ANN: SpeedMeter Control For wxPython ;-)

andrea.gavana · September 26, 2005, 2:29pm

Hello Christian,

Yes, me. Not exactly the same but it seems to be a similar reason. I'm

using

python 2.3, wxpython 2.6.1.0 on linux:

Traceback (most recent call last):
  File "SpeedMeterDemo.py", line 890, in ?
    frame = SpeedMeterDemo()
  File "SpeedMeterDemo.py", line 390, in __init__
    self.SpeedWindow6.SetMiddleIcon(icon)
  File "/home/ck/testarea/SpeedMeter/SpeedMeter.py", line 1322, in
SetMiddleIcon raise "\nERROR: Invalid Icon Passed To SpeedMeter."

ERROR: Invalid Icon Passed To SpeedMeter.

This comes from the fact that I has some icons called ".ICO" and others
".ico". On Windows, there is no difference between these files, while on
Unix/Linux they are different. So, probably, renaming all the ".ICO" files
to ".ico" files will do the job. I attach a revised version of SpeedMeter
with all the files with ".ico" extension.

Sorry for this, I am clearly not an expert on Unix/Linux.

Thanks to have tried the demo and please, NG, let me know your
comments/suggestions.

Andrea.

The uppercase letters were the first thing that I thought could be the problem - unfortunately they are not. Any other ideas?

I take everything back!
Silly me overlooked that not only the extensions were uppercase! Thanks.
However the control in the lower left corner is not working and there's a bunch of error messages concerning some unicode issues. I'll attach the output.

This first one is because the "º" symbol. around line 259 in

to

This one is because the pi symbol.
A simple hack to avoid this one is to change around line 365 in
SpeedMeterDemo.py this:
ticks = ["0", "<pi/>/6", "sq(<pi/>)", "2<pi/>/3", "<pi/><sup>2</sup>/4",
"<pi/>", "7<pi/>/6", "4<pi/>/3"]

to this:

ticks = ["0", "pi/6", "sq(pi)", "2pi/3", "pi<sup>2</sup>/4", "pi",
"7pi/6", "4pi/3"]

I Andrea,
you can forget those changes I suggest and do this one instead.
If you put this line in the beginning of SpeedMeterDemo.py it works on linux.
Try on Windows but I suppose it will work too.

wx.SetDefaultPyEncoding('iso8859-1')

Hello NG,

I went back from holydays yesterday (what a great country is Canada
), and I read your messages about SpeedMeter. Thanks to everyone that
has tried the demo and the control, I really appreciate your comments.
Regarding the last mail from Ricardo Pedroso:
