setDragDetect method [message #647975]

Hi,

I was using the Treeviewer#setDragDetect method in an RCP application and wanted to use it in the RAP application.
But this method doesn't exists.

Is there a descent way to have the same behaviour ? (ie. remove the drag feature from a component).

Thanks,

Cedric,

setDragDetect is a method on Control and currently not available in RAP.
The recommended way to enable DND in JFace viewers is by using
StructuredViewer#addDragSupport and addDropSupport.

You may open an enhancement request if you think that you have a valid
use case for setDragDetect.

BTW, are you aware of these two articles?
http://www.eclipse.org/articles/Article-SWT-DND/DND-in-SWT.h tml

Thank you for your response.

Actually, the setDragDetect method was used with a "false" parameter. This is used in some cases to disable the drag behaviour from a control.

So, in RAP, there is a method to add the drag (addDragSupport), there is nothing to remove the drag feature. (like removeDragSupport).

Feel free to open an enhancement request if you need a way to 'globally'
disable DND.
In the meanwhile you can use the DragSourceListener#dragStart() event to
prevent dragging.

These APIs aren't specific to RAP, they are provided by JFace.
