[PyQt] Playing an ogg file with QtMultimedia?

Did you try to play the same .ogg file with another (external) player?
I did play multimedia files on Linux with QtMultimedia succesfully but I have to check and see if it was .ogg (I believe I did). I also used the fromLocalFile option for that to be sure. I'm not sure but I think that I read that spaces inside the path to the codecs can cause problems.
Best regards,Rembrand

Hello Group members
If I have an com / active-x based camera viewer library (in order to create
a viewing pane in my pyqt based application) can I use qaxcontainer for
that?
What are the pitfalls and things to be careful with?
Are there limitations?
Best regards
Carl.

Hello All,
I am trying to obtain a list (indices) of selected cells in a QTableView
using this script (in 3D slicer interface):
table = qt.QTableView()
...
#setup of the table and adding models and items etc.
...
select = table.selectionModel()
index = select.selectedIndexes()
and I get this error:
File "<console>", line 1, in <module>
ValueError: Called QList<QModelIndex> selectedRows(), return type
'QList<QModelIndex>' is ignored because it is unknown to PythonQt. Probably
you should register it using qRegisterMetaType() or add a default
constructor decorator to the class.
Any hint on which way is better and how can I register an unknown type in
PythonQt?
Best,
Saeed

PythonQt != PyQt ;)
