public class IlvZoomOutAction
extends IlvAction

The IlvZoomOutAction class implements an action that will zoom out on a specified IlvTimeScrollable. Typically, this will be an IlvHierarchyChart. When an IlvZoomOutAction is created, it registers an internal, private event listener with the IlvTimeScrollable so that the action can automatically enable and disable itself appropriately. If, at a later time, you want to remove the IlvZoomOutAction from the user interface and have it garbage-collected, you will need to explicitly call the removeFromTimeScrollable() method.

Constructor Detail

IlvZoomOutAction

public IlvZoomOutAction(IlvTimeScrollable timeScrollable,
                        String name,
                        KeyStroke accelerator,
                        String shortDescription,
                        String longDescription)

Creates an IlvZoomOutAction for the specified IlvTimeScrollable object with a default icon. Typically, the scrollable will be an IlvHierarchyChart. When an IlvZoomOutAction is created, it registers an internal, private event listener with the IlvTimeScrollable so that the action can automatically enable and disable itself appropriately. If, at a later time, you want to remove the IlvZoomOutAction from the user interface and have it garbage-collected, you will need to explicitly call the removeFromTimeScrollable() method.

Parameters:

timeScrollable - The time scrollable object that will be zoomed by the action.

name - The name of the action. If the action is added to a JMenu, the name will be used as the menu item text. If the action is added to a JToolBar, the name will be used as the button text.

accelerator - The action's optional keyboard accelerator.

shortDescription - The action's optional short description. This text, if not null, will be typically used for tooltips.

longDescription - The action's optional long description. This text, if not null, will be typically used for display in a status bar.

IlvZoomOutAction

public IlvZoomOutAction(IlvTimeScrollable timeScrollable,
                        String name,
                        Icon icon,
                        KeyStroke accelerator,
                        String shortDescription,
                        String longDescription)

Creates an IlvZoomOutAction for the specified IlvTimeScrollable object. Typically, this is will be an IlvHierarchyChart. When an IlvZoomOutAction is created, it registers an internal, private event listener with the IlvTimeScrollable so that the action can automatically enable and disable itself appropriately. If, at a later time, you want to remove the IlvZoomOutAction from the user interface and have it garbage-collected, you will need to explicitly call the removeFromTimeScrollable() method.

Parameters:

timeScrollable - The time scrollable object that will be zoomed by the action.

name - The name of the action. If the action is added to a JMenu, the name will be used as the menu item text. If the action is added to a JToolBar, the name will be used as the button text.

icon - The action's icon or null to use the default icon.

accelerator - The action's optional keyboard accelerator.

shortDescription - The action's optional short description. This text, if not null, will be typically used for tooltips.

longDescription - The action's optional long description. This text, if not null, will be typically used for display in a status bar.
