Class HVideoComponent

java.lang.Object

java.awt.Component

org.havi.ui.HComponent

org.havi.ui.HVideoComponent

All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, TestOpacity, HMatteLayer

public class HVideoComponent
extends HComponent

HVideoComponent is an opaque class encapsulating the presentation of a video source within an application, i.e. contained within a conventional AWT hierarchy.

An HVideoComponent obeys all conventional java.awt.Component semantics, including being clipped by its parent container, etc. An HVideoComponent also obeys all HComponent semantics including Z-ordering, etc.

The parameters to the constructors are as follows, in cases where parameters are not used, then the constructor should use the default values.

Default parameter values exposed in the constructors

Parameter	Description	Default value	Set method	Get method
None.

Default parameter values not exposed in the constructors

Description	Default value	Set method	Get method

Constructor Detail

HVideoComponent

protected HVideoComponent()

It is not intended that applications should directly construct HVideoComponent objects.

Creates an HVideoComponent object. See the class description for details of constructor parameters and default values.

Method Detail

getVideoDevice

public HVideoDevice getVideoDevice()

Returns the HVideoDevice that this HVideoComponent is associated with.

Returns:

the HVideoDevice that this HVideoComponent is associated with, or null if this cannot be determined.

addOnScreenLocationModifiedListener

public void addOnScreenLocationModifiedListener(HScreenLocationModifiedListener slml)

Register a listener to determine if the Component's on-screen location is modified - irrespective of its relative location to its parent Container. If the listener has already been added further calls will add further references to the listener, which will then receive multiple copies of a single event.

Parameters:

slml - listener to be notified when the on-screen location of the component is modified.

removeOnScreenLocationModifiedListener

public void removeOnScreenLocationModifiedListener(HScreenLocationModifiedListener slml)

Remove a listener that determines if the Component's on-screen location is modified - irrespective of its relative location to its parent Container. If the specified listener is not registered, the method has no effect. If multiple references to a single listener have been registered it should be noted that this method will only remove one reference per call.

Parameters:

slml - listener to be removed
