Constructor Detail

IlvAbstractStaticViewContainer

public IlvAbstractStaticViewContainer()

Constructs a new IlvAbstractStaticViewContainer instance.

IlvAbstractStaticViewContainer

public IlvAbstractStaticViewContainer(IlvDocumentView view)

Constructs a new IlvAbstractStaticViewContainer instance that contains the specified document view. The method getViews() returns an array of one element containing this document view and the findViews() is not called.

Parameters:

view - The document view owned by this view container.

Method Detail

getViews

public IlvDocumentView[] getViews()

Returns the document views of this container that are provided with the findViews() method.

Specified by:

getViews in interface IlvViewContainer

Returns:

the array of views of this view container.

findViews

protected abstract IlvDocumentView[] findViews()

Invoked by the getViews() method to retrieve the document views contained by this view container. This method is invoked only the first time the getViews() is invoked. The views returned by this method are then stored and returned the next time the getViews() method is called.

Returns:

the array of views of this view container.

activate

public abstract void activate()

Sets the container as active.

Specified by:

activate in interface IlvViewContainer

isContainerVisible

public boolean isContainerVisible()

Determines whether this view container is visible. The default implementation of this method returns false.

Specified by:

isContainerVisible in interface IlvViewContainer

Returns:

true if the container is visible; false otherwise.

See Also:

setContainerVisible(boolean)

setContainerVisible

public void setContainerVisible(boolean visible)

Shows or hides this view container depending on the value of the visible parameter. The default implementation of this method is empty.

Specified by:

setContainerVisible in interface IlvViewContainer

Parameters:

visible - If true the view container is shown; if false the view container is hidden.

See Also:

isContainerVisible()

updateAction

public boolean updateAction(Action action)

Invoked by the application to update the state of the specified action.
By default, this method invokes the list of action handlers added to the view container with the method addActionHandler(ilog.views.appframe.event.ActionHandler) until one action handler can update the action.

Specified by:

updateAction in interface ActionHandler

Parameters:

action - The action to update.

Returns:

true if one action handler can update the specified action; false otherwise.

See Also:

addActionHandler(ilog.views.appframe.event.ActionHandler)

isProcessingAction

public boolean isProcessingAction(String command)

Determines whether the view container can perform the action with the specified command key in its actionPerformed(java.awt.event.ActionEvent) method. By default, this method returns true if one action handler added to the view container can process this action; false otherwise.

Specified by:

isProcessingAction in interface ActionHandler

Parameters:

command - The command key of the action.

Returns:

true if the action listener performs the specified action; false otherwise.

See Also:

addActionHandler(ilog.views.appframe.event.ActionHandler), actionPerformed(java.awt.event.ActionEvent)

actionPerformed

public void actionPerformed(ActionEvent e)

Invoked when an action occurs. If an action handler added to the view container can process this action, its ActionListener.actionPerformed(java.awt.event.ActionEvent) method is invoked; otherwise this method does nothing.

Specified by:

actionPerformed in interface ActionListener

See Also:

addActionHandler(ilog.views.appframe.event.ActionHandler)

addActionHandler

public void addActionHandler(ActionHandler actionHandler)

Adds the specified actionHandler to the list of action handlers of the view container.

Parameters:

actionHandler - The new action handler to add.

See Also:

removeActionHandler(ilog.views.appframe.event.ActionHandler)

removeActionHandler

public boolean removeActionHandler(ActionHandler actionHandler)

Removes the specified actionHandler from the list of action handlers managed by this view container.

Returns:

true if the action handler was previously added; false otherwise.

See Also:

addActionHandler(ilog.views.appframe.event.ActionHandler)

getProperty

public Object getProperty(String key)

Returns the property of this view container with the specified key.

Specified by:

getProperty in interface IlvPropertyManager

Parameters:

key - The non-null property key.

Returns:

The value of the specified property. It returns null if the specified property was not found.

See Also:

setProperty(java.lang.String, java.lang.Object)

setProperty

public Object setProperty(String key,
                          Object value)

Changes the value of one of the properties of this view container. If the value has changed, a PropertyChangeEvent is sent to the property change listeners.

Specified by:

setProperty in interface IlvPropertyManager

Parameters:

key - The non-null property key.

value - An Object value. If it is equal to null, the property with the specified key is removed.

Returns:

The previous value of the property.
