#1432 — Drawing icons on a scroll

  To: comp.lang.java.gui
Ok,

    I have a friend who is doing a simple Java Swing project.  I don't know 
from Java, but I am an experienced programmer in other languages, so I am 
trying to help him.

    He's got a JScrollPane with an image in it.  He wants to be able to put 
an icon on the JScrollPane in response to user input.  He needs the icon 
redrawing to be handled by the JScrollPane, i.e. the JScrollPane should tell 
the icon when it needs to redraw itself.  He'll also need to be able to 
delete the icon, of course.  What's the "correct" way to do this in Swing? 
Can anyone give me a quick & simple explanation?

Thanks,
Tom

Tell 'your friend' that one easy way to achieve this in
Java is to put a JPanel with an appropriate layout in
the JScrollPane, then add JLabels (containing the images)
into the JSP as needed.  

A call to 'validate()' should have everything appear correctly.
