<![CDATA[error: ‘QVariant::QVariant(void*)’ is private inline QVariant(void *) Q_DECL_EQ_DELETE;]]>Hi all

I am trying to use C++ class in qml using setcontext property method, but when i try to build it it is giving the following error

/opt/Qt5.8.0/5.8/gcc_64/include/QtCore/qvariant.h:471: error: ‘QVariant::QVariant(void*)’ is private
inline QVariant(void *) Q_DECL_EQ_DELETE;

what may be the issue for this? what changes i need to make ?

thanks

You'll have to use QVariant::fromValue() to avoid implicit cast to bool and end up using QVariant(bool).

T *ptr = ...;
QVariant v1 = ptr; // not ok
QVariant v2 = QVariant::fromValue(ptr); // ok
