Scrolling inside a JTable cell in Swing

Question

I have a table each cell contains a image. if the image size is more than row height, I have added JScrollPane. Now when I run the application, scroll is visible in each cell but I'm not able to scroll it.

How can I do it?

Below is the code I'm using to add scroll pane.

Any sample code will be appreciated.

     private final JTable table = new JTable(model)

    {

    @Override public Component prepareRenderer(TableCellRenderer tcr, int      row, int column) 

    {
         Component c = super.prepareRenderer(tcr, row, column);
         if(isRowSelected(row))              
         {
             c.setForeground(getSelectionForeground());
             c.setBackground(getSelectionBackground());             
         }             
       else{
             c.setForeground(getForeground());
             c.setBackground((row%2==0)?evenColor:getBackground());
         }
         JScrollPane _pane=new JScrollPane(c);
         table.setRowHeight(100);
         return _pane;
     }
};

Seems like the making of an unusable GUI, when you expect the user to scroll in order to see the content of table cells. — Andrew Thompson, Apr 01 '15 at 06:03

Right click on your jscrollpane
Properties
HOrizontal scrollbarpolicy = always
Vertical scrollbarpolicy = always

To be able to scroll Right Click on Jtable Autocreatecolumnfrommodel =false(deactivaded)

maybe you dont need to scroll, you need change the height of every row with the mouse – Isbelmont Apr 01 '15 at 06:33
When you have lot of data you will see the scroll bar – Isbelmont Feb 20 '16 at 14:17

In order to be able to set the focus on the cell (so you can use the inside scroll pane), you can get it through "edit mode":

Create a custom cell editor:

     public class MyCustomCellEditor extends AbstractCellEditor implements TableCellEditor{
     @Override
     public Component getTableCellEditorComponent(JTable table,Object value,boolean isSelected,int row,int column) {

                 JScrollPane your_custom_panel=new JScrollPane();
                 return your_custom_panel; // your _pane
     }

     @Override
     public Object getCellEditorValue() {
         return null;
     }

Set it on your table:

     table.setDefaultEditor(MyCustomCellValueType.class,new MyCustomCellEditor());

Now you only need to manage how to enter in "edit mode" and you should be able to scroll inside the cell.
