Initialize decimal input after an operation.
When freshInput is true, this handler appends "." to the previous operand. The next digit then replaces the display. For example, 2 + . 5 produces 5, not 2.5.
Set displayText to "0." and set freshInput to false when decimal input starts a new operand.

For Quickshell v0.3, confirm the stacking behavior of WlrLayer.BottomversusWlrLayer.Topfor aPanelWindow.
💡 Result:
In Quickshell v0.3, the stacking behavior for a PanelWindow using the Wayland layer shell is determined by the WlrLayer enum [1]. These layers define the Z-order of the window relative to other surfaces [2]: WlrLayer.Bottom: Positions the window above the background layer but usually below normal windows [1]. It is commonly used for desktop icons and widgets [2]. WlrLayer.Top: Positions the window above normal windows [1]. This is the default layer for PanelWindow in Quickshell [3], [4]. When using the WlrLayershell attached object, the layer property controls this positioning [3], [4]. Setting a PanelWindow to WlrLayer.Top (default) renders it above standard windows, while setting it to WlrLayer.Bottom places it behind them [2], [5]. Stacking within these layers is generally determined by the order in which surfaces are committed to the compositor [2].

Use WlrLayer.Top for the exclusive-zone panel.
exclusiveZone reserves layout space but does not change stacking. WlrLayer.Bottom allows normal windows to cover the panel. Remove the assignment or set it to WlrLayer.Top.

Quickshell v0.3.0 BackgroundEffect blurRegion Region radius passes official documentation
💡 Result:
In Quickshell v0.3.0, the BackgroundEffect component provides functionality to apply background blur behind a window [1][2]. The blur parameters are configured as follows: - blurRegion: This property takes a Region object (e.g., Region { item: root.contentItem }) that defines the specific area behind the surface to be blurred [1][2]. - radius and passes: These properties are used to control the appearance of the blur. The radius property defines the blur kernel size in pixels, and the passes property controls the number of blur iterations (where more passes typically result in a smoother but more computationally expensive effect) [3]. It is important to note that BackgroundEffect relies on the compositor supporting the ext-background-effect-v1 Wayland protocol [1][2]. If the compositor does not support this protocol, the blur effect will not be applied, although the window may still remain transparent [3]. Quickshell abstracts the underlying compositor-specific implementations [3].

Use BackgroundEffect for compositor-side background blur.
GaussianBlur blurs the background subtree, including its Text. It does not blur pixels behind the transparent PanelWindow.
Import Quickshell.Wayland. Set BackgroundEffect.blurRegion: Region { item: background }. Remove the layer effect. The compositor must support ext-background-effect-v1.

In Quickshell v0.2.0, the Hyprland module provides interface access to Hyprland's state via the Quickshell.Hyprland singleton [1][2]. Below is the documentation regarding the requested properties and methods: monitorFor(screen) This function takes a Quickshell screen object and returns the corresponding HyprlandMonitor object [1][2]. It is designed to map a Wayland monitor (as known to Quickshell) to a Hyprland-specific monitor instance [3][4]. activeWorkspace and focusedWorkspace - focusedWorkspace: This is a property of the Quickshell.Hyprland singleton [1][2]. It is a read-only property that returns the HyprlandWorkspace object currently focused by Hyprland (it may be null) [1][2]. - activeWorkspace: This property is generally associated with monitor-specific objects (like in the I3 module) [5][6] rather than the global Hyprland singleton. In the context of Hyprland, the global state is typically accessed through focusedWorkspace [1][2]. dispatch(request) This function is a member of the Quickshell.Hyprland singleton [1][2]. It allows you to execute a Hyprland dispatcher (e.g., dispatch("workspace 1")) to interact with the compositor [1][7]. on_current_monitor There is no specific "on_current_monitor" function or property in the Quickshell.Hyprland module. To work with the currently focused monitor, you should use the focusedMonitor property [8][1], which returns the HyprlandMonitor object that is currently in focus. General Notes - All Quickshell.Hyprland features require importing the module via import Quickshell.Hyprland [1][2]. - Quickshell v0.2.x is in active development, and API details (especially for IPC-related modules) may vary slightly between minor versions [9]. Always check the documentation specific to your installed version [10][11].

