+# AC_Responder System - Toolbar Button Click Handling
+
+This document explains how toolbar button clicks are routed to responders in Toon Boom Harmony Premium and Storyboard Pro, and how to create custom responders to handle actions.
+
+**IDA Databases:**
+- `RE/ToonBoomActionManager.dll.i64` - AC_Manager and AC_Responder implementations
+- `RE/ToonBoomLayout.dll.i64` - Layout responder implementations
+- `RE/HarmonyPremium.exe.i64` - Application-specific responders
+
+## Overview
+
+Toon Boom uses a **Responder Chain** pattern (similar to macOS/Cocoa) for handling toolbar button clicks:
+
+1. **Toolbar XML** defines button items with a `responder` attribute and a `slot` attribute
+2. When clicked, `AC_Manager` looks up the responder by name
+3. The responder's slot is invoked via Qt's meta-object system
+4. If the responder doesn't handle it, the action propagates up the chain
+
+## Toolbar XML Structure
+
+From `toolbars.xml`:
+
+```xml
+<toolbar id="DrawingToolToolbar" text="Tools">
+  <!-- Simple item with responder and slot -->
+  <item 
+    checkable="true" 
+    icon="drawingtool/select.png" 
+    id="SelectTool" 
+    responder="sceneUI" 
+    slot="onActionChooseSelectToolInNormalMode()" 
+    text="Select" />
+  
+  <!-- Item with owner responder (view that owns the toolbar) -->
+  <item 
+    icon="library/refresh.png" 
+    id="LIBRARY_REFRESH" 
+    responder="owner" 
+    slot="onActionFolderRefresh()" 
+    text="Refresh" />
+    
+  <!-- Item with script execution -->
+  <item 
+    icon="script/createkeyframeson.png" 
+    id="CREATE_KEYFRAMES_ON" 
+    itemParameter="TB_CreateKeyFramesOn in TB_CreateKeyFramesOn.js" 
+    responder="scriptResponder" 
+    slot="onActionExecuteScript(QString)" 
+    text="Create Keyframes On" />
+</toolbar>
+```
+
+### Key XML Attributes
+
+| Attribute | Description |
+|-----------|-------------|
+| `id` | Unique identifier for the toolbar item |
+| `responder` | Name of the responder to handle clicks |
+| `slot` | Qt slot signature to invoke |
+| `icon` | Path to icon image |
+| `text` | Display text / tooltip |
+| `checkable` | If "true", button toggles on/off |
+| `condition` | Expression for conditional visibility |
+| `itemParameter` | Extra parameter passed to slot |
+| `shortcut` | Keyboard shortcut name |
+
+### Common Responder Names
+
+| Responder | Description |
+|-----------|-------------|
+| `owner` | The QObject that "owns" the toolbar (usually the view) |
+| `sceneUI` | Main scene UI responder (Harmony_SceneUI / SBoard_SceneUI) |
+| `scene` | Scene data responder |
+| `selection` | Selection responder (for cut/copy/paste) |
+| `timelineView` | Timeline view responder |
+| `xsheetView` | Xsheet view responder |
+| `onionSkinResponder` | Onion skin feature responder |
+| `scriptResponder` | Script execution responder |

+
+## The Responder Chain
+
+When a toolbar button is clicked:
+
+```
+┌─────────────────────────────────────────────────────────────────┐
+│ 1. User clicks toolbar button                                   │
+└─────────────────────────────────────────────────────────────────┘
+                              │
+                              ▼
+┌─────────────────────────────────────────────────────────────────┐
+│ 2. AC_ToolbarItemImpl triggers AC_ActionInfo                    │
+│    - Creates AC_ActionInfo with slot name, parameters           │
+│    - Gets responder name from XML attribute                     │
+└─────────────────────────────────────────────────────────────────┘
+                              │

+┌─────────────────────────────────────────────────────────────────┐
+│ 3. AC_Manager::responder(name) looks up responder               │
+│    - "owner" → toolbar's owner QObject cast to AC_Responder     │
+│    - other names → registered responder by identity             │
+└─────────────────────────────────────────────────────────────────┘
+                              │

+│ 4. AC_Responder::perform(AC_ActionInfo*) is called              │
+│    - Sets responder in action info                              │
+│    - Invokes slot via QMetaObject::invokeMethod                 │
+│    - Returns AC_Result (Handled, NotHandled, Error)             │
+└─────────────────────────────────────────────────────────────────┘
+                              │
+                              ▼
+┌─────────────────────────────────────────────────────────────────┐
+│ 5. If NotHandled, propagate up chain                            │
