palette entry creation trouble [message #151921]

Hi!

I'm wondering how the 'template' and 'factory' parameters of the
CombinedTemplateCreationEntry class constructor interact. I'm trying to
create a number of such palette entries which are supposed to create
objects in the data model of the same class but I need to be able to pass
parameters to them.

I have, say, a list of names

String[] names = { "joe", "alice", "bob" }

and I want to create a CombinedTemplateCreationEntry for each of these. I
don't want to have a separate class for each of the entries (I don't know
them on beforehand), but I want to pass the name to the data model as a
parameter.

How to I accomplish this?

To do this all you need to do is extend CreationFactory and allow it to
accept parameters. So when you instanciate your creation factory pass in
the string ( or what ever ). In the extension you will also want to
over-ride the getNewObject() method and teach it now to create the
correct model object....depending on the parameters you gave it when you
instanciated it.

When you create the CombinedTemplateCreationEntry instance for the
palette entry, give it your CreationFactory instance.

A template can be anything, including a creation factory if you want.

Yes, but what do you do with the template? How do you use it if you
subclass your own CreationFactory?

The template is used by the Template Drop target listener. Similar to the
creation tool, it will turn a native drop into a CreateRequest.