💡 Result:
The terms activeWorkspace and monitorFor are specific components of the Quickshell Hyprland module, which provides a declarative API for interacting with Hyprland [1]. They are not standard configuration options within the core Hyprland compositor itself. 1. activeWorkspace: This is a property of the HyprlandMonitor object in Quickshell [2]. It returns the HyprlandWorkspace currently active on that specific monitor [2]. 2. monitorFor: This is a function available on the main Hyprland object within Quickshell [1]. It accepts a screen argument and returns the HyprlandMonitor object that corresponds to that specific Quickshell screen [1]. These tools are intended for use when building custom shells or widgets for Hyprland using the Quickshell framework [1]. If you are looking for information on standard Hyprland configuration or IPC, you should refer to the official Hyprland Wiki, as these specific identifiers do not exist in the base compositor.

Hyprland dispatcher focus workspace on_current_monitor syntax
💡 Result:
In modern Hyprland configurations using the Lua-based dispatcher system (introduced for improved configurability), the legacy focusworkspaceoncurrentmonitor command is replaced by the focus dispatcher [1][2]. To focus a workspace on the current monitor using the Lua configuration syntax, you use the following function: hl.dsp.focus({ workspace = , on_current_monitor = true }) Parameters: - workspace: The target workspace (numeric ID, name, or relative identifier) [1][2]. - on_current_monitor: A boolean value set to true to enforce focusing the workspace specifically on the current monitor [1][3]. For example, to bind this action to a key in your Lua configuration: hl.bind("SUPER + 1", hl.dsp.focus({ workspace = "1", on_current_monitor = true })) If you are using tools or scripts that interface with Hyprland via IPC (such as older versions of Waybar), you may need to update the command string to this new format [3]: dispatch hl.dsp.focus({ workspace = , on_current_monitor = true }) Note that this functionality corresponds to the previous legacy dispatcher behavior, which was designed to provide XMonad/Qtile-style workspace switching [4].

Hyprland 0.55 hl.dsp.focus dispatcher syntax introduced version legacy dispatcher syntax
💡 Result:
In Hyprland 0.55, the configuration system underwent a major transition from the legacy "hyprlang" syntax to a new Lua-based API [1][2]. As part of this change, dispatchers were completely redesigned, moving from simple string-based commands to structured Lua functions under the hl.dsp namespace [3][4]. Key details regarding the dispatcher syntax: New Lua Dispatcher Syntax In the new Lua configuration, dispatchers are invoked as functions. For example, the focus dispatcher is accessed via hl.dsp.focus({ ... }) [3][5]. These functions accept tables of parameters rather than the positional string arguments used previously [3][6]. For instance, hl.dsp.focus({ direction = "left" }) is the new equivalent for moving focus, replacing the old string-based format [5]. Legacy Dispatcher Syntax and hyprctl The transition introduced breaking changes for external tools and scripts that rely on hyprctl dispatch [7]. 1. The legacy string-based syntax (e.g., hyprctl dispatch exec kitty) is no longer directly supported in the same way under the new architecture [7]. 2. When interacting with Hyprland via hyprctl dispatch, you must now use the Lua dispatcher format, wrapped in strings. The expected syntax is hyprctl dispatch 'hl.dsp.exec_cmd("kitty")' [7][8]. 3. While the legacy hyprland.conf (hyprlang) remains supported for a limited number of releases, the hyprctl dispatch utility has been updated to require the new structured syntax, which has caused issues for scripts and external shells that were not updated to the new format [7][1][8]. The hl.dsp namespace effectively encapsulates all available dispatchers, with categories such as hl.dsp.window for window-specific actions (e.g., hl.dsp.window.close()) [3][6]. There is no direct 1:1 mapping between old and new dispatchers because the system was rebuilt from the ground up [4]. Users are encouraged to refer to the updated documentation on the Hyprland wiki for the specific structure of each new dispatcher function [3][1].

