Hello. Thanks for the reply. What I need now is a way to trigger an event from the WebKitWebView or the WebKitWebFrame Gtk+ object instead of calling the invalidate_rect(). I've noticed the call to containingWindow() which returns a GtkWidget. The problem is I don't know if that's the gtk+ webview widget. Please help.

hi, This happens when you call a gdk_window_invalidate_rect on the page window (webView->window). This api implies the window is dirtied and needs refresh for the specified rectangle area.

you can check WebCore/platform/gtk/ScrollViewGtk.cpp update* which are called by the rendering engine.

regards, Zaheer

What I couldn't find out what actually triggers this function. Any ideas.
