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.

Specified by:
translateToGraph in class org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider
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.

Specified by:
translateFromGraph in class org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider
Parameters:
rect - Rectangle that has the values to be translated in graph (pixel) coordinates.
Returns:
Rectangle in logical coordinates.
