Get the selected tab in a enthought traits application

[petmertens]

Hi,

I have a traits application with a tabbed group:

Group(
Group(label="a", dock='tab'),
Group(label="b", dock='tab'),
layout='tabbed')

Beneath the tabbed group, there is button which should perform some action 
depending on the selected tab.
So I would like to know which of both tabs, 'a' or 'b', is selected (i.e. 
active).

Any ideas?

Thanks

I started using traits a couple of months ago and I really like it.

Traits provides a framework which creates a UI based on your data structures. 
Using some "hints" you can do anything you want. Just check out their website 
and try the examples.
Even creating an executable out of it is quite easy using bbfreeze.

The "negative" thing about is that the user group doesn't seem to be very 
large. In other words: if you get stuck on something, there aren't many people 
to help you. This however should not prevent you from using traits.

Just try it and let me know what you think about it.

Did you consider using xlrd and xlwt?
I guess these package provide a solution to your problem.

Here's the answer:

from enthought.traits.api import HasTraits, Str, List, Button, Any
from enthought.traits.ui.api import View, Item
from enthought.traits.ui.api import ListEditor

class A(HasTraits):
   StringA = Str

   view = View(Item('StringA'))

class B(HasTraits):
   StringB = Str

   view = View(Item('StringB'))

class C(HasTraits):
   MyList = List(HasTraits)
   MyButton = Button(label="Test")
   SelectedTab = Any

   def _MyButton_fired(self):
  if self.SelectedTab == self.MyList[0]:
 print self.MyList[0].StringA
  if self.SelectedTab == self.MyList[1]:
 print self.MyList[1].StringB

   view = View(Item('MyList', style='custom', show_label=False, 
  editor=ListEditor(use_notebook=True, deletable=False, 
dock_style='tab', selected='SelectedTab')),
   Item('MyButton', show_label=False))

a = A()
b = B()
c = C()
c.MyList = [a, b]

c.configure_traits()
