Add several small jtables into jframe

Question

Hi,
I am trying to implement a GUI where a desired number of small tables can be added into a frame when the user clicks the menu item "new module" in the menu. So far, I can just add one table. For that, I have implemented an action listener. The table is created in a method called createTable().
Here is the code fragment:
ActionListener editListener = new ActionListener() {
                              public void actionPerformed(ActionEvent editEvent) {
                                   if (editEvent.getActionCommand().equalsIgnoreCase("New Module"))
                                        //event1.getActionCommand();     
                                        //Container frame = new Container();
                                        createTable();
                                        tablearea.add(jTable1);
                                        repaint();                                   }...}
                         };Does anyone have an idea how I could implement the functionality that when the user clicks the menu item several times, new tables are painted in the frame differing in their positions (e.g. next to each other).

Answer 1

a) you need a LayoutManager in your tablearea-Panel. Maybe GridLayout is what you need or the more complex GridBagLayout. However, the BoxLayout is a look worth too!
b) depending on the LayoutManager you use, you have to do a little more than just to 'add' the table - depending on the Manager. GridBagLayout (for instance) need a configured GridBagConstraints-Object.
c) try tablearea.validate() or tablearea.invalidate() to repaint the content (look javadoc about both methods).
