In our previous examples, we built the GUI from within the main method, and then built the GUI into an external class. We said that was beneficial in case we wanted to extend a class, like we will here. While this will create some extra work on the front end, it will make things easier…
In our previous example, we set up the GUI Frame inside of the main function. However, we want to move it to a different class so that we can separate out the logic of application from the interface. This will allow multiple people to work on different parts of the application easier, make it easier…
So our first example will be to build a simple GUI interface that launches from within the main. This isn’t a standard procedure, but is good to get a start into see how components work. Typically we’d have a separate class which would call and load the window. We’re going to start with a basic…
In early versions of Java, there was a GUI (Graphical User Interface) measure using AWT (Abstract Windowing Toolkit). However, it was quickly replaced with Swing, part of the JFC (Java Foundation Classes) for a couple of reasons. Java Foundation Classes (JFC) are a set of GUI components which simplify the development of desktop applications. Java…
The MVC (Model View Controller) pattern is not unique to Java, not by any stretch of the imagination. You often see it in web designs. the idea is to separate out each object into a 3 tier system, very similar to how you would in a traditional 3 tier system. Controller The controller works on…
The factory design pattern is one of the original design patterns by the Gang of Four. It follows the idea of using implementation of interfaces instead of different classes, and allows you to request a object from the factory. Now design patterns are not specific to a language. You will find that sometimes these patterns…
We’re going to work to remove a list item by swiping left or right. This is a common design pattern you see in lots of apps. Let’s start by creating a basic Flutter app, the way we’ve done before. Then removing the comments and existing widgets so we’re left with a blank app. Building the…
Working with gestures is fairly simple as Flutter was designed to work in the mobile environment. Let’s start by creating a basic Flutter app, the way we’ve done before. Then removing the comments and existing widgets so we’re left with a blank app. The Simplest Gesture – the Tap The onTap() is very similar to…
