Constructor and Description
VideoContainer(Component noVideoComponent, boolean conference) Initializes a new VideoContainer with a specific Component to be displayed when no remote video is available.

Method Summary

Modifier and Type	Method and Description
Component	add(Component comp) Adds the given component at the VideoLayout.CENTER_REMOTE position in the default video layout.
Component	add(Component comp, int index)
void	add(Component comp, Object constraints)
void	add(Component comp, Object constraints, int index) Overrides the default behavior of add in order to be sure to remove the default "no video" component when a remote video component is added.

Field Detail

DEFAULT_BACKGROUND_COLOR

public static final Color DEFAULT_BACKGROUND_COLOR

The default background color of VideoContainer when it contains Component instances other than noVideoComponent.

Constructor Detail

VideoContainer

public VideoContainer(Component noVideoComponent,
                      boolean conference)

Initializes a new VideoContainer with a specific Component to be displayed when no remote video is available.

Parameters:

noVideoComponent - the component to be displayed when no remote video is available

conference - true to dedicate the new instance to a telephony conferencing user interface; otherwise, false

Method Detail

add

public Component add(Component comp)

Adds the given component at the VideoLayout.CENTER_REMOTE position in the default video layout.

Overrides:

add in class Container

Parameters:

comp - the component to add

Returns:

the added component

add

public Component add(Component comp,
                     int index)

Overrides:

add in class Container

add

public void add(Component comp,
                Object constraints)

Overrides:

add in class Container

add

public void add(Component comp,
                Object constraints,
                int index)

Overrides the default behavior of add in order to be sure to remove the default "no video" component when a remote video component is added.

Overrides:

add in class Container

Parameters:

comp - the component to add

constraints -

index -

remove

public void remove(Component comp)

Overrides the default remove behavior in order to add the default no video component when the remote video is removed.

Overrides:

remove in class Container

Parameters:

comp - the component to remove

removeAll

public void removeAll()

Ensures noVideoComponent is displayed even when the clients of the videoContainer invoke its #removeAll() to remove their previous visual Components representing video. Just adding noVideoComponent upon ContainerEvent#COMPONENT_REMOVED when there is no other Component left in the Container will cause an infinite loop because Container#removeAll() will detect that a new Component has been added while dispatching the event and will then try to remove the new Component.

Overrides:

removeAll in class Container
