These actions are triggered by user inputs (e.g., key presses, mouse clicks) or programmatically, enabling consistent view interactions. ### Key Components - **Command Enum**: Defines actions like `Select` (state change or interaction preparation), `Accept` (action confirmation), `HotKey` (hotkey activation), and others (e.g., `StartOfPage` for navigation). - **Command Handlers**: Views register handlers using `View.AddCommand`, specifying a `CommandImplementation` delegate that returns `bool?` (`null`: no command executed; `false`: executed but not handled; `true`: handled or canceled). - **Command Routing**: Commands are invoked via `View.InvokeCommand`, executing the handler or raising `CommandNotBound` if no handler exists. -- **Cancellable Work Pattern**: Command execution uses events (e.g., `Selecting`, `Accepting`) and virtual methods (e.g., `OnSelecting`, `OnAccepting`) for modification or cancellation, with `Cancel` indicating processing should stop. +- **Cancellable Work Pattern**: Command execution uses events (e.g., `Activating`, `Accepting`) and virtual methods (e.g., `OnActivating`, `OnAccepting`) for modification or cancellation, with `Cancel` indicating processing should stop. ### Role in Terminal.Gui The `Command` system bridges user input and view behavior, enabling: @@ -43,9 +43,9 @@ Views register commands using `View.AddCommand`, associating a `Command` with a private void SetupCommands() { AddCommand(Command.Accept, RaiseAccepting); - AddCommand(Command.Select, ctx => + AddCommand(Command.Activate, ctx => { - if (RaiseSelecting(ctx) is true) + if (RaiseActivating(ctx) is true) { return true; } @@ -88,8 +88,8 @@ public bool?

A generic propagation model would enhance flexibility for hierarchical components, but it must ensure that subviews (e.g., `MenuItemv2`) remain decoupled from superviews (e.g., `MenuBarv2`) to avoid implementation-specific dependencies. The current lack of propagation is a limitation, particularly for menus, but adding it requires careful design to avoid overcomplicating the API or impacting performance for views that don’t need it. -**Recommendation**: Maintain the local handling of `Command.Select` for now, as it meets the needs of most views like `CheckBox`, `FlagSelector`, and `ListView`. For `MenuBarv2`, continue using `SelectedMenuItemChanged` as a temporary solution, but prioritize developing a generic propagation mechanism that supports hierarchical coordination without coupling subviews to superviews. This mechanism should allow superviews to opt-in to receiving `Selecting` events from subviews, ensuring encapsulation (see appendix for a proposed solution). +**Recommendation**: Maintain the local handling of `Command.Activate` for now, as it meets the needs of most views like `CheckBox`, `FlagSelector`, and `ListView`.

For instance: - - `Menuv2`: “`Selecting` focuses a `MenuItemv2` via arrow keys, while `Accepting` executes the selected command.” - - `CheckBox`: “`Selecting` toggles the `CheckedState`, while `Accepting` confirms the current state.” - - `FlagSelector`: “`Selecting` toggles a subview flag, while `Accepting` confirms the entire flag set.” + - `Menuv2`: “`Activating` focuses a `MenuItemv2` via arrow keys, while `Accepting` executes the selected command.” + - `CheckBox`: “`Activating` toggles the `CheckedState`, while `Accepting` confirms the current state.” + - `FlagSelector`: “`Activating` toggles a subview flag, while `Accepting` confirms the entire flag set.” - Document the `Cancel` property’s role in `CommandEventArgs`, noting its current limitation (implying negation rather than completion) and the planned replacement with `Handled` to align with input events like `Key.Handled`. 2. **Address FlagSelector Design Flaw**: - - Refactor `FlagSelector`’s `CheckBox.Selecting` handler to separate `Selecting` and `Accepting` actions, ensuring `Selecting` is limited to subview state changes (toggling flags) and `Accepting` is reserved for parent-level confirmation of the `Value`. This resolves the conflation issue where subview `Selecting` incorrectly triggers `Accepting`. + - Refactor `FlagSelector`’s `CheckBox.Activating` handler to separate `Activating` and `Accepting` actions, ensuring `Activating` is limited to subview state changes (toggling flags) and `Accepting` is reserved for parent-level confirmation of the `Value`.

