The AttachmentDetailView class is a standard detail view for managing attachments in the application. It extends the StandardDetailView class specialized for the Attachment entity type. The view allows uploading files, displaying previews, and adapting the UI depending on the file type (e.g., image, PDF, or code file). This class utilizes various UI components for handling and displaying attachment data: - JmixImage: Displays image previews. - CodeEditor: Displays text/code content for textual or code-based files. - IFrame: Renders PDF previews. - FileStorageUploadField: Allows file uploads. Additionally, it integrates services such as FileStorage and FileService to handle file-related operations. Annotations: - @Route: Defines the route path for the view. - @ViewController: Specifies the controller name for defining the view logic. - @ViewDescriptor: Provides the XML descriptor for the view. - @EditedEntityContainer: Links the view to the data container for editing entities. Event subscriptions and methods: - onFileUploadComponentValueChange(AbstractField.ComponentValueChangeEvent): Handles changes in the file upload field and updates the corresponding file preview. - onInitEntity(InitEntityEvent): Invoked during entity initialization for additional setup. - handleChange(): Updates the UI previews based on the type of file uploaded.

      @Subscribe("fileUpload") public void onFileUploadComponentValueChange(com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<io.jmix.flowui.component.upload.FileStorageUploadField,?> event)
      Handles the value change event for the file upload component. This method is triggered when the value of the associated file upload field changes. It processes the newly uploaded file, updates the preview components, and adapts the UI depending on the file type (e.g., image, PDF, or code file).
      Parameters:
      event - the event object containing information about the value change, including the source component and the new value of the file upload field

    • onInitEntity

      @Subscribe public void onInitEntity(io.jmix.flowui.view.StandardDetailView.InitEntityEvent<Attachment> event)
      Handles the initialization of a new or an existing `Attachment` entity. This method is triggered during the entity's initialization phase. It checks whether the entity is newly created or already existing. If the entity is not new, it disables the file upload component. Additionally, it invokes a method to process and adjust the UI based on the current file associated with the entity.
      Parameters:
      event - the initialization event containing the `Attachment` entity
