GtkSpinButton disabled by default in Glade

Question

I added GtkSpinButton to my dialog from Glade and it is disabled by default:

What should I do to make arrows enabled?

Answer 1

You need to configure the GtkSpinButton with the Adjustment object as follows (example values):

adj = gtk.Adjustment(1, 1, 99, 1, 1, 1)
spinBtn = self.builder.get_object("spinbutton1")
spinBtn.configure(adj, 1, 0)