This enables more informed event handlers without requiring view-specific subscriptions. @@ -588,34 +588,34 @@ Based on the analysis of the current `Command` and `View.Command` system, as imp object?

The `Activating`/`Accepting` distinction is clear in principle but requires careful documentation to avoid confusion, particularly for stateless views where `Activating` is focus-driven and for views like `FlagSelector` where implementation flaws conflate the two concepts. View-specific events like `SelectedMenuItemChanged`, `CheckedStateChanged`, and `ValueChanged` are sufficient for post-selection notifications, negating the need for a generic `Selected` event. The `Accepted` event is valuable in hierarchical views like `Menuv2` and `MenuBarv2` but not universally required, suggesting inclusion in `Bar` or `Toplevel` rather than `View`.

TableView (TableView.cs) +- **Inconsistency in Command Purpose**: `Command.Accept` triggers `OnCellActivated`, suggesting a final action, but is bound to `CellActivationKey` and other custom keys, implying activation rather than acceptance. `Command.Activate` is associated with toggling selection, but `Key.Space` is bound to `Command.Activate` for toggling in related classes, blurring the distinction between activation and state change. +- **Key Binding Discrepancy**: Unlike default `View` bindings (`Space` for `Activate`, `Enter` for `Accept`), custom keys are used for `Accept`, disrupting the expected user interaction model. +- **Task**: **Task 1 - Standardize Command Purpose and Bindings in TableView**: Review and revise `TableView` to align `Command.Accept` with confirmation actions (e.g., finalizing cell selection) and `Command.Activate` with initial interaction (e.g., toggling or focusing). Ensure key bindings match default `View` expectations (`Space` for `Activate`, `Enter` for `Accept`) unless a specific use case justifies deviation. + +### 2. TreeView (TreeView.cs) +- **Inconsistency in Command Handling**: Both `Command.Accept` and `Command.Activate` are bound to the same method `ActivateSelectedObjectIfAny`, eliminating the distinction between initiating and finalizing an action, contrary to the `View` model. +- **Key Binding Discrepancy**: Only `ObjectActivationKey` is bound to `Command.Activate`, with no explicit binding for `Command.Accept`, suggesting `Accept` might not be directly accessible via a standard key. +- **Task**: **Task 2 - Differentiate Command Handling in TreeView**: Modify `TreeView` to separate `Command.Activate` for initial selection or focus and `Command.Accept` for confirmation of the selected node. Add standard key binding for `Command.Accept` (e.g., `Enter`) to ensure accessibility. + +### 3. MenuItemv2 and MenuBarv2 (Menuv2.cs, Menuv1/MenuItem.cs, Menuv1/MenuBar.cs) +- **Inconsistency in Command Purpose**: In `Menuv2.cs`, `Command.Accept` propagates to `SuperMenuItem`, aligning with hierarchical acceptance. In `MenuItem.cs` (v1), `Command.Activate` is used for selection with no clear `Accept` handling. In `MenuBar.cs` (v1), `Command.Accept` is bound to `Key.CursorDown`, which is atypical for a confirmation action. +- **Key Binding Discrepancy**: Binding `Accept` to navigation keys deviates from the standard confirmation role of `Accept`. `Activate` often triggers selection without a separate `Accept` step. +- **Task**: **Task 3 - Harmonize Command Usage in Menu Classes**: Ensure `Command.Activate` is used for focusing or selecting menu items and `Command.Accept` for executing the selected action across all menu-related classes. Standardize key bindings to use `Enter` for `Accept` and navigation keys or `Space` for `Activate`. + +### 4. PopoverMenu (PopoverMenu.cs) +- **Inconsistency in Command Handling**: Focuses on `Command.Accept` for menu closure without a clear `Command.Activate` phase.

