Hi,
In the following script when I select ‘page 2’ in the notebook,
the hello button isn’t shown. If I switch tabs, then show ‘page 2’,
for a second time, the button is shown.
Am I doing something wrong?
Martin.
require ‘gtk2’
Gtk.init
win = Gtk::Window.new
notebook = Gtk::Notebook.new()
table = Gtk::Table.new(1,1)
scrolled_win = Gtk::ScrolledWindow.new
scrolled_win.add_with_viewport( table )
notebook.append_page( Gtk::Label.new(“empty”), Gtk::Label.new(“page 1”))
notebook.append_page( scrolled_win, Gtk::Label.new(“page 2”))
win.add( notebook )
win.show_all
notebook.signal_connect(“switch-page”){|w,page,page_num|
if( page_num==1)
table.resize(1,1)
button = Gtk::Button.new(“hello”)
table.attach_defaults( button, 0,1, 0,1 )
button.show
end
}
Gtk.main

Switch to using signal_connect_after. Otherwise, you end up doing
something before Gtk::Notebook does, which makes it all sorts of funky
for some reason:
notebook.signal_connect_after(‘switch-page’) { |w,page,page_num| blah }
-pete
