[PyQt] SIP template-based class with argument having default constructor as default value

[Denis Rouzaud]

Hi all,

Title says it all ;)

I think there is an issue on how SIP handles the default value argument for
template-based classes.
SIP don't replaces the T var by the implemented  base class constructor.
See below.

Let's say I have

template <typename T>
class Base
{
  pubic:
    Base( const T &epoch = T()) : mEpoch( epoch ){}
  private:
    T mEpoch;
}

typedef Base< QDate > MyDate;
typedef Base< QDateTime > MyDateTime;


Here is the SIP code generated:

static void *init_type_MyDate(sipSimpleWrapper *, PyObject *sipArgs,
PyObject *sipKwds, PyObject **sipUnused, PyObject **, PyObject
**sipParseErr)
{
    MyDate *sipCpp = 0;
    {
        const QDate& a0def = T();
        const QDate* a0 = &a0def;
        int a0State = 0;
......


I get an error:
use of undeclared identifier 'T'
     in   const QDate& a0def = T();


Does someone confirm?
Is there a workaround?
Cheers,
Denis
