How to handle tab selection in Gtk# Notebook widget?

Question

I thought it will be easy, but...

// An empty Notebook defined in Stetic designer and created in generated code
Notebook tabs = this.TabsContainer;

tabs.SelectPage += (o, args) => {
    Application.Quit();
};

// Then I add some pages in code by calling tabs.AppendPage(...)

With this code, when I switch Notebook pages back and forth by clicking at tabs, event is obviously not handled. I tried also using other event (FocusTab), but handler is never called anyway. What have I missed?

Answer 1

I looked at the sources of gtk+ and it seems that the select-page signal is defined, but is never emitted (I will probably file a bug to mark it as deprecated).

I also noticed that the signal switch-page (which you should be able to subscribe via the event SwitchPage) is certainly emitted, so this should work (please report back if it doesn't and I'll take another look).
