Class QGenericReturnType<T>

java.lang.Object

io.qt.core.QGenericReturnType<T>

Type Parameters:

T -

public final class QGenericReturnType<T>
extends Object

Specifies a function pointer's return type.

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 return values and objects as reference type (e.g. QColor&, QObject&).

Use asConstRef() to return values and objects as const reference (e.g. const QColor&).

Use asPointer() to return values as pointers (e.g. QColor*).
