PyGtk：我不能使用vte库函数吗？

问题描述

我正在尝试将命令发送到Vte终端，但我一直收到相同的错误。另外，我在互联网上找不到其他工作示例。由于目前我的代码尚不完整，因此向您展示了stackoverflow中的示例。它给出了相同的错误。

错误消息：

File "~/basic-terminal/terminal.py",line 52,in InputToTerm
    self.terminal.Feed_child(self.command,length)
TypeError: Vte.Terminal.Feed_child() takes exactly 2 arguments (3 given)

代码：

from gi.repository import Gtk,GObject,Vte
#GObject is not required. I just import it everywhere just in case.
#Gtk,Vte,and GLib are required.
from gi.repository import GLib
import os
#os.environ['HOME'] helps to keep from hard coding the home string.
#os is not required unless you want that functionality.

class TheWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self,title="inherited cell renderer")
        self.set_default_size(600,300)
        self.terminal     = Vte.Terminal()
        self.terminal.fork_command_full(
                Vte.PtyFlags.DEFAULT,#default is fine
                os.environ['HOME'],#where to start the command?
                ["/bin/sh"],#where is the emulator?
                [],#it's ok to leave this list empty
                GLib.SpawnFlags.DO_NOT_REAP_CHILD,None,#at least None is required
                None,)
        #Set up a button to click and run a demo command
        self.button = Gtk.Button("Do The Command")
        #To get the command to automatically run
        #a newline(\n) character is used at the end of the
        #command string.
        self.command = "echo \"Sending this command to a virtual terminal.\"\n"
        command = Gtk.Label("The command: "+self.command)
        self.button.connect("clicked",self.InputToTerm)
        #end demo command code

        #set up the interface
        Box = Gtk.Box(orientation=Gtk.Orientation.VERTICAL)
        Box.pack_start(self.button,False,True,0)
        Box.pack_start(command,1)
        #a scroll window is required for the terminal
        scroller = Gtk.ScrolledWindow()
        scroller.set_hexpand(True)
        scroller.set_vexpand(True)
        scroller.add(self.terminal)
        Box.pack_start(scroller,2)
        self.add(Box)

    def InputToTerm(self,clicker):
        #get the command when the button is clicked
        length = len(self.command)
        #A length is not required but is the easiest mechanism.
        #Otherwise the command must be null terminated.
        #Feed the command to the terminal.
        self.terminal.Feed_child(self.command,length)


win = TheWindow()
win.connect("delete-event",Gtk.main_quit)
win.show_all()
Gtk.main()

我该怎么办？为什么我总是不断收到此错误？

解决方法

解决了问题。命令已更改。您也可以通过这种方式解决您的问题：）

self.terminal.feed_child(self.command.encode("utf-8"))