+│    - Try parent responder via parentResponder()                 │
+│    - Eventually reaches applicationResponder                    │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+## AC_Responder Interface
+
+The `AC_Responder` abstract interface defines how objects participate in the responder chain:
+
+```cpp
+class AC_Responder {
+public:
+    virtual ~AC_Responder() = 0;
+    
+    // Identity
+    virtual const QString& responderIdentity() const = 0;
+    virtual const QString& responderDescription() const = 0;
+    virtual void setResponderDescription(const QString& desc) = 0;
+    
+    // Chain navigation
+    virtual AC_Responder* parentResponder() = 0;
+    virtual AC_Responder* proxyResponder() = 0;
+    
+    // First responder status (keyboard focus)
+    virtual bool acceptsFirstResponder() = 0;
+    virtual bool becomeFirstResponder() = 0;
+    virtual bool resignFirstResponder() = 0;
+    
+    // Selection responder status
+    virtual bool acceptsSelectionResponder() = 0;
+    virtual bool becomeSelectionResponder() = 0;
+    virtual bool resignSelectionResponder() = 0;
+    
+    // Action handling
+    virtual AC_Result perform(AC_ActionInfo* info) = 0;
+    virtual AC_Result performDownToChildren(AC_ActionInfo* info) = 0;
+    virtual bool shouldReceiveMessages() const = 0;
+    virtual bool handleShortcuts() const = 0;
+    
+    // Event handling
+    virtual AC_Result handleEvent(QEvent* event) = 0;
+    
+    // Manager access
+    virtual AC_Manager* actionManager() const = 0;
+};
+```
+
+## AC_ResponderBase Helper Class
+
+The framework provides `AC_ResponderBase`, a concrete helper class that implements the `AC_Responder` interface with sensible defaults. This makes it easy to create custom responders without implementing every virtual method:
+
+```cpp
+// From ac_manager.hpp
+class AC_ResponderBase : public AC_Responder {
+public:
+    AC_ResponderBase(const QString& identity, AC_Manager* manager = nullptr,
+                     AC_Responder* parent = nullptr);
+    virtual ~AC_ResponderBase() = default;
+    
+    // Identity - stored internally
+    const QString& responderIdentity() const override;
+    const QString& responderDescription() const override;
+    void setResponderDescription(const QString& desc) override;
+    
+    // Chain - returns parent passed to constructor
+    AC_Responder* parentResponder() override;
+    AC_Responder* proxyResponder() override;  // returns nullptr
+    
+    // First responder - all return false by default
+    bool acceptsFirstResponder() override;
+    bool becomeFirstResponder() override;
+    bool resignFirstResponder() override;
+    
+    // Selection responder - all return false by default
+    bool acceptsSelectionResponder() override;
+    bool becomeSelectionResponder() override;
+    bool resignSelectionResponder() override;
+    
+    // Action handling - return NotHandled by default
+    AC_Result perform(AC_ActionInfo* info) override;
+    AC_Result performDownToChildren(AC_ActionInfo* info) override;
+    
+    // Message handling - return true by default
+    bool shouldReceiveMessages() const override;
+    bool handleShortcuts() const override;
+    
+    // Event handling - returns NotHandled
+    AC_Result handleEvent(QEvent* event) override;
+    
+    // Manager access
+    AC_Manager* actionManager() const override;
+    void setActionManager(AC_Manager* manager);
+
+protected:
+    QString m_identity;
+    QString m_description;
+    AC_Manager* m_manager;
+    AC_Responder* m_parentResponder;
+};
+```
+
+## Creating a Custom Responder
+
+### Method 1: Using AC_ResponderBase with QObject
+
+The simplest approach is to create a class that inherits from both `QObject` (for Qt slots) and `AC_ResponderBase` (for responder functionality):
+
+```cpp
+#include <toon_boom/ac_manager.hpp>
+
+class MyResponder : public QObject, public AC_ResponderBase {
+    Q_OBJECT
+    
+public:
+    MyResponder(const QString& identity, AC_Manager* manager, QObject* parent = nullptr)
+        : QObject(parent)
+        , AC_ResponderBase(identity, manager)
+    {
+        // Register with AC_Manager
+        manager->registerResponder(this, nullptr);
+    }
+    
+    ~MyResponder() {
+        if (AC_Manager* mgr = actionManager()) {
+            mgr->unregisterResponder(this);
+        }
+    }
+
+public slots:
+    // Slot that matches toolbar XML slot signature
+    void onActionMyCustomAction() {
+        qDebug() << "My custom action triggered!";
+    }
+    
