Method Detail

translateToGraph

protected Rectangle translateToGraph(Rectangle r)

Description copied from class: org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider

Retrieves the extent and position from the given logical rectangle in GEF graph coordinates. Defined as abstract to allow subclasses to implement to perform a transformation on the values stored in the node. i.e. support for Left-Right layout as opposed to Top-Down.

Returns:

Rectangle in graph coordinates.

translateFromGraph

protected Rectangle translateFromGraph(Rectangle rect)

Description copied from class: org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider

Retrieves the logical extent and position from the given rectangle. Defined as abstract to allow subclasses to implement to perform a transformation on the values stored in the node. i.e. support for Left-Right layout as opposed to Top-Down.

Parameters:

rect - Rectangle that has the values to be translated in graph (pixel) coordinates.

Returns:

Rectangle in logical coordinates.
