Hey, how do you use Sliders in Java?

Question

I'm on the second part of the lab and I'm struggling to figure out how to get the brush size dependent on the slider.

Answer 1

the Slider class has a function call getValue(). I would save the value of the slider in a variable by calling SliderObject.getValue() and use it for the brush size. You should find the code to set the brush size in the mousePressed() function or somewhere around.

Answer 2

You are able to add what is called a Listener to the slider which will allow you to run some code when it changes. Try reading this: https://www.geeksforgeeks.org/javafx-slider-class/