+    void onActionWithParameter(const QString& param) {
+        qDebug() << "Action with parameter:" << param;
+    }
+    
+    // Validate slot - called before action to update enabled/checked state
+    void onActionMyCustomActionValidate(AC_ActionInfo* info) {
+        // Enable based on some condition
+        info->setEnabled(canPerformAction());
+        info->setChecked(isActionActive());
+    }
+    
+private:
+    bool canPerformAction() const { return true; }
+    bool isActionActive() const { return false; }
+};
+```
+
+### Method 2: Widget-Based Responder
+
+For a widget that also acts as a responder:
+
+```cpp
+#include <toon_boom/ac_manager.hpp>
+#include <QWidget>
+
+class MyCustomWidget : public QWidget, public AC_ResponderBase {
+    Q_OBJECT
+    
+public:
+    MyCustomWidget(const QString& identity, AC_Manager* manager, QWidget* parent = nullptr)
+        : QWidget(parent)
+        , AC_ResponderBase(identity, manager)
+    {
+        // Register with AC_Manager, passing 'this' as the associated widget
+        manager->registerResponder(this, this);
+    }
+    
+    ~MyCustomWidget() {
+        if (AC_Manager* mgr = actionManager()) {
+            mgr->unregisterResponder(this);
+        }
+    }
+
+public slots:
+    void onActionWidgetAction() {
+        qDebug() << "Widget action triggered!";
+    }
+    
+    void onActionWidgetActionValidate(AC_ActionInfo* info) {
+        info->setEnabled(isEnabled());
+    }
+};
+```
+
+### Method 3: Implementing AC_Responder Directly
+
+For full control over the responder interface:
+
+```cpp
+class MyFullResponder : public QObject, public AC_Responder {
+    Q_OBJECT
+    
+public:
+    MyFullResponder(const QString& identity, AC_Manager* manager)
+        : m_identity(identity), m_manager(manager)
+    {
+        manager->registerResponder(this, nullptr);
+    }
+    
+    // AC_Responder interface - implement all methods
+    const QString& responderIdentity() const override { return m_identity; }
+    const QString& responderDescription() const override { return m_description; }
+    void setResponderDescription(const QString& desc) override { m_description = desc; }
+    
+    AC_Responder* parentResponder() override { return nullptr; }
+    AC_Responder* proxyResponder() override { return nullptr; }
+    
+    bool acceptsFirstResponder() override { return false; }
+    bool becomeFirstResponder() override { return false; }
+    bool resignFirstResponder() override { return false; }
+    
+    bool acceptsSelectionResponder() override { return false; }
+    bool becomeSelectionResponder() override { return false; }
+    bool resignSelectionResponder() override { return false; }
+    
+    AC_Result perform(AC_ActionInfo* info) override {
+        // Use Qt meta-object to invoke the slot by name
+        // AC_ActionInfo contains slot name and parameters
+        return AC_Result::NotHandled;
+    }
+    
+    AC_Result performDownToChildren(AC_ActionInfo* info) override {
+        return AC_Result::NotHandled;
+    }
+    
+    bool shouldReceiveMessages() const override { return true; }
+    bool handleShortcuts() const override { return true; }
+    
+    AC_Result handleEvent(QEvent*) override { return AC_Result::NotHandled; }
+    
+    AC_Manager* actionManager() const override { return m_manager; }
+
+public slots:
+    void onActionDoSomething() {
+        // Handle the action
+    }
+
+private:
+    QString m_identity;
+    QString m_description;
+    AC_Manager* m_manager;
+};
+```
+
+## AC_ActionInfo Structure
+
+When an action is triggered, an `AC_ActionInfo` object is created:
+
+```cpp
+class AC_ActionInfo : public QObject {
+    // Key methods
+    const QString& slot() const;      // Slot signature to invoke
+    const QString& text() const;      // Action display text
+    QVariant itemParameter() const;   // Extra parameter from XML
+    
+    // State methods
+    bool isEnabled() const;
+    void setEnabled(bool enabled);
+    bool isChecked() const;
+    void setChecked(bool checked);
+    
+    // Responder info
+    AC_Responder* responder() const;
+    void setResponder(AC_Responder* resp);
+};
+```
+
+## Validation Pattern
+
+Before displaying a menu or when the UI updates, Toon Boom calls validation methods:
+
+1. For each toolbar item, look for a slot named `<slotName>Validate(AC_ActionInfo*)`
+2. If found, invoke it to update enabled/checked state
+3. Display the item according to the updated state
+
+Example from `TULayoutManager`:
