Hello Phil,
Using sip-4.9.2-snapshot-20091108 here I've got a class with a public:
class WallpaperScript : Plasma::ScriptEngine {
// ...
public:
virtual void initWallpaper (const KConfigGroup& config);
// ...
}
When it is called from C++ I get a TypeError that 4 args were given
while only 2 were expected.
Digging into the cpp I found the method which cpp hits first:
-----------------------------------------------------------
void sipPlasma_WallpaperScript::initWallpaper(const KConfigGroup& a0)
{
sip_gilstate_t sipGILState;
PyObject *meth;
meth =
sipIsPyMethod(&sipGILState,&sipPyMethods[0],sipPySelf,NULL,sipName_initWallpaper);
if (!meth)
{
Plasma::WallpaperScript::initWallpaper(a0);
return;
}
typedef void (*sipVH_kdeui_64)(sip_gilstate_t,PyObject *,const
KConfigGroup&);
((sipVH_kdeui_64)(sipModuleAPI_plasma_kdeui->em_virthandlers[65]))(sipGILState,meth,a0);
}
-----------------------------------------------------------
When jumping through the table in the last line, it hits this code next:
-----------------------------------------------------------
bool sipVH_kdeui_64(sip_gilstate_t sipGILState,PyObject
*sipMethod,unsigned long a0,unsigned long a1,unsigned long
{
bool sipRes = 0;
PyObject *resObj = sipCallMethod(0,sipMethod,"mmm",a0,a1,a2);
if (!resObj || sipParseResult(0,sipMethod,resObj,"b",&sipRes) < 0)
PyErr_Print();
Py_XDECREF(resObj);
Py_DECREF(sipMethod);
SIP_RELEASE_GIL(sipGILState)
return sipRes;
}
-----------------------------------------------------------
As you can see it has the wrong parameters.
Oddly enough, the method below this one has the right parameters and it
probably the right one:
-----------------------------------------------------------
void sipVH_kdeui_65(sip_gilstate_t sipGILState,PyObject *sipMethod,const
KConfigGroup& a0)
{
PyObject *resObj =
sipCallMethod(0,sipMethod,"D",const_cast<KConfigGroup
*>(&a0),sipType_KConfigGroup,NULL);
if (!resObj || sipParseResult(0,sipMethod,resObj,"Z") < 0)
PyErr_Print();
Py_XDECREF(resObj);
Py_DECREF(sipMethod);
SIP_RELEASE_GIL(sipGILState)
}
-----------------------------------------------------------
I'm guessing that the jump table lookup is out by 1.
cheers,
