Field Detail

resizeCursors

public static final transient int[] resizeCursors

Array that holds the cursors for the different control points.

Constructor Detail

TCObjectView

public TCObjectView(Object cell,
                    TCGraph graph,
                    org.jgraph.graph.CellMapper mapper,
                    boolean createIcon)

Creates a new instance of TCObjectView.

Parameters:

cell - cell the view is created for

graph - graph the view is created for

mapper - cell mapper

createIcon - create icon if it does not exist

Method Detail

createStaticRenderer

protected abstract void createStaticRenderer()

Called when static renderer should be lazilly created. If the renderer does not exist yet, it will be created. In case that some TCObject does not use a static renderer, this should be overriden with an empty implementation.

setInitialAttributes

protected abstract void setInitialAttributes(Map map)

Called when the initial attributes are needed.

Parameters:

map - map attributes should be set to

createIcon

protected void createIcon()

Called when icon should be created and getIcon() returns null at the initialization time. This implementation searches the icon at default resources using key _icon, where the class name is lowercased.

getIcon

protected abstract Icon getIcon()

Returns the icon of the TCObject.

Returns:

icon of the TCObject or null if the view does not use an icon

setIcon

protected abstract void setIcon(Icon icon)

Sets the icon of the TCObject.

Parameters:

icon - icon to set

getRenderer

public abstract org.jgraph.graph.CellViewRenderer getRenderer()

Returns:

renderer for TCObjectView

getHandle

public org.jgraph.graph.CellHandle getHandle(org.jgraph.graph.GraphContext context)

Parameters:

context - GraphContext (cell-view) the handle is created for

Returns:

handle for given context

isAloneInSelection

public boolean isAloneInSelection()

Returns:

true if this cell view is the only one in the selection.

getEditor

public abstract org.jgraph.graph.GraphCellEditor getEditor()

Returns the editor for given component

getMinimumUsableSize

public Dimension getMinimumUsableSize()

Returns:

mimimum usable size

getMaximumUsableSize

public Dimension getMaximumUsableSize()

Returns:

mimimum usable size

resetAutoSizeConstraints

public abstract void resetAutoSizeConstraints(Map map,
                                              boolean min,
                                              boolean max)

Resets autosize constraints

Parameters:

map - map to save changes to

min - whether to reset `minimum' constraint

max - whether to reset `maximum' constraint

resetAutoSizeConstraints

public final void resetAutoSizeConstraints(Map map,
                                           Dimension usable,
                                           Dimension fixed,
                                           boolean min,
                                           boolean max)

Method providing some common code for resetting auto-size constraints. Constrains are also corrected to be consistent.

Parameters:

map - map to save changes to

usable - dimension that can be used as usable

fixed - dimension that cannot be used as usable

min - whether to reset `minimum' constraint

max - whether to reset `maximum' constraint

initSizes

protected final void initSizes(Map map)

Initializes size parameters to reasonable values

updateTCObjectContainerEntryPlacementContext

public void updateTCObjectContainerEntryPlacementContext(TCObjectView.TCObjectContainerEntryPlacementContext pc,
                                                         TCObjectContainer[] containers,
                                                         Rectangle bounds)

Updates the given TCObjectContainerEntry placement context

Parameters:

pc - TCObjectContainerEntryPlacementContext to update

containers - containers available for placement

bounds - new bounds of the placed view (this)

computeTCObjectContainerEntryInsertionBounds

public Rectangle computeTCObjectContainerEntryInsertionBounds(TCObjectView.TCObjectContainerEntryPlacementContext placementContext)

Computes bounds to be displayed as insertion area of the moved TCObjectContainerEntry.

Parameters:

placementContext - TCObjectContainerEntryPlacementContext

Returns:

bounds to be displayed or null if there is no place to insert the TCObjectContainerEntry
