I'm having two problems with the QtAgg backend. If I do:
from pylab import *
plot([1,2])
[<matplotlib.lines.Line2D instance at 0x2aaab1ead830>]
show()
My figure window should be 8in x 6in, but instead it is 6in tall and as wide
as my screen will allow. So thats the first issue. The second is this: if I
close that window, and then do
plot([1,2])
[<matplotlib.lines.Line2D instance at 0x2aaab1ebbcf8>]
show()
I get the following traceback:
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib64/python2.4/site-packages/matplotlib/backends/backend_qt.py",
line 47, in show
manager.window.show()
RuntimeError: underlying C/C++ object has been deleted
I'm using qt version 3.3.4, with cvs mpl 0.86.2, on a gentoo linux system. The
only nondefault rc setting is the choice of backend.

Respectfully: Is the QtAgg backend supported?

Darren,
I'll have someone take a look at it soon. We're right in the middle of a big delivery so we don't really have a lot of time to spend on this right now...

Darren,
I'll have someone take a look at it soon. We're right in the middle of a
big delivery so we don't really have a lot of time to spend on this right
now...
Thanks, Ted. I'm not in a rush.
I'm about to start my first python-based gui project, and want to use Qt. I'll
also continue to poke around at these problems myself as I find time.

Hmm - I just ran your test and everything seems to work fine. I'm using MPL 0.85 and Qt 3.3.5. I did a diff of backend_qt.py and backend_qtagg.py from 0.85 to the current CVS repository and they're identical. So I'm not sure what could be going on...

Hmm - I just ran your test and everything seems to work fine. I'm using
MPL 0.85 and Qt 3.3.5. I did a diff of backend_qt.py and backend_qtagg.py
from 0.85 to the current CVS repository and they're identical. So I'm not
sure what could be going on...
Maybe this is not an issue with qt-3.3.5.
Another datapoint: when I run the embedding_in_qt.py example, the size of the
window is correct.
