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.

static byte	FIXED_AUTOBOUNDS_INSETS Group bounds policy specifier.
static byte	FIXED_MINIMUM_GROUP_BOUNDS Group bounds policy specifier.

Field Detail

FIXED_AUTOBOUNDS_INSETS

public static final byte FIXED_AUTOBOUNDS_INSETS

Group bounds policy specifier. When resizing a node that belongs to a group whose realizer implements AutoBoundsFeature, the group node's autoBoundsInsets will stay fixed. It's overall bounds can grow or shrink.

Constant Field Values

FIXED_MINIMUM_GROUP_BOUNDS

public static final byte FIXED_MINIMUM_GROUP_BOUNDS

Group bounds policy specifier. When resizing a node that belongs to a group whose realizer implements AutoBoundsFeature, the group node's bounds can grow but not shrink. Before a group node starts to grow its autoBoundsInset will be reduced, first.

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.

mouseReleased

public void mouseReleased(MouseEvent ev)

Perform additional cleanup.

Specified by:

mouseReleased in interface MouseListener

Overrides:

mouseReleased in class ViewMode

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 modified by changing their autobounds insets.

Overrides:

updateNodeRealizerBounds in class HotSpotMode

Parameters:

vr - the realizer of the node whose bounds should 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.

See Also:

Also checks if the realizer provides a {@link SizeConstraintProvider} and adjusts the resizing so that it will keep to the restrictions given by that provider., SizeConstraintProvider

getGroupBoundsPolicy

public byte getGroupBoundsPolicy()

Returns the group bounds policy used when resizing the child nodes of a group.

Returns:

Returns one of FIXED_AUTOBOUNDS_INSETS and FIXED_MINIMUM_GROUP_BOUNDS.

setGroupBoundsPolicy

public void setGroupBoundsPolicy(byte groupBoundsPolicy)

Sets the group bounds policy used when resizing the child nodes of a group. By default, FIXED_AUTOBOUNDS_INSETS is set.

Parameters:

groupBoundsPolicy - one of FIXED_AUTOBOUNDS_INSETS and FIXED_MINIMUM_GROUP_BOUNDS.
