Re: enaml - focusing a widget at initialization time

Matthew Scott — 2012-05-25T15:32:33

Oops!  Thank you for pointing this out.  :)

I can confirm that using this pattern works for focusing a different widget on initialization (if using the 'qt4' backend!), until focus manipulation is exposed in an enaml API as noted at https://github.com/enthought/enaml/issues/160:

enamldef Main(MainWindow):
    Container:
        Field:
            id: field1
        Field:
            id: field2
            initialized :: 
                toolkit_widget.setFocus()

Re: enaml - focusing a widget at initialization time

Robert Kern — 2012-05-25T09:22:09

Correct, we have not exposed any focus manipulation APIs yet. I have
entered a ticket to track this:

  https://github.com/enthought/enaml/issues/160


QWidget.focusWidget() does not set the focus. It just returns the
widget with the focus.

http://qt-project.org/doc/qt-4.7/qwidget.html#id-1578ce97-cec8-4e41-b88e-5f42bca169aa

You want QWidget.setFocus() instead:

enaml - focusing a widget at initialization time

Matthew Scott — 2012-05-25T06:13:32

I'm trying to focus a widget at initialization time. 

For example, I have the following structure in my .enaml file.  The first widget to gain focus is 'csv_editor'.  However, I want 'field' to be focused.

enamldef Main(MainWindow):
    Container:
        Label:
            text = 'CSV editor'
        Label:
            text = '(first row is column name/title mapping)'
        TextEditor:
            id: csv_editor
            initialized :: 
                set_text(DEFAULT_CSV)
        Label:
            text = 'FilterField control'
        Field:
            id: field
        TableView:
            id: filter_table
            item_model = ListModel([])
            vertical_header_visible = False
            visible << field.value.strip() != ''

I couldn't find anything in enaml.components that indicated an attribute or method that could be used to set focus.  

However I did track down 'toolkit_widget', and that lets me call upon Qt's 'focusWidget()' method:

            initialized ::

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()

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 'v

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

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.

I'm looking forward to learning about encore and enami.  Besides the

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.

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.

Adam Hughes — 2012-05-16T20:44:00

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

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 :)
