Re: Make action 'generic'

Hej Trevor,

1) Try CookieAction/AbstractAction

https://benkiew.wordpress.com/2012/12/28/netbeans-how-to-create-a-context-aware-action-with-an-icon-for-the-context-menu/

In AbstactAction.isEnabled() you can decide, when the action is enabled

2) Or: Introduce an interface/common parent class for all your DataObjects. Then you can create an action, based on that interface/class. Yes, that works like instanceof.

3) Or: Create an action based the Node type. When executing the action get the data object from the lookup of the Node

BTW: A simple lookup viewer is useful for this task. https://blogs.oracle.com/geertjan/entry/lookup_viewer There are two plugins at the plugin  portal website 

Best regards, markiewb

Ämne: [platform-dev] Make action 'generic'

Hi 
 
I have a set of classes that extend MultiDataObject that read bathymetry data in different formats via a set of readers that pass back a class implementing an interface so that they are all of a type that implements BathymetryAbstractProduct. At a project level I have an action that deletes other files in the project folders when the selected bathymetry file is deleted (since these become invalid). I added the action to the context menu of BathymetryDataNode. However, in the ActionListener the what is being passed to the constructor is the specific MultiDataObject type.
 
As a work around I guess I could enable the action when any DataObject is in the lookup, and rely upon the action only ever being added to BathymetryDataNode – (I have not tried this yet). 
 
Will the above work or is there a better alternative?
 
I would like to write one ActionListener that will work for BathymetryDataNode regardless of the specific MultiDataObject type.
 
Thanks for your help