Add appropriate key bindings (`Space` for `Activate`, `Enter` for `Accept`). + +### 5. Shortcut (Shortcut.cs) +- **Inconsistency in Command Handling**: Both `Command.Accept` and `Command.Activate` are bound to `DispatchCommand`, erasing the distinction between initiating and finalizing an action. +- **Invocation Discrepancy**: Multiple direct invocations of `Command.Activate` exist, but `Accept` is bound to the same action, indicating redundancy. +- **Task**: **Task 5 - Separate Command Roles in Shortcut**: Redefine `Command.Activate` to handle initial interaction (e.g., focus or preparation) and `Command.Accept` to execute the shortcut action, ensuring distinct roles and reducing redundancy in command invocation. + +### 6. Bar (Bar.cs) +- **Inconsistency in Command Handling**: No explicit binding or handling of `Command.Accept` or `Command.Activate`. Relies on contained `Shortcut` objects, which themselves handle commands inconsistently. +- **Key Binding Discrepancy**: No direct key bindings for commands, delegating to sub-views. +- **Task**: **Task 6 - Add Direct Command Handling in Bar**: Implement direct handling of `Command.Activate` and `Command.Accept` in `Bar` for focus or selection of contained items and confirmation actions, respectively.

Similarly, in `Menuv2`, navigation (e.g., arrow keys) triggers `Activating`, while Enter triggers `Accepting`, but the overlap in user intent can blur the lines. -- **Stateless Views**: For views like `Button` or `MenuItemv2`, `Activating` is limited to setting focus, which dilutes its purpose as a state-changing action and may confuse developers expecting a more substantial state change. -- **Propagation Limitations**: The local handling of `Command.Activate` restricts hierarchical coordination. For example, `MenuBarv2` relies on `SelectedMenuItemChanged` to manage `PopoverMenu` visibility, which is view-specific and not generalizable. This highlights a need for a propagation mechanism that maintains subview-superview decoupling. -- **FlagSelector Design Flaw**: In `FlagSelector`, the `CheckBox.Activating` handler incorrectly triggers both `Activating` and `Accepting`, conflating state changes (toggling flags) with action confirmation (submitting the flag set).

For instance: - - `Menuv2`: “`Activating` focuses a `MenuItemv2` via arrow keys, while `Accepting` executes the selected command.” - - `CheckBox`: “`Activating` toggles the `CheckedState`, while `Accepting` confirms the current state.” - - `FlagSelector`: “`Activating` toggles a subview flag, while `Accepting` confirms the entire flag set.” - - Document the `Cancel` property’s role in `CommandEventArgs`, noting its current limitation (implying negation rather than completion) and the planned replacement with `Handled` to align with input events like `Key.Handled`. - -2. **Address FlagSelector Design Flaw**: - - Refactor `FlagSelector`’s `CheckBox.Activating` handler to separate `Activating` and `Accepting` actions, ensuring `Activating` is limited to subview state changes (toggling flags) and `Accepting` is reserved for parent-level confirmation of the `Value`.

This enables more informed event handlers without requiring view-specific subscriptions. - - Proposed interface update: - ```csharp - public interface ICommandContext - { - Command Command { get; } - View?

The current reliance on `SelectedMenuItemChanged` is effective but view-specific, limiting reusability. - - Develop a propagation mechanism that allows superviews to opt-in to receiving `Activating` events from subviews without requiring subviews to know superview details, ensuring encapsulation. This could involve a new event or property in `View` to enable propagation while maintaining decoupling (see appendix for a proposed solution). - - Example: For `MenuBarv2`, a propagation mechanism could allow it to handle `Activating` events from `MenuItemv2` subviews to show or hide popovers, replacing the need for `SelectedMenuItemChanged`: - ```csharp - // Current workaround in MenuBarv2 - protected override void OnSelectedMenuItemChanged(MenuItemv2? selected) - { - if (IsOpen() && selected is MenuBarItemv2 { PopoverMenuOpen: false } selectedMenuBarItem) - { - ShowItem(selectedMenuBarItem); - } - } - ``` + - Develop a propagation mechanism for `Command.Activate` that allows superviews to opt-in to receiving events from subviews, ensuring encapsulation and addressing needs in hierarchical components. 6. **Standardize Hierarchical Handling for Accepting**: - - Refine the propagation model for `Command.Accept` to reduce reliance on view-specific logic, such as `Menuv2`’s use of `SuperMenuItem` for submenu propagation. The current approach, while functional, introduces coupling: - ```csharp - if (SuperView is null && SuperMenuItem is {}) - { - return SuperMenuItem?.InvokeCommand(Command.Accept, args.Context) is true; - } - ``` - - Explore a more generic mechanism, such as allowing superviews to subscribe to `Accepting` events from subviews, to streamline propagation and improve encapsulation. This could be addressed in conjunction with `Activating` propagation (see appendix). - - Example: In `Menuv2`, a subscription-based model could replace `SuperMenuItem` logic: - ```csharp - // Hypothetical subscription in Menuv2 - SubViewAdded += (sender, args) => - { - if (args.View is MenuItemv2 menuItem) - { - menuItem.Accepting += (s, e) => RaiseAccepting(e.Context); - } - }; - ``` + - Refine the propagation model for `Command.Accept` to reduce reliance on view-specific logic, streamlining propagation and improving encapsulation. ## Conclusion -The `Command` and `View.Command` system in Terminal.Gui provides a robust framework for handling view actions, with `Activating` and `Accepting` serving as opinionated mechanisms for state changes/preparation and action confirmations. The system is effectively implemented across `Menuv2`, `MenuBarv2`, `CheckBox`, and `FlagSelector`, supporting a range of stateful and stateless interactions.

