Hello!
I’m a college student who wants to be a Python engineer, attending a Korean university.
Working on the project, and I came here because there was a problem with themed tkinter.
There is a problem with the Korean IME in the ttk.Entry object.
Hangul(Korean) creates words from a combination of letters(initial, medial, finale).
I’d like to dynamically print those letters with get() method whenever I type that letters into ttk.Entry
But only when ttk.Entry enters one completed letter, the letter is printed.
Desired example)
input ㅎ >>> print console: ㅎ
input ㅏ >>> print console: 하
input ㄴ >>> print console: 한
Actual action)
input ㅎ >>> print console:
input ㅏ >>> print console:
input ㄴ >>> print console:
input whitespce >>> print console: 한
To look up that using event(type: QInputMethodEvent) in the QLineEdit of PyQt5 with event.preeditString(), the action I want will be implemented!
However, I understand that tkinter and PyQt5 are difficult to mix using, because of different event loops.
I’m already been working on the project quite a bit, so hard to change the entire code to PyQt5.
I would like to implement such as preeditString() only in certain parts…
What are the options? Only way to change all code…?
