Method Detail

addSpanModelListener

public void addSpanModelListener(SpanModelListener l)

Adds a listener to the list that's notified each time a change to the span model occurs. The implementation uses a simple Vector, but also handles the case where a manager is added, ensuring it is only present once, and always before any non-managers position.

Specified by:

addSpanModelListener in interface SpanModel

Parameters:

l - the SpanModelListener

removeSpanModelListener

public void removeSpanModelListener(SpanModelListener l)

Removes a listener from the list that's notified each time a change to the data model occurs.

Specified by:

removeSpanModelListener in interface SpanModel

Parameters:

l - the SpanModelListener

propagateDataChange

protected void propagateDataChange(SpanModelEvent e)

Implements the mechanism thats fires an event-oriented data change.

propagateModelChange

protected void propagateModelChange(SpanModelEvent e)

Implements the mechanism that fires an event-oriented model change.

propagateStructureChange

protected void propagateStructureChange(SpanModelEvent e)

this method implements the mechanism to fire a event oriented structure changed.

fireSpanModelChanged

public void fireSpanModelChanged()

Forwards the given notification event to all SpanModelListeners that registered themselves as listeners for this table model.

addSpanModelListener(com.eliad.model.SpanModelListener), SpanModelEvent, EventListenerList

fireSpanStructureChanged

protected void fireSpanStructureChanged(int type,
                                        int first,
                                        int count)

Forwards a "structure incrementally changed" notification event to all SpanModelListeners that registered themselves as listeners for this span model.

fireSpanAdded

public void fireSpanAdded(int anchorRow,
                          int anchorColumn,
                          int newRowCount,
                          int newColumnCount)
