EzTemplate object has no close function

[durack1]

The EzTemplate object has no close or exit functions, so I am uncertain how to purge or manipulate an EzTemplate object during an interactive session once it is created (and previewed):

>>> Canvas = EzTemplate.Multi(rows=2,columns=2)
>>> Canvas.preview('Template4x4',bg=bg)
>>> dir(Canvas)
['__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__slots__', '__str__', '__subclasshook__', '_columns', '_getcolumns', '_getrows', '_gettemplate', '_rows', '_setcolumns', '_setrows', '_settemplate', '_template', 'clean', 'columns', 'get', 'id', 'legend', 'list', 'margins', 'preview', 'rows', 'spacing', 'template', 'template_names', 'x']
>>> Canvas.clean()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/uvcdat/2.4.0rc1/lib/python2.7/site-packages/vcsaddons/Multi.py", line 229, in clean
    self.x.removeP(t)
  File "/usr/local/uvcdat/2.4.0rc1/lib/python2.7/site-packages/vcs/Canvas.py", line 1275, in removeP
    return self.canvas.removeP(*args)
AttributeError: 'module' object has no attribute 'removeP'

During the session above, a VCS canvas window appears, however I am unable to close this using the X (top right corner) or using a Canvas.close() (or equivalent, that I can find) on the commandline.

it shouldn't. When you do a get you get a template that you can remove. Will fix the clean issue.
By the way you do NOT get a canvas back. it's an EZTemplate object, not a vas canvas.

@doutriaux1 ok, so I have a persistent Canvas/EzTemplate object that I cannot close.. So how do I go about closing it using a get?

The inability to close this window using the X in the top right hand corner is a nasty bug.. The only way that I can kill this persistent window is to terminate my active python session, which is not reasonable for what should be a very simple (and intuitive) operation.

[doutriaux1]

you mean after a preview?

[durack1]

@doutriaux1 exactly..

[doutriaux1]

yes after the preview it is a canvas, you can access it as Canvas.x.close() in your case. You're right Canvas.preview() should probably return an handle to the canvas.

[doutriaux1]

will put this in the bug fix. Will become something like that:

Multi = EzTemplate.Multi(rows=2,columns=2)
Canvas = Multi.preview('Template4x4',bg=bg)
Canvas.close()

[durack1]

@doutriaux1 ok so Canvas.x.close() works (the window terminates), but I had no idea that I needed to call the x to initiate a close.. The above looks much more reasonable to me..

[durack1]

@doutriaux1 also, the inability to close it using the window/canvas controls (top right hand X) is also a concern to me.. These window controls should always work..

[durack1]

@doutriaux1 fixed #1591?

[doutriaux1]

yes
