I have this line of code:
self.emit( PYSIGNAL("signalNewViewerImage"), (QPixmap(filename),) )
It's possible for the filename, and hence the pixmap, to be None. The slot
handles this eventuality. However, when I run the code under these
circumstances, I get:
File "./view/PublishImageView.py", line 47, in slotShowImage
(self.queryCurrentFilename(),) )
File "./model/PublishImageModel.py", line 33, in slotGenerateImage
self.emit( PYSIGNAL("signalNewViewerImage"), (QPixmap(filename),) )
File "/usr/lib/python2.2/site-packages/qt.py", line 43, in __init__
libqtc.sipCallCtor(222,self,args)
RuntimeError: Cannot pass None as argument 0 in this call
which seems self explanatory, although a bit odd. Is it not possible to pass
None as a parameter through the signal emitting system, or have I done
something wrong?