These changes are not yet implemented but aim to improve clarity, consistency, and flexibility. ### Proposed Changes -1. **Rename `Command.Activate` to `Command.Activate`**: - - Replace `Command.Activate`, `Activating` event, `OnActivating`, and `RaiseActivating` with `Command.Activate`, `Activating`, `OnActivating`, and `RaiseActivating`. - - Rationale: “Select” is ambiguous for stateless views (e.g., `Button` focus) and imprecise for non-list state changes (e.g., `CheckBox` toggling). “Activate” better captures state changes and preparation. - - Impact: Breaking change requiring codebase updates and migration guidance. -2. **Replace `Cancel` with `Handled` in `CommandEventArgs`**: - - Replace `Cancel` with `Handled` to indicate command completion, aligning with `Key.Handled` (issue #3913). - - Rationale: `Cancel` implies negation, not completion. - - Impact: Clarifies semantics, requires updating event handlers. - -3. **Introduce `PropagateActivating` Event**: +1. **Introduce `PropagateActivating` Event**: - Add `event EventHandler? PropagateActivating` to `View`, allowing superviews (e.g., `MenuBarv2`) to subscribe to subview propagation requests. - Rationale: Enables hierarchical coordination (e.g., `MenuBarv2` managing `PopoverMenu` visibility) without coupling subviews to superviews, addressing the current reliance on view-specific events like `SelectedMenuItemChanged`. - Impact: Enhances flexibility for hierarchical views, requires subscription management in superviews like `MenuBarv2`. - -### Benefits -- **Clarity**: `Activate` improves terminology for all views. -- **Consistency**: `Handled` aligns with input events. -- **Decoupling**: `PropagateActivating` supports hierarchical needs without subview-superview dependencies. -- **Extensibility**: Applicable to other hierarchies (e.g., dialogs, `TabView`). - -### Implementation Notes -- Update `Command` enum, `View`, and derived classes for the rename. -- Modify `CommandEventArgs` for `Handled`. -- Implement `PropagateActivating` and test in `MenuBarv2`. -- Revise documentation to reflect changes. - -For details, refer to the filed issue in the Terminal.Gui repository. \ No newline at end of file From 4d685aa60be1de2c2d5fd5327a657fee98e3f69b Mon Sep 17 00:00:00 2001 From: Tig Date: Thu, 5 Jun 2025 12:35:46 -0600 Subject: [PATCH 19/89] Fixes #4122 Updated `PopoverBaseImpl.cs` to clarify mouse event handling in popovers. Modified `View.Layout.cs` to adjust view count checks for active popovers. Corrected documentation in `ViewportSettingsFlags.cs` regarding the `TransparentMouse` flag. Added a new test method in `ApplicationPopoverTests.cs` to validate view retrieval under mouse coordinates when a popover is active, with multiple test cases included.

