UnicodeDecodeError
hi, one of the modules in my programs stopped wroking after i upgraded from python 2.3 to 2.4. I also changed my wxPython to unicode supported one during the process. what the module essentially does is search for a stirng pattern form a list of strings. this is the function: def srchqu(self): for i in range(1,len(qu)):#qu is the list of strings if qu[i][0].lower().find(self.query)==-1: pass else: #do some stuff here I get this error message on calling the function: Traceback (most recent call last): File "E:\mdi\search.py", line 86, in OnSrchButton self.srchqu() File "E:\mdi\search.py", line 97, in srchqu if qu[i][0].lower().find(self.query)==-1: UnicodeDecodeError: 'ascii' codec can't decode byte 0x92 in position 66: ordinal not in range(128) what is the problem and the solution? thanks in advance for any help. Ashoka -- http://mail.python.org/mailman/listinfo/python-list
Re: UnicodeDecodeError
Thanks Fredrik, i decoded both qu[i][0] and self.query to latin_1
(self.query.decode("latin_1")) and i am not getting the error now.
If you dont mind, I have another question for you. I use wxPython for
GUI development. When i use a string containing "&" character as a
label for statictext, the "&" does'nt appear.It is replaced by a short
_. I have tried different encodings but have no success. what should i
do so that "&" appears on screen?
thanks once againg for your help.
regards,

register keyevent in wxpython
hi, is there a way to register application wide hotkey in wxpython? i tried wxWindow::RegisterHotKey(). but the problem is it registers the hotkey as a system wide hotkey. this causes problems in other applications running concurrently which use the same hotkey. i want to do this because i want my app frame (a mdi frame) to accept the key event and wx.frame accepts only wx.eventCharHook() which raises no keyevent for normal alphanumeric keys. any ideas?? thanks in advance for any help. -- http://mail.python.org/mailman/listinfo/python-list
Enthought python - Traits
Hello everyone !
I am trying to find some sort of a cookbook or more examples for using
Enthought Traits to build GUI's. I tried to follow the documentations
present at the enthought site, but couldnt get too far - especially on
how to handle a control event ?
Also while i am on the topic:
say i have a list "control" that create using the following two lines:
class Project(HasTraits):
coordinate_system=Enum('Cartesian','Cylindrical')
I added the following line to get the option selected by the user:
def _coordinate_system_changed(self,old,new):
print 'System changed from %s to %s ' %(old,new)
but it does not return what the user select. It should return either 0
or 1 based on the two choices, but i can't seem to find a way to trap
that.
I am relatively new to this GUI programming in Python and really could
use some tips/hints.
Thanks,
-Ash

Re: Enthought python - Traits
Thanks Peter .. I will check out the mailing list. In the meanwhile - i
have made some progress. Now working out - how to get a button_fired
event to actually return the values ..
It's a process (as always..)

What if I want to output only the specific logger to console and
ignore every other?

Tkinter, IDLE keeps crashing
Hey, So I've actually had this problem for awhile, and I cant seem to get anything to work. I've followed all the steps & procedures that my google searches have provide me, but I can't seem to get the Tkinter module or the Python IDLE IDE to work. For instance, if I click IDLE on my mac, it'll open up for a quick sec & produce an error. Or if I go into the Python interpreter, I import Tkinter, call Tk() Then it says: CGColor 1 components Abort Trap: 6, then get an error. I'll post this crash report below. My system is a Mac OS X 10.7 Lion. I'm running 2.7.3 Python I've installed the recommended version of ActiveState TCL/TK I still have problems. Does anyone have this problem, or know how to fix it?

I assume you are complaining about the fact that it's not printing exactly 40.4, and wondering where the error is coming from. (It helps if you actually state this yourself, so we don't have to assume it, rather than just laying out the circumstances.) The answer is that floating point numbers are inherently imprecise.
