public class HierarchyHotSpotMode

extends HotSpotMode

A specialized HotSpotMode suitable for editing hierarchically organized graphs. This modes uses a special resize policy for NodeRealizers that represent group nodes and consequentially implement AutoBoundsFeature. Such nodes may be resized to a limited degree by changing their auto bounds insets.

Constructor Detail

HierarchyHotSpotMode

public HierarchyHotSpotMode(ViewContainer vc)

Instantiates a new HierarchyHotSpotMode for a given ViewContainer

HierarchyHotSpotMode

public HierarchyHotSpotMode()

Instantiates a new HierarchyHotSportMode.

Method Detail

mousePressedLeft

public void mousePressedLeft(double x,
                             double y)

Initiates resizing of selected nodes.

Overrides:

mousePressedLeft in class HotSpotMode

Parameters:

x - the x-coordinate of the mouse event in world coordinates.

y - the y-coordinate of the mouse event in world coordinates.

updateNodeRealizerBounds

protected void updateNodeRealizerBounds(NodeRealizer vr,
                                        double x,
                                        double y,
                                        double w,
                                        double h)

Special handling of NodeRealizers that implement AutoBoundsFeature. The bounds of such realizers are modifed by changing their autobounds insets.

Overrides:

updateNodeRealizerBounds in class HotSpotMode

Parameters:

vr - the realizer of the node whose bounds shoud change.

x - the desired x-coordinate of the node bounds.

y - the desired y-coordinate of the node bounds.

w - the desired width of the node.

h - the desired height of the node.
