Question

我需要得到showY以及showX我可以改变顺序但情况比这更复杂。

from Tkinter import *
root = Tk()
text = Text(master=root)
text.pack()

def showX(event):
    print 'handle 1'
    # return """I need to return something that permits showY being trigged
           # but the character x not being echoed over the text area.
           # 'break' avoids the character being echoed but avoids showY being hand           led"""
    return 'break'

def showY(event):
    print 'handle 2'

# it seems that even with add=True tkinter doesnt match Key-X as Shift-X.
# they are separate events.
text.bind('<Key-x>', showY, add=True)
text.bind('<KeyPress-x>', showX, add=True)

Answer 1

#I need to return something that permits showY being trigged
# but the character x not being echoed over the text area.

我认为你的意思不是从showX函数调用showY。解决方法是使用第三个函数，假设程序指示两个函数是必需的，因为你只需要一个showY选项。

from Tkinter import *
root = Tk()
text = Text(master=root)
text.insert(END, "abc")
text.pack()

def show_both(event):
    showX(event)
    showY(event)
    return 'break'

def showX(event):
    print 'handle 1'

def showY(event):
    print 'handle 2'

##text.bind('<Key-x>', showY, add=True)
text.bind('<KeyPress-x>', show_both, add=True)
root.mainloop()

避免在tkinter中的文本小部件上回显字符，但后续句柄被调用
