Method Details
-
getLevel
public int getLevel()Get the current heading level.- Returns:
- The heading level, as defined by one of this class' constants.
-
setLevel
public void setLevel(int val) Set the heading level of this question. This is roughly equivalent to heading levels in HTML, where heading 1 is the largest, for a document title or chapter. As the number grows, the heading is semantically finer grained.For compatibility purposes a question has heading level zero by default, this is the JT Harness 3.x style of rendering. Level 1 is the strongest heading level in JT Harness 4.x and later. A "none" heading level is also available, meaning that a null question is requested, but has no more semantic importance than any other question.
- Parameters:
val
- One of the level constants defined in this class.- Throws:
IllegalArgumentException
- If the parameter is out of range.- Since:
- 4.0
