Method Summary

Modifier and Type	Method and Description
void	eraseFeedbackData() This method must be called at the end of the edge feedback ( org.eclipse.gef.editpolicies.ConnectionEndpointEditPolicy.eraseConnectionMoveFeedback(ReconnectRequest) or org.eclipse.gmf.runtime.gef.ui.internal.editpolicies.ConnectionBendpointEditPolicy.eraseConnectionFeedback(BendpointRequest, boolean) for example).

void	setFeedbackData(org.eclipse.draw2d.geometry.PointList oldPointList, org.eclipse.draw2d.geometry.Vector oldLabelOffset, boolean isEdgeWithObliqueRoutingStyle) This method must be called before edge feedback creation ( org.eclipse.sirius.diagram.ui.graphical.edit.policies.TreeLayoutConnectionLineSegEditPolicy#showMoveLineSegFeedback(BendpointRequest) or org.eclipse.sirius.diagram.ui.tools.internal.graphical.edit.policies.SiriusConnectionEndPointEditPolicy#showConnectionMoveFeedback(ReconnectRequest) ) for example), to initialize the data needed to compute the label offset dynamically and draw the label feedback correctly. The method eraseFeedbackData() must be called when edge feedback is erase.

Constructor Detail

EdgeLabelLocator

public EdgeLabelLocator(org.eclipse.draw2d.IFigure parent,
                        org.eclipse.draw2d.geometry.Rectangle bounds,
                        int alignment)

Constructor for figure who are located and sized.

Parameters:

parent - the parent figure

bounds - the bounds

alignment - the alignment

Method Detail

setFeedbackData

public void setFeedbackData(org.eclipse.draw2d.geometry.PointList oldPointList,
                            org.eclipse.draw2d.geometry.Vector oldLabelOffset,
                            boolean isEdgeWithObliqueRoutingStyle)

This method must be called before edge feedback creation ( org.eclipse.sirius.diagram.ui.graphical.edit.policies.TreeLayoutConnectionLineSegEditPolicy#showMoveLineSegFeedback(BendpointRequest) or org.eclipse.sirius.diagram.ui.tools.internal.graphical.edit.policies.SiriusConnectionEndPointEditPolicy#showConnectionMoveFeedback(ReconnectRequest) ) for example), to initialize the data needed to compute the label offset dynamically and draw the label feedback correctly.
The method eraseFeedbackData() must be called when edge feedback is erase.

Parameters:

oldPointList - The points list of the edge before to start to move it.

oldLabelOffset - The offset of the label before to start to move the edge.

isEdgeWithObliqueRoutingStyle - The status of the edge routing style

eraseFeedbackData

public void eraseFeedbackData()

This method must be called at the end of the edge feedback ( org.eclipse.gef.editpolicies.ConnectionEndpointEditPolicy.eraseConnectionMoveFeedback(ReconnectRequest) or org.eclipse.gmf.runtime.gef.ui.internal.editpolicies.ConnectionBendpointEditPolicy.eraseConnectionFeedback(BendpointRequest, boolean) for example).

Specified by:

relocate in interface org.eclipse.draw2d.Locator

Overrides:
