Display JComboBox in a JTable

ttelloow — Thu, 10 Sep 2009 11:16:33 -0400

Help!!
I've managed to get a JComboBox into a single cell in a JTable
but it is not visible as a JComboBox unless the user actually
clicks on it.
I'm assuming it is possible to make this component visible..
Thanks in advance

New comer comes calling-implemeting/creating a method(specifics)

oya_oya — Sat, 16 May 2009 12:20:43 -0400

okay, I a m very new to Java and not so great at it, though I don't think I'm that bad either,

Anyway, I have to implement a method in a clock class. Every time I try to figure a way to implement the elapsedTime method I get an error message--"inner classes cannot have static declarations"--or--"Cannot find symbol: method timeElapsed(Clock, Clock) location: class TC". when I create a class TC I get the error, "inner classes cannot have static declarations" when I remove static from my timeElapsed method the error is "non-static method cannot be referenced from static context".