+
+```cpp
+// Address: 0x7ffa0be52e60
+void TULayoutManager::onActionFullscreenValidate(AC_ActionInfo* info) {
+    info->setVisible(true);  // vtable[7]
+    info->setEnabled(true);  // AC_ActionData::setEnabled
+}
+```
+
+## Registration with AC_Manager
+
+Responders must be registered to be found by name:
+
+```cpp
+AC_Manager* manager = PLUG_Services::getActionManager();
+
+// Register a responder
+bool success = manager->registerResponder(myResponder, myWidget);
+
+// Unregister when done
+manager->unregisterResponder(myResponder);
+
+// Find a responder by identity
+AC_Responder* resp = manager->responder("myResponderIdentity");
+
+// Get responder for a widget
+AC_Responder* widgetResp = manager->responderForWidget(someWidget);
+```
+
+## Example: Adding a Custom Toolbar Button
+
+### Step 1: Define in XML (or load programmatically)
+
+```xml
+<toolbar id="MyToolbar" text="My Tools">
+  <item 
+    id="MyAction" 
+    icon="my/icon.png"
+    responder="myCustomResponder" 
+    slot="onActionMyAction()" 
+    text="My Action" />
+</toolbar>
+```
+
+### Step 2: Create and Register Responder
+
+```cpp
+class MyToolResponder : public QObject, public AC_ResponderBase {
+    Q_OBJECT
+    
+public:
+    MyToolResponder(AC_Manager* manager)
+        : QObject()
+        , AC_ResponderBase("myCustomResponder", manager)
+    {
+        manager->registerResponder(this, nullptr);
+    }
+    
+    ~MyToolResponder() {
+        if (AC_Manager* mgr = actionManager()) {
+            mgr->unregisterResponder(this);
+        }
+    }
+
+public slots:
+    void onActionMyAction() {
+        qDebug() << "My custom toolbar button clicked!";
+        // Do your custom action here
+    }
+    
+    void onActionMyActionValidate(AC_ActionInfo* info) {
+        info->setEnabled(true);
+    }
+};
+```
+
+### Step 3: Initialize
+
+```cpp
+void initializeMyToolbar() {
+    AC_Manager* manager = PLUG_Services::getActionManager();
+    
+    // Create and register responder
+    MyToolResponder* responder = new MyToolResponder(manager);
+    
+    // Load toolbar XML
+    QDomDocument doc;
+    doc.setContent(myToolbarXmlString);
+    QList<QString> ids;
+    manager->loadToolbars(doc.documentElement(), ids);
+    
+    // Show the toolbar
+    TULayoutManager* layoutManager = getLayoutManager();
+    layoutManager->showToolbar("MyToolbar", true);
+}
+```
+
+## Owner Responder Pattern
+
+When `responder="owner"` is used, the toolbar's owner QObject is used:
+
+```cpp
+// In AC_ToolbarImpl, owner is stored at offset +0xE0
+void AC_ToolbarImpl::setOwner(QObject* owner) {
+    m_owner = owner;
+    connect(owner, &QObject::destroyed, this, &AC_ToolbarImpl::ownerDestroyed);
+}
+
+// When resolving "owner" responder:
+if (responderName == "owner") {
+    QObject* owner = toolbar->owner();
+    return qobject_cast<AC_Responder*>(owner);
+}
+```
+
+This pattern is commonly used for view-specific toolbars where the view itself handles the actions.
+
+## Key Addresses
+
+### ToonBoomActionManager.dll
+| Symbol | Address | Description |
+|--------|---------|-------------|
+| AC_ManagerImpl::registerResponder | (via vtable) | Registers responder |
+| AC_ManagerImpl::unregisterResponder | (via vtable) | Unregisters responder |
+| AC_ManagerImpl::responder | (via vtable) | Finds responder by name |
+
+## Summary
+
+To respond to toolbar button clicks:
+
+1. **Create a class** that inherits from `QObject` and `AC_ResponderBase` (or implement `AC_Responder` directly)
+2. **Register** with `AC_Manager::registerResponder(responder, widget)`
+3. **Define slots** matching the toolbar XML `slot` attribute signatures
+4. **Optionally define validate slots** (`<slotName>Validate(AC_ActionInfo*)`) for state updates
+5. **Reference your responder** by identity in the toolbar XML `responder` attribute

+# TULayoutView Toolbar Integration in Toon Boom
+
+This document explains how toolbars are created, managed, and displayed within TULayoutView instances in Toon Boom Harmony Premium and Storyboard Pro.
+
+**IDA Databases:**
+- `RE/HarmonyPremium.exe.i64` - Main application
+- `RE/ToonBoomActionManager.dll.i64` - AC_Toolbar and AC_Manager implementations

+## Overview
+
+Toon Boom uses a two-tier toolbar system:
+
+1. **Global Toolbars** - Application-wide toolbars (FileToolbar, EditToolbar, DrawingToolToolbar, etc.)
+2. **View-Specific Toolbars** - Toolbars that appear when a specific view has focus (DrawingViewToolbar, TimelineViewToolbar, CameraViewToolbar, etc.)

