示例1: getCursorPos
/**
* Returns the current position of the cursor.
* @param nLine Holds the line on which the cursor is currently located
* @param nCol Holds the column on which the cursor is currently located
* @return true if successful, false otherwise (cursor interface was not
* obtained)

}示例2: getWordUnderCursor
