在单个列中组织JButton？

Question

I've never really looked into layouts before, and it seems very confusing to me with all the choices given. What I'm trying to do is position buttons in one column down the centre of my JPanel (and maybe in one place have 2 buttons in one row). My question is; which layout manager should I use?

Answer 1

What about BoxLayout with vertical orientation or GridLayout with one column and multiple rows?

To have 2 buttons in one row place a sub panel with the 2 buttons the same way as simple buttons.

Answer 2

You can do it with just a BoxLayout, then centring the components inside the layout.

pnlMain.setLayout(new BoxLayout(pnlMain, BoxLayout.Y_AXIS)); //Creates the layout

And then in a component's class:

this.setAlignmentX(Component.CENTER_ALIGNMENT); //Centres the button