site:github.com/hyprwm/Hyprland "hl.dsp.focus" "workspace"
💡 Result:
In the context of the Hyprland window manager and its Lua configuration API, hl.dsp.focus is a function used to generate a dispatcher object that changes the focus [1][2]. When used in the context of workspaces, hl.dsp.focus({ workspace =... }) is the standard method for switching or focusing a specific workspace [1][3]. It is typically bound to keys using the hl.bind function [1][2]. Key characteristics include: - Functionality: It acts as a dispatcher for focusing windows, monitors, or workspaces [1][3]. For example, hl.dsp.focus({ workspace = 1 }) switches the focus to workspace 1 [1]. - Relative Movement: You can also use it to cycle through workspaces (e.g., { workspace = "e+1" } for the next workspace or { workspace = "e-1" } for the previous one) [1][2]. - Implementation Detail: hl.dsp. functions in the Lua API return a dispatcher object rather than executing the action immediately [4][5]. To perform the action, the dispatcher must be passed to hl.bind (which handles the execution) or invoked via hl.dispatch when used within a custom Lua function or callback [4][5]. Example usage: hl.bind("SUPER + 1", hl.dsp.focus({ workspace = 1 })) hl.bind("SUPER + mouse_down", hl.dsp.focus({ workspace = "e+1" })) [1][2]

💡 Result:
There is no feature, configuration file, or dispatcher known as hl.dsp in Hyprland [1][2]. The term does not appear in official Hyprland documentation [1][2]. It is possible that hl.dsp is a misunderstanding or a typo for one of the following: 1. Dispatchers: Hyprland uses dispatchers (e.g., exec, killactive) within the main configuration file (hyprland.conf) to perform actions [1][3]. 2. Configuration files: Hyprland components use specific naming conventions, such as hyprland.conf for the main configuration, hypridle.conf for idle management [4], or xdph.conf for the desktop portal [5]. 3. File extensions: There is no.dsp file type used for Hyprland configuration [1][2]. If you are attempting to configure a specific Hyprland component, ensure you are referencing the correct configuration file name (typically ending in.conf) as documented in the official Hyprland wiki [1][2].

Hyprland 0.55 release Lua configuration API hyprctl dispatch compatibility
💡 Result:
Hyprland 0.55 marks a major transition where Lua has become the primary configuration language, replacing the legacy hyprlang format [1][2][3]. While existing hyprland.conf files remain temporarily supported for a short deprecation window (1-2 releases), the project strongly encourages migration to the new hyprland.lua format [1][4]. Regarding hyprctl dispatch compatibility, the release introduced a breaking change in how dispatchers are handled via the command line [5]. The legacy syntax (e.g., hyprctl dispatch exec ghostty) is no longer accepted [5]. Instead, users must use the new Lua-based dispatcher syntax, which involves calling the internal Lua dispatcher functions directly [5][6][7]. Key points for hyprctl dispatch in Hyprland 0.55 and later: 1. Mandatory Lua Syntax: All hyprctl dispatch commands must now follow the Lua function call format [5][7]. 2. New Format Example: Instead of the old command format, use hyprctl dispatch 'hl.dsp.exec_cmd("command_name")' [5][6]. 3. Impact: This change affects external scripts, launchers, and shell commands that previously relied on the legacy string-based dispatcher syntax [5]. 4. Dispatcher Organization: Dispatchers are now categorized under the hl.dsp table in Lua (e.g., hl.dsp.window, hl.dsp.workspace) [8][9]. For complex logic or dynamic interactions, the hyprctl eval command can also be used to execute arbitrary Lua strings directly within the compositor's Lua state [6]. Migration to the new API is necessary for continued compatibility with current and future Hyprland versions [3][4].

A single click triggers poweroff after 2 seconds without a hold.
shutdownTimer starts on click and increments shutdownHoldProgress every 50 ms. After 40 ticks the timer calls root.execute("systemctl poweroff"). The user does not need to keep the button pressed. The property name shutdownHoldProgress and the comment at Line 175 both describe a press-and-hold interaction, so the behavior does not match the intent. An accidental click powers off the machine unless the user clicks the tile again within 2 seconds.
Drive the timer from the press state of the MouseArea, or require an explicit second click without an auto-complete timer.

