Method Detail

addComponent

void addComponent(Component c)

Adds the component into this container.

Parameters:

c - the component to be added.

removeComponent

void removeComponent(Component c)

Removes the component from this container.

Parameters:

c - the component to be removed.

removeAllComponents

void removeAllComponents()

Removes all components from this container.

replaceComponent

void replaceComponent(Component oldComponent,
                      Component newComponent)

Replaces the component in the container with another one without changing position.

This method replaces component with another one is such way that the new component overtakes the position of the old component. If the old component is not in the container, the new component is added to the container. If the both component are already in the container, their positions are swapped. Component attach and detach events should be taken care as with add and remove.

Parameters:

oldComponent - the old component that will be replaced.

newComponent - the new component to be replaced.

getComponentCount

int getComponentCount()

Gets the number of children this ComponentContainer has. This must be symmetric with what HasComponents.getComponentIterator() returns.

Returns:

The number of child components this container has.

Since:

7.0.0

moveComponentsFrom

void moveComponentsFrom(ComponentContainer source)

Moves all components from an another container into this container. The components are removed from source.

Parameters:

source - the container which contains the components that are to be moved to this container.

addComponentAttachListener

void addComponentAttachListener(ComponentContainer.ComponentAttachListener listener)

Listens the component attach events.

Parameters:

listener - the listener to add.

addListener

@Deprecated
void addListener(ComponentContainer.ComponentAttachListener listener)

Deprecated. Since 7.0, replaced by addComponentAttachListener(ComponentAttachListener)

removeComponentAttachListener

void removeComponentAttachListener(ComponentContainer.ComponentAttachListener listener)

Stops the listening component attach events.

Parameters:

listener - the listener to removed.

removeListener

@Deprecated
void removeListener(ComponentContainer.ComponentAttachListener listener)

Deprecated. Since 7.0, replaced by removeComponentAttachListener(ComponentAttachListener)

addComponentDetachListener

void addComponentDetachListener(ComponentContainer.ComponentDetachListener listener)

Listens the component detach events.

addListener

@Deprecated
void addListener(ComponentContainer.ComponentDetachListener listener)

Deprecated. Since 7.0, replaced by addComponentDetachListener(ComponentDetachListener)

removeComponentDetachListener

void removeComponentDetachListener(ComponentContainer.ComponentDetachListener listener)

Stops the listening component detach events.

removeListener

@Deprecated
void removeListener(ComponentContainer.ComponentDetachListener listener)

Deprecated. Since 7.0, replaced by removeComponentDetachListener(ComponentDetachListener)
