Examples with LayoutConstraint org.eclipse.gmf.runtime.notation.LayoutConstraint used on opensource projects

Example 1 with LayoutConstraint

use of org.eclipse.gmf.runtime.notation.LayoutConstraint in project statecharts by Yakindu.

the class SetLabelsOffsetOperation method updateGMFLabelsOffset.

/**
 * Update the offset ({@link Bounds}) of the labels {@link Node}. This method
 * must be called after setting the newPointList and the labelToUpdate. If the
 * methods {@link #setLabelsToUpdate(ConnectionEditPart)} or
 * {@link #setLabelsToUpdate(ConnectionEditPart, PointList)} are not called,
 * this method has no effect.
