user interface – Is there a universal UI builder for Web?

My hatred of UI design has kept me away from web development for years. The thought arranging buttons, forms, textboxes pixel by pixel makes me want pull my hair out, it’s the equivalent of nails on a chalkboard for me. In C#, Java, C++ etc. I can use Form Designers and Toolboxes to drag and drop UI elements and arrange them enough to get the job done.

I want something equivalent in webdev where I can drag and drop the elements and use cursor to arrange them and then get to the interesting part of my projects. I’d rather do any amount of algorithm/math work than a little of UI design.

Is there something like this in Web development?

blocks – Adding section components with populated fields to a Layout Builder enabled node

I’m working on migrating content from fieldable panels panes in D7 to Layout Builder in D8. So far, I’ve managed to extract the content I need from my D7 database, but I’ve been unable to add that content to layout builder section components. Backing up a bit, I’m currently trying to just add some inline blocks with sample content to a layout builder section in an attempt to determine how to populate the fields, as follows:

    /* 
      Add an inline block of 'basic' type to a section
      'basic' blocks only have a field called "body" of type "Text (formatted, long, with summary)"
    */
    $section = new Section('two_column');

    $testcomponent = new SectionComponent($this->uuid->generate(), 'first', (
      'id' => 'inline_block:basic',
      'label' => 'Test component label',
      'label_display' => 'visible',
      'body',(
        'value'=>'Test',
        'format'=>'limited_html_text',
      )
    ));
    $section->appendComponent($testcomponent);

After I run my migration, I end up with a node with a inline block of “basic” type in the “first” region, as expected, but it’s empty aside from the label. Could someone advise me on how to set field values for section components?

browser – Developer Documentation Builder

I am trying to build a developer documentation for my web app in the style of this: https://firebase.google.com/docs/firestore/query-data/get-data

The features I am looking for is that it has a left vertical navigation bar, and the documentation text is on the right, along with code sections. Instead of me creating everything from HTML/CSS from scratch, I am wondering if there is a website builder that I can use to drag and drop the features I want such as the vertical navigation bar, and code blocks, etc?

java – How do I connect my JavaFx Scene Builder application to the MySQL database?

I am doing an application in Java and I used Scene Builder to create the graphical user interface.

My application saves employees. The new buttons for editing and deleting do their job. However, you save the changes in an XML file. I want you to connect to a database and save those changes to that database by inserting, changing, or deleting people in the application (using hibernation).

Application interface

Next, I leave the interface controller code:

                }

                String filtroMinuscula = newValue.toLowerCase();

                if (person.getFirstName().toLowerCase().indexOf(filtroMinuscula) != -1){

        sortedData.comparatorProperty().bind(personTable.comparatorProperty());

        personTable.setItems(sortedData);
    }

}

I understand that in the new edit and delete buttons, I have to implement this change to the database with a type code:

SessionFactory factory = HibernateUtils.getSessionFactory();
                Session session = factory.openSession();

                   session.getTransaction().begin();
                   session.delete();
                   session.getTransaction().commit();

I've managed to put some occurrences of Persona in the database, but I do it when I initialize the app so that it contains some content when it starts. However, I want the changes to be made again, edited and deleted to affect the database, but I don't give the key on how to do it, can someone help me?

Thank you so much! If necessary, I can post more code if it helps.

8 – How do I remove context links? (except in the Layout Builder)

When using the layout builder module, the context link module is a hard dependency. This works quite well in the context of the layout builder. But I don't make these links anywhere else because they are not helpful at best elsewhere and, in the worst case, completely confuse my frontend topic.

I have already written a custom theme negotiator to force my admin theme into layout creation mode.

But I don't know how to remove all context links when I'm in the frontend. My current ugly hack is

function mymodule_page_attachments(array &$page) {
  $isAdminTheme = (Drupal::service('theme.manager')->getActiveTheme()->getName() == Drupal::config('system.theme')->get('admin'));

  /**
   * Suppress the contextual links on frontend themes, we only want it
   * for layout builder in admin theme
   */
  if (!$isAdminTheme) {
    $page('#attached')('library') = array_diff($page('#attached')('library'), ('contextual/drupal.contextual-links'));
  }
}

and an additional rule in my frontend CSS

.contextual-toolbar-tab, (data-contextual-id) {
  display: none !important;
}

This at least hides the context editing pen in the frontend, but the context links are not really removed. It does not work at all in other administrative areas, e.g. for thumbnails of media entity images in my custom administrator views.

Can someone tell me how to remove contextual links reliably and cleanly? I don't want to have them anywhere except in layout creation mode.
