I'm trying to create Qt application with Cef browser working on Linux (Debian Wheezy) Versions: Qt 5.5, Cef 1547 Basically, I have QWidget with following browser initialization code: CefwindowInfo info; QWindow* win = new QWindow(); this->layout()->addWidget(QWidget::createWindowContainer(win)); info.SetAsChild((CefWindowHandle)win->winId()); CefBrowserHost::CreateBrowser(info, ...); This code causes Segmentation fault exception with following callstack 0> g_type_check_instance_cast 1> CefBrowserHostImpl::PlatformCreateWindow() 2> ?? If I comment out the line with info.SetAsChild(..) , everything works as expected save that Cef is launched in separate window, while I need it to be integrated in my Qt application. Any ideas what am I doing wrong?

Actually, I've managed to make it work. Just in case, if someone will need it in future: GtkWidget* gtkWin = gtk_window_new(GTK_WINDOW_TOPLEVEL); GtkWidget* parentView = gtk_vbox_new(FALSE, 0); GtkContainer* container = (GTK_CONTAINER(gtkWin)); gtk_container_add(container, parentView); gtk_window_set_position(GTK_WINDOW(gtkWin), GTK_WIN_POS_CENTER); gtk_widget_show_all(GTK_WIDGET(gtkWin)); GdkWindow* w = gtk_widget_get_window(parentView); XID t = gdk_x11_drawable_get_xid(w); WId wid = (WId) t; QWindow* win = QWindow::fromWinId(wid); setLayout(new QGridLayout()); QWidget* widget = QWidget::createWindowContainer(win); this->layout()->addWidget(widget); info.SetAsChild(parentView); Basically, I've created my own GTK window, passed the reference on this window to CEF, and placed it into Qt widget using QWindow::fromWinId().
