Method Detail

getName

public abstract java.lang.String getName()

stop

public void stop()

When the canvas loses focus, the shape should be "cancelled" For an obox, this means removing the partly constructed shape. For a bbox, this means the same. For a polygon, it means to consider the current shape complete and add it (this is because of the difficulty of drawing a many sided polygon)

displaySelected

public abstract void displaySelected()

getAttribute

public Attribute getAttribute()

Returns:

setAttribute

public void setAttribute(Attribute attribute)

Parameters:

getAssistant

public CreatorAssistant getAssistant()

Returns:

setAttrValueInMediator

public void setAttrValueInMediator(java.lang.Object val)
