Question

I created a JTable in a JScrollPane , but its not showing in the program.

Here is my code:

        scrollPaneTable = new JScrollPane();
        scrollPaneTable.setBounds(10, 507, 854, -480);
        
        table = new JTable();
        table.setForeground(Color.BLACK);
        table.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
        table.setCellSelectionEnabled(true);
        table.setFillsViewportHeight(true);
        table.setBackground(Color.LIGHT_GRAY);
        table.setBorder(new EtchedBorder(EtchedBorder.RAISED, Color.GRAY, null));
        table.setModel(new DefaultTableModel(
            new Object[][] {
                {"PC", "Computer", "Dominik", "Test", "Test"},
            },
            new String[] {
                "Name", "Beschreibung", "Nutzer", "Ort", "Seriennummer"
            }
        ));
        table.setColumnSelectionAllowed(true);
        table.setVisible(true);
        scrollPaneTable.setViewportView(table);
        jFW.getContentPane().add(scrollPaneTable);

Answer 1

You don't have a main method, you initialize UI and create JTable etc. in the Constructor of Gui class.

You need to create new Gui object in main to see Frame Table etc. (Not neccesarily inside the Gui class)
