), size=(40,5), text="Quit", border=True).clicked.connect(root.quit)

win = TTkWindow(parent=root, pos=(0,5), size=(30,10))
win.closed.connect(root.quit)

root.mainloop()

print("Test\nTest\nTest\nTest\nTest\n")
