How to create a copy of a JTable with same model, color, font and listeners?

I am making a program in which I need to use many JTables. So I need to clone a JTable many times. By cloning I mean a copy with same model, same columnModel, same font size, same color etc.

I have found how to clone a jtable.

But the problem is only the text of the both is same. Not the font or colors.

I also tried this:-

JTable  t1 = new JTable(tm.getTable().getModel(), tm.getTable().getColumnModel());

But this is also not working.

I also tried:-

JTable ti = tm;

But this will work. But the problem is changes made to tm will also happen with ti.

Is there any way to clone a jtable with all its properties?

Solution

  • Do this:

    JTable  t1 = new JTable(tm.getTable().getModel(), tm.getTable().getColumnModel());

    And then, take every relevant attribute that the first table has, and assign it to your second table.

    For example:

    t1.setFont(tm.getFont());
// And so on

    OR

    You can always deep clone the object through serializing. Check this article for more. It may be an overkill, but that is for you to decide.
