Hey all, Three questions that have come up in coding uDig
1) Java: can object instances be retyped dynamically? Consider 'InterfaceA', and 'InterfaceB extends IA' where this simply adds a method. Is it possible to take an instance of A and somehow add a definintion of the required method to promote Ainstance to Binstance? Sorry, I'm sure there is terminology for this but I don't know it. 2) Eclipse: Can Views be created in a Dialog and then embedded? Views can be 'torn-off' from eclipse in their own window. I wan the opposite. I'd like to create a view which is presented in a dialog by default. This would require that it has a "Run Operation" button. However, I want the essentials of the content to be in a view so that power users could simply embed the view in their uDig GUI to be able to run several operations one after the other. Is this possible? Does this require having an apply 'check mark' like in the 'Style' view? Anyone know of docs to get started? 3) uDig/Geotools: How do we use FactoryFinders? I'm kind of confused by all the Factories, FactoryBuilders and FactoryFinders around. It seems there are several FactoryFinders which means we have to find the Finders. Is there an explanation of what each of them do? Is the idea eventually to have a single 'FactoryFinder' instance that does really find all the factories for all the different types of objects? thanks in advance for any answers, adrian _______________________________________________ User-friendly Desktop Internet GIS (uDig) http://udig.refractions.net http://lists.refractions.net/mailman/listinfo/udig-devel
