GEF does not provide drag and drop functionality by default. So the way to go would be a custom implementation for SWT Drag and Drop. The SWT Control for the GEF viewer is the FXCanvas that is constructed by AbstractFXEditor. You can access the FXCanvas using the getCanvas() accessor, which, unfortunately, is protected, so a subclass is needed in order to expose that FXCanvas.
Adding/Manipulating content in response to SWT Drag and Drop can be done via default policies and operations, though, e.g. ContentPolicy: https://github.com/eclipse/gef/blob/master/org.eclipse.gef.mvc.fx/src/org/eclipse/gef/mvc/fx/policies/ContentPolicy.java
edit: The IOnDragHandler interface is used for handling mouse press drag release inside JavaFX.
