Solved [Connecting page switching in Notebook with selection in Ctree.]

[Latevi Max LAWSON DAKU <Max Lawson chiphy unige ch>]

Hello, 

I've solved my problem by upgrading :-)

> Hello !  I'm new to using Gtk-Perl and I'm in trouble.

> I've tied together a CTree and a notebook: a selection in the $ctree
> sets the appropriate page in the $notebook through the call

>         (+) $notebook->set_page($page_num);

> in the callback function &select_row associated with signal
> 'tree_select_row':

> Users can manually switch the page. Reversely, I would like to
> update selection in $ctree according to the newly selected page:
> I've attached a callback function &switch_page to the 'switch_page'
> signal of $notebook. There:

>         (+) I retrieve the number of the new page and the
> corresponding node in the $ctree; (+) call &select_row after having
> let the callback blocked itself to avoid infinite loop.  (+)
> Finally, the callback unblocks itself at the end of the routine,
> when returning from &select_row.

> But this hack does not correctly work: first, I obtain the message
> below when switching pages in a notebook:

>         (+) Wed Jul 25 12:38:14 2001 Gtk-WARNING **: invalid cast
> from (NULL) pointer to `GtkObject' at ./adf_xwin.pl line 582.

> Line 582 is

>         (+) $notebook->set_page($page_num);

> Second, inspection of the arguments of the callback function,
> &switch_page, reveals that, for a given page, the hash reference,
> corresponding to the associated NotebookPage, changes from call to
> call, taking values in an apparently limited set. I don't believe
> it's normal ...

> I thank you in advance for your help.
