[java] Grid layout

If you're using .net 2.0, I recommend using the TableLayoutPanel control for the general layout.

It adds RowSpan and ColSpan properties to it's child controls, so you can position the contained stuff across multiple cells like in HTML.

Ok, I have solved this.
I simply created another JPanel and added it to the main GridLayout, and set the sub panel to have a gridLayout as well.

I have a problem with the buttons and the JTableHeader.
They both appear very tall, how do I change their height?
Here is the code:

            super.setLayout(new GridLayout (3, 1));            ButtonsPanel.setLayout(new GridLayout (1, 3));            initUsersTable();            JTableHeader tableHed;            tableHed = m_table.getTableHeader();             tableHed.reshape(tableHed.getX(),                                              tableHed.getY(),                                             tableHed.getWidth(),                                             20);            super.add(tableHed);            super.add(m_table);            super.add(ButtonsPanel);            ButtonsPanel.add(new JButton("Add"));            ButtonsPanel.add(new JButton("Remove"));            ButtonsPanel.add(new JButton("Edit"));            m_window = new JFrame("Administrator");            m_window.getContentPane().add(this);            // TODO: Change on exit! write file!            m_window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);            m_window.pack();            m_window.setVisible(true);        }        private JComponent initUsersTable ()        {            String[] colNames = {"Name", "Password", "Type"};            String[][] data=null;            String[] KeysList;                        KeysList = m_userDatabase.GetKeysList();            KeysList = new String[10];            data = new String[KeysList.length][3];            for (int i=0; i<KeysList.length; i++)            {                data[0] = KeysList;                data[1] = KeysList;                data[2] = KeysList;            }            m_table = new JTable(data, colNames);                        return m_table;        }

I have another question.
I have a map object.
I entered objects to the map with the key being a string.
I want to get a String[] array containing all the keys in the map.
How would I do that?
I tried this:

        public String[] GetKeysList()        {            HashSet KeySet = null;                        KeySet = (HashSet)m_usersList.keySet();            return (String[])KeySet.toArray();                    }

But I got runtime error on: KeySet = (HashSet)m_usersList.keySet();
