示例1: viewToModel
import javax.swing.text.View; //導入方法依賴的package包/類
/**
* Provides a mapping from the view coordinate space to the logical
* coordinate space of the model. The biasReturn argument will be
* filled in to indicate that the point given is closer to the next
* character in the model or the previous character in the model.
* <p>
* This is expected to be called by the GUI thread, holding a
* read-lock on the associated model. It is implemented to
* locate the child view and determine it's allocation with a
* lock on the ChildLocator object, and to call viewToModel
* on the child view with a lock on the ViewLayoutState object
* to avoid interaction with the layout thread.
*
* @param x the X coordinate >= 0
* @param y the Y coordinate >= 0
* @param a the allocated region to render into
* @return the location within the model that best represents the
* given point in the view >= 0. The biasReturn argument will be
* filled in to indicate that the point given is closer to the next
* character in the model or the previous character in the model.
