2. Technical Architecture

Architecture Philosophy

MacroView Studio embodies enterprise IDE design principles:

• Extensible Plugin Architecture: New editors and tools integrate seamlessly
• MDI Framework: Multiple documents open simultaneously with tab management
• Separation of Concerns: Distinct editors for graphics, reports, and scripts
• Comprehensive Object Model: Domain models (DGT, Report, Metascript) with rich APIs
• Professional UI: Docking panels, toolbars, property grids, and tool palettes
• Server-Centric Design: Remote file operations and live SCADA connectivity

High-Level System Architecture

Architectural Patterns Applied

1. Multiple Document Interface (MDI) with Tabbed Management

Rationale: Enables simultaneous editing of multiple files while maintaining a cohesive workspace.

Benefits:

• Multiple files open simultaneously
• Context-sensitive menus adapt to active document
• Unified property editor reflects current selection
• Tab-based navigation for rapid switching

2. Strategy Pattern for File Editors

Rationale: Different file types require specialized editors with common interface.

Benefits:

• Unified file operations across editor types
• Easy addition of new editor types
• Polymorphic handling in main form
• Consistent user experience

3. Composite Pattern for Graphics Hierarchy

Rationale: Graphics contain nested groups, widgets, and primitives in tree structure.

Benefits:

• Uniform treatment of individual objects and groups
• Recursive operations (move, rotate, delete) on hierarchies
• Simplified persistence (save/load entire tree)
• Flexible grouping and ungrouping

4. Template Method Pattern for File Operations

Rationale: Common save/load workflow with editor-specific customization points.

// Base pattern in IStudioFileEditor implementations
public abstract class BaseEditor : Form
{
    // Template method defines overall structure
    public void Save()
    {
        if (!ValidateBeforeSave())
            return;

        PrepareForSave();

        try
        {
            PerformSave(EditedFile);
            OnSaveSucceeded();
        }
        catch (Exception ex)
        {
            HandleSaveError(ex);
        }
        finally
        {
            CleanupAfterSave();
        }
    }

    // Hook methods for customization
    protected virtual bool ValidateBeforeSave() => true;
    protected virtual void PrepareForSave() { }
    protected abstract void PerformSave(IFile file);
    protected virtual void OnSaveSucceeded() { }
    protected virtual void HandleSaveError(Exception ex) { }
    protected virtual void CleanupAfterSave() { }
}

Benefits:

• Consistent save/load behavior across editors
• Centralized error handling
• Easy to add pre/post save hooks
• Testable save workflow

5. Design Patterns and Best Practices

Core Design Patterns Summary

SOLID Principles Application

Single Responsibility Principle (SRP)

Each class has focused responsibility:

• GraphicEditor: Graphics editing UI
• DgtModel: Graphics document model
• ServerFileDialog: Server file browsing
• MacroViewConnection: SCADA connectivity

Open/Closed Principle (OCP)

Open for extension, closed for modification:

• Adding new widget: Extend Dgt base class
• Adding new editor: Implement IStudioFileEditor
• Adding new export format: Create AbstractExportToFileCommand subclass

Liskov Substitution Principle (LSP)

Derived classes substitutable for base:

• All Dgt subclasses render via Render(Graphics) method
• All editors work with IFile abstraction
• All export commands implement Execute() method

Interface Segregation Principle (ISP)

Clients depend only on needed methods:

• IStudioFileEditor: Minimal interface for file editors
• IDgtObject: Core graphic object contract
• IFile: Abstraction for file access

Dependency Inversion Principle (DIP)

Depend on abstractions:

• Editors depend on IFile interface, not concrete file classes
• Main form depends on IStudioFileEditor, not specific editors
• Graphics depend on IDgtObject, not concrete widget classes

Testing Strategy

Unit Testing:

• Widget rendering isolated from UI
• File serialization/deserialization
• Report generation logic
• Script parsing and execution

Integration Testing:

• Server connection and file operations
• Graphics loading/saving round-trip
• Report data binding end-to-end
• VNC protocol handshake

Manual Testing:

• UI/UX testing in real scenarios
• Performance testing with large graphics
• Compatibility testing across SCADA versions
• Remote file operations over slow networks

Error Handling Approach

Defensive Programming:

public void SaveGraphic(IFile file)
{
    // Validate preconditions
    if (file == null)
        throw new ArgumentNullException(nameof(file));

    if (!file.CanWrite)
        throw new InvalidOperationException("File is read-only");

    // Check for unsaved dependencies
    if (HasUnsavedBitmaps())
    {
        var result = MessageBox.Show(
            "Graphics contains unsaved bitmaps. Save them now?",
            "Unsaved Bitmaps",
            MessageBoxButtons.YesNoCancel
        );

        if (result == DialogResult.Cancel)
            return;
        if (result == DialogResult.Yes)
            SaveAllBitmaps();
    }

    try
    {
        using (Stream stream = file.OpenWrite())
        {
            DgtModel.Save(stream);
        }

        OnSaveSucceeded();
    }
    catch (IOException ex)
    {
        MessageBox.Show($"File save failed: {ex.Message}", "Error",
            MessageBoxButtons.OK, MessageBoxIcon.Error);
        LogError(ex);
    }
    finally
    {
        UpdateModifiedFlag(false);
    }
}

Error Handling Strategy:

1. Validation: Check preconditions before operations
2. User Notification: Clear, non-technical error messages
3. Logging: Comprehensive diagnostic logging to trace file

    public void Render(Graphics graphics)
    {
        if (!Visible || Layer != VisibleLayer)
            return;

        PrepareTransform(graphics); // Rotation, scaling
        RenderBackground(graphics); // Fill
        RenderContent(graphics);    // Widget-specific (abstract)
        RenderBorder(graphics);     // Outline

        DrawAxes(graphics);

        // Draw each pen series
        foreach (var pen in Pens)
        {
            if (pen.Data != null)
                DrawSeries(graphics, pen);

            using (var doc = new ActiveReport())
            {
                doc.LoadLayout(ReportTemplate.Stream);
                doc.Run();

                ExportToFormat(doc, dialog.FileName);

                MessageBox.Show($"Export to {Format} completed successfully.");
            }
        }
    }

    protected abstract string Format { get; }
    protected abstract void ExportToFormat(ActiveReport report, string filename);
}

// Specific export implementation
public class ExportToPDFCommand : AbstractExportToFileCommand
{
    protected override string Format => "PDF";

    protected override void ExportToFormat(ActiveReport report, string filename)
    {
        var pdf = new DataDynamics.ActiveReports.Export.Pdf.PdfExport();
