JTable -background color

[francis varkey]

Dear Sir,

I create a JTable using DefaultTablemodel with initially zero row. table is added in a JscollPane table's row increase dynamically according to some events. I provide the size to table using setBounds(int,int,int,int) of JScrollPane. also provide the backgound color using SetBackground(Color) of JTable . Then I want to provide color the entire setBounds(int,int,int,int) area. how to do it? This is normaly fine in the case JButton,JCheckBox etc. But there is a problem in the case of JTable.

You are settings the bounds of the table or the scroll pane?

If the size of the table is smaller than the viewport, which
is extremely likely if the table has zero rows, then you are
seeing the the scrollpane's background.

I am setting bounds to Srollpane. but I see the background color as gray color. I am sure this is not the background color of Srollpane or the JPanel.
Becuase I am setting different background color to Srollpane and JPanel.

Can show us some code? Strip out only the frame/panel/layout/color stuff and let us take a look at it. Table too, but shouldn't need to see your TableModel.

[francis varkey]

panel.setLayout(null);
panel.setBackground(new Color(240,255,255));

String head[]={"City","Date","HotelName"};
model=new DefaultTableModel(head,0);
table=new JTable(model);
JScrollPane scroll=new JScrollPane(cart_hstable,v,h); // (v,h)Constants

scroll.setBounds(20,30,950,280);

panel.add(scroll);

Try getContentPane().setBackground(Color). I've found that will fill in the areas that just using setBackground(Color) sometimes doesn't.

As I said before, it's not the table's background you are seeing,
but the scroll pane's. Or to be more precise, the background of
the scroll pane's viewport. You'll get the effect you want with
scroll.getViewport().setBackground(Color.pink), or probably
use a color you like better than pink.

btw, is there a reason you are setting the layout manager to null
and calling setBounds? This has nothing to do with your background
color problem, of course, but I'd prefer something like this

panel.setLayout(new BorderLayout());
panel.setBackground(new Color(240,255,255));
 
String head[]={"City","Date","HotelName"};
TableModel model=new DefaultTableModel(head,0);
JTable table=new JTable(model);
JScrollPane scroll=new JScrollPane(table);
 
panel.setBorder(BorderFactory.createEmptyBorder(30, 20, 30, 20));
panel.setPreferredSize(new Dimension(990, 340));
 
panel.add(scroll, BorderLayout.CENTER);
