I am working with GTK 1.2.10, on Linux 2.4.18 (Red Hat 9.0). I am attempting to create a GTK window through the JNI (see code attached below), and I receive the following assertion failure during execution:
(<unknown>:6338): Gtk-CRITICAL **: file gtkwindow.c: line 794 (gtk_window_new): assertion `type >= GTK_WINDOW_TOPLEVEL && type <= GTK_WINDOW_POPUP' failed
A series of other assertions subsequently fail, all seemingly because *mShell is null.
I'm creating the window with:
static GtkWidget *mShell = NULL;
[snip]
mShell = gtk_window_new (GTK_WINDOW_POPUP);Why does this assertion fail?
Thanks in advance!
