CompositeLeftRightProvider

public CompositeLeftRightProvider()
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.

createGraph

protected DirectedGraph createGraph()
Description copied from class: org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider
Creates the graph that will be used by the layouy provider Clients can override this method create different kind of graphs This method is called by DefaultProvider.layoutEditParts(GraphicalEditPart, IAdaptable) and DefaultProvider.layoutEditParts(List, IAdaptable)

Overrides:
createGraph in class org.eclipse.gmf.runtime.diagram.ui.providers.internal.CompositeLayoutProvider
Returns:
the Graph that will be used by the layout algorithm

getLayoutDirection

protected int getLayoutDirection(GraphicalEditPart ep)
Description copied from class: org.eclipse.gmf.runtime.diagram.ui.providers.internal.CompositeLayoutProvider
Gets the layout direction for an editpart. Every editpart mapped to AdvancedSubGraph will be asked for its desired layout direction such that children of the subgraph are laid out accordingly to that direction.

Overrides:
getLayoutDirection in class org.eclipse.gmf.runtime.diagram.ui.providers.internal.CompositeLayoutProvider
Parameters:
ep - the editpart
