SECTION 2: CUSTOM WIDGET DEVELOPMENT (ZUIX.JS FRONTEND)

Widgets are dynamically loadable Web Components running in Shadow DOM. They consist of HTML (View), CSS (Style), and JavaScript (Controller).

Required CSS dependency check before returning a widget

Inspect the FINAL HTML and CSS before emitting any ordinary, composite or presentation widget. Do not assume the host or another widget imports its styles: each widget is isolated in Shadow DOM.

• If the HTML uses ANY layout or self attribute, the widget CSS MUST import assets/styles/flex-layout-attribute.min.css.
• If the HTML uses material-symbols-outlined or material-symbols, the widget CSS MUST import assets/styles/widget-ui.css. This file supplies icon/control styling; it DOES NOT supply FLA layout rules. Importing it alone cannot implement layout="column ...".
• Emit all required @import statements once at the very beginning of the CSS string, before selectors or other style rules. Do not put them in HTML, the controller, parent-document styles, or after CSS rules.

For a widget with BOTH layout attributes and Material Symbols, start CSS exactly with:

@import 'assets/styles/flex-layout-attribute.min.css';
@import 'assets/styles/widget-ui.css';

Use the documented FLA vocabulary: layout="row center-left", layout="row center-justify", layout="row center-right", layout="column top-stretch" or layout="column center-center". Do not invent center-between, center-start or center-end. Put self alignment/sizing in a SEPARATE attribute, e.g. self="stretch size-x1"; never put self-stretch inside layout.

Final internal check: scan the HTML for layout/self attributes and icon classes, then verify their imports exist in the actual CSS output. If you intentionally avoid FLA, omit its attributes and implement all needed display/direction/alignment in explicit CSS instead. Keep fixed-size icons and compact controls from unintentionally inheriting full-row width. Shared widget-ui.css hides spans in disabled buttons; when navigation must keep its label/icon, override that behavior within the widget (e.g. .nav-btn:disabled span { display: inline-block; opacity: 1; }).

2.1 Critical Rules (VIOLATION = BROKEN WIDGET)

1. ASSET MANAGEMENT:

• Prefer local assets for UI and styling: Do NOT use external CDNs for Fonts, Icons, or CSS. Assume these are hosted locally.
• Chart.js, Anime.js and Three.js are available as local JavaScript assets; use the entry points below. Other external JavaScript libraries require an explicit user request; do not silently add a CDN dependency.

1. ELEMENT ACCESS & STYLING:

• Access: Use this.field('my_el') for elements declared with the # directive attribute. Use this.view().find('valid_query_selector') to get elements within the view. (Both return a ZxQuery Object).
• Style: Use .css({ 'color': 'red' }). NEVER use .style directly on this.field(). DO NOT SET the background color of a widget if you want it to inherit theme settings.
• Raw DOM: Use this.field('my_el').get() and this.view().find('query_selector').get() if you absolutely need the HTMLElement.
• IMPORTANT: Inside the controller this is the ControllerInstance, this.$ is the view (ZxQuery). Inside any element of the View (HTML), this is the HTMLElement, $this is the ZxQuery-wrapped this, context is the ComponentContext with context.model() and other instance members.

1. HTML IDS (Binding):

• Use snake_case (e.g., #my_value).
• NEVER use CamelCase (e.g., #myValue is INVALID).

1. SYNTAX & LOGIC:

• Events: Never use $event. Always use event or the scoped context.
• Interpolation: Never use {{ variable }}. NEVER use Mustache syntax. Use the framework-specific data-binding via # attributes, or via @ attributes (e.g. @set="this.innerHTML = model.name").
• Active Refresh (@): Attributes starting with @ (e.g., @set, @if, @hide-if) are evaluated ONLY if the element is visible. To force evaluation even when the element is not visible (e.g., display: none or off-screen), you MUST include the @active attribute on the same element.
• Logic: @if is a logic branch, not a display toggle. Manage visibility explicitly via CSS classes or this.view().show()/hide().

1. UI SAFE ZONE: The host overlays a settings button in the Top-Right corner (48x48px).

• Action: Add padding-right: 48px; ONLY to your Header or Top Row.

1. CONTEXT SEPARATION:

• `this.model()`: Reactive Proxy for text/values.
• `this.declare()`: View Context for Methods/Logic.

1. SHADOW DOM: CSS is scoped. Use :host { display: block; }. The generated CSS must be bulletproof to prevent Shadow DOM layout collapse. Define the :host and root .container layout for the selected preset or free-size mode, following section 2.9.

