keep the size of a line even if the screen settings are change

[bumpert]

Hi, i have a weird things to do, and found nothing on google and others place...
For example, i draw a line of 1 inch into my computer where my resolution is 96dpi and my screen area is 1024x768
i need to made modification to this line to have a 1 inch line on every screen settings. example: my friend that are in 800x600 and have a dpi of 128 opn my program to see the line... i want him to see a 1 inch line too
so i need to find a way to do that so when i have the screen size and the screen resolution that i could have on the screen a 1 inch (example) line for every settings...
sorry for my english! can someone help me to find an idea...?
thx a lot

I came across a similar problem in that I had to find out the size of ALL monitors...including for a multiple monitor setup, so this should work all the same:

private Vector monitors = new Vector();
    private int numOfMon;
public void initMonitors() {
        monitors.clear();
        GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
        GraphicsDevice[] gd = ge.getScreenDevices();
        for (int i = 0; i<gd.length; i++) {
            GraphicsConfiguration[]  gc = gd[i].getConfigurations();
            for (int j = 0; j<gc.length; j++) {
                if (monitors.contains(gc[j].getBounds()) == false) {
                    
                    monitors.addElement(gc[j].getBounds());
                    
                }
            }
            
        }
        numOfMon = monitors.size();
    }
public int getNumOfMonitors() {
        return numOfMon;
    }
    
    public Rectangle getSizeOfMonitor(int numOfMonitor) {
        return (Rectangle)monitors.elementAt(numOfMonitor);
    }

Sorry if some of the variables and stuff are missing, but the rest of it should work. I left out the code to set which monitor you want a window on...hope this helps!
