Dos problemas

[IamEdo]

Holas
para la 1 con gtk.Entry() la tienes
aqui un codigo de un navegador muuuuy sencillo que encontre por ahi

Código Python:

import sys
import gtk
import webkit
 
DEFAULT_URL = 'http://www.google.com'
 
class SimpleBrowser:
 
    def __init__(self):
        self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
        self.window.set_position(gtk.WIN_POS_CENTER_ALWAYS)
        self.window.connect('delete_event', self.close_application)
        self.window.set_default_size(800, 600)
 
        vbox = gtk.VBox(spacing=5)
        vbox.set_border_width(5)
 
        self.txt_url = gtk.Entry()
        self.txt_url.connect('activate', self._txt_url_activate)
 
        self.scrolled_window = gtk.ScrolledWindow()
        self.webview = webkit.WebView()
        self.scrolled_window.add(self.webview)
 
        vbox.pack_start(self.txt_url, fill=False, expand=False)
        vbox.pack_start(self.scrolled_window, fill=True, expand=True)
        self.window.add(vbox)
 
    def _txt_url_activate(self, entry):
        self._load(entry.get_text())
 
    def _load(self, url):
        self.webview.open(url)
 
    def open(self, url):
        self.txt_url.set_text(url)
        self.window.set_title('SimpleBrowser - %s' % url)
        self._load(url)
 
    def show(self):
        self.window.show_all()
 
    def close_application(self, widget, event, data=None):
        gtk.main_quit()
 
if __name__ == '__main__':
    if len(sys.argv) > 1:
        url = sys.argv[1]
    else:
        url = DEFAULT_URL
 
    # PyWebkitGTK necesita habilitar el soporte de los hilos en PyGTK
    gtk.gdk.threads_init()
    browser = SimpleBrowser()
    browser.open(url)
    browser.show()
    gtk.main()
 

y para el 2, de gtk no se casi nada pero encontre este codigo que te serviria

Código Python:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#
import os
import sys
 
#gtk
import pygtk
if sys.platform != 'win32':
    pygtk.require('2.0')
import gtk
import gobject
 
 
class WinTest:
    """Main Window"""
 
    def __init__(self):
        """test"""
        #build the window
        self.winMain = gtk.Window()
        #set window properties
        self.winMain.set_events(
            gtk.gdk.KEY_PRESS_MASK |
            gtk.gdk.KEY_RELEASE_MASK)
        print "events=",self.winMain.get_events()
        self.winMain.connect('key-press-event', self.on_winMain_key_press)
        self.winMain.connect('key-release-event', self.on_winMain_key_press)
        self.winMain.connect('delete-event', self.on_winMain_delete_event)
        self.winMain.set_size_request(300, 400)
        self.winMain.show()
 
    def on_winMain_key_press(self, widget, event, *args):
        """handle keyboard events"""
        keyname = gtk.gdk.keyval_name(event.keyval).upper()
        if event.type == gtk.gdk.KEY_PRESS:
            if keyname == 'ESCAPE':
                self.on_winMain_delete_event()
            else:
                print "key press=", keyname
        elif event.type == gtk.gdk.KEY_RELEASE:
            print "key release=", keyname
        return False
 
    def on_winMain_delete_event(self, *args):
        """done, quit the application"""
        #exit gtk loop
        gtk.main_quit()
        return False
 
 
if __name__ == '__main__':
    #instantiate main GUI window class
    app = WinTest()
    #and... go...
    gtk.main()
