Question

我正在尝试将图像显示到JTable的第25列： - 为此我编写了以下代码： -

    jTable1.getColumnModel().getColumn(25).setCellRenderer(jTable1.getDefaultRenderer(ImageIcon.class));
  String query = "SELECT   name,type,supplier, department, manufacturer, model, serial_no, description, location, broker, dop, installation_date, expiring_date, retiring_date,warranty_info, icost, rcost, aarea, voltage, wattage, amperage, eline, capacity, plink, notes, adding_date, modification_date from assets where  company_code='" + ims.MainWindow.cc + "' and adding_date between '" + new java.sql.Date(df.parse(df.format(jXDatePicker1.getDate())).getTime()) + "' and '" + new java.sql.Date(df.parse(df.format(jXDatePicker2.getDate())).getTime()) + "'";
            System.out.println(query);
            ResultSet rs = st.executeQuery(query);
            int xx = 1;
             byte[] imagedata=null;
            ImageIcon format=null;
            java.awt.Image originalImage=null;
            java.awt.Image scaledImage=null;

            javax.swing.ImageIcon newIconImage=null;
            while (rs.next()) {
                if(rs.getBytes(24)!=null){
                imagedata=rs.getBytes(24);
                  format = new ImageIcon(imagedata);
                originalImage = format.getImage();
                scaledImage = originalImage.getScaledInstance(268, 200, java.awt.Image.SCALE_SMOOTH);
                newIconImage = new javax.swing.ImageIcon(scaledImage);
                }
                mod.addRow(new Object[]{xx, rs.getString(1), rs.getString(2), rs.getString(3), rs.getString(4), rs.getString(5), rs.getString(6), rs.getString(7), rs.getString(8), rs.getString(9), rs.getString(10), rs.getString(11), rs.getString(12), rs.getString(13), rs.getString(14), rs.getString(15), rs.getString(16), rs.getString(17), rs.getString(18), rs.getString(19), rs.getString(20), rs.getString(21), rs.getString(22), rs.getString(23), newIconImage, rs.getString(25), rs.getString(26), rs.getString(27)});
                xx++;
            }

当我运行包含以下代码的框架时，而不是在图像列中显示“javax.swing.ImageIcon@119537a”中的图标，而是显示在图像列中。请帮忙

Answer 1

您可以尝试更改设置图像图标渲染器的列号。我试试24 in

jTable1.getColumnModel().getColumn(25).setCellRenderer(jTable1.getDefaultRenderer(ImageIcon.class));

我怀疑渲染器没有针对添加图像图标的列进行更改。

Answer 2

当我运行包含以下代码的框架时，而不是显示图像列“javax.swing.ImageIcon@119537a”中的图标正在显示如图所示。

我认为必须为proper ColumnClass设置Icon/ImageIcons (in this case and only)
JTable knows Icon/ImageIcons data type in the ColumnClass，与String，Number，Boolean和e.i相同。

Answer 3

您可能想看看Rendering BufferedImage in JTable cell这是一个类似的问题。

Answer 4

我认为您需要将列号更改为24而不是25。

jTable1.getColumnModel().getColumn(24).setCellRenderer(jTable1.getDefaultRenderer(ImageIcon.class));

在JTable中显示图像
