Code Explanation

final ButtonBuilder buttonBuilder = new ButtonBuilder();

Constructs a new ButtonBuilder. You can view the documentation here.

You can reuse the builder, so you won't need to create a new ButtonBuilder every time you want to create a new button.

---

buttonBuilder.setColumnIndex(10);
buttonBuilder.setRowIndex(10);

This tells the builder to place the button at position (10x, 10y).

---

buttonBuilder.setText("Click Me");

This sets the text on the button, so this button will display "Click Me".

---

buttonBuilder.setOnClickFunction(() -> System.out.println("You clicked a button."));

This is an optional setter which gives the button a function to run when it's clicked.

In this case, the function will print "You clicked a button." when the button is pressed.

---

panel.addComponent(buttonBuilder.build());

This builds the button and adds it to the panel.
