Hello everyone,

I'm trying to make my own tooltip on some nodes (called "Input") of my GMF editor. In order to do this, I set a MouseMotionListener to my InputFigure to display my tooltip when the mouse is hovering the node.

Everything works fine, but I would want to display my tooltip during the creation of a link whose target is my Input node. The problem is, none of the listener's methods is called when a link is being created.

How can I proceed ?

PS: I did not use the "setTooltip()" method for the same reason; the tooltip does not appear during the creation of a link.

Hi,

as far as I can understand you want to draw a connection between two model elements and show a menu which lets the user select what to create when releasing the mouse at the target. To do so install a customized GraphicalNodeEditPolicy into your edit parts. This class shows such a GraphicalNodeEditPolicy http://code.google.com/a/eclipselabs.org/p/melanie/source/browse/de.uni_mannheim.informatik.swt.common.gmf.inthemiddle/src/de/uni_mannheim/informatik/swt/common/gmf/inthemiddle/gnep/ITMGraphicalNodeEditPolicy.java The method getConnectionMenuContent(CreateConnectionRequest request) is of interest here. An example for a template which installs this policy into an EditPart can be found here: http://code.google.com/a/eclipselabs.org/p/melanie/source/browse/de.uni_mannheim.informatik.swt.models.gmf/templates/aspects/impl/diagram/editparts/NodeEditPart.xpt The part «AROUND createDefaultEditPoliciesBody FOR gmfgen::GenNode-» is of interest in this template. A video that shows the result can be found here: http://code.google.com/a/eclipselabs.org/p/melanie/wiki/FirstSteps#Creat_DSL_Connection
