What I find is that the situation is the same as in gtk 3.16.4: if I use the new (in 3.16) special function gtk_notebook_detach_tab() then my test case runs OK; otherwise (using gtk_container_remove() for the outgoing notebook tab) it segfaults, as in gtk 3.14 and 3.16 (but not 3.12 or earlier). -- Allin Cottrell Department of Economics Wake Forest University ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Hello all,
My app has a collection of objects which can be viewed either
individually or in a tabbed viewer based on GtkNotebook. When objects
are being viewed in the latter way, the user is supposed to be able to
drag an object out of the tabbed viewer, with the effect of giving it
its own window.
This works fine with gtk 2.24.28, but I'm getting a segfault with the
same code on gtk 3.16.4. This looks like a gtk bug, but maybe I'm
doing something wrong and before I file a report I'd be grateful if
anyone could take a look at minimal test case below.
The idea is to start the program, switch to the second page in the
notebook, and try dragging the tab onto the root window. With gtk3
I get a crash, preceded by the message
Gtk-CRITICAL **: gtk_widget_get_frame_clock: assertion 'GTK_IS_WIDGET
(widget)' failed
Here's the minimal code:
#include gtk/gtk.h
/* Minimal test case for dragging a tab out of a
notebook onto the root window
Allin Cottrell cottr...@wfu.edu, 2015-07-06
*/
static GtkNotebook *detach_tab_callback (GtkNotebook *book,
GtkWidget *page,
gint x, gint y,
gpointer data)
{
GtkWidget *window;
gint pgnum;
g_object_ref(page);
pgnum = gtk_notebook_page_num(GTK_NOTEBOOK(book), page);
gtk_notebook_remove_page(GTK_NOTEBOOK(book), pgnum);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_container_add(GTK_CONTAINER(window), page);
g_object_unref(page);
gtk_widget_show_all(window);
/* return NULL since we're not adding the detached
tab to another GtkNotebook */
return NULL;
}
int main (int argc, char **argv)
{
GtkWidget *window, *notebook, *child;
gtk_init(argc, argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

gtk_main_quit, NULL);
