Bug Description

using openjdk 6b12-0ubuntu6

running netbeans 6.1, there are some problems with graphic. Maybe the problem is in rendering fonts.
Everything is bigger in comparison to sun java.
Even the UML editor has the same text problems for labels: the label text is not inside the field, as it should be, but under it.

The java.awt.font.TextLayout.getBounds() method returns a box that is shifted upwards compared to the box that is returned by Sun's official JRE.

Sample code:
package swingbug;

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Rectangle;
import java.awt.font.FontRenderContext;
import java.awt.font.TextLayout;
import java.awt.geom.Rectangle2D;

import javax.swing.JFrame;

public class SwingBug extends JFrame {

private static final long serialVersionUID = 1L;

public static void main(String[] args) {
  new SwingBug().setVisible(true);
}
public SwingBug() {
  setTitle("Swing bug");
  setSize(400, 400);
  repaint();
}
@Override
public void paint(Graphics g) {
  Graphics2D graphics=(Graphics2D) g;
  graphics.setColor(Color.BLUE);
  graphics.fillRect(0,0,400,400);
  drawString(graphics, "Hello Kitty!", 100, 100);
}

public void drawString(
   Graphics2D graphics, String string, int x, int y) {
  if (string.length() > 0) {
   Font f = new Font("times", 0, 16);
   graphics.setFont(f);
   FontRenderContext fontRendererContext = new FontRenderContext(null, true, true);
   TextLayout textLayout = new TextLayout(string, f, fontRendererContext);
   Rectangle2D rectangleOfText=textLayout.getBounds();
   Rectangle backgroundRectangle=rectangleOfText.getBounds();
   graphics.setColor(new Color(1.0f,1.0f,1.0f,0.5f));
   graphics.fillRect(backgroundRectangle.x+x,backgroundRectangle.y+y,backgroundRectangle.width,backgroundRectangle.height);
   graphics.setColor(new Color(0,0,0));
   textLayout.draw(graphics, x, y);
  }
}
}

With Compiz activated the result is getting more weird

The "dust" on the picture appears when I run the test code with compiz activated. It is not deterministic but is always different on each run of the code. The "extra" white rectangle is always the same.

It seems to be video driver problem but other (non Java) programs on the desktop all work fine and are not affected.

I'm no 2-d expert, but these appear to be the same bug:

swing TextLayout.getBounds() returns shifted bounds

those returned by Sun JDK

openjdk-6 uses the system font by default. I don't think this is a bug in openjdk-6 itself. can netbeans be made aware of different font sizes?

What do you mean when you say "it uses the system fonts"? What does
sun-java use instead?

I tried to change the application system font, from the apparence
applet, but the font did not change in netbeans.
Anyway it's not only that the font is bigger, but as you can see in
the screenshots, the spacing is huge.

From netbeans I can only change the syntax font, not the menu font.

Marek Slama (mslama-email) wrote on 2008-10-27:

Yes it is possible to change only editor font from inside NetBeans IDE. The rest (menu, tree, tab, ...) use default Swing font. Yes I can see spacing is bigger on openjdk. I will check default Swing component as IMO it is not specific to NetBeans. Note that it is Metal L&F.

I think we should mark this Invalid for netbeans.
However, I've been bitten by this in the stuff I run with openjdk, the menubars specifically are taller than they should be.
In my opinion there is a significant departure in the look of java apps with openjdk, I would investigate if something can be done to attenuate that difference.

The gtk look and feel is ok, but it's really slower on my machine. And
anyway the labels in the UML editor are placed in a different position
that the text contained

I have tried (from my amateur status) to implement all suggestions here, but the Netbeans IDE font spacing is still too big. I did the whole Ubuntu installation in the last couple of days. I can't agree that this is low priority. Netbeans is currently unusable for serious development. Is there an answer to Michael's question - is the a package I missd during the installation?

Run the attached test program, with and without LANG set to see the difference. Removing all of gujarati,hindi,punjabi,tamil does fix the problem. why did we add the sequence.allfonts.UTF-8 sequence at all?

is there something to fix in these fonts?

Matthias,

This bug is not related to ttf-indic-fonts

It must be related to rendering engine used in OpenJDK. Can anyone
check the rendering engine
ttf-indic-fonts work well with current versions of pango, QT & ICU
without any problems. so it must be an issue with rendering engine
used in netbeans

I found a solution to this bug here

just need to edit
  /etc/java-6-openjdk/fontconfig.properties
and change the line
  sequence.allfonts.UTF-8=latin-1,wqy-zenhei,japanese-vlgothic,japanese-kochi,japanese-sazanami,korean-un,korean-baekmuk,bengali,oriya,telugu
to
  sequence.allfonts.UTF-8=latin-1,wqy-zenhei,japanese-vlgothic,japanese-kochi,japanese-sazanami,korean-un,korean-baekmuk

This worked for me in Jaunty x86_64.

Using jaunty 9.04 x86. After installing Netbeans, experienced the same issue: free space under text in different situations. The program code looked bad, if opened in NetBeans editor.

The workaround, suggested by Carlos Ramos, has worked for me! (My first language is Russian, so deleting these fonts from the list did not affect me)

Nevertheless, the bug stays unfixed...

The same here - suggestion made by Carlos Ramos fixed this problem for me - using Jaunty x86_64. Otherwise using openjdk after clean install makes it almost unusable (in my case with ImageJ). Bug isn't fixed.
