Python-如何将文本写入GTK+ Vte终端小部件？

Question

我正在尝试使用一个Vte终端部件来显示我的python脚本中的文本。

我不设置工作目录或模拟器，我只想要一个处理文本和ansi转义序列的空终端

我有这段代码，它在python2.7中工作：

import gi
gi.require_version('Gtk', '3.0')
gi.require_version('Vte', '2.91')

from gi.repository import Gtk, Vte
from gi.repository import GLib
import os

terminal     = Vte.Terminal()
terminal.spawn_sync(
    Vte.PtyFlags.DEFAULT,
    None,
    [],
    [],
    GLib.SpawnFlags.DO_NOT_REAP_CHILD,
    None,
    None,
    )

win = Gtk.Window()
win.connect('delete-event', Gtk.main_quit)
win.add(terminal)
win.show_all()

terminal.feed('hello') #string to display

Gtk.main()

但是它不能在python 3.5中工作，我得到的只是一个空白的终端。

下面是显示文本的正确方法：

import gi
gi.require_version('Gtk', '3.0')

from gi.repository import Gtk, Gdk, GLib
import os

textview = Gtk.TextView()
textview.set_name("TextView")
buf = Gtk.TextBuffer()
textview.set_buffer(buf)
buf.set_text("This is a test message\n")

style_provider = Gtk.CssProvider()

css = """
#TextView{
    background-color: black;
}
"""
style_provider.load_from_data(bytes(css.encode()))
    Gtk.StyleContext.add_provider_for_screen(
    Gdk.Screen.get_default(), style_provider,
    Gtk.STYLE_PROVIDER_PRIORITY_APPLICATION
    )

for color in ("red", "yellow", "green", "blue", "white"):
    buf.insert_markup(
        buf.get_end_iter(),
        '<span color="{:s}">This is a test message</span>\n'.format(color),
         -1)

win = Gtk.Window()
win.connect('delete-event', Gtk.main_quit)
win.add(textview)
win.show_all()


Gtk.main()

顺便说一句，这要容易得多。

编辑：包含颜色。

嗨，我希望这对我使用python3.7下的vte.Terminal的迷你版本有所帮助。

这种旧的格式

terminal.spawn_sync

现在不受欢迎了。

因此，您可以使用更新的格式，如下面的完整源代码和terminator3链接：https://gitlab.com/raffiki-python/terminator-py3/-/blob/master/miniTerm.py
