public AbstractListenableRenderSettings()

Method Detail

setSettingsChangeHandler

public void setSettingsChangeHandler(com.levigo.jadice.document.render.SettingsChangeHandler changeHandler)

Sets a SettingsChangeHandler for this settings instance. A change handler is responsible to propagate internal setting changes to its owning RenderSettings which feeds registered RenderSettingsListener with RenderSettingsEvents.

It is strongly recommended not to change the SettingsChangeHandler reference by a call of this method because it could cause faulty event propagation issues.

To retrieve RenderSettingsEvents of a specific DefaultRenderControls instance register a RenderSettingsListener at the DefaultRenderControls to be observed. Use therefore the the DefaultRenderControls.addRenderSettingsListener(RenderSettingsListener) method.

To retrieve render setting changes as a InventoryRenderSettingsEvent for a RenderControlInventory use a InventoryRenderSettingsListener which can be registered with a call of RenderControlInventory.addInventoryRenderSettingsListener(InventoryRenderSettingsListener).

Parameters:

changeHandler -

getSettingsChangeHandler

public com.levigo.jadice.document.render.SettingsChangeHandler getSettingsChangeHandler()

Gets a SettingsChangeHandler for this settings instance. See setSettingsChangeHandler(SettingsChangeHandler) for detailed informations.

Returns:

the changeHandler

fireChanged

protected void fireChanged(String settingName,
                           Object oldValue,
                           Object newValue)
