open_file question

I’m having trouble piecing together the correct syntax for the filter keyword of open file.

 

from enthought.traits.ui.file_dialog  import open_file

open_file(filter=’Text file (*.txt)|*.txt’)

 

…selects no files.

 

open_file(filter=[’Text file (*.txt)|*.txt’,])

 

…selects text files.

 

open_file(filter=[’Text file (*.txt)|*.txt’, ’Python (*.py)|*.py’])

 

…selects only text files, and…

 

open_file(filter=[’Python (*.py)|*.py’, ’Text file (*.txt)|*.txt’,])

 

…selects only Python files.

 

Can someone clue me how to apply multiple, logically or’ed filters?  (A pull-down selection among filters would be OK, too.)

 

Thanks much,

Mike

Try removing the vtkCommonPython.pyc file from the library.zip.

I had completely forgotten about this axes class.  A long while ago this 
was ported from paraview to VTK but at that time since it was only 
available in VTK-cvs I did not wrap it.  I'll have to figure out which 
release has this available and wrap it suitably.  I have no idea when I 
will get around to it though.  Maybe next weekend.

I'm pretty sure it's supposed to be there. Like zipped eggs, there
needs to a pure Python module in there that redirects to the real DLL.
The problem is most likely that the non-extension DLL that
vtkCommonPython.pyd links to is missing.

You will need to override the tno_can_auto_close method in a subclass 
and return True/False depending on what you want.  I think you could 
monkey patch this.  You typically won't need to get the node related to 
the dragged object -- see core/base.py for example.

When you call add_observer, it returns an index corresponding to the 
callback attached.  To remove the callback you can do something like so 
(untested):

  x = obj.add_observer('SomeEvent', cbk)
  obj.remove_observer(x)

Works on the mac.  You may want to avoid deleting the first scene you 
create.  That might be the source of the problem.  I also think this is 
cleaner:

  49    def _current_tab_default(self):
  50         return self.tabs_list[0]
  51
  52     def _tabs_list_default(self):
  53         return [DisplayTab()]

rather than what you had originally.

The statement is true when you are working on something that is 
available as open source not otherwise.

I don't know but thought that it should be endian-neutral but am not sure.

Excellent!  I just got everything built on my mac and it looks terrific. 
  Thanks for all the work on this!

Hmm, but the html.zip that is checked in is still at 13MB?

Yes. I can't check in the file: I get a timeout on the SVN. This is
really a pain, because it means I can't update the website either.

Peter, (or anybody else) any chance changing some settings on apache (eg
timeout) will improve the situation?

Cheers,

Gaël
