When you create your sliders you assign them to local variables with the same name as your member variables; leave out those local variables because they hide your member variables.

You don't create rLabel, gLabel and bLabel but you do want to assign a text to them in your change listener. They are still null so a NullPointerException is thrown.

There may be more errors but I suggest you sprinkle in some System.out.println() statements here and there so you can see what is actually happening.

kind regards,

Jos

Have you read the API documentation for the JSlider component? You can programmatically set its position.

ya I have read it..I am just a litle lost in where to go from here. I want to be able to click say my red square and then have the 3 sliders at the bottom jump to the position they need to be in to make red. so when red has been clicked the red slider will be at 255 the green at 0 and the blue at 0..and so on..

Well, as Jos said, the documentation holds all the answers you need. JSlider::setValue().

ok I understand the set value. here is my problem though.. if i add the following code "RedS.setValue(255);" down in my mouse listener class well then if i click any of the 16 colors in my grid then the red slider changes to the value of 255. I want to be able to click just the red button and have the value change to 255 and if i click the blue button then the red goes to 0 and the blue goes to 255 and so on. So my question is how do i set it up to change based on my 16 different color squares. each color square in the grid is created as an array like so..

"colorArray[1]=RED;"

hopefully this makes sense..some guidence on how to fix this problem would be great. thanks.

If you have a Color object you can get its color components with the getRed(), getGreen() and getBlue() methods. Again, first read the API documentation and then post a question if you can't find what you're looking for.

i have read the api on it. But I think what i want to know how to do or where to look at how to do is inside my mouse listenter be able to say
"if mouse event e = colorArray[1]
then update slider to correct position"

im just confused on the proper syntax on how to code something like that.

@yeshello54
Did you write the code yourself? Because in your GridCellHandler you already do have usable code.

ahhh i figured it out now. Thanks for the direction. yes actually we wrote that method in class so that everyone could use it. I think i was thinking to hard about how to get the background color..thanks for the help
