Font error leading to a timer error?

Gadget_Steve · May 27, 2013, 7:23am

Hi,
I think that you need to out-dent your return statement - otherwise
if the if statement is true you return Nothing if false then you
return a font family.
This might have some bearing.

  I was running into a font error earlier in which was being shown
in_gdi.py (failure point)
  In customtreectrl.py, **family** had a value 74. I saw some
threads where it said that it was a wx.Font bug and that it should
return FONTFAMILY_DEFAULT instead… which is why i added the else
condition below…
   if family == wx.FONTFAMILY_UNKNOWN:

              print "inside family condition"

              family = wx.FONTFAMILY_SWISS

          else:  #Else condition added by KB

              print "inside else family condition"

              family = wx.FONTFAMILY_DEFAULT  #KB

              return family



  After adding the else condition in customtreectrl.py in
wx/lib/agw, the font error does not come up but another error
  typeerror in method new_Timer expected argument of type
wxEvtHandler. (failure point is _misc.py) . I dont know if I am
landing on the right error after resolving the previous one or is
it just random?
  If you feel I have landed on error 2 validly from error 1, that i
had… pls let me know if i m on the right track.
  Any suggestions?

return

should be

return

As it stands, I don’t see how it can return anything. (Maybe I’m missing something?)

I think you have larger indentation issues than that, actually - it’s hard to know whether the issue is in your code, or whether it’s an email formatting problem, but I think that your structure

if:

    stuff

else:

Hi Marc:

It is really the indentation in the email. Additionally, I accidentally was returning something… the return should not be present there at all as the code has to proceed.

My issue is that “family” has a value 74 and wx.FONTFAMILY_UNKNOWN has value 77.

I added the else condition in this wx/lib/agw/customtreectrl.py file, based on https://groups.google.com/forum/?fromgroups#!topic/wxPython-dev/9al_nta49no thread number 17.

print “family is”, family
print “wx.FONTFAMILY_UNKNOWN is”, wx.FONTFAMILY_UNKNOWN
if family == wx.FONTFAMILY_UNKNOWN:
print “inside if condition”
family = wx.FONTFAMILY_SWISS
else: #Else condition added by KB
print “inside else condition”
family = wx.FONTFAMILY_DEFAULT
val = self._normalFont.GetPointSize()
print “val is”, val
self._boldFont = wx.Font(self._normalFont.GetPointSize(), family,
self._normalFont.GetStyle(), wx.BOLD, self._normalFont.GetUnderlined(),
self._normalFont.GetFaceName(), self._normalFont.GetEncoding())
self._italicFont = wx.Font(self._normalFont.GetPointSize(), family,
wx.FONTSTYLE_ITALIC, wx.NORMAL, self._normalFont.GetUnderlined(),
self._normalFont.GetFaceName(), self._normalFont.GetEncoding())

    # Hyperlinks things
    self._hypertextfont = wx.Font(self._normalFont.GetPointSize(), family,
                                  self._normalFont.GetStyle(), wx.NORMAL, True,
                                  self._normalFont.GetFaceName(), self._normalFont.GetEncoding())
    self._hypertextnewcolour = wx.BLUE
    self._hypertextvisitedcolour = wx.Colour(200, 47, 200)

I run into "Exception – PyAssertionError:C++ assertion “Ok()” failed at …..\src\msw\font.cpp (1024) in wxFont::GetPointSize():invalid font.

Would someone please be able to tell me where i could find font.cpp? I cant find it in my local folders!

Any suggestions will be appreciated to get me on the right track!

Could you re-post this, either with formatting turned off or in a
monospaced font? The indentation and line wrapping are so messed up that I
for one can't make any sense of it as it stands.

Which call to GetPointSize() is failing? I see you're putting in print
statements to help you trace your progress (excellent!) - so where are you
when things go wrong? In other words, what's the last thing that prints
before the error?

I don't think your error will end up being in font.cpp; it will be that you
don't actually have a valid font object when you make the call.

font.cpp is C++, I doubt that the problem is in there.
Look at the exception and “go up” the traceback until you see a line
in your code and check that line with e.g. a debugger and make sure
that you have a valid font.
e.g. is “self._normalFont” always a valid font when you use it?

Have you tried using the latest version of the AGW code? You can get it from SVN at http://svn.wxwidgets.org/svn/wx/wxPython/3rdParty/AGW/.

If that doesn't help then please make a runnable, small as possible, sample application that demonstrates the problem. MakingSampleApps - wxPyWiki
