Yes, now is failing to compile with recent gtk (since Fedora 10)

I do not get the graph widget. I only get empty space of the requested size. The code i try to use is:
---code begin---
...
    pmain_widgets->databox = gtk_databox_new ();
    gtk_widget_set_size_request (pmain_widgets->vbox, 620, 300);
    gtk_databox_create_box_with_scrollbars_and_rulers
         (&pmain_widgets->databox, &pmain_widgets->table,
                               TRUE, TRUE, TRUE, TRUE);
    gtk_box_pack_start (GTK_BOX (pmain_widgets->vbox), 
                      pmain_widgets->table, TRUE, TRUE, 0);
...
    gtk_databox_set_total_limits (
                 GTK_DATABOX (pmain_widgets->databox),
                 -1000.0, 5000.0, -10000.0, 23000.0);
    gtk_databox_auto_rescale (GTK_DATABOX (pmain_widgets->databox),
                                          0.05);
...
---code end---
I suspect that the problem is caused by the glade used to design the dialogs. Another possibility is that I use wrong variables in the code above.
The main program window is created by create_analyzer_viewer, but is almost empty and in another position on the screen. Only widgets' backgrounds are displayed as rectangles. The window is moved to final position and its content is displayed after entering gtk_main.

I tried to insert the code from examples/basics.c at the begin of create_analyzer_viewer and I got a separate window with a graph as expected.
