Well, to change the text on a Label, you just have to call
"label.setText(...);". The "business logic" in your first button just has to
keep track of how many times it has been pushed (i.e., which saying you want to
display next), and set the correct text each time.
I'm not sure exactly what you're trying to do with the second button.... Do you
just want it to make the label show up? In order to do that, just do:
BoxPane boxPane = .... // Or could be set using a @BXML annotation
Label label = new Label("initial saying");
boxPane.add(label);
The repaint should be taken care of automatically by the skin(s).
Alternatively, you could always have the Label be included in the BoxPane, but
just set it initially invisible ("visible='false'" in the .bxml file), and then
in response to your second button press, call "label.setVisible(true);".
Am I correct in thinking that's what you want to accomplish?

Great, I'll look into that.
I've got another (related?) question. Let's say I have a label defined inside a
box pane and a list of strings, all of which are wise sayings. Let me have 2
buttons.

Let the label be empty at first. Then if I click 1st button I need the label to
display the first saying. I click the button again, I get the second saying and
so on.
For the 2nd button if I click it, the label gets added to the box pane at
first, then shows the saying, and then carries out repaint operation. How to do
both of these?
