Hmmm. It isn't the SLDDropAction that is consuming the event it sounds
like the WizardDropAction is consuming the event. I think you may have
found a bug. I'm looking at the code and it seems to always accept the
string regardless of whether it can understand it. That said I'm not
sure why your extension is not being called. As far as I know the code
does not consume the data. All the actions that are valid should be ran.
Have you put a break point in the accept method to see if it is being
called?

Hi!
I am probably asking a stupid question, but I have written a small
plugin to accept a string drop and display a message of the string,
(just to get started).
The problem is, I am not sure my code ever gets activated.
I assume that SLDDropAction code is taking the action before it gets to
me?
My project,xml action is:
<extension point="net.refractions.udig.ui.dropAction">
<action
class="net.refractions.udig.test1.actions.StringDropAction"
name="String Drag and Drop">
<destination class="net.refractions.udig.project.ILayer"/>
<acceptedType class="java.lang.String"/>
</action>
</extension>
StringDropAction class extends IDropAction.
Am I on the right track?
What do I need to do to get my code to be able to process the drop?
All I get is a dialog window come up asking me to select a data source.
Thanks
Michelle

I am trying to understand how to start approaching the D&D stuff I need
to do. If I drop a string or image file onto a Map, I assume it would
need to create a new layer in the layer manager (and assuming I have
programmed where), ultimately store the data in the database and then
render the feature.
Are you going to be developing on uDig 1.1 or 1.0.x? I have done a lot
of the difficult work so there is a nice framework for 1.1 but the
downside is that it not being released until later this month. I don't
know what your timeline is like.
You can look at
net.refractions.udig.project.ui.internal.actions.DropAction for an
example of an action taken when a url is dropped on a a layer. The
declaration of the drop action in the project.xml goes something like:
<action
class="net.refractions.udig.project.ui.internal.actions.SLDDropAction"
name="SLD Drag and Drop">
<destination class="net.refractions.udig.project.ILayer"/>
<acceptedType class="java.io.File"/>
<acceptedType class="java.net.URL"/>
<acceptedType class="java.lang.String"/>
</action>
I'm going to put this example in the drag and drop documenation I wrote
for you.
So I need to deal with Map, LayerManager, RenderManager, Catalogue,
Feature and probably more? Ahhh! I feel sleepless nights coming on.
This depends on the work flow and requirements. Suppose you drop a
string on layer in LayersView and the drop action creates a feature by
interpreting the string and adds it to the layer. In this case can use
the Layer.getResource() method to get a FeatureStore (Class used for
adding/removing features from a datastore) and add the feature using the
FeatureStore. In this case all you need to know is the Layer and
FeatureStore API.
Now suppose you drop a image that some how specifies a layer and all the
features in the layer. In this case you need to know Map, Layer,
Catalog, Feature, DataStore, etc...
Hope this helps.
Jesse
