JProgressBar look ?

Thread view:

FET - 22 Jul 2004 10:02 GMT

Hello everyone,
I am trying to get a particular look of the JProgressBar for my Splash
screen. This JProgressBar should display a bar from left to right
(normal), but it shoulnd't be a continuous bar, it should be like a
dashed bar. How do I get that effect in Java ?

Thanks in advance.

Best regards.

you should override paintComponent and use appropriate Stroke to draw
progress line.

for example:

Stroke myStroke = new BasicStroke(lineWidth, cap, join, miterlimit, dash,
dashPhase);

public void paintComponent(Graphics g) {
//may be super.paintComponent();
Graphics2D g2d = (Graphics2D)g;
Stroke save = g2D.getStroke();
g2D.setStroke(myStroke);
g2D.drawLine(....) ;
g2D.setStroke(save);
....
//and so on
}

Hi there,
Thanks for the prompt response, but I am not very familiar with
Graphics2D. Can you please tell me do I calculate the co-ords for the
drawLine method since these are supposed to vary and increase with the
ProgressBar's setValue(int) method ?
Thanks in advance.

Best regards.

Source is your best friend - look first how it was made in original, then
make your own.

Oh, right.. rIIIght, yes.

That *would* help to link to the source
to which you were referring. But I
thought that made it *too* easy.

Hey Guys,
That link was simply awesome. All I needed to do in my code was

UIManager.put("ProgressBar.cellLength",new Integer(10));
UIManager.put("ProgressBar.cellSpacing",new Integer(3));

That gives me the dashed pattern of the JProgressBar.

Thanks a lot for all your help!

I just wonder why they didn't put methods setCellLength() and
setCellSpacing() in JProgressBar
