删除 tkinter 文本默认绑定 [英] Remove tkinter text default binding

问题描述

我正在制作一个简单的 tkinter 文本编辑器，但我希望尽可能删除 文本小部件 的所有默认绑定.

I'm making a simple tkinter Text editor, but i want all default bindings of the Text widget removed if possible.

例如，当我按 Ctrl + i 时，它默认插入一个制表符.我做了一个事件绑定来打印文本框中有多少行，我也将事件绑定设置为 Ctrl + i.

For example when i press Ctrl + i it inserts a Tab character by default. I made an event binding that prints how many lines are in the text box, I set the event binding to Ctrl + i as well.

当我运行它时，它会打印文本框内的行数，但还会插入一个制表符.

When i run it, It prints the number of lines inside the text box, but also inserts a tab character.

我想知道如何覆盖默认绑定，或了解如何删除所有默认绑定.

I want to know how i can Overwrite the default bindings, or learna way how to remove all the default bindings.

顺便说一句，这是我的代码:

Heres my code btw:

from tkinter import *

class comd: # Contains primary commands
    # Capital Rule ----------------------------
    # G = Get | I = Insert | D = Draw | S = Set
    # -----------------------------------------

    def Ggeo(self): # Get Geometry (Get window geometry)
        x = root.winfo_width()
        y = root.winfo_height()
        print("Current Window Geometry")
        print(str(x) + " x " +str(y))

    def Idum(self): # Insters "Dummy Insert"
        import tkinter as tkin
        tbox.insert(INSERT, "Dummy Insert")

    def Ilim(self): # Prints How many lines are in
        info =  int(tbox.index('end-1c').split('.')[0])
        print(info)



root = Tk()
root.geometry("885x600-25-25")

tbox = Text(root, font=("Courier","14","bold"))
tbox.pack(expand = True , fill = BOTH)


# Problem here --------------------
tbox.bind("<Control-i>", comd.Ilim)
# ---------------------------------


mainloop()

推荐答案

您可以通过让函数返回字符串 "break" 来覆盖绑定.例如:

You can overwrite a binding by having your function return the string "break". For example:

def Ilim(self): # Prints How many lines are in
    info =  int(tbox.index('end-1c').split('.')[0])
    print(info)
    return "break"

如果您想完全删除所有绑定(包括允许您插入字符的绑定)，这很容易实现.所有绑定都与绑定标签"(或绑定标签")相关联.如果删除绑定标签，则删除绑定.

If you want to completely remove all bindings (including the bindings that allow you to insert characters), that can be easily accomplished. All of the bindings are associated with a "bind tag" (or "bindtag"). If you remove the bindtag, you remove the bindings.

例如，这将删除所有默认绑定:

For example, this removes all of the default bindings:

    bindtags = list(tbox.bindtags())
    bindtags.remove("Text")
    tbox.bindtags(tuple(bindtags))
