All Implemented Interfaces:

public class VMDNodeWidget
extends Widget
implements StateModel.Listener, VMDMinimizeAbility

This class represents a node widget in the VMD visualization style. It implements the minimize ability. It allows to add pin widgets into the widget using attachPinWidget method.

The node widget consists of a header (with an image, a name, secondary name and a glyph set) and the content. The content contains pin widgets. Pin widgets can be organized in pin-categories defined by calling sortPins method. The sortPins method has to be called refresh the order after adding a pin widget.

Constructor Details

VMDNodeWidget

public VMDNodeWidget(Scene scene)

Creates a node widget.

Parameters:

scene - the scene

VMDNodeWidget

public VMDNodeWidget(Scene scene,
 VMDColorScheme scheme)

Creates a node widget with a specific color scheme.

Parameters:

scene - the scene

scheme - the color scheme

Method Details

isMinimizableWidget

protected boolean isMinimizableWidget(Widget widget)

Called to check whether a particular widget is minimizable. By default it returns true. The result have to be the same for whole life-time of the widget. If not, then the revalidation has to be invoked manually. An anchor (created by VMDNodeWidget.createPinAnchor is not affected by this method.

Parameters:

widget - the widget

Returns:

true, if the widget is minimizable; false, if the widget is not minimizable

isMinimized

public boolean isMinimized()

Check the minimized state.

Returns:

true, if minimized

setMinimized

public void setMinimized(boolean minimized)

Set the minimized state. This method will show/hide child widgets of this Widget and switches anchors between node and pin widgets.

Parameters:

minimized - if true, then the widget is going to be minimized

toggleMinimized

public void toggleMinimized()

Toggles the minimized state. This method will show/hide child widgets of this Widget and switches anchors between node and pin widgets.

stateChanged

public void stateChanged()

Called when a minimized state is changed. This method will show/hide child widgets of this Widget and switches anchors between node and pin widgets.

Specified by:

stateChanged in interface StateModel.Listener

notifyStateChanged

protected void notifyStateChanged(ObjectState previousState,
 ObjectState state)

Called to notify about the change of the widget state.

Overrides:

notifyStateChanged in class Widget

Parameters:

previousState - the previous state

state - the new state

setNodeImage

public void setNodeImage(Image image)

Sets a node image.

Parameters:

image - the image

getNodeName

public String getNodeName()

Returns a node name.

Returns:

the node name

setNodeName

public void setNodeName(String nodeName)

Sets a node name.

Parameters:

nodeName - the node name

setNodeType

public void setNodeType(String nodeType)

Sets a node type (secondary name).

Parameters:

nodeType - the node type

attachPinWidget

public void attachPinWidget(Widget widget)

Attaches a pin widget to the node widget.

Parameters:

widget - the pin widget

setGlyphs

public void setGlyphs(List<Image> glyphs)

Sets node glyphs.

Parameters:

glyphs - the list of images

setNodeProperties

public void setNodeProperties(Image image,
 String nodeName,
