can't get connection tab to appear (No module named Qwt5)

[JR]

Hi, double-clicking on connection in the Session window doesn't make
the connection tab appear for me. I see the following error messages
in the console:

2008-12-04 00:10:05,009 DEBUG Exception (debug): ImportError('No
module named Qwt5',):No module named Qwt5 (h:<bound method Centra
lTabs.createTickerPlotTab of <profit.workbench.centraltabs.CentralTabs
object at 0x022068A0>>)
2008-12-04 00:10:05,026 DEBUG Exception (debug): ImportError('No

lTabs.createDisplayTab of <profit.workbench.centraltabs.CentralTabs
object at 0x022068A0>>)

I can make most of the other tabs appear by double-clicking on
executions, historical data, etc.

I am running this on Windows Vista with 2008-12-02 checkouts of IbPy
and ProfitPy. I am using Python 2.6. Any assistance would be much
appreciated.


Thanks,
JR

Do you have PyQwt 5 installed? If not, that's your first step. If
you do already have it, the issue is different, and not one that's
simply fixed (the pyqwt api is in flux). Please advise either way.

I just tried to install it...I'm having trouble doing this, but I'll
direct further questions regarding PyQwt installation to the PyQwt
mailing list.

In case you're curious as to where I'm stuck (feel free not to answer
- yes, this is a PyQwt issue rather than a ProfitPy issue) - it's
here:

$ make 4
cd configure \
&& python configure.py -4 -Q ../qwt-5.1 -j 1 \
&& make -j 1

My advice would be to read or re-read the README and INSTALL files.
If memory serves, the compilation and installation of PyQwt isn't
anything like your typical open source package. Best of luck,

I managed to install PyQwt by using the binary installer (you might
wonder why I didn't use the binary installer earlier - the reason is
that I had problems downloading it before, but the download is working
now). I no longer get the message "ImportError('No module named
Qwt5',):No module named Qwt5", however, I still can't get the
connection tab to appear. Here's what I see in the console now:

I am using Python 2.5.2 (I downgraded from 2.6 so that I could use the
PyQwt package built against Python 2.5), NumPy 1.2.1, PyQt-Py2.5-
gpl-4.4.3-1, and Windows Vista.

All of the code in profitpy is python, so any DLL error is coming from
a different extension module. Given that you get this while trying to
load a PyQwt component, the search starts there. A quick grep of the
trunk gives these imports:

./profit/workbench/widgets/ui_connectionwidget.py:from PyQt4.Qwt5
import QwtThermo
./profit/workbench/connectiondisplay.py:from PyQt4.Qwt5 import QwtThermo
./profit/lib/widgets/ui_plot.py:from PyQt4.Qwt5 import QwtPlot
./profit/lib/widgets/ui_plotitemdialog.py:from PyQt4.Qwt5 import QwtPlot
./profit/lib/widgets/plotitemdialog.py:from PyQt4.Qwt5 import QwtPlot,
QwtPlotCurve, QwtPlotMarker, QwtSymbol
./profit/lib/widgets/plot.py:from PyQt4.Qwt5 import QwtLegend,
QwtPicker, QwtPlot, QwtPlotCurve
./profit/lib/widgets/plot.py:from PyQt4.Qwt5 import QwtPlotGrid,
QwtPlotPicker, QwtPlotZoomer, QwtPainter
./profit/lib/widgets/plot.py:from PyQt4.Qwt5 import QwtPlotMarker,
QwtPlotPanner, QwtSymbol, QwtText

Fire up an interactive interpreter, and try each one of these imports
by hand. If you get a DLL error there, copy and paste it in a reply.
If you don't get a DLL error, well, we're in trouble.
