When I trying to generate a ivtk GUI interface by:

from tvtk.tools import ivtk

win = ivtk.IVTKWithCrustAndBrowser()
win.open()

I get an error:

Traceback (most recent call last):

return self.browser.ui.control
AttributeError: 'PipelineBrowser' object has no attribute 'ui'

And when I view the source code, the class PipelineBrower.ui doesn't exist, instead, it changes to ._ui

After modifing file tvtk\tools\ivtk.py line 209

return self.browser.ui.control

to

return self.browser._ui.control

That works

Another bug you can see is that pipeline browser is poped up rather than embeded in the TVTK Scene GUI, in order to fix this, I have to coded like this:

from tvtk.tools import ivtk

win = ivtk.IVTKWithCrustAndBrowser()
win.open()

# fix this pop up bug
dialog = win.control.centralWidget().widget(0).widget(0)
from pyface.qt import QtCore
dialog.setwindowFlags(QtCore.Qt.WindowFlags(0x00000000))
dialog.show()

May you help to fix these in the source code?

Thanks!
