public RenderableBase()

Method Detail

isSelectable

public boolean isSelectable()

Returns true if this object is in fact selectable.

Specified by:

isSelectable in interface IsSelectable

Returns:

true if this object is selectable

numSelectionQueriesNeeded

public int numSelectionQueriesNeeded()

If this selectable manages its own selection (by issuing selection queries within its render method), then this method should return the maximum number of selection queries that will be required. Otherwise, this method should return -1.

Specified by:

numSelectionQueriesNeeded in interface IsSelectable

Returns:

maximum number of selection queries needed by this component, or -1 if this component does not manage its own selection.

getSelection

public void getSelection(java.util.LinkedList<java.lang.Object> list,
                         int qid)

Append to list the component (or components) associated with the qid-th selection query issued by this component's render method. This will only be called if this component manages its own selection (i.e., the number nums returned by IsSelectable.numSelectionQueriesNeeded() is positive), and qid will in turn be a number between 0 and nums-1.

Specified by:

getSelection in interface IsSelectable

Parameters:

list - selected objects are appended to the end of this list

qid - index of the selection query

getRenderProps

public RenderProps getRenderProps()

Returns the render properities for this object. If no render properties are assigned, this routines returns null.

Specified by:

getRenderProps in interface HasRenderProps

Returns:

current render properties for this object

setRenderProps

public void setRenderProps(RenderProps props)

Assigns a new set of render properties to this object. An argument of null will remove render properties from this object.

Specified by:

setRenderProps in interface HasRenderProps

Parameters:

props - new render properties for this object
