+# UI Layout Definition Format
+
+**Version:** 1.1  
+**Documentation Version:** 1.1  
+**Author:** Dalibor Votruba  
+**URL:** [quadarax.com/ui-layout-def](https://quadarax.com/ui-layout-def)
+
+A comprehensive XML-based format for describing user interface layouts with inheritance, pattern definitions, view organization, and platform-specific extensions. This format enables cross-platform UI generation with strict validation and modular component libraries.

+
+## Overview
+
+The UI Layout Definition Format provides a standardized way to define user interfaces that can be translated to various platforms (Windows Forms, WPF, Qt, Web, Mobile). It emphasizes:
+
+- **View-Based Organization**: Logical grouping of related UI components by business function
+- **Separation of Concerns**: Pattern definitions separate from usage
+- **Inheritance**: Base wireframes and views with specific overrides
+- **Validation**: Strict constraints ensure consistent, valid UIs
+- **Modularity**: External pattern, view, and validation includes
+- **Cross-Platform**: Platform-specific control libraries
+- **MVVM Support**: Direct mapping to view models and business logic
+
+## Core Concepts
+
+### 1. View-First Design (NEW in v1.1)
+Views represent logical business functions (ProductView, OrderView) that group related windows and define shared data context and behaviors.
+
+### 2. Patterns-First Design
+All controls and structures must be defined in the `<patterns>` section before use in windows.
+
+### 3. Inheritance Hierarchy
+- Views can inherit from other views
+- Controls can inherit from other controls
+- Windows can inherit from wireframe layouts
+- Attributes can be overridden at any level
+
+### 4. Slot-Based Composition
+Wireframes use slots as placeholders that windows can fill with specific content.
+
+### 5. Constraint Validation
+Comprehensive validation rules ensure UI consistency and platform compliance.

+```
+
+## View Definitions
+
+### View Concept
+
+Views are logical containers that group related windows, dialogs, and UI components that work together for a specific business function. They provide:
+
+- **Logical Organization**: Group UI components by business purpose
+- **Data Context**: Shared state management within the view
+- **Navigation**: Centralized navigation logic
+- **Dependencies**: Clear relationships between views
+- **Code Generation**: Generate view classes with proper structure
+
+### Basic View Structure
+
+```xml
+<view name="ProductView" type="business-entity" category="core" inherits="BaseEntityView">
+  <description>Product management functionality including listing, editing, and details</description>
+  
+  <!-- View metadata for code generation -->
+  <metadata>
+    <model-class>Product</model-class>
+    <view-model-class>ProductViewModel</view-model-class>
+    <controller-class>ProductController</controller-class>
+    <permissions>product.read,product.write</permissions>
+  </metadata>
+  
+  <!-- View dependencies -->
+  <dependencies>
+    <view-ref name="CategoryView" relationship="lookup" required="false" />
+    <view-ref name="SupplierView" relationship="reference" required="false" />
+    <shared-component name="FileUploadComponent" required="true" />
+  </dependencies>
+  
+  <!-- Shared data context -->
+  <data-context>
+    <property name="currentProduct" type="Product" scope="view" />
+    <property name="productList" type="ProductList" scope="view" />
+    <property name="selectedCategory" type="Category" scope="shared" />
+  </data-context>
+  
+  <!-- Window associations -->
+  <windows>
+    <window-ref name="ProductListWindow" role="main" default="true" />
+    <window-ref name="ProductEditDialog" role="editor" modal="true" />
+    <window-ref name="ProductDetailsWindow" role="viewer" />
+  </windows>
+  
+  <!-- View-level navigation -->
+  <navigation>
+    <action name="show-list" target="ProductListWindow" />
+    <action name="edit-product" target="ProductEditDialog" context="currentProduct" />
+    <action name="view-details" target="ProductDetailsWindow" context="currentProduct" />
+  </navigation>
+  
+  <!-- Shared behaviors -->
+  <behaviors>
+    <behavior name="refresh-data" scope="view" />
+    <behavior name="validate-product" scope="view" />
+    <behavior name="save-changes" scope="view" />
+  </behaviors>
+</view>
+```
+
+### View Types and Categories

+**View Types:**
+- `business-entity` - Product, Order, Customer management
+- `process-flow` - OrderProcessing, Checkout workflows
+- `dashboard` - MainDashboard, ReportsView
+- `utility` - Settings, UserPreferences
+- `wizard` - Setup wizards, guided processes
+- `composite` - Views composed of multiple sub-views

+
+### View Inheritance
+
+```xml
+<!-- Base entity view -->
+<view name="BaseEntityView" type="base" category="framework">
+  <windows>
+    <window-ref name="BaseListWindow" role="main" />

+  </behaviors>
+</view>
+
+<!-- Inherited view -->
+<view name="ProductView" inherits="BaseEntityView">
+  <!-- Inherits all windows, navigation, and behaviors from BaseEntityView -->
+  <!-- Can override or extend with additional functionality -->
+  
+  <windows>
+    <!-- Additional product-specific windows -->
+    <window-ref name="ProductCatalogWindow" role="catalog" />
+  </windows>
+  
+  <navigation>
+    <!-- Override base action -->
+    <action name="edit-entity" target="ProductEditDialog" context="currentProduct" />

