java jtable

[samona]

I need some help printing a jtable so that the table prints 50% of what the normal print size would be.  Any ideas on how I can control the Jtable's print size?

You set it in the cellrenderer.  There are a few ways to do this depending on how you're building your table.  Show us your code.

If you want to change the font for every cell you can simply set the font directly to your table:

            final JTable table = new JTable(data, columnNames);
            table.setFont(new Font("Serif", Font.BOLD, 20));

thank you for the response.  below is my cell renderer.  I can only make the size of the data but not the actual table which what I want.

 

public class MyTableCellRenderer extends javax.swing.JLabel implements
        javax.swing.table.TableCellRenderer {
    
    
  
  
    
    public java.awt.Component getTableCellRendererComponent(
            javax.swing.JTable table, java.lang.Object value,
            boolean isSelected, boolean hasFocus, int rowIndex, int colIndex) {
        
        setText(value.toString());
        
        if (value.equals(null)) {
            
            return this;
        }
            javax.swing.JLabel label = new javax.swing.JLabel(value.toString());
            //label.setFont(new java.awt.Font("Helvetica Bold", java.awt.Font.PLAIN,7));
            label.setVerticalAlignment(javax.swing.SwingConstants.CENTER);
            label.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
           // System.out.println("IN RENDER");
     
        return label;
        
        
    }
    
    public void validate() {}
    public void revalidate() {}
    protected void firePropertyChange(String propertyName, Object oldValue, Object newValue) {}
    public void firePropertyChange(String propertyName, boolean oldValue, boolean newValue) {}

Instead of statically calling these packages just import them at the top.

That's a bit ambiguous, what part of the table do you want to increase the size to?  Padding, height, width, overall table size, what?

Have you looked at the documentation? - http://docs.oracle.com/javase/1.5.0/docs/api/javax/swing/JTable.html

I want to change the actual table width and height to be smaller for printing purposes.  I want the table as a whole to be smaller.  Right now for printing I have  FIT_WIDTH which span across the whole page, but I want the table width to span only across half the page. 

 

I looked at the link before, but nothing jumps at me as to adjusting overall table size for printing.

I guess you could grab the screen size and just divide by 2 when you set the table size.  Try:

        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        table.setSize(screenSize.width / 2, screenSize.height / 2);

That made no difference.  What I ended up doing is setting the column size.  I can't make out the table's data on the screen now, but at least it prints the way i want it.  However, it would be nice if I could adjust the print size without affecting the window on the screen.
