   • Web Components vs. Widgets: Is there a difference?

     Top Answer

     Answered Nov 23, 2013 · 8 votes

     Web Components is an umbrella term for a group W3 standard technologies composed of: Custom Elements, Shadow DOM, HTMLImports, and HTMLTemplates. These four specs working in concert form Web Components, and afford you all the abilities old school UI libraries like jQuery UI or Ember do, while allowing you to do so in a standard package browsers will natively understand.

     One huge benefit, is that when you use Web Components, it makes it far easier for the browser to keep your code/app on the "fast path". The fast path, is the accelerated portions of the browser that are able to run as fast as possible and be optimized by underlying mechanisms like the JS engine's JS-to-native code compilation JIT, and low-level DOM systems that minimize things like the import of assets, UI reflows, and layout recalcs.

     Here are two libraries that make development of Web Components even easier: http://x-tags.org/ & http://www.polymer-project.org/

   • What are the parent components and what are the child components?

     Top Answer

     Answered Aug 12, 2014 · 3 votes

     The meaning can be summed up as:

     • Parent component has other components inside it.
     • Child component is contained within another component.

     Here is the simple source code that created the above image.

     import java.awt.*; // package import for brevityimport javax.swing.*; import javax.swing.border.TitledBorder;public class ParentAndChildComponent { public JComponent getGUI() { JPanel p = new JPanel(new GridLayout(1,0,20,20)); p.setBorder(new TitledBorder("Panel: Child of frame/Parent of labels")); for (int ii=1; ii<4; ii++) { JLabel l = new JLabel("Label " + ii + ": Child of panel & frame"); p.add(l); } return p; } public static void main(String[] args) { Runnable r = new Runnable() { @Override public void run() { JFrame f = new JFrame("Frame: Parent of all other components"); f.setContentPane(new ParentAndChildComponent().getGUI()); f.pack(); f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); f.setLocationByPlatform(true); f.setVisible(true); } }; SwingUtilities.invokeLater(r); }}

     ..if we override the paintChildren() method when painting, the components that were already on the screen don't appear any more).

     Don't mess with the paintChildren() method. In over a decade of Swing development (including a lot of custom painting examples), I've needed to override that exactly 0 times.

     For custom painting in a Swing component that extend from JComponent (typically a JPanel) we would:

     • Override the paintComponent(Graphics) method to do custom painting.
     • Call the super.paintComponent(Graphics) method to ensure that any children or borders of the custom component are painted.

   • Are Web Components actually useable in IE11 and Edge?

     Top Answer

     Answered Apr 14, 2020 · 16 votes

     If all you want is Custom Elements then you can get them to work with IE11 and Edge. Shadow DOM and HTML Imports can work with IE11 and Edge as well, but I, personally, don't like using Shadow DOM except on browsers that support it natively.

     Firefox and Edge will work with just the regular polyfill.

     IE11 needs to be Transpiled into ES5 and use the polyfill.

     If you are using the ES5 transpiled code on a newer browser, that supports class then you need to use the file custom-elements-es5-adapter.js

     Some people use webcomponents-lite.js which will auto-load the needed polyfill files. Others load the specific polyfill, like webcomponents-hi-ce.js (HTML Imports and Custom Elements) or webcomponents-sd-ce.js (Shady DOM and Custom Elements)

     https://github.com/webcomponents/polyfills/tree/master/packages/webcomponentsjs

     UPDATE

     If you are using a newer version of Edge, the versions that use Chromium, then support for V1 components is now built in.

   • What are Web Accessibility Issues and How to Addressed by Web Developers ?

     Web accessibility allows individuals with disabilities, including those who are visually impaired, hearing-impaired, have mobility issues, or cognitive impairments to use the internet. Accessibility issues can adversely affect their ability to connect online.

     Importance of Web Accessibility:

     The ability to access websites is an essential right for everyone, including those living with disabilities. This includes people with impaired vision, hearing difficulties, mobility issues, and cognitive impairments. Accessibility issues can create serious impediments to the online presence of disabled users, preventing them from accessing sites. The importance of internet accessibility is recognized legally by the Americans with Disabilities Act (ADA) which states that all public businesses must provide a website open to disabled customers. Furthermore, research has shown that providing an accessible website raises customer satisfaction and improves the client base. Thus, it is vital for everybody to have the capacity to interact with the digital landscape. 

     Website Accessibility Checklist:
