[PyQt] Catching exceptions everywhere

[Lukas Hetzenecker]

Hello,

this is also done in my example.
sys.__stderr__ stores the original value of the error output handler.
If a new message is shown it is also written to this object:

Main class:
sys.stderr = lib.log.QtOutput(self.logWindow.outputEdit,  sys.__stderr__,  
QColor(Qt.red))

QtOutput class:
def __init__(self, parent, out=None, color=None):
   # ... out is sys.__stderr__
def write(self, m):
   # Write message to TextEdit
   self.textWidget.insertPlainText( m )

   # Write message to original sterr
   self.out.write(m)
