A set_trace() that works with PyQt4

Project description

Set a tracepoint in the Python debugger that works with PyQt4

It uses ipdb if is available


From PyPI:

$ pip install pdb4qt

Or by downloading the source and running:

$ python install

Or, for the latest git version:

$ pip install git+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