2.2 Controller Configuration (settings)

Defining the settings object in the class is mandatory. You MUST always include defaultSize.

class MyWidget extends ControllerInstance {
  settings = {
    moduleSelect: {
        fieldFilter: 'Status.Level',
        // CRITICAL LIGHTING DEFINITIONS FOR 'typeFilter':
        // - 'Light' = Specifically a binary light (0/1 ON/OFF)
        // - 'Dimmer' = Dimmable light; check the actual field's value range
        // - 'Color' = Color LED light (RGB/HSB)
        typeFilter: 'Light,Dimmer,Color'
    },
    /**
     * @type {'' | 'small' | 'medium' | 'big'}
     * @description The default widget size. Use an empty string '' for an unconstrained,
     * CSS-driven size. Let the CustomWidget host apply the selected size.
     */
    defaultSize: 'medium',
    // Allowed user presets. If defaultSize is '', consider keeping this empty [] to disable manual resizing.
    sizeOptions: ['small', 'medium', 'big']
  };
}

Module selection contract:

• Valid module types are dimmer, color, doorlock, doorwindow, generic, light, mediareceiver, mediatransmitter, program, sensor, switch, shutter, motor, thermostat, and videoinput. Matching is case-insensitive.
• Use comma-separated names without spaces. Types in typeFilter are alternatives (OR); fields in fieldFilter are also alternatives (OR). When both filters are set, the module must match BOTH groups (AND). Selection includes online modules only.
• For a general level display, use fieldFilter: 'Status.Level' and omit typeFilter unless the widget requires specific device types. A lighting widget must include Color when it supports color lights.
• An omitted, empty, or any filter imposes no restriction for that group. At least one active filter is required to populate the module selector; leaving both groups unrestricted currently produces an empty list.
• moduleSelect is OPTIONAL. Omit it for standalone widgets such as games, calculators, clocks, or interactive explanations. Such widgets must work without boundModule.
• If binding is needed, render a useful unbound state and expose a user action calling this.configure(). Check that boundModule and each required field exist before using them. A field list does not guarantee that every listed field exists.
• Current CustomWidget CSS declares small as 302x168px, medium as 302x316px, and big as 492x316px, with padding and card constraints applied separately. These are host layout declarations, not guaranteed inner canvas dimensions. Use the actual view size for canvas/chart sizing and adapt on resize.
• Include defaultSize in sizeOptions when manual resizing is enabled. Use sizeOptions: [] to disable manual resizing when a free, CSS-driven layout is appropriate.

2.3 Controller Logic & Framework APIs

• `onInit()`: Pre-load external libs (e.g., zuix.using).
• `onCreate()`: MAIN ENTRY POINT.
• Pattern: Define a viewContext object with Methods and pass it to this.declare(viewContext).
• Binding Check: Initialize the view and its methods first. If binding is needed and no module is associated, render the unbound state before returning. Standalone widgets must not depend on a bound module.
• Subscribe (CRITICAL EXISTENCE CHECK): You MUST ALWAYS verify that a field exists before subscribing to it. Failing to do so causes a FATAL runtime crash.
• Correct: const f = this.boundModule.field('Sensor.Name'); if (f) { this.subscribe(f, callback); }
• `onDispose()`: MANDATORY FOR MEMORY SAFETY. You MUST always generate this method in the controller class. It is strictly required to clear interval/timeout handles with clearInterval/clearTimeout, cancel animation frames with cancelAnimationFrame, unsubscribe from subscriptions created directly by the widget, and remove custom event handlers to prevent memory leaks. Even if your code doesn't actively use timers yet, generate an empty onDispose() method.
• `this.apiCall('domain/address/method', payload)`: FRONTEND ONLY (UI/Widgets). Sends a request from the widget to a backend service. Returns an Observable.
• 🚨 CRITICAL PAYLOAD PARSING: The subscription receives an object structured as { code: number, response: any }. You MUST use `data.response` to access the actual JSON/array returned by the backend API. Do not assume the raw array/object is returned directly at the root.
• Correct Usage: this.apiCall('Custom/MyApi').subscribe({ next: (data) => { const payload = data.response; /* process payload */ } });
• `this.configure()`: FRONTEND ONLY. Programmatically opens the custom widget configuration dialog (Bound Module Selection).
• `this.showSettings()`: FRONTEND ONLY. Programmatically opens the module settings dialog.
• `this.translate(key)`: Returns an Observable from translate.get('WIDGETS.' + key). Subscribe to receive the translated string; do not assign the Observable to a text field. Track and unsubscribe any subscription created directly by your controller in onDispose().
• `this.init, this.create, this.dispose, this.update, this.log`: Are RESERVED methods NEVER OVERWRITE them.

2.4 State Management Strategy (CRITICAL)

When handling multiple fields, avoid passing values as arguments to a central update function.

• BAD: updateUI(level, color) -> Prone to type mismatch errors.
• GOOD (Store-then-Render):

1. Store: In the callback, parse and save to this.state.
2. Render: Call a parameter-less this.refreshUI() method which evaluates this.state and pushes changes to this.model().
