CHECK BOX not coming in TABLE : VERY URGENT
Hi all,
Please help me.. I created a table with four clooumns. everything is working fine , but problem is in lat column I want to show CheckBox.. But it is printing "java.lang.object@4121f" like values.
I also implemented method
public Class getColumnClass(int c)
{
return getValueAt(0, c).getClass();
}
i my TableModel. I am attaching whole code here.. please run it and see what is the problem ..
plaesae its URGENT as I already wasted so much time on this and now project deadline is too near..
here is code :
