Description copied from interface: PenOwner

getPenClip

public final PenClip getPenClip()

Returns:

The PenClip associated with this PenOwner.

pause

protected final void pause()

draggingOutDisengaged

protected void draggingOutDisengaged()

Specified by:

draggingOutDisengaged in class AbstractPenOwner

getPenSchedulerLock

protected java.lang.Object getPenSchedulerLock(java.awt.Component component)

Checks if the given Component holds the Component.getTreeLock() before actually getting and returning the PenOwner.PenManagerHandle.getPenSchedulerLock(). Prefer using this method instead of PenOwner.PenManagerHandle.getPenSchedulerLock() to be shure you aren't causing deadlocks because the ComponentPenClip methods hold the Component.getTreeLock().
