Interface ContextMenuRequest<E extends Edge>

Type Parameters:

E - the edge type of the rendered graph

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ContextMenuRequest<E extends Edge>

Notification fired by CanvasInteraction when the user triggers a context-menu request (right button, or Control+click on macOS). The listener receives the pointer position in view coordinates and the element under the pointer, if any; the actual menu is built in a later phase (N4), so this phase only delivers the request.

Method Details

request

void request(@Nonnull
 Point2D viewPoint,
 @Nullable

 @Nullable
 E edge)

Delivers a context-menu request.

Parameters:

viewPoint - the pointer position in view (component) coordinates, not null

edge - the edge under the pointer, or null if there is none. When node is not null this is always null: a node hit takes precedence over an edge hit
