I have a notebook with a treeview on each page. I'm trying to reference
a treeview on a notebook tab when it is clicked and compare it to
another treeview on another tab; I'm using the "switch-page" signal.
The treeviews are in vbox's in the tabs and I can't seem to get to the
one on the tab that was clicked. The callback is like this . . .
void
on_ipm_notebook1_switch_page (GtkNotebook *notebook,
GtkNotebookPage *page,
guint page_num,
gpointer user_data)
{
GtkWidget *tv=(GtkWidget *)user_data;
/* the treeview is in c_page */
GtkWidget *c_page=gtk_notebook_get_nth_page(notebook, page_num);
}
How would I get the treeview that's on the c_page? Is there a way to
send more than one object in with user_data? user_data doesn't seem to
like pointer-to-pointer (GtkWidget **tv) data.
Also, what can you do with the GtkNotebookPage object? I don't see why
this is passed in since there doesn't seem to be a way to use it.
Thanks in advance,
--dhk
