[英]Webkit threads with PyGObject on Gtk3
我試圖在與gtk主線程不同的線程上加載webkit視圖。
我看到了示例PyGTK,Threads和WebKit
我稍微修改了支持PyGObject和GTK3:
from gi.repository import Gtk
from gi.repository import Gdk
from gi.repository import GObject
from gi.repository import GLib
from gi.repository import WebKit
import threading
import time
# Use threads
Gdk.threads_init()
class App(object):
def __init__(self):
window = Gtk.Window()
webView = WebKit.WebView()
window.add(webView)
window.show_all()
#webView.load_uri('http://www.google.com') # Here it works on main thread
self.window = window
self.webView = webView
def run(self):
Gtk.main()
def show_html(self):
print 'show html'
time.sleep(1)
print 'after sleep'
# Update widget in main thread
GLib.idle_add(self.webView.load_uri, 'http://www.google.com') # Here it doesn't work
app = App()
thread = threading.Thread(target=app.show_html)
thread.start()
app.run()
Gtk.main()
結果是一個空窗口,“睡眠后”打印永遠不會執行。 idle_add調用不起作用。 唯一的工作部分是在主線程上發表評論的電話。
我需要在gdk之前使用GLib.threads_init()。
像這樣:
from gi.repository import Gtk
from gi.repository import Gdk
from gi.repository import GObject
from gi.repository import GLib
from gi.repository import WebKit
import threading
import time
# Use threads
GLib.threads_init()
class App(object):
def __init__(self):
window = Gtk.Window()
webView = WebKit.WebView()
window.add(webView)
window.show_all()
#webView.load_uri('http://www.google.com') # Here it works on main thread
self.window = window
self.webView = webView
def run(self):
Gtk.main()
def show_html(self):
print 'show html'
time.sleep(1)
print 'after sleep'
# Update widget in main thread
GLib.idle_add(self.webView.load_uri, 'http://www.google.com') # Here it doesn't work
app = App()
thread = threading.Thread(target=app.show_html)
thread.start()
app.run()
Gtk.main()
