我正在用Python编写一个带有Tkinter UI的程序.我想要一个没有标题栏的小窗口.此窗口必须接收键盘输入.我不挑剔这是以Entry小部件的形式还是只是绑定到KeyPress.overrideredirect(True)通常是标题栏被禁用的方式.不幸的是,(除了在Windows中),这似乎阻止了许多事件被接收.我写了这段代码来说明问题:

#!/usr/bin/env python
from __future__ import print_function
import Tkinter

class AppWindow(Tkinter.Tk):
    def __init__(self, *args, **kwargs):
        Tkinter.Tk.__init__(self, *args, **kwargs)
        self.overrideredirect(True)
        self.geometry("400x25+100+300")

        titleBar = Tkinter.Frame(self)
        titleBar.pack(expand = 1, fill = Tkinter.BOTH)

        closeButton = Tkinter.Label(titleBar, text = "x")
        closeButton.pack(side = Tkinter.RIGHT)
        closeButton.bind("<Button-1>", lambda event: self.destroy())

        self.bind("<KeyPress>", lambda event: print("<KeyPress %s>" % event.char))
        self.bind("<Button-1>", lambda event: print("<Button-1>"))
        self.bind("<Enter>", lambda event: print("<Enter>"))
        self.bind("<Leave>", lambda event: print("<Leave>"))
        self.bind("<FocusIn>", lambda event: print("<FocusIn>"))
        self.bind("<FocusOut>", lambda event: print("<FocusOut>"))

if __name__ == "__main__":
    app = AppWindow()
    app.mainloop() …
