| RE: [udig-devel] Drag and Drop and beyond. |
Hi!
Did this get fixed? (see email below)
I still can't get my string to be accepted on the drop.
The dragStart and dragSourceData methods in the DragListener on the
source object get called fine.
But the accept method of the Drop class never gets called.
(Not even the construtor of the Drop class seems to get called!).
Not sure if it is something I am doing wrong.
The extension code I have is:
<extension point="net.refractions.udig.ui.dropAction">
<action
class="info.ecosensus.udig.actions.IconDropAction"
name="Icon Drag And Drop">
<destination
class="net.refractions.udig.project.ILayer"/>
<acceptedType class="org.eclipse.swt.widgets.Table"/>
</action>
</extension>
(was not sure what the accetedType should be. I have tried various
things)
I have attached the IconDropAction class (drop) and the IconView class
(drag source)
Any ideas?
Michelle

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?
