Unable to use the operator== of QValueList

[wysota]

As follow

bool CClassA::operator==(const CClassA& aca)
{
	if( m_dAMember == aca.m_dAMember )
		return true;
	else
		return false;
}

bool CClassA::operator==(const CClassA& aca)
{
	if( m_dAMember == aca.m_dAMember )
		return true;
	else
		return false;
}

To copy to clipboard, switch view to plain text mode 

Make it:

bool CClassA::operator==(const CClassA& aca) const
{
	 return ( m_dAMember == aca.m_dAMember );
}

bool CClassA::operator==(const CClassA& aca) const
{
	 return ( m_dAMember == aca.m_dAMember );
}

To copy to clipboard, switch view to plain text mode 

Note the "const" at the end of function header.
