I'm moving some Qt4.8.2 code which uses QWeakPointer to Qt5.6. Simplifying a
lot it looks like this:
class MySettings : public QObject
{
Q_OBJECT
}
class MyClass : public QObject
{
Q_OBJECT
private:
QWeakPointer<MySettings> m_xSettings;
}
MyClass::MyClass(MySettings* pSettings, QObject* pParent)
: QObject(pParent)
, m_xSettings(pSettings)
{
}
but when I compile under Visual Studio 2013 I get this error:
error C2664: 'QWeakPointer<MyClass>::QWeakPointer(const QSharedPointer<T> &)' : cannot
convert argument 1 from 'MySettings *' to 'const QWeakPointer<MySettings> &'
I tried changing the QWeakPointer to a QPointer but now I'm getting:
error C2440: 'static_cast' : cannot convert from 'QObject *' to MyClass *'
(GeneratedFiles\Debug\moc_MyCode.cpp)
Is there a recommended method for migrating the use of QWeakPointer into Qt5?
With this code, you need QPointer.