+
+## Toolbar Definition and Creation Flow
+
+### 1. Toolbar XML Loading
+
+During application startup, toolbars are loaded from `toolbars.xml`:
+
+```cpp
+// From HarmonyPremium.exe session initialization (0x140034EB0)
+// Loads toolbars.xml via AC_Manager::addToolbarFromFile (vtable+376)
+
+UT_String toolbarsPath = RM_GetResourcePath("toolbars.xml");
+actionManager->addToolbarFromFile(toolbarsPath.ToQString(), &toolbarList);
+```
+
+The `toolbars.xml` file defines toolbar content using XML elements like:
+```xml
+<toolbar id="DrawingViewToolbar" trContext="Toolbars">
+    <item id="DrawingTool.Select" />
+    <separator />
+    <item id="DrawingTool.Brush" />
+    <!-- ... more items ... -->
+</toolbar>
+```
+
+### 2. Global Toolbar Initialization
+
+Global toolbars are shown during session initialization (`sub_14002F840`):
+
+```cpp
+// Show global toolbars via TULayoutManager::showToolbar (vtable+416)
+layoutManager->showToolbar("FileToolbar", true);
+layoutManager->showToolbar("EditToolbar", true);
+layoutManager->showToolbar("DrawingToolToolbar", true);
+layoutManager->showToolbar("ArtLayerToolbar", true);
+
+// Conditional toolbars based on features
+if (WHO_Features::hasOnionSkinToolbar()) {
+    layoutManager->showToolbar("OnionSkinToolbar", false, true, nullptr);
+}
+```
+
+**Key Function Addresses (HarmonyPremium.exe):**
+- Session toolbar init: `0x14002F840`
+- TULayoutManager::showToolbar import: `0x1409c8ea0`
+
+### 3. View-Specific Toolbar Definition
+
+Each view class overrides `TULayoutView::toolbar()` to return its toolbar definition:
+
+```cpp
+// Example: CameraView::toolbar() at 0x1403BC450
+QDomElement CameraView::toolbar() {
+    // Get AC_Manager from embedded context (offset -56 from TULayoutView*)
+    AC_Manager* manager = *(AC_Manager**)(this - 56);
+    if (manager) {
+        // Call AC_Manager::getToolbarElement (vtable+416 / offset 52*8)
+        QDomElement element;
+        manager->getToolbarElement(&element, "CameraViewToolbar");
+        return element;
+    }
+    return QDomElement(); // Empty if no manager
+}
+```
+
+**Known View Toolbar Implementations:**
+
+| View Class | Toolbar Name | Address |
+|------------|--------------|---------|
+| DrawingView | "DrawingViewToolbar" | `0x1403B9880` |
+| CameraView | "CameraViewToolbar" | `0x1403BC450` |
+| TimelineView | "TimelineViewToolbar" | `0x14011C5F0` |
+| SGV_Graph3DView | (custom impl) | `0x1409e1866` |
+
+### 4. Toolbar Display Flow
+
+When a view gains focus, the toolbar is displayed through this flow:
+
+```
+1. User clicks on a view widget
+           │
+           ▼
+2. Application event handler detects focus change
+   (sub_140059DE0 checks for TULayoutFrame inheritance)
+           │
+           ▼
+3. TULayoutManager::setCurrentLayoutFrame(frame)
+           │
+           ▼
+4. TULayoutFrame::showViewToolBar()
+   - Gets current view from view holder
+   - Calls view->toolbar() to get QDomElement
+   - Creates AC_ToolbarImpl from element
+   - Adds toolbar to TULayoutMainWindow
+           │
+           ▼
+5. Toolbar becomes visible in frame's toolbar area
+```
+
+## AC_Toolbar Integration
+
+### AC_Manager Methods Used
+
+The AC_Manager provides these key toolbar methods:
+
+| Method | Vtable Offset | Description |
+|--------|---------------|-------------|
+| `getToolbarElement` | +416 (52*8) | Returns QDomElement for toolbar by name |
+| `addToolbarFromFile` | +376 (47*8) | Loads toolbar definitions from XML file |
+| `createToolbar` | +368 (46*8) | Creates AC_ToolbarImpl from element |
+
+### AC_ToolbarImpl Creation
+
+When `TULayoutFrame::showViewToolBar()` needs to display a toolbar:
+
+```cpp
+// Pseudocode for toolbar creation
+void TULayoutFrame::showViewToolBar() {
+    TULayoutView* view = getCurrentView();
+    if (!view) return;
+    
+    // Get toolbar XML element from view
+    QDomElement toolbarElement = view->toolbar();
+    if (toolbarElement.isNull()) return;
+    
+    // Create AC_ToolbarImpl via AC_Manager
+    AC_Toolbar* toolbar = m_actionManager->createToolbar(
+        this,                    // owner
+        toolbarElement.attribute("text"),
+        m_mainWindow,            // parent QMainWindow
+        toolbarElement.attribute("id").toUtf8().constData(),
+        toolbarElement,
+        nullptr                  // default config
+    );
+    
+    // Add to frame's main window
+    m_mainWindow->addToolBar(Qt::TopToolBarArea, toolbar->toQToolBar());
+    
+    // Store for later removal
+    m_viewToolbar = toolbar;
+}
+```
+
+### LAY_ToolbarInfo Configuration
+
+Each view can have stored toolbar configuration via `LAY_ToolbarInfo`:
+
+```cpp
+// Structure of LAY_ToolbarInfo (104 bytes)
+class LAY_ToolbarInfo {
+    int m_x;                              // +0x00 - X position
+    int m_y;                              // +0x04 - Y position  
