C++ / Python plugin, run native RV commands (RV 4.2.0)

RV 4.2.0

Custom python plugin based on rv.rvtypes.MinorMode, has custom c++ library with python interface.


I wat to run a few native RV commands in my plugin`s method:

def reload_session(self, event=None):
    if event:
    print 'Yo!'


Variant 1:

I`ve made RV main menu item in my python plugin init. Works great if I simply push that drop down main menu item.


Variant 2:

But menu item is not enough, my plugin has gui which generates in C++ library (works great), and I`ve created the button in my gui to run the same "reload_session" method.

Subvariant A:

I got PyObject* pointer to my plugin in my C++ library, and easily read attributes from plugin, like this: PyObject_GetAttrString(m_plug, "pid"). Works great so far.  But if I try to call method ( PyObject_CallMethod(m_plug, "reload_session", "()") ), SEGMENTATION FAULT error.  WHY???

Subvariant B:

In c++ I create the button, found "reload session" QAction* in QApplication*, and my button runs QAction`s trigger: qactReloadSession->trigger().  I see in the log how I call the trigger, but it does not start "reload_session" method of my plugin.  WHY???


Thank you

    Ok, I`ve found rvNetwork.py and that is good alternative.

    But if someone know the answer, will be very appreciate.

    Hi Evgeny,

    Sorry for the slow response! Are you currently up and running or is there something I can help with still? I am not sure I understand what you are trying to do. Can you please give me a high level walk through of your desired workflow?
