setPixel()

How to use setPixel() in java

These are the only methods i could find. Im not sure if these are what you are looking for.

setPixel(int x, int y, int[] iArray, DataBuffer data)
Sets a pixel in the DataBuffer using an int array of samples for input.

setPixels(int x, int y, int w, int h, int[] iArray, DataBuffer data)
Sets all samples for a rectangle of pixels from an int array containing one sample per array element.

I want to draw in form when I mouse move?

just like in c++

setPixel(devicecontext,x,y)

i think you just paint a rectactle with a hieght and width of 1

Code:

---

Graphics g;
g.drawRectangle (x,y,1,1);

---

you can get x and y from your mouse move event listener
