<pre>public class <span class="typeNameLabel">mxCellMarker</span>

<div class="block">Implements a mouse tracker that marks cells under the mouse.
This class fires the following event:
mxEvent.MARK fires in mark and unmark to notify the listener of a new cell
under the mouse. The <code>state</code> property contains the mxCellState
of the respective cell or null if no cell is under the mouse.
To create a cell marker which highlights cells "in-place", the following
code can be used:
<code>
mxCellMarker highlighter = new mxCellMarker(graphComponent) {
protected Map<String, Object> lastStyle;
public mxCellState process(MouseEvent e)
{
mxCellState state = null;
if (isEnabled())
{
state = getState(e);
boolean isValid = (state != null) ? isValidState(state) : false;
if (!isValid)
{
state = null;
}
highlight(state);
}
return state;
}
public void highlight(mxCellState state)
{
if (validState != state)
{
Rectangle dirty = null;
if (validState != null)
{
validState.setStyle(lastStyle);
dirty = validState.getBoundingBox().getRectangle();
dirty.grow(4, 4);
}
if (state != null)
{
lastStyle = state.getStyle();
state.setStyle(new Hashtable<String, Object>(state.getStyle()));
state.getStyle().put("strokeColor", "#00ff00");
state.getStyle().put("fontColor", "#00ff00");
state.getStyle().put("strokeWidth", "3");
Rectangle tmp = state.getBoundingBox().getRectangle();
if (dirty != null)
{
dirty.add(tmp);
}
else
{
dirty = tmp;
}
dirty.grow(4, 4);
}
validState = state;
graphComponent.repaint(dirty);
}
}
public void reset()
{
highlight(null);
}
public void paint(Graphics g)
{
// do nothing
}
};
graphComponent.getConnectionHandler().setMarker(highlighter);
