Sandeep,
If your datasource returns paths, your view should be automatically a
drag source.
If your datasource returns images, I think the only thing you have to
do is to implement
- (NSUInteger) imageBrowser:(IKImageBrowserView *) aBrowser
writeItemsAtIndexes:(NSIndexSet *) itemIndexes toPasteboard:
(NSPasteboard *)pasteboard;
in your datasource and fill the pasteboard with the info you want for
the specified indexes.

I did try the -setDraggingDestinationDelegate: , but it is meant
for a drag
destination and not drag source. From the documentation (here:
http://developer.apple.com/documentation/Cocoa/Conceptual/DragandDrop/Concepts/dragsource.html#//apple_ref/doc/uid/20000976-CJBFBADF
)
I have to implement draggingSourceOperationMaskForLocal and invoke
dragImage:at:offset:event:pasteboard:source:slideBack: in
mouseDown: or
mouseDragged: method to make it a drag source. I have a NSView
subclass,
that is a delegate of the IKImageBrowserView view and have
implemented the
methods above, yet these never get called.
Also I tried setting the class of the IKImageBrowserView object to
my custom
class, only then would the - mouseDragged: even would work, but I
lost a
bunch of other IKImageBrowserView features (such as cell selection
etc).

Sandeep,
Did you set the dragging destination delegate using

Greetings,
In my app I have an IKImageBrowserView, and I want to make this an
drag
source. I have followed thedragging source
docs<
http://developer.apple.com/documentation/Cocoa/Conceptual/DragandDrop/Concepts/dragsource.html#//apple_ref/doc/uid/20000976
but
to no avail. In my view class the mouseDragged never gets called.
Any help
on making the IKImageBrowserView a drag source or making it
respond to
mouseDragged even is appreciated. Thanks.
