PUI - A Processing UI library

PUI is a simple but maleable library for Processing 3.0+ aimed at supporting quick user interface design. PUI runs on a basic synchornous flow and can be added to any processing sketch to introduce a new depth of control.

Setting Up A PUI

Adding a PUI to your Processing Sketch consits of three main steps:

• Initializing PUI elements you desire in the setup() block
• Registering PUI elements with a newly created ObjectSelector
• Running the ObjectSelector inside of the draw() block

Example

The below code snippet shows how a Processing sketch can be setup to create a 500 by 500 pixel canvas on which a HorizontalContinuousSlider is drawn.

public void settings() {
    	size(500,500);
    }

public void setup() {
    	fill(120,50,240);
    	o = new ObjectSelector(this);
    	slider1 = new HorizontalContinuousSlider(20,200,100,4,this);
    	o.register(slider1);
    }

public void draw(){
    	o.run();
    } 

First, the size of the sketch and its background are set. Then, a new ObjectSelector is created for this (the current PApplet). Then, a slider is created as a HorizontalContinuousSlider with a location of (20,200) on the canvas, with a length of 100 and a button size of 4 pixels, and the this keyword is included again to show it is being drawn on the current PApplet. Lastly, the ObjectSelector is run during the draw() block which listens for all PUI events and draws all elements.

Current PUI Elements

PUI is still in its early developmental phase, and new elements are being designed and thought of every week while this project is active. If you have any interest in contributing to this fun project please contribute your thoughtful ideas and help make PUI an even more user friendly and enjoyable expierence for all!

Sliders

There are four types of sliders. HorizontalContinuousSlider, HorizontalDiscreteSlider, VerticalContinuousSlider, and VerticalDiscreteSlider.

If a slider is continuous, this means the indicator (or button) on the slider can rest anywhere on the slider track. If a slider is discrete, this means there are a user-defined amount of places on the slider track that the indicator can lie. Intuitively, a horizontal slider goes from left to right, while a discrete slider goes up to down.
