Good morning/afternoon/evening,

I have a problem with painting some dots, First off, the dots placing
information gets read from a file, and directly painted onto a canvas
which resides in a scrollpane.

The problem is, that after I initiated the read+paint that the graphics
just wont stay on the canvas when i move other windows over it.

The current structure is something like this:
I have 2 classes, 1 visual which contains a scrollpane, this scrollpane
contains the canvas of class 2, lets call the classes Visual and
ReadPaint for easy reference.

In the Visual class I do the following in the actionperformed:

ReadPaint RP = new ReadPaint();
g = RP.getGraphics;
RP.paintComponent(g);

And in ReadPaint:

paintComponent(Graphics g) {
graphics 2D g2d = (Graphics) g;

something = file.readByte()

dot = new Line2D (x1, x2, y1, y2); // values depend on whatever is read
from the file

g2d.setColor(something)
g2d.draw(dot)

}

Some more detailed information would be verry much appreciated on
whether im using the graphics wrong, painting on the wrong component
and what i could try to fix it. (remember the data that it gets fed is
from a file, so no pre determined value of "something" )

Greetings, DC
