Question

I am facing the problem to need tabs in a pygtk app. Pretty much just like gedit has, but without any per-child widget content.
I’ve come across gtk.Notebook, but that requires me to put a widget for each tab, which I don’t want.

The reason is, that I have one widget, but would only like to updates its content based on which tab is selected.

Any hints on how to do that?
My idea so far would be to just add some invisible widget for each tab and then connect to the select-page signal. Which widget could I use as invisible widget, or is there a better/alternative way of achieving my goal?

The invisble widget idea works. But not with gtk.Invisible (this just crashes), but with gtk.HBox() or any other thing that seems empty.

self.notebook.append_page(gtk.HBox(), gtk.Label("title"))

Now if I want to display stuff inside the tab actually, I can use reparent to move the widget to the current tab like this.

class Tab(gtk.HBox):
    def __init__(self, child):
        self.child = child

self.notebook.append_page(Tab(myWidget), gtk.Label("title"))

def pageSelected(self, notebook, page, pagenum):
    box = notebook.get_nth_page(pagenum)
    box.child.reparent(box)