+
+## Wireframe Inheritance
+
+Windows can inherit from wireframe layouts and override specific slots:
+
+```xml
+<window name="MainWindow" title="Main Application" wireframe="StandardAppLayout" view="MainView">
+  <attributes>
+    <attribute name="width" value="800" />
+    <attribute name="height" value="600" />
+  </attributes>
+  
+  <view-properties>
+    <role>main</role>
+    <default>true</default>
+    <data-context-binding>mainData</data-context-binding>
+  </view-properties>
+  
+  <slot-overrides>
+    <slot name="header-content">
+      <Label name="appTitle" text="My Application" />
+      <Button name="settingsButton" text="Settings" />
+    </slot>
+    
+    <slot name="main-content">
+      <Panel name="dashboardPanel">
+        <!-- Main content here -->
+      </Panel>
+    </slot>
+  </slot-overrides>
+</window>
+```
+
+## Window Definitions
+
+```xml
+<window name="WindowName" title="Window Title" wireframe="OptionalWireframe" view="AssociatedView">
+  <attributes>
+    <attribute name="width" value="800" />
+    <attribute name="height" value="600" />
+    <attribute name="resizable" value="true" />
+    <attribute name="modal" value="false" />
+  </attributes>
+  
+  <!-- NEW: View properties -->
+  <view-properties>
+    <role>main</role>
+    <default>true</default>
+    <modal>false</modal>
+    <data-context-binding>entityData</data-context-binding>
+    <parent-window>ParentWindow</parent-window>
+  </view-properties>
+  
+  <!-- For wireframe-based windows -->
+  <slot-overrides>
+    <slot name="content">
+      <!-- Slot content -->
+    </slot>
+  </slot-overrides>
+  
+  <!-- For direct layout windows -->
+  <Panel name="mainPanel">
+    <!-- Direct content -->
+  </Panel>
+</window>
+```
+

+## Best Practices
+
+### 1. View Organization
+
+- Group related windows by business function
+- Use inheritance for common view patterns
+- Define clear view dependencies
+- Document view responsibilities
+
+### 2. View Design Patterns
+
+- **Single Responsibility**: Each view should handle one business concept
+- **Dependency Injection**: Use view dependencies rather than tight coupling
+- **Data Context**: Define clear data scopes (view, shared, global)
+- **Navigation**: Centralize navigation logic within views
+
+### 3. Naming Conventions
+
+- Use PascalCase for view names with "View" suffix
+- Use descriptive names indicating business purpose
+- Group related views with common prefixes (OrderView, OrderItemView)
+
+### 4. Code Generation Strategy
+
+- Map views to view model classes
+- Generate navigation methods
+- Create dependency injection configuration
+- Generate view factory classes
+
+## Platform Support
+
+### Enhanced Platform Integration
+
+**Windows Forms / WPF**
+- Generate view classes with proper MVVM binding
+- Create dependency injection containers
+- Generate navigation services
+- Support for Windows-specific patterns
+
+**Qt / KDE**
+- Generate Qt view classes
+- Support for KDE desktop integration
+- Cross-platform Qt navigation
+
+**Web / HTML**
+- Generate MVC views or React components
+- Support for SPA routing
+- Progressive web app patterns
+
+**Mobile**
+- Generate platform-specific view controllers
+- Support for mobile navigation patterns
+- Responsive view layouts
+
+## Migration from Version 1.0
+
+### Backward Compatibility
+
+Version 1.1 maintains full backward compatibility with 1.0 documents. Existing documents will work without modification, but won't benefit from view organization features.
+
+### Migration Steps
+
+1. **Add Views Section**: Introduce `<views>` section
+2. **Group Windows**: Organize related windows into views
+3. **Add View Properties**: Enhance windows with view properties
+4. **Define Dependencies**: Specify view relationships
+5. **Update Validation**: Add view-specific validation rules
+
+### Gradual Migration
+
+You can migrate gradually by:
+- Adding views for new functionality
+- Keeping existing windows as-is
+- Gradually moving windows into views
+- Updating code generation templates
+
+## Code Generation
+
+### Generated View Classes (C# Example)
+
+```csharp
+// Generated from ProductView definition
+public class ProductView : BaseEntityView, IProductView
+{
+    public ProductListWindow ProductListWindow { get; private set; }
+    public ProductEditDialog ProductEditDialog { get; private set; }
+    
+    // Data context properties
+    public Product CurrentProduct { get; set; }
+    public ObservableCollection<Product> ProductList { get; set; }
+    
+    // Dependencies
+    public ICategoryView CategoryView { get; set; }
+    
+    // Navigation methods
+    public void ShowList() => ProductListWindow.Show();
+    public void EditProduct(Product product) => ProductEditDialog.ShowDialog(product);
+    
+    // View behaviors
+    public async Task RefreshData() { /* ... */ }
+    public async Task SaveChanges() { /* ... */ }
+}
+```
