Mac OS X drag and drop [message #445481] Sat, 06 November 2004 15:50 Go to next message

Hi,

I have a plugin which implements drag and drop using LocalTransfer.
It works fine on Win32 and Linux but not on`Mac OS X.

I'm using Eclipse 3.01 on all platforms. On Mac OS X with debug statements
I can see that dragStart() is called on my drag dource control. But no drop
is detected or called on my drop target.

I'm using the org.eclipse.core.runtime.adapters extension in my plugin to
add the drop target listener to an editor from another plugin and I can see
from my debugging output that my listern factory and my listener instance
are created. Yet no drop target methods are called.

Bugzilla shows Mac OS X drag and drop problems to have been fixed earlier
this year.

Does anyone have a similar problem, or a workaround?

Thanks,
Mike

Do you provide any data in the dragSetData event notification on the
DragSource? If not, you will not be able to perform a drag and drop on Mac
OSX.

Thank you, that works. Why the platform difference. I followed an example i
found on the web with data set in the dragStart() ,using
LocalSelectionTransfer and it works fine on Win an Linux.

I shall make all other platforms stop working if no data is provided in the
dragSetData because that is the correct behaviour - in 3.1 we are focusing
on consistency and I will enforce this behaviour. The
LocalSelectionTransfer example you found is wrong. Do you know where you
found it? If it is in eclipse documentation I will get it fixed.