+    int m_index;                          // +0x08 - Toolbar index
+    int m_width;                          // +0x0C - Width
+    int m_height;                         // +0x10 - Height
+    bool m_newline;                       // +0x14 - Break to new line
+    bool m_visible;                       // +0x15 - Visibility
+    bool m_isDefault;                     // +0x16 - Using default config
+    QString m_name;                       // +0x18 - Toolbar name
+    Qt::Orientation m_orientation;        // +0x30 - Horizontal/Vertical
+    Qt::ToolBarArea m_toolBarArea;        // +0x34 - Docking area
+    QList<QString> m_buttonConfig;        // +0x38 - Current button order
+    QList<QString> m_buttonDefaultConfig; // +0x50 - Default button order
+};
+```
+
+The view receives its toolbar info via `TULayoutView::setToolbarInfo()`:
+- Import: `0x1409c8f4e` (thunk to ToonBoomLayout.dll)
+- Called by TULayoutFrame when loading saved layout preferences
+
+## Implementing Custom View Toolbars
+
+### Step 1: Define Toolbar in XML
+
+Create a toolbar definition that will be loaded by AC_Manager:
+
+```xml
+<toolbar id="MyCustomViewToolbar" trContext="MyToolbars">
+    <item id="MyResponder.Action1" />
+    <item id="MyResponder.Action2" />
+    <separator />
+    <placeholder id="CustomItems" />
+</toolbar>
+```
+
+### Step 2: Override toolbar() in Your View
+
+```cpp
+class MyCustomView : public TULayoutView {
+public:
+    QDomElement toolbar() override {
+        // Get AC_Manager - depends on your view's structure
+        // For TUWidgetLayoutView subclasses, manager is at offset -56
+        AC_Manager* manager = getActionManager();
+        if (!manager) {
+            return QDomElement();
+        }
+        
+        // Use AC_Manager to get toolbar element by name
+        QDomElement element;
+        // Call via vtable[52] - getToolbarElement
+        auto getToolbarElement = reinterpret_cast<void(*)(AC_Manager*, QDomElement*, const QString&)>(
+            (*reinterpret_cast<void***>(manager))[52]
+        );
+        
+        QString toolbarName("MyCustomViewToolbar");
+        getToolbarElement(manager, &element, toolbarName);
+        
+        return element;
+    }
+};
+```
+
+### Step 3: Register Toolbar XML
+
+Ensure your toolbar XML is loaded during initialization:
+
+```cpp
+// Option 1: Add to existing toolbars.xml (if modifying installation)
+
+// Option 2: Load programmatically
+AC_Manager* manager = PLUG_Services::getActionManager();
+if (manager) {
+    // Use addToolbarFromElement (vtable+376)
+    QDomDocument doc;
+    doc.setContent(myToolbarXml);
+    QDomElement element = doc.documentElement();
+    
+    // Call via vtable
+    auto addToolbarFromElement = reinterpret_cast<void(*)(AC_Manager*, const QDomElement&, const QString&, bool)>(
+        (*reinterpret_cast<void***>(manager))[47]
+    );
+    addToolbarFromElement(manager, element, "MyCustomViewToolbar", false);
+}
+```

+# TUWidgetLayoutView Class Analysis
+
+This document contains the reverse engineering analysis of the `TUWidgetLayoutView` class from `ToonBoomLayout.dll` used in Toon Boom Harmony Premium and Storyboard Pro.
+
+## Overview
+
+`TUWidgetLayoutView` is a concrete implementation that combines:
+- **QWidget** - for Qt UI rendering
+- **AC_ResponderTemplateWidget<QWidget>** - for action/responder chain handling  
+- **TULayoutView** - for the Toon Boom layout system integration
+
+This class serves as the base for most view types in Toon Boom's panel/window system.
+
+## Class Hierarchy
+
+```
+QObject
+└── QWidget
+    └── AC_ResponderTemplateWidget<QWidget>
+        └── TUWidgetLayoutView
+            └── [TULayoutView embedded at offset +104]
+```
+
+Note: `TULayoutView` is not a base class in the C++ inheritance sense but is **embedded** as a sub-object at offset +104. This is a form of composition that allows `TULayoutView` to have its own vtable and virtual methods.
+
+## Memory Layout (x64 MSVC)
+
+| Offset (hex) | Offset (dec) | Size | Member |
+|--------------|--------------|------|--------|
+| +0x00 | +0 | 8 | vptr (QObject) |
+| +0x08 | +8 | 8 | QObjectData* d_ptr |
+| +0x10 | +16 | 8 | vptr (QPaintDevice) |
+| +0x18 | +24 | 16 | QWidget internal data |
+| +0x28 | +40 | 8 | vptr (AC_ResponderTemplateWidget<QWidget>) |
+| +0x30 | +48 | 8 | AC_Manager* m_actionManager |
+| +0x38 | +56 | 24 | QString m_responderIdentity |
+| +0x50 | +80 | 24 | QString m_responderDescription |
+| **+0x68** | **+104** | 8 | **vptr (TULayoutView)** - TULayoutView starts here |
+| +0x70 | +112 | 24 | QString m_internalName (TULayoutView) |

+| +0x108 | +264 | 24 | QString m_caption (TULayoutView) |
+
+**Total size: 0x120 (288 bytes)**
+
+## VTable Structure

+Contains all QObject and QWidget virtual methods including:
+- `metaObject()`, `qt_metacast()`, `qt_metacall()`
+- `event()`, `eventFilter()`
+- `paintEvent()`, `mousePressEvent()`, etc.

