Hello everyone, I'm fairly new to Swing, only coded 2 UIs so far (what a pain it was). Can someone show me a "small" code example of how a Controller interacts with the View? I'm trying to implement the MVC into my project. I think I have a pretty good idea on how the Model works, in that the Controller would simply call a method on the Model passing any parms. So, how is the View interacting with the Controller, passing events and data? Should there be a controller for every window and should the controller control every object within the window?
Any additional information you can provide is appreciated.
For an example of MVC, see reply 13 on this thread. To access the images now, replace the prefixstring (in the static block in ImageView) with this

Hi Craig, Thanks for replying back. I made the modification as you requested and then ran the App and received the following error:

Any idea why I'm getting this error?

Ouch. That doesn't look like fun. This has come up with certain video cards in the recent past. You might try searching the forums at Sun; I remember seeing an informative thread a while back. Have you had similar difficulties with other image and/or animation apps? You can find some in this forum and at Sun, especially their Java2D forum.

Thanks Craig, I'll see what I can figure out.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
