RustyKnight / CircleProgressTest.java

Created July 26, 2018 11:12

An implementation of circular progress bar concept in Java/Swing using the 2D Graphics, Shapes API


	import java.awt.BasicStroke;
	import java.awt.Color;
	import java.awt.Dimension;
	import java.awt.EventQueue;
	import java.awt.Graphics;
	import java.awt.Graphics2D;
	import java.awt.RenderingHints;
	import java.awt.event.ActionEvent;
	import java.awt.event.ActionListener;

RustyKnight / Animation.swift

Last active August 2, 2018 22:39

A really basic implementation of "animatable" concept - something which can generate a time based progression for the purpose of animation

	import Foundation
	import UIKit

	// MARK: Base animation

	public class Animation {

	internal var displayLink: CADisplayLink?

	public var isRunning: Bool {

RustyKnight / UIImage+CircularProgress.swift

Last active August 2, 2018 09:03

An extension to provide a "circular progress" effect, which makes the image grey scale, generates a "pie slice" progression path and overlays the "exposed" color image


	internal extension FloatingPoint {
	var degreesToRadians: Self { return self * .pi / 180 }
	var radiansToDegrees: Self { return self * 180 / .pi }
	}

	extension UIImage {

	func circularProgress(_ progress: Double,
	grayScaleAlpha: Double = 1.0,

RustyKnight / ImageViewProgess.swift

Created August 2, 2018 23:38

A implementation of a circular progress image based on a UIImageView


	import Foundation
	import UIKit

	public class ImageViewProgess: UIImageView {

	fileprivate var actualImage: UIImage?
	fileprivate var grayScaleImage: UIImage?

	@IBInspectable public override var image: UIImage? {

RustyKnight / Test.java

Created August 9, 2018 08:20

Demonstration of using two threads to synchronise the printing of odd and even lists of numbers, so they appear in order

	import java.util.concurrent.locks.Condition;
	import java.util.concurrent.locks.ReentrantLock;
	import java.util.logging.Level;
	import java.util.logging.Logger;

	public class Test {

	public static void main(String[] args) throws InterruptedException {
	ReentrantLock lock = new ReentrantLock();
	Condition con = lock.newCondition();

RustyKnight / AbstractAnimatable.java

Last active August 19, 2018 01:26

A simple Java/Swing based time based animation framework

	import java.time.Duration;
	import java.time.LocalDateTime;

	public abstract class AbstractAnimatable<T> implements Animatable<T> {

	private Range<T> range;
	private LocalDateTime startTime;
	private Duration duration = Duration.ofSeconds(5);
	private T value;
	private AnimatableListener<T> animatableListener;

RustyKnight / String+Trimmed.swift

Created August 29, 2018 22:01

Simple "trimming" support for String


	import Foundation

	extension String {
	var trimmed: String {
	return self.trimmingCharacters(in: .whitespacesAndNewlines)
	}

	var isEmptyWhenTrimmed: Bool {
	return trimmed.isEmpty

RustyKnight / UIViewController+DismissKeyboard.swift

Created August 29, 2018 22:03

Dismissible keyboard support for iOS


	import Foundation
	import UIKit

	// I'm not a fan of this, but this will allow us to maintain state beyond the capabailities of the the extension API
	fileprivate var cache = NSMapTable<UIViewController, UITapGestureRecognizer>(keyOptions: .weakMemory, valueOptions: .weakMemory)

	extension UIViewController {

	fileprivate var tapRecognizer: UITapGestureRecognizer? {

RustyKnight / UIViewController+HideKeyboard.swift

Created August 29, 2018 22:05

Extension to hide the keyboard (resign first responder) globally


	import Foundation
	import UIKit

	extension UIViewController {

	@objc func hideKeyboard() {
	UIApplication.shared.sendAction(#selector(UIApplication.resignFirstResponder), to: nil, from: nil, for: nil)
	}

RustyKnight / UIViewController+KeyboardDisplacer.swift

Created August 29, 2018 22:05

Extension to display the view when keyboard is presented


	import Foundation
	import UIKit

	// I'm not a fan of this, but this will allow us to maintain state beyond the capabailities of the the extension API
	fileprivate var cache = NSHashTable<UIViewController>(options: .weakMemory)

	extension UIViewController {

	fileprivate var isInstalled: Bool {