+
+## Key Methods
+
+### Constructor
+```cpp
+TUWidgetLayoutView(
+    AC_Manager* manager,         // Action manager (stored at +0x30)
+    const QString& objectName,   // Qt object name
+    QWidget* parent,             // Parent widget
+    const char* className,       // Class name string
+    Qt::WindowFlags flags        // Window flags
+)
+```
+
+**Construction sequence:**
+1. Call `AC_ResponderTemplateWidget<QWidget>` ctor with (parent, flags, objectName)
+2. Call `TULayoutView` default ctor at `this + 104`
+3. Install all 4 TUWidgetLayoutView vtables
+4. Set minimum width to 150 pixels
+5. If parent != nullptr && manager != nullptr:
+   - Call `initActionManager(manager)` 
+6. Else:
+   - Store manager directly at offset +0x30
+
+### Destructor
+**Destruction sequence:**
+1. Reset vtables to TUWidgetLayoutView vtables
+2. Destroy `TULayoutView::m_caption` (QString at +0x108)
+3. Destroy `TULayoutView::m_toolbarInfo` (LAY_ToolbarInfo at +0x88)
+4. Destroy `TULayoutView::m_internalName` (QString at +0x70)
+5. Jump to `AC_ResponderTemplateWidget<QWidget>::~AC_ResponderTemplateWidget`
+
+### getWidget()
+```cpp
+QWidget* getWidget() {
+    return reinterpret_cast<QWidget*>(
+        reinterpret_cast<char*>(this) - 104);
+}
+```
+Called from TULayoutView* context (at +104), returns the containing QWidget* (at +0).
+
+### triggerMenuChanged()
+```cpp
+void triggerMenuChanged() {
+    // 'this' is TULayoutView* at +104
+    // Emit signal on containing TUWidgetLayoutView (this - 104)
+    TUWidgetLayoutView* widget = (TUWidgetLayoutView*)((char*)this - 104);
+    widget->menuChanged();
+}
+```
+
+### mousePressEvent()
+```cpp
+void mousePressEvent(QMouseEvent* event) {
+    QWidget::mousePressEvent(event);
+    if (!event->isAccepted()) {
+        event->accept();
+        setFocus(Qt::MouseFocusReason);  // Focus reason = 7
+    }
+}
+```
+
+## Qt Meta-Object System
+
+TUWidgetLayoutView participates in the Qt meta-object system:
+
+- `staticMetaObject` - Static meta-object for the class
+- `metaObject()` - Returns `&staticMetaObject` (or dynamic for QML)
+- `qt_metacast(const char* className)`:
+  - "TUWidgetLayoutView" → returns `this`
+  - "TULayoutView" → returns `this + 104`
+  - Otherwise → delegates to AC_ResponderTemplateWidget<QWidget>::qt_metacast
+- `tr()` - Static translation method
+
+### Signals
+- `menuChanged()` - Emitted when view menu changes (slot 0 in staticMetaObject signals)
+
+## Exported Symbols
+
+From ToonBoomLayout.dll:
+
+| Symbol | Description |
+|--------|-------------|
+| `??0TUWidgetLayoutView@@QEAA@...@Z` | Constructor |
+| `??1TUWidgetLayoutView@@UEAA@XZ` | Destructor |
+| `?getWidget@TUWidgetLayoutView@@UEAAPEAVQWidget@@XZ` | Non-const getWidget |
+| `?getWidget@TUWidgetLayoutView@@UEBAPEBVQWidget@@XZ` | Const getWidget |

+| `?menuChanged@TUWidgetLayoutView@@QEAAXXZ` | Signal implementation |
+| `?metaObject@TUWidgetLayoutView@@UEBAPEBUQMetaObject@@XZ` | Meta-object |
+| `?qt_metacast@TUWidgetLayoutView@@UEAAPEAXPEBD@Z` | Runtime cast |
+| `?qt_metacall@TUWidgetLayoutView@@UEAAHW4Call@QMetaObject@@HPEAPEAX@Z` | Meta-call |
+| `?qt_static_metacall@TUWidgetLayoutView@@...@Z` | Static meta-call |
+| `?tr@TUWidgetLayoutView@@SA?AVQString@@PEBD0H@Z` | Translation |
+
+## Helper Functions
+
+The header provides inline helper functions for pointer conversion:
+
+```cpp
+// Get TULayoutView* from TUWidgetLayoutView*
+TULayoutView* TUWidgetLayoutView_getLayoutView(TUWidgetLayoutView* widget);
+
+// Get TUWidgetLayoutView* from TULayoutView* (must be embedded in TUWidgetLayoutView)
+TUWidgetLayoutView* TULayoutView_getWidgetLayoutView(TULayoutView* view);
+
+// Get QWidget* from TUWidgetLayoutView* (same address, different type)
+QWidget* TUWidgetLayoutView_getWidget(TUWidgetLayoutView* widget);
+
+// Get AC_Manager* from TULayoutView* embedded in TUWidgetLayoutView
+AC_Manager* TULayoutView_getActionManager(TULayoutView* view);
+```
+
+## Subclasses
+
+Several classes in ToonBoomLayout.dll inherit from TUWidgetLayoutView:
+
+- `TUCanvasViewLayoutView` - Canvas/drawing view
+- `TUFrameLayoutView` - Frame view
+- `TUScrollViewLayoutView` - Scrollable view
+- `TUTextEditLayoutView` - Text editing view  
+- `TUVBoxLayoutView` - Vertical box layout view
+
+These share the same `getWidget()` implementation (returning `this - 104`).
