I had this problem with GChemPaint a long time ago. To solve it, I use
the "expose-event" signal for the child widget. When this signal is
fired, I check the state of the current active page, and if the
validation fails, I use gtk_notebook_set_current_page to set the active
the code is in :
gcpStandaloneApp::SetActive (gcpDocument* pDoc, GtkWidget* w) (line 963
or so).
This code is somewhat old now, so I can't remember why I could not use
the GtkNotebook signals... so there might beis a better solution ;-)
