Traits UI doesn't parent things properly when using kind='subpanel' on
Qt. This is how to work around it:

  ui = ns.edit_traits(parent=ns.frameWidget,kind='subpanel')
  ui.control.setParent(ns.frameWidget)

Hi,

I'm trying to add a traits editor to an existing qt tab widget. The
following bit of code adds a tab but the traits editor is not visible.
The line commented out pops up a standard editor separate from the
main window. Any idea what I'm doing wrong?

Thanks,
Chris

            ns =
NumericalSolution.NS_base(so,pList,nList,sList,opts,simFlagsList)
            ns.frameWidget = vtkViewers.QtGui.QFrame(vtkViewers.g.mainWindow)
            ns.hbox = vtkViewers.QtGui.QHBoxLayout()
            ns.frameWidget.setLayout(ns.hbox)
            vtkViewers.g.tabWidget.addTab(ns.frameWidget,"NumericalSolution")
            vtkViewers.g.tabWidget.setCurrentWidget(ns.frameWidget)
            ns.edit_traits(parent=ns.frameWidget,kind='subpanel')
            #ns.edit_traits()

Opps, actually found this in the archive

Should have dug for a few more minutes before emailing, thought the hour I spent was enough to justify bugging everyone....

trait views

Ross Harder — 2012-05-17T22:41:16

Hi,

I'd like to have a traited class define several different views of it's traits but also keep the default view of all of it's traits intact without explicitly defining that view (the real class I am trying to do this with has many traits).   Is there a simple way to keep the default, show everything, view around and also define custom views that can be incorporated into the view of a class that contains an instance of the class with tons of traits?

 Below is a simplification of what I have been trying.  

from traits.api import HasTraits, Float, Instance, Int
from traitsui.api import View, Item, InstanceEditor


class Params(HasTraits):
  thing1=Float(1.0)
  thing2=Float(2.0)
  thing3=Int(3)

  l=[Item('thing2')]
  view1=View(l)

  def default_traits_view(self):
    alltraits=[]
    for k,v in self.__dict__.iteritems():
      print k, type(self.__dict__[k]) , type(self.__dict__[k]).__name__=='int'
      alltraits.append(Item(str(k)))
    self.view_all=View(alltraits)
    return 'view_all'

  def get_1thingview(self):
    view_1thing=View(Item('thing2'))
    return view_1thing

class Component(HasTraits):

  s=Float(2.3)
  p=Instance(Params)

  view=View( Item('s'), Item(name='p', style='custom') )
#  view=View( Item('s'), Item(name='p', style='custom') )
#  view=View( Item('s'), Item(name='p', style='custom', editor=InstanceEditor(view='view1')) )

  def __init__(self):
    self.p=Params()


if __name__=='__main__':
  c=Component()
  print c.p.default_traits_view()
  c.configure_traits()

Re: ANN: ETS 4.2 released

Eraldo Pomponi — 2012-05-17T08:11:54

Thanks a lot to all of you for your effort to provide us with this amazing
set of tools ....
I'm eager to learn more about Enaml (mostly) and Encore .....

Just a bit more: for Enaml there is also the talk of Chris Colbert posted
in your blog:
http://blog.enthought.com/page/4/

while the webinar
http://www.enthought.com/repo/epd/webinars/2011-12DeclarativeUIsEnaML/ is
not accessible if
you don't have an epd account (I guess)

Cheers,
Eraldo

I would add that there is also a webinar about enaml though a few months

The basic documentation for encore is on out docs site:

http://docs.enthought.com/encore/

There are docs on Enaml there as well, but they are about 3 months out of
date, and the API has changed a lot since then - the examples are a better
place to go for how-to.

Re: ANN: ETS 4.2 released

Adam Hughes — 2012-05-17T01:57:04

I'm looking forward to learning about encore and enami.  Besides the
examples on github, is there yet any form of tutorial on these new projects?

ANN: ETS 4.2 released

Ilan Schnell — 2012-05-17T01:39:27

Hello all,

I'm happy to announce that ETS 4.2 is now released.
This release adds two new projects encore and enaml
to ETS.

As usual, for convenience, I've created a single (44MB)
tarball which contains the source tarballs of all proejcts:
http://www.enthought.com/repo/ets/ALLETS-4.2.0.tar

EPD 7.3, which will be released next Wednesday, May 23rd,
will feature this ETS release.

Oh I see, the hidden installers don't come with a subscription because the
subscription also gives access to the webinars and other features, correct?

Indeed. If you subscribe, you will receive a password which can be used
with your existing installation.

Parenthetically, let me also mention that many Linux EPD users simply
install EPD into a directory to which they have full permissions.

Re: enpkg error

Adam Hughes — 2012-05-16T21:56:43

Yes this is probably the problem.  When I installed EPD, I had put in a
request through academic use, and was sent a link to hidden installers.
Through this I never had to make an account for the repo.  Is it possible
to make a repo account after the fact?  If not, I can just reinstall EPD
7.2 fresh.

Re: enpkg error

Robert Kern — 2012-05-16T20:57:16

Ah, you probably don't have a ~root/.enstallerrc, so it's just looking
at the free repos. You can re-enter your authentication information as
root:

  $ sudo /usr/local/EPD/bin/enpkg --userpass

Alternately, I think

  $ sudo -E enpkg epd

will keep your current environment, but I could be misreading the man page.

Re: enpkg error

Adam Hughes — 2012-05-16T20:44:00

Thanks Robert.  I tried putting the full path in. Any idea why it would say
the following:

glue< at >glue-pc:~/Dropbox/Curve_Analysis_Traits/Curve_analysis_traits_v3$ sudo
/usr/local/EPD/bin/enpkg epd
prefix: /usr/local/EPD
No distribution found for requirement 'epd'.

Re: Traits wrapper for pandas

Adam Hughes — 2012-05-16T20:38:08

Ah I see.  Well, I'll read over the document Jonathan sent me and see how
feasible it would be to make a HasTraits subclass.  If there are any
developers that would be interested in helping and actually have spare
time, that would be great :)

Re: enpkg error

Robert Kern — 2012-05-16T20:35:23

Depending on how sudo is configured on your system and for your user,
the environment that the underlying command runs in may be that of
root rather than your user. Consequently, it may not have the same
$PATH. Running either

  $ sudo `which enpkg` epd

or

  $ sudo /usr/local/EPD/bin/enpkg epd

should work. You may want to look into setting your root environment
to have EPD's bin directory on $PATH, too.

Re: Traits wrapper for pandas

Corran Webster — 2012-05-16T20:23:40

Hi Adam,

The Array trait can't avoid these issues, and so doesn't even attempt to
listen to changes in the underlying memory - that's why you can't set a
listener on 'myarray_items' or similar for an Array trait.

Re: Traits wrapper for pandas

Adam Hughes — 2012-05-16T20:19:22

Thanks Corran.  I had feared that something along these lines may be an
issue.  Although I would be interested in making my own Traits subclasses,
I don't think I have the experience to do something like that.  And I would
totally be clueless about having any control at the C-level.  I read that
pandas does have a lot of optimizations at the C-level, so I really
wouldn't know what's going on there.  How does the Array trait avoid these
issues, since numpy is also optimized at the C code level?
