I want to tell how wide a string (say "abcde") would be in pixels using a particular font.
Is it possible to do this?

public void paint( Graphics p )
{
  Font f = new Font( "Helvetica", Font.BOLD, 12 ) ;
  g.setFont( f ) ;
  FontMetrics fm = getFontMetrics( f ) ;
  int width = fm.stringWidth( "abcde" ) ;
}

should do it...(for an applet)

Good Luck!!

Obviously, if you havent set a font, then you can do:

public void paint( Graphics p )
{
 FontMetrics fm = getFontMetrics( getFont() ) ;
 int width = fm.stringWidth( "abcde" ) ;
}

You can also call getFontMetrics() from any component (Frame, JFrame, JPanel, etc) if you are writing an app...

Good Luck again!!
