Re: GtkNotebook with action on click of special tab

Hi Bernhard

Not sure what you are trying to do.

Gtk_Notebook is a nice feature.  What I found works is to process the  
"switch-page" signal.

Generally I setup each page prior to displaying it and associate my own 
control data with each page.  (From memory GTK does not bother to 
display blank pages, which can be confusing)

Then I display the page I want.

If the user tabs to another page, I let gtk handle the page switch and 
handle input from the selected page as appropriate, using my own control 
data to do this.

I suppose there is a case for writing my own extention for gtk-notebook, 
a derived class, but  have not tried this, as I prefer to keep my own 
data completely separate from GTK.

The only thing to watch is that if you delete a tabbed page, then the 
page index for all higher pages decrements.  Just allow for this when 
switching your own control data

Hope this helps
