[PyQt] Catching exceptions everywhere

[Lukas Hetzenecker]

Hello,

you could redirect the interpreter’s standard error output stream:
sys.stderr = YourClass(window.edit,  sys.__stderr__,  QColor(Qt.red))
YourClass in an "file-like" object (it has an write function)
window.edit is an instance of Qt's QTextEdit class and is used to display the 
message.

Here is an example: http://series60-remote.svn.sf.net/viewvc/series60-
remote/trunk/pc/series60-remote.py?view=markup ,  line 288

The class QtOutput is defined here: http://series60-
remote.svn.sf.net/viewvc/series60-
remote/trunk/pc/lib/log.py?revision=257&view=markup , line 36

And the window that actually displays an error message is here: 
http://series60-remote.svn.sf.net/viewvc/series60-
remote/trunk/pc/window/log.py?view=markup

A screenshot is here:

The Traceback is colored red in the window.

Starting with this is should be easy to get a "report bug"-dialog ;-)

If you have any questions please just ask.

Greetings,
Lukas
