addPanel

void addPanel(IPanel panel)
              throws BaseException

Adds another IPanel to this group.

Parameters:

panel - the IPanel to add

Throws:

EmptyPanelGroupException - if there was no panel loaded and tries to add a new one, launches this exception if the panel to add hasn't been registered to this component and then, no remains without panels

EmptyPanelGroupGUIException - if there was no panel loaded and tries to add a new one, launches this exception if the panel to add hasn't been set to this component graphical interface and then, no remains without panels in its graphical interface

getActivePanel

IPanel getActivePanel()

Gets a reference to the active panel in this group.

Returns:

a reference to the active panel, or null if there is no any active

getProperties

Hashtable getProperties()

Gets the properties associated to this group of panels.

Returns:

properties associated to this group of panels

getReference

Object getReference()

Gets the object that has a a ''semantically'' or ''conceptually'' relation to this panel.

Returns:

type of object that has reference this panel, or null if there has reference to no object

updateReference

void updateReference(Object reference)

Updates the reference of all elements of the group with the new one.

Parameters:

reference - type of object that has reference this panel, or null if there has reference to no object

setPanelInGUI

void setPanelInGUI(IPanel panel,
                 boolean b)

Changes the visibility of an existent panel of this group. If a panel changes to invisible, then that panel won't be accessible by the user interface. But if changes to visible and was invisible before, then will appear at the same position it was in the user interface. The position is according the order of the insertion at the group. Anyway, the group will have that panel.

Parameters:

panel - reference to the panel with visibility has changed.

b - the new visibility for that panel.

isPanelInGUI

boolean isPanelInGUI(IPanel panel)

Returns true if the panel as parameter belongs to a this group and it's loaded in the graphical user interface; otherwise returns false.

Returns:

true if the panel as parameter belongs to a this group and it's loaded in the graphical user interface; otherwise returns false

getPanelCount

int getPanelCount()

Returns the number of panels registered in this group.

Returns:

number of panels registered in this group

getPanelInGUICount

int getPanelInGUICount()

Returns the number of panels registered in this group that are in GUI.

Returns:

number of panels registered in this group that are in GUI

isAccepted

boolean isAccepted()

Determines if the last notification received has been IPanel.accept().

Returns:

true if that has been the last notification received, false otherwise

setParentPanelGroup

void setParentPanelGroup(IPanelGroup parent)

Sets the parent of this component. That object must be another IPanelGroup component.

Parameters:

parent - parent of this component

accept
