I was hoping someone could help me out with something simple in Java. I'm trying to create a paint program using java.awt & java.swing. I have this program loading up a jpg and creating a paint layer over it that I can draw on. I'm trying to implement an RGB color picker consisting of 3 sliders (Yes I know there is a built in color picker but I need to implement it with the 3 RGB sliders). I created a seperate class called color pick that contrains the 3 sliders and my main class is instantiating this. What I don't know is how to make the main file get the color from this other colorpick class. The drawing is using a class called myPrimitive which at the moment is just a rectangle and the color is passed in through there. My code is here:

if anyone could help I'd greatly appreciate it!!!

TIA

How soon do you need this done by? I can take a look but I'm booked up for at least a couple of days.

java seems to be pretty hard for me at the moment too, maybe its because my teacher doesnt teach anything and he just gives us random programs. We have a program right now that needs stuff from chapter 5 in the book to work but it also needs stuff from 3 and 4, great. why cant he just go in....order!?!?!?

good luck with the coding memo

Graphics programming is really hard! I kinda did some po-drunk coding to get the color to work but now I have to implement a tinting brush which I have no idea how to do!

Do you know Java already, or are you just learning? If you're just learning, you might want to start with some command-line programming just to learn the language. If you're just learning, here's a good book: http://www.mindview.net/Books/TIJ/ You can actually download the whole thing from his website.

Are you just trying to get a hex string? Take a look here:

There's a lot of useful functions in that.