It critically evaluates the current state of these commands across various `View` sub-classes, documenting inconsistencies in their usage as tasks to be addressed. The document reflects the current implementation as observed in the codebase, including the `Cancel` property in `CommandEventArgs` and local handling of `Command.Activate`. An appendix briefly summarizes proposed changes from a filed issue to rename `Command.Activate`, replace `Cancel` with `Handled`, and introduce a propagation mechanism, addressing limitations in the current system. +Central to this system are the `Activating` and `Accepting` events, which encapsulate common user interactions: `Activating` for changing a view's state or preparing it for interaction (e.g., toggling a checkbox, focusing a menu item), and `Accepting` for confirming an action or state (e.g., executing a menu command, submitting a dialog). ## Overview of the Command System -The `Command` system in Terminal.Gui defines a set of standard actions via the `Command` enum (e.g., `Command.Activate`, `Command.Accept`, `Command.HotKey`, `Command.StartOfPage`). These actions are triggered by user inputs (e.g., key presses, mouse clicks) or programmatically, enabling consistent view interactions. +The `Command` system in Terminal.Gui defines a set of standard actions via the `Command` enum (e.g., `Command.Activate`, `Command.Accept`, `Command.HotKey`, `Command.StartOfPage`). These actions are triggered by user inputs (e.g., by default, `Key.Space` and `MouseFlags.Button1Clicked` are bound to `Command.Activate`, while `Key.Enter` is bound to `Command.Accept`). ### Key Components + - **Command Enum**: Defines actions like `Activate` (state change or interaction preparation), `Accept` (action confirmation), `HotKey` (hotkey activation), and others (e.g., `StartOfPage` for navigation). - **Command Handlers**: Views register handlers using `View.AddCommand`, specifying a `CommandImplementation` delegate that returns `bool?` (`null`: no command executed; `false`: executed but not handled; `true`: handled or canceled). - **Command Routing**: Commands are invoked via `View.InvokeCommand`, executing the handler or raising `CommandNotBound` if no handler exists. - **Cancellable Work Pattern**: Command execution uses events (e.g., `Activating`, `Accepting`) and virtual methods (e.g., `OnActivating`, `OnAccepting`) for modification or cancellation, with `Cancel` indicating processing should stop. ### Role in Terminal.Gui + The `Command` system bridges user input and view behavior, enabling: -- **Consistency**: Standard commands ensure predictable interactions (e.g., `Enter` triggers `Accept` in buttons, menus, checkboxes). +- **Consistency**: Standard commands ensure predictable interactions (e.g., `Enter` triggers `Accept` in buttons and menus). - **Extensibility**: Custom handlers and events allow behavior customization. - **Decoupling**: Events reduce reliance on sub-classing, though current propagation mechanisms may require subview-superview coordination. -### Note on `Cancel` Property -The `CommandEventArgs` class uses a `Cancel` property to indicate that a command event (e.g., `Accepting`) should stop processing. This is misleading, as it implies action negation rather than completion. A filed issue proposes replacing `Cancel` with `Handled` to align with input events (e.g., `Key.Handled`). This document uses `Cancel` to reflect the current implementation, with the appendix summarizing the proposed change. +## Default Command Implementations -## Implementation in View.Command +How a View responds to a Command is up to that View.

The efault implementation raises @Terminal.Gui.ViewBase.Accepting. If an override does not handle the command, the peer-Views are checked to see if any is a `Button` with `IsDefault` set. If so, `Accept` is invoked on that view. This enables "Default Button" support in forms. If there is no default button, or the default button does not handle the event, `Accept` is propagated up the SuperView hierarchy until handled. +- @Terminal.Gui.Input.Command.Activate - Provides built-in support for a common user action in Views: making the view, or something within the view active. The default implementation raises @Terminal.Gui.ViewBase.Activating and, if it wasn't handled and the view can be focused, sets focus to the View. +- @Terminal.Gui.Input.Command.HotKey - Provides support for accepting or activating a View with the keyboard. The default implementation raises @Terminal.Gui.ViewBase.HotKey and, if it wasn't handled, sets focus to the View. + +Each of these default implementations uses CWP-style events to enable subclasses or external code to override or change the default behavior.
