GTK3标签滚动条Python

Question

Here is notebook code with gtk3 python.

#!/usr/bin/python
# -*- coding: utf-8 -*-

from gi.repository import Gtk

window = Gtk.Window(title="Notebook")
window.set_default_size(600, 360)
window.connect("destroy", lambda q: Gtk.main_quit())

notebook = Gtk.Notebook()
window.add(notebook)

notebook.set_tab_pos(Gtk.PositionType.LEFT)

label0 = Gtk.Label() # need here scrollbar
label1 = Gtk.Label() # need here scrollbar

label0.set_text("First text inside")
label1.set_text("Second text inside")

notebook.append_page(label0)
notebook.append_page(label1)

notebook.set_tab_label_text(label0,"First tab title")
notebook.set_tab_label_text(label1,"Second tab title")

notebook.set_tab_reorderable(label1, False)

label0.set_alignment(0.0,0.0)
label1.set_alignment(0.0,0.0)

window.show_all()
Gtk.main()

How to add scrollbar on Labels? Not in main window or main container, but only in labels, where are "First Text inside, Second text inside" labels.

Answer 1

Gtk.Notebook doesn't support that. If there are too many tab labels to fit in the space, then it will add arrows for paging through the tabs; I'm assuming that's not what you want.

Instead, use Gtk.StackSidebar with Gtk.Stack (GTK 3.16 or later). If you have 3.10 or later, you can still use Gtk.Stack but you will have to build your own replacement for Gtk.StackSidebar which you can probably do quite easily with Gtk.ListBox .
