Hi, I'm trying to create a "tiling" application.

I have a JPanel with a grid layout. Currently it has 3 rows and 3
columns.

I put a jlabel into each "cell". The jlabel is set to be 50 high by 50
wide.

When however I put this Jlabel into the Jscrollpane , my prefered size
for
the Jlabels is ignored and the grow so that the Jpanel fills the entire

Scrollpane viewport!

How do i get it so that this does not happen. I want my Jlabels to stay
the
size i want, and to be bunched up in the top left corner of the
Jscrollpane.

Any ideas??

P.S.  I also want to dynamically resize this JPanel, and if it is
larger
than the scrollpanes viewport obviously I want it to scroll. This part
I'm
pretty sure I know how to do (delete the old Jpanel then create a new
of the
appropriate number of rows/cols, then add it to the Jscollpane).

Here is the code for the JPanel derived component (if you look you will
see
that i actually add the MapPanel component to a vanilla Jpanle with a
gridbad layout. This was an attempt to solve the problem, but only half

worked - i could get the right size vertically or horizontally but not
both)
----------------------------------------

public class MapPanel
    extends JPanel {
  int rows = 3;
  int columns = 3;
  GridLayout gridLayout1 = new GridLayout();

  public MapPanel() {
    try {
      jbInit();
    }
    catch (Exception exception) {
      exception.printStackTrace();
    }
  }

  private void jbInit() throws Exception {
    this.setLayout(gridLayout1);
    gridLayout1.setColumns(columns);
    gridLayout1.setRows(rows);
    for (int row=0; row<rows; row++)
      for (int column=0; column<columns; column++)
      {
        JLabel tempJLabel = new JLabel(Integer.toString(row));
        tempJLabel.setBorder(BorderFactory.createEtchedBorder());
        tempJLabel.setMaximumSize(new Dimension(50, 50));
        tempJLabel.setMinimumSize(new Dimension(50, 50));
        tempJLabel.setPreferredSize(new Dimension(50, 50));
        this.add(tempJLabel);
     }
    this.setMaximumSize(new Dimension(rows * 50, columns * 50));
    this.setMinimumSize(new Dimension(rows * 50, columns * 50));
    this.setPreferredSize(new Dimension(rows * 50, columns * 50));

  }

}

Here is where I add it to the scrollpane


  JScrollPane jScrollPane1 = new JScrollPane();
  JPanel SuperMapPanel = new JPanel();
  GridLayout gridLayout1 = new GridLayout();

    jScrollPane1.setHorizontalScrollBarPolicy(JScrollPane.
HORIZONTAL_SCROLLBAR_AS_NEEDED);

jScrollPane1.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED);
    jScrollPane1.setBorder(BorderFactory.createEtchedBorder());
    jScrollPane1.setPreferredSize(new Dimension(600, 480));
    SuperMapPanel.setLayout(gridLayout1);
    gridLayout1.setColumns(2);
    gridLayout1.setRows(2);
    SuperMapPanel.add(new MapPanel());//djw hand added code
    jScrollPane1.getViewport().add(SuperMapPanel);
