Centering

[Richard West]

Hi everyone,

I am trying to center a page number on the bottom center on a printed page but i am having some trouble doing it.

I am using the windows default page dialog where the user can select the desired page size(ie, a1,a2,a4) but i am unable to center the page number on the bottom center.

For now i am using hard-coded values but these values only work for the a4 paper format.

 
public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) 
{
//other codes
//other codes
 
Font f = new Font("Arial", Font.PLAIN, 12);
graphics2D = (Graphics2D) graphics;
graphics2D.setFont(f);
 
graphics2D.drawString(("Page " + (pageIndex + 1)), 223, 643);
 
}
 

I know centering the page number involves the FontMetrics class but i can't seem to get it right. What i would like is for the user to select any page format using the windows page dialog and the page number is drawn on the bottom center of the page when it is printed

I hope someone can help me with this problem

Thank You

Yours Sincerely

Richard West

Hello Richard,

Try this :

public int print(Graphics g, PageFormat pageFormat, int pageIndex) 
{
   String testString = "this is a test !";
   Font courierFont = new Font("Courier",Font.BOLD+Font.ITALIC,24);
   g.setFont(courierFont);
 
   // center the string
   FontMetrics m = g.getFontMetrics();
   int stringWidth = m.stringWidth(testString);
   int width = (bounds().width - stringWidth )/2;
   int height = bounds().height / 2;
 
   // draw the string
   g.setColor(Color.green);
   g.drawString(testString,width,height);
}

Hope that helps,

oops
That should center testString in the page but you may want to set height to bounds().height - x.

Regards,
