Avoiding wxPython PrintPreview segmentation fault or double free error

Posted 11-28-2008 at 08:23 PM by dr_agon

applies to: Python, wxPython (v.2.8), wxWidgets, wx.PrintPreview, wx.Printout

When creating wx.PrintPreview class, you must pass 2 parameters of wxPrintout class (see doc)
If someone (like me) gets a silly idea of passing the same instance of wxPrintout class as both parameters, on closing the preview frame he will get segmentation fault or double free error.
Example (don't do this!):

Code:

class MyPrintout(wx.Printout):

mepis 7

Posted 11-28-2008 at 07:36 PM by olderone

I have recently used the liveCD for Mepis 7 & found that I can play mp3's, jpg & even movie shots taken from my camera, copying from a CF card on the USB. I am very new to Linux & I would like to be able to connect to the internet wirelessly as I do with XP. So far no go. I have a Speedtouch 121g wireless adapter plugged into a USB socket. Can anyone tell me how I can do this, or is it not possible without having to install it on the hard drive. The router is WEP encrypted.

No matter what distro you use, I think we can all agree that Roy Orbison is the coolest guy who ever lived. With the 20th anniversary of his untimely death coming up next Saturday (6th of December), I implore you to go out and buy a Roy Orbison CD and celebrate his life.

Anyway, once you've done that, get back to work.

Happy Thanksgiving!

Posted 11-27-2008 at 02:36 PM by linuxpokernut

Yes Happy Thanksgiving, even to M$ users. I just had one thought before going to Turkey dinner at my Moms:

How many people said/will say they are thankful for open source at the dinner blessings tonite?

Does that seem weird to you? I dont know what to make of it. Sounds a bit 'nerdy' to be talking about at the dinner table, but if you think about it it makes sense. People donating time and effort to create free software and more people donating more time to teach new...
