A set_trace() that works with PyQt4
Set a tracepoint in the Python debugger that works with PyQt4
It uses ipdb if is available
$ pip install pdb4qt
Or by downloading the source and running:
$ python setup.py install
Or, for the latest git version:
$ pip install git+git://github.com/nqnwebs/pdb4qt.git
Simply import set_trace from pdb4qt and call it where you want to do the breakpoint:
from pdb4qt import set_trace; set_trace()
Why it’s needed?
Standard pdb/ipdb set_trace returns a loop of QCoreApplication::exec: The event loop is already running that disallow to input anything.
It’s heavily inspired on the answer of the user quark from this stackoverflow’s thread
