[PyQt] Overriding shouldInterruptJavaScript

[Brian Zambrano]

In my QWebPage, I'd like to override the shouldInterruptJavaScript method so
that it ignores long running javascript warning.

However, when I override it, it appears to never be called.

class DebugWebPage(QWebPage):

@pyqtSlot(bool)
def shouldInterruptJavaScript(self):
print 'not interrupting'
return False

It looks like someone else hit the same issue with PySide:

http://stackoverflow.com/questions/6868286/override-shouldinterruptjavascript-in-qwebpage-with-pyside

I'm tried with and without the pyqtSlot decorator with the same results.

Insight appreciated,
BZ

I don't think that Qt supports OS X Lion yet, you'll have to wait for 4.8 I 
guess.

Hard to say, what's going on. I guess, it cannot locate the ossim.so 
lib, at least not the version, that you linked to.

Maybe, it's just missing a call to ldconfig.

Try to check the python site libs with ldd, and compare with the build 
logs.

If that stuff is publically available somewhere, please provide a 
detailed description on what you did, which versions, etc., and I might 
try to reproduce your issue in a couple of days..
