[GTK] Virtual python shell with Vte.Pty.spawn_async()

[jiri]

I would like add virtual python shell with Vte to my GTK3.0 python3 app and I am able to do this with spawn_sync() method, but this method is deprecated, so I would like to do it with preferred way with Vte.Pty.spawn_async(), but I dont understeand how .... I tried some parts of code, but with no luck. Pleas, give me someone some working code in python. For example, I tried variant like this:

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

class TheWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="GTK3 IDE")

        self.box = Gtk.HBox(spacing=6)
        self.add(self.box)

        self.terminal = Vte.Terminal()
        self.terminal.pty_new_sync(Vte.PtyFlags.DEFAULT)

        self.pty = Vte.Pty()
        self.pty.new_sync(Vte.PtyFlags.DEFAULT, None)
        self.pty.spawn_async(
            None,
            ["/bin/python"],
            None,
            GLib.SpawnFlags.DO_NOT_REAP_CHILD,
            None,
            None,
            -1
            )
        self.terminal.set_pty(self.pty)

Thanks a lot for any help.

I find some mistakes in my code, now it is working great, there is final solution:

import gi
gi.require_version('Gtk', '3.0')
gi.require_version('Vte', '2.91')
from gi.repository import Gtk, Vte, GLib, Pango, Gio

class TheWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="GTK3 IDE")
        self.set_default_size(600, 300)

        terminal = Vte.Terminal()
        #pty = terminal.pty_new_sync(Vte.PtyFlags.DEFAULT)
        pty = Vte.Pty.new_sync(Vte.PtyFlags.DEFAULT)
        terminal.set_pty(pty)

        pty.spawn_async(
            None,
            ["/bin/python"],
            None,
            GLib.SpawnFlags.DO_NOT_REAP_CHILD,
            None,
            None,
            -1,
            None,
            self.ready
            )

        #self.terminal.get_pty(self.pty)

        box = Gtk.Box(orientation=Gtk.Orientation.VERTICAL)

        scroller = Gtk.ScrolledWindow()
        scroller.set_hexpand(True)
        scroller.set_vexpand(True)
        scroller.add(terminal)
        box.pack_start(scroller, False, True, 2)
        self.add(box)

    def ready(self, pty, task):
        print('pty ', pty)


win=TheWindow()
win.connect('destroy', Gtk.main_quit)
win.show_all()
Gtk.main()

with your code you can not execute a command

try

import gi
gi.require_version('Gtk', '3.0')
gi.require_version('Vte', '2.91')
from gi.repository import Gtk, Vte, GLib, Pango, Gio
import os
 
class TheWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="GTK3 IDE")
        self.set_default_size(600, 300)
 
        terminal = Vte.Terminal()
        pty = Vte.Pty.new_sync(Vte.PtyFlags.DEFAULT)
        terminal.set_pty(pty)
 
        terminal.spawn_sync(
            Vte.PtyFlags.DEFAULT,
            os.environ['HOME'],
            ["/bin/sh"],
            [],
            GLib.SpawnFlags.DO_NOT_REAP_CHILD,
            None,
            None,
            )
 
        box = Gtk.Box(orientation=Gtk.Orientation.VERTICAL)
 
        scroller = Gtk.ScrolledWindow()
        scroller.set_hexpand(True)
        scroller.set_vexpand(True)
        scroller.add(terminal)
        box.pack_start(scroller, False, True, 2)
        self.add(box)
 
    def ready(self, pty, task):
        print('pty ', pty)
 
 
win=TheWindow()
win.connect('destroy', Gtk.main_quit)
win.show_all()
Gtk.main()
