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.

Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
protected static final class	QtObject.QPrivateConstructor	This type is used as solo argument for internal constructors.

Constructor Summary

Constructors

Modifier	Constructor	Description
	QtObject()	Creates a new QtObject.
protected	QtObject(QtObject.QPrivateConstructor p)	Constructor for internal use only.

Method Summary

Modifier and Type	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.

Constructor Details

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.
