What steps do I need to take to implement a more PowerPoint-like way of selecting and moving nodes?

This means that the user will select a shape by pressing the mouse button, but the button keeps pressed while the user is moving the selected shape.

When just I use the following methods to setup my diagram application ...

diagramView.setBehavior(Behavior.Modify);

shapeNode.setHandlesStyle(HandlesStyle.MoveOnly);

... the user has to release the mouse button, move the mouse cursor a little, then mouse cursor will change its shape, then he has to press the button again, and finally he can move the shape. This behavior is a bit inconvenient.
