Class QGenericArgument

java.lang.Object
io.qt.core.QGenericArgument
public final class QGenericArgument extends Object

Specifies a function pointer's argument type and value.

Qt's object types are represented by pointers, value types by values, e.g.:

Java class QWidget leads to QWidget* function return type, Java class QColor leads to QColor function return type (as value).

Use asRef() to call values and objects by reference type (e.g. QColor&, QObject&).

Use asConstRef() to call values and objects by const reference (e.g. const QColor&).

Use asPointer() to call values by pointers (e.g. QColor*).
