I have a question :
i was studying the mvc architecture of swings and saw that when it comes to JButton we never call the model to change the contents(such as actionCommand) instead we call the setActionCommand()
and in the source code i saw that it looks something like this :
now whenever we deal with Jslider or JTables then we always do changes in the model by calling the models and explicitly do changes in the model . We could have come up with similar code for sliders as well ? Why didn't we ?
You are right that JTable has no methods for adding rows. That's because the TableModel interface doesn't require implementing classes to support it; you could have an implementation with a fixed number of rows and columns. Changing the value of a cell is possible through the JTable though.
