This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Hey Ranchers-- I have a few questions: 1.) OK, everybody asks how you can access the local file system from an applet. I've seen this asked it seems like hundreds of times. It seems clear you can't do this in an applet unless the applet is signed or you are using appletviewer and you specify security settings blah blah blah. But, I've seen it done in several places on the web. So, I guess they're not using Java, but how exactly are they doing it? 2.) I want to be able to have a drop down box (I have been using Choice), but I want the user to to be able to select multiple items. I tried using CheckboxMenuItem but I think that can only be used with Frames. I tried a PopupMenu with a TextField and I could make it all work but everytime I show() it has the same name as the parent on all the items in the PopupMenu no matter what I do. That or it doesn't show the any names. Is there a way I can accomplish this. A snippet of code would make you my best friend because I have seen several descriptions but can't make them work and I have spent several, several hours on it. 3.) I want a dropdown menu like a choice but I want the choices to be little icons or pictures or whatever. I can't see any way to do this but know it's possible. I can't use swing because it's an applet and I want it to work on a webpage without requiring the user have the plugin. P.S. In case it wasn't clear, I don't want the user to use swing OR have it just be functional in appletviewer because I want to actually deploy this on a webpage. Responses will be rgeatly appreciated and in fact I will spend several minutes thinking really good thoughts about anybody who replies. Hey, who couldn't use a little extra good karma?
Hi Matt! In order of your questions: (1) I'm not sure how they are doing it. Do you have an example of a site which does this? (2) Here is a sample code which does what you asked (shows a popup menu in which the user can select multiple items at the same time):
(3) I haven't tried to show images like you describe without using Swing, but this person had a similar question about showing an image on a button without using Swing, so maybe it will help you: http://www.javaranch.com/ubb/Forum2/HTML/000865.html I hope this helps. (Please let me know if I have qualified to become your new best friend and receive several minutes of good thoughts/good karma).

Stephanie, Most assuredly! You should be feeling the warm glow of good thoughts right about....NOW! They should continue for quite sometime. My Thoughts: "Stephanie is nice, Stephanie is kind, Stephanie is good, Stephanie is nice, Stephanie is kind, Stephanie is good, ..."
With Respect, Matt P.S. Oh yeah, since your my best friend now, it might be a good idea for you to take up beer drinking.
My answer is to question #2: You can use JList object to display a serie of item, and allow the user to select multiple choices. listboxname.MULTIPLE_INTERVAL_SELECTION. Hope i can help more.

Thanks Mindy, but, as I said, I don't want to have to use Swing as I want to deploy it on the web and I don't want users to have to have the plugin. But thanks just the same. With Respect, Matt DeLacey