+
+## Analysis Methodology
+
+This analysis was performed using:
+1. IDA Pro decompilation of constructor (`0x7ffa0be600a0`) and destructor (`0x7ffa0be60480`)
+2. Disassembly verification of exact byte offsets
+3. Cross-reference analysis of vtable addresses
+4. Examination of related methods (getWidget, triggerMenuChanged, etc.)
+5. Qt meta-object method analysis (qt_metacast, etc.)

+
+### Interface Pointers
+When you have an `AC_Toolbar*`:
+- `QToolBar*` = `(char*)this - 128`
+- `AC_ContainerImpl*` = `(char*)this - 88`
+- Identity QString is at `(char*)this - 72`
+
+### Key Methods
+
+#### Item Management
+- `insert(beforeObject, element)` - Insert item from XML
+- `insertAtPlaceholder(placeholder, element)` - Insert at named placeholder
+- `insertSeparator(beforeObject)` - Insert separator
+- `removeObject(identity)` - Remove item by identity
+- `clear()` - Remove all items
+
+#### Configuration
+- `config()` - Get current item order as QList<QString>
+- `setConfig(list)` - Restore from saved configuration
+- `defaultConfig()` - Get default item order
+- `isDefaultConfig()` - Check if current matches default
+
+#### Validation
+- `validateContent()` - Update enabled/checked states
+- `validateContentIfVisible()` - Only validate if toolbar is shown
+- `updateSeparators()` - Hide separators adjacent to hidden items
+
+### Signals
+```cpp
+void customized(QString identity);

+## Enumerations
+
+### AC_Result
+```cpp
+enum class AC_Result : int {
+    NotHandled = 0,  // Action not handled by any responder
+    Handled = 1,     // Action handled successfully
+    Error = 2        // Error during handling
+};
+```
+
+### AC_ManagerOption
+```cpp
+enum class AC_ManagerOption : int {
+    TrimShortcuts = 0  // Whether to trim whitespace from shortcuts
+};
+```
+
+### AC_Help::cshHelpType
+```cpp
+enum cshHelpType {
+    Type0 = 0,
+    Type1 = 1,
+    Type2 = 2,
+    Type3 = 3,
+    Type4 = 4,

+## XML Element Types
+
+AC_ToolbarImpl::insert() handles these XML element types:
+
+| Tag Name | Handler | Creates |
+|----------|---------|---------|
+| `item` | sub_1800363E0 | AC_ToolbarItemImpl |
+| `menu` | sub_1800363E0 | AC_ToolbarItemImpl (menu button) |
+| `multibutton` | sub_180037F30 | AC_ToolbarMultiButtonImpl |
+| `combobox` | sub_1800395D0 | AC_ToolbarComboBox |
+| `placeholder` | sub_18001B9F0 | Placeholder object |
+| `separator` | sub_18003ABD0 | AC_ToolbarSeparatorImpl |
+
+---
+
+## Usage Patterns
+
+### Getting AC_Manager Instance
+```cpp
+// Via PLUG_Services (from ToonBoomPlugInManager.dll)
+AC_Manager* manager = PLUG_Services::getActionManager();
+```
+
+### Creating a Toolbar
+```cpp
+QList<QString> ids;
+AC_Toolbar* toolbar = manager->createToolbar(
+    xmlElement,        // QDomElement with toolbar definition
+    &ids,              // Output: list of created item IDs
+    mainWindow,        // QMainWindow to attach to
+    Qt::TopToolBarArea,// Toolbar area
+    "myToolbar",       // Object name
+    owner              // Owner QObject for cleanup
+);
+```
+
+### Triggering an Action
+```cpp
+AC_Result result = manager->trigger(
+    "NetworkView",     // Responder identity
+    "onActionZoomIn",  // Action/slot name
+    false              // Don't iterate all responders
+);
+```
+
+### Validating an Action
+```cpp
+bool enabled, checked;
+manager->performValidation("NetworkView", "onActionZoomIn", &enabled, &checked);
+```
