Constructor Detail

BpmnMarkerDecorator

public BpmnMarkerDecorator(AbstractBpmnPainter delegate)

Initializes a new BpmnMarkerDecorator instance.

Parameters:

delegate - the decorated painter.

Method Detail

getIconBoundingBox

protected Rectangle2D getIconBoundingBox(NodeRealizer context,
                                         Rectangle2D availableRegion)

Description copied from class: BpmnIconDecorator

Determines the bounds of the icon that is painted by this decorator. Called from BpmnIconDecorator.getIconBoundingBox(y.view.NodeRealizer).

Specified by:

getIconBoundingBox in class BpmnIconDecorator

Parameters:

context - the visual representation of the node being painted.

availableRegion - the region in which the icon bounds should lie.

Returns:

the location and size of the icon is painted by this decorator.

getIconPainter

protected BpmnIconPainter getIconPainter(NodeRealizer context)

Returns a painter painting all marker icons for the specified node.

Specified by:

getIconPainter in class BpmnIconDecorator

Parameters:

context - the visual representation of the node to paint.

Returns:

a painter painting all marker icons for the specified node.

getMarkerIconPainter

protected BpmnIconPainter getMarkerIconPainter(MarkerTypeEnum type)

Retrieves an icon painter for the specified marker type.

Parameters:

type - the marker type.

Returns:

an icon painter for the specified marker type or null if there is no painter for the specified type.

findMouseInputEditor

public MouseInputEditor findMouseInputEditor(NodeRealizer context,
                                             Graph2DView view,
                                             double x,
                                             double y,
                                             HitInfo hitInfo)

Returns an editor to handle mouse events for group/folder nodes that are configured to use this BpmnMarkerDecorator instance as their GenericNodeRealizer.GenericMouseInputEditorProvider. By default, a GroupNodePainter.GroupStateEditor instance is returned that closes groups/opens folders when the node's group state icon is clicked.

Specified by:

findMouseInputEditor in interface GenericNodeRealizer.GenericMouseInputEditorProvider

Parameters:

context - the node context.

view - the component that received the mouse event.

x - the x-component of the world (graph) coordinate of the event.

y - the y-component of the world (graph) coordinate of the event.

hitInfo - the elements of the specified view's graph at the event location.

Returns:

a MouseInputEditor instance that handles mouse events at the given coordinates or null if events at the given coordinates are ignored.

isStateIconHit(y.view.NodeRealizer, double, double), GroupNodePainter.GroupStateEditor

isStateIconHit

protected boolean isStateIconHit(NodeRealizer context,
                                 double x,
                                 double y)

Checks whether or not the specified coordinates lie inside the specified node's group state icon. The default implementation checks whether or not the coordinates lie inside either the icon corresponding to MarkerTypeEnum.OPEN or MarkerTypeEnum.CLOSED.

Parameters:

context - the visual representation of the node to check.

x - the x-coordinate to check.

y - the y-coordinate to check.

Returns:

true if the specified coordinates lie inside a group state icon; false otherwise.

getMaximumSize

public YDimension getMaximumSize(NodeRealizer context)

Specified by:

getMaximumSize in interface GenericNodeRealizer.GenericSizeConstraintProvider

getMinimumSize

public YDimension getMinimumSize(NodeRealizer context)

Specified by:

getMinimumSize in interface GenericNodeRealizer.GenericSizeConstraintProvider
