Hour 20: Responding to User Events with Swing
NOTES AND CORRECTIONS
- You can try out a Java 1.02 version of
the LottoMadness applet on this site, and also run a souped-up
version called LottoRobics.
TextListener interface works for Java 1.02
and 1.1 text fields, but monitoring text changes in Swing requires
the use of the
DocumentListener interface and the
Document class. A new section is being prepared on
the use of this interface and will be published on the site so you
can complete the hour's second activity.
- The variable name
command is incorrect on Page 324, Line
137. The corrected line is the following:
Object item = event.getItem();
