How to raise OgreException - Ogre Addon Forums

Forgive me if this is a stupid question, but what kind of object is typically passed into the OgreException class constructor? From looking at the class definition in _ogre_exceptions_.py it looks like an object that has the getFullDescription method (from looking at the __str__ method), but this class bears little similarity to the C++ OgreException class

The reason I ask is that I want to raise an OgreFileNotFoundException if a given file cannot be located, but I want to do it correctly so that try-except blocks can handle it just like other OgreExceptions.

Thanks in advance!

I'm very new to ogre and python-ogre (maybe somebody else has a better solution

), however something like the code I wrote up below may be what you're looking for. Not sure about the value for "errorCode", however this should be enough for you to build on:



#!/usr/bin/env python



import ogre.renderer.OGRE as ogre

import ogre.renderer.OGRE._ogre_ as ogreInternal

import ogre.io.OIS as OIS

import array

import code

import sys

import os

import inspect



def lineno():

    """Returns the current line number in our program."""

    return inspect.currentframe().f_back.f_lineno



class ExceptionThrower(object):

    def __init__(self):

        filename = os.path.basename(sys.argv[0])

        errorDesc = "Description of error"

        errorCode = 3

        exInfo = ogreInternal._FileNotFoundException_(int(errorCode), errorDesc, self.__class__.__name__, filename, long(lineno()))

        raise ogre.OgreFileNotFoundException(exInfo)



if __name__ == '__main__':

    try:

        ExceptionThrower()

        

    except ogre.OgreException, e:

        print e
