示例1: getChildViewBounds
import javax.swing.text.View; //導入方法依賴的package包/類
/**
* Returns the bounds of a child view as a rectangle, since
* <code>View</code>s tend to use <code>Shape</code>.
*
* @param parent The parent view of the child whose bounds we're getting.
* @param line The index of the child view.
* @param editorRect Returned from the text area's
* <code>getVisibleEditorRect</code> method.
* @return The child view's bounds.
