Question

How to make the app ui resize itself automatically when I make it fullscreen?

Comments

Do you mean to ask how it's possible to make the app window size smaller after adjusting it to be fullscreen initially?

---

For now the program doesn't fit the whole window when I run it. Some buttons that should be on the right are on the center, and the whole layout looks disarranged. What I am trying to do is to make the layout shrink/expand based on if the window is full screen or not.

I think you have to use a border pane from the scene builder, instead of a normal pane. I think this might solve the problem you are facing. Hope this helps.

Answer 2

I know you can do this with relative units in CSS. w3schools has a good page on them here: https://www.w3schools.com/cssref/css_units.asp.

You can attach a CSS stylesheet to your fxml pages by adding
stylesheets="@stylesheetname.css"

Hope this helps!
