public abstract class QtObject extends QtJambiObject
The super class of all class types in Qt Jambi. Loading this class or any of its subclasses will imply a dependency on both the Qt Jambi library and the Qt libraries.

    Method
    Description
    final void
    dispose()
    Explicitly removes the native resources held by the object.
    boolean
    equals(Object other)
    Used to check if this object shares native resources with the other object if the other object is a subtype of QtJambiInterface.
    final boolean
    isDisposed()
    Is java object connected to native object?

    • QtObject

      public QtObject()
      Creates a new QtObject.

    • QtObject

      protected QtObject(QtObject.QPrivateConstructor p)
      Constructor for internal use only.
      Parameters:
      p - expected to be null.

  • Method Details

    • dispose

      public final void dispose()
      Explicitly removes the native resources held by the object. Note that though this method does not guarantee that the object will be garbage collected, it is not safe to reference the object after it has been disposed.

    • isDisposed

      @QtUninvokable public final boolean isDisposed()
      Is java object connected to native object?
      Returns:
      true if disposed

    • equals

      public boolean equals(Object other)
      Used to check if this object shares native resources with the other object if the other object is a subtype of QtJambiInterface. Otherwise it will return the result of calling the super class implementation.
      Overrides:
      equals in class Object
      Parameters:
      other - The object with which to compare
      Returns:
      true if the native resources of the two objects are one and the same.
