By creating the object of Frame class (Association).NoteThe Java Foundation Classes (JFC) are a set of GUI components which simplify the development of desktop applications.įigure 10.2 :Hierarchy of Java Swing classesĬommonly used methods in Component class:įigure 10.3 :Commonly used methods in Component class: The javax.swing package provides classes for Java Swing components such as JButton, JTextField, JTextArea, JRadioButton, JCheckbox, JMenu, JColorChooser etc. ![]() Java Swing provides better lightweight components than AWT. It is built on the top of AWT (Abstract Windowing Toolkit) API and entirely written in Java. Java Swing is a part of Java Foundation Classes (JFC) that is used to create window-based applications. We're hiring! Consider joining our teams who work on the Zalando Mobile App and build user experiences for our customers.Chapter 10 - Java Swing Chapter 10 Java Swing We were impressed with how easy it was to get started and managed to build a fairly performant Compose powered implementation of our home screen. Please see the sample app repo for the code as well as my first attempt at working with the Compose Navigation library.ĭuring our recent Hack Week, we had a chance to spend more time with Compose. In this article, we have seen how much of the layout behavior defined in the flexbox spec has a direct analog in Compose and a few places where we have to do a bit more work to approximate certain concepts. The above code results in the following UI: Conclusion Compose has Row and Column composables that work for simple horizontal and vertical fun FlowRowExample () Flex Directionįlex direction specifies whether items are arranged vertically or horizontally. Let's start with the flex attributes, which describe the direction, size, and horizontal/vertical alignment of a layout's children. Insert a "UI" where necessary while reading if you'd like. I also built this sample app, parts of which I will reference in code examples below.īefore we continue, yes, I know technically it's called Compose UI and not simply Compose, but as Jake said, most of us are already thinking of it this way. However, there is no Flexbox composable that does it all and no blog post explaining how flexbox concepts map to Compose, so I wrote this one. Compose offers numerous layout composables, many with bits of flexbox like behavior. Thus far, we have been using Litho on Android and Texture on iOS (both of which use the flexbox based Yoga layout engine) for rendering backend driven screens because they support things that are essential when building fully dynamic UI at runtime such as async layout, efficient diffing of changes, and view flattening.Īs Google prepares Jetpack Compose (now in beta) for production release, we have started evaluating it as a successor to Litho. In the Zalando Fashion Store apps, we are using flexbox to define the layout of our backend-driven screens, which I spoke about previously. This type of layout is ideal for grids or other groups of views with varying sizes. Readers familiar with ConstraintLayout can think of flexbox as conceptually similar to the Flow virtual layout it supports. For this reason, it is widely used on the web and even on mobile. The CSS Flexible Box Layout specification (AKA flexbox) is a useful abstraction for describing layouts in a platform agnostic way.
