           Summary: qtruby can't discern overloaded function which have
                    QList parameter.
           Product: bindings
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kde-bindings at kde.org
        ReportedBy: ruby.twiddler at gmail.com


Version:           Rev: 1097205 Last Changed Date: 2010-03-01: ruby-1.8.7
(using KDE 4.4.0)
OS:                Linux
Installed from:    Compiled From Sources

qtruby can't discern overloaded function which have QList parameter.

KCoreConfigSkeleton::ItemEnum have two overloaded functions.
   ItemEnum (const QString &_group, const QString &_key, qint32 &reference,
const QList< Choice2 > &choices, qint32 defaultValue=0)

    ItemEnum (const QString &_group, const QString &_key, qint32 &reference,
const QList< Choice > &choices, qint32 defaultValue=0)

QList< Choise2 > and QList< Choise > are different.
but qtruby end with error.
/usr/lib/ruby/site_ruby/1.8/Qt/qtruby4.rb:2611:in `initialize': unresolved
constructor call KDE::ConfigSkeleton::ItemEnum (ArgumentError)


I want ruby to deal with it.
here is my patch to treat the problem.
