Method Detail

getCell

Object getCell()

Returns the model object that this view represents.

refresh

void refresh(boolean createDependentViews)

Refresh this view based on the model cell. This is messaged when the model cell has changed.

update

void update()

Update this view's attributes. This is messaged whenever refresh is messaged, and additionally when the context of the cell has changed, and during live-preview changes to the view.

childUpdated

void childUpdated()

getParentView

CellView getParentView()

Returns the parent of view of this view.

getChildViews

CellView[] getChildViews()

Returns the child views of this view.

removeFromParent

void removeFromParent()

Removes this view from the list of childs of the parent.

isLeaf

boolean isLeaf()

Returns true if the view is a leaf.

getBounds

Rectangle getBounds()

Returns the bounds for the view.

intersects

boolean intersects(Graphics g,
                   Rectangle rect)

Returns true if the view intersects the given rectangle.

setAttributes

Map setAttributes(Map map)

Apply the specified map of attributes on the view.

getAttributes

Map getAttributes()

Returns all attributes of the view as a map.

getAllAttributes

Map getAllAttributes()

getRendererComponent

Component getRendererComponent(JGraph graph,
                               boolean selected,
                               boolean focus,
                               boolean preview)

Returns a renderer component, configured for the view.

getHandle

CellHandle getHandle(GraphContext context)

Returns a cell handle for the view.

getEditor

GraphCellEditor getEditor()

Returns a cell editor for the view.
