slider help required(java)

empirix

Lads/Lassies,

I'm in need of some quick help. Basically i have to hand in a final assignment within 5 hours and i am stuck on one thing.

Basically I need to implement a button in the bottom left hand corner(like windows), and then have a slider adjacent to it(like windows except the taskbar is a slider).

Now i implemented the button and it basically was the length of the whole "taskbar", then i implemented the slider and this overwrote the button and now the slider is the whole length of the "taskbar".

Please find the code below and if anybody can tell me what i have done wrong\left out ,it would be very much appreciated.




public static final int FrameWidth = 500;
public static final int FrameHeight = 300;

private int angle = 45;
private String message = "Angle: " + angle;
private PinBall PinBall = null;
private Scrollbar slider = null;


public static void main( String[] args ) {
PinWorld cw = new PinWorld();
cw.setSize(FrameWidth, FrameHeight);
cw.show();
}


PinWorld()
{
setLayout(new BorderLayout());

Button fire = new Button("fire");
fire.addActionListener(new FireButtonListener());
add ("South", fire);

slider = new Scrollbar(Scrollbar.HORIZONTAL, angle, 5, 0, 90);
slider.addAdjustmentListener(new PinSliderListener());
add ("South", slider);
pack();

slider = new Scrollbar(Scrollbar.VERTICAL, angle, 5, 0, 90);
slider.addAdjustmentListener(new PinSliderListener());
add ("West", slider);
pack();
}


private class FireButtonListener implements ActionListener
{
public void actionPerformed (ActionEvent e)
{
double radianAngle = angle * Math.PI / 180.0;
double sinAngle = Math.sin(radianAngle);
double cosAngle = Math.cos(radianAngle);



I should add that the 'Vertical' Slider is for controlling the angle/direction of the ball and the 'horizontal' slider is for controlling the power/force behind the released ball.
Its the horizontalslider/button thats causing me problems.

Again any help appreciated

If the problem is just that they are "overwriting" each other on the screen the change the layout and put them in a grid layout or some such. Also might help to add them to their own JPanels and then put them in the main frame.

yeah, you are just adding them south.

Set up a grid layout then add them at the co-ords

so psuedo code would be

add(button, 2,1)
add(slider 2,2)

sorry I cant write the actual code but Im swamped in work at the minute