Quickshell v0.3 Quickshell.Io Process exec command arguments documentation wl-copy positional text argument
💡 Result:
In Quickshell (including version 0.3), the Quickshell.Io.Process type is used to execute external commands [1][2][3]. It does not run commands through a system shell by default; instead, it expects commands to be provided as a list of strings where each argument is a separate element [4][2][5]. For the wl-copy utility, which is a Wayland clipboard tool, you should pass the command and its arguments as a list to the command property or the exec method [2][6]. To use wl-copy with a positional text argument, you should construct the list as follows: Process { command: ["wl-copy", "your text here"] running: true } Alternatively, using the exec method: Process.exec({ command: ["wl-copy", "your text here"] }); Important implementation details: 1. No Shell Expansion: Because Quickshell does not use a shell for the command array, shell features like globbing, environment variable expansion, or piping (|) will not work directly [4][2]. 2. Piping with Shell: If you need to pipe data (e.g., passing output to wl-copy), you must explicitly invoke a shell, such as sh or bash [4][2]. Example using a shell to pipe: Process { command: ["sh", "-c", "printf '%s' 'your text here' | wl-copy"] running: true } 3. Quoting and Arguments: Since you provide the arguments as a list, you do not need to manually quote the text argument; the list structure handles this automatically, protecting against common shell injection vulnerabilities that occur when manually constructing command strings [2][7]. 4. Clipboard Service: For native clipboard management, consider using the built-in Clipboard singleton from Quickshell.Services if available in your version, as it provides reactive bindings to clipboard content without needing to manually spawn subprocesses [6].

wl-copy command line arguments positional argument stdin man page
💡 Result:
The wl-copy command, part of the wl-clipboard suite, copies text or data to the Wayland clipboard [1][2]. Positional Arguments The command accepts optional positional arguments, which are treated as the text to be copied [1][3]. If no positional arguments are provided, wl-copy automatically reads data from its standard input (stdin) [1][2]. Summary of Command Line Options wl-copy supports the following primary command line arguments: -p, --primary: Use the primary clipboard instead of the default clipboard [1][4]. -t mime/type, --type mime/type: Specify the MIME type for the data being copied (e.g., image/png) [1][5]. If not specified, the tool attempts to infer the MIME type automatically [3]. -n, --trim-newline: For wl-copy, this removes the trailing newline character if it is present in the input [1][5]. -c, --clear: Clears the clipboard instead of copying new data [4][5]. -f, --foreground: Runs the process in the foreground instead of forking into the background [5][6]. -s seat-name, --seat seat-name: Specifies the Wayland seat to use [1][5]. --sensitive: A hint that the content is sensitive (e.g., passwords), which may prevent clipboard managers from persisting the data [4][7]. -v, --version: Displays version information [1][4]. -h, --help: Displays a help message [1][4]. For further details, you can consult the manual page on your system by running man wl-copy [1][3].

Quickshell v0.3 Process.exec QML module import Quickshell.Io Process
💡 Result:
In Quickshell, the Process.exec function is a method available on the Process type provided by the Quickshell.Io module [1][2][3]. It is designed to launch a process with specified arguments while stopping any currently running process managed by that object [2][3]. Key details regarding Process.exec: 1. Usage: The function accepts a context parameter, which can be either a list of command arguments (e.g., ["date"]) or a JavaScript object containing configuration fields such as command, environment, clearEnvironment, and workingDirectory [2][3]. 2. Functionality: Calling exec is equivalent to setting the Process properties (running = false, updating parameters like command/environment, and then setting running = true) [2][3]. 3. Import Requirements: To use the Process type, you must import the required module in your QML file [1][4]: import Quickshell.Io Example implementation: Process { id: myProcess } // Later, perhaps in a signal handler or function: myProcess.exec(["date"]) // Or using a context object: myProcess.exec({ command: ["ls", "-l"], workingDirectory: "/home/user" }) Note that this function does not execute commands through a shell by default; it expects arguments as separate elements in a list [2][3]. To run shell commands or pipelines, you must explicitly invoke the shell, for example by using ["sh", "-c", "your command here"] [2][3].

Quickshell v0.3.0 PopupAnchor anchor.item margins gravity Edges.Top documentation
💡 Result:
In Quickshell v0.3.0, PopupAnchor is used to position popup windows relative to an item or window [1]. The properties margins, gravity, and edges work together to determine how a popup attaches to its anchor rectangle [1][2][3]. Margins: The margins property defines a margin applied to the anchor rectangle [2][3]. It accepts an array format [left, top, right, bottom] and is most useful when anchoring to an item where the default anchor rectangle matches the item's dimensions [2][3][4]. Edges: The edges property specifies the point on the anchor rectangle where the popup should attach [2][3]. It defaults to Edges.Top | Edges.Left [2][3]. Opposing edges (e.g., Edges.Left | Edges.Right) are not allowed [2][3]. Gravity: The gravity property determines the direction in which the popup should expand relative to the anchor point [2][3]. It defaults to Edges.Bottom | Edges.Right [2][3]. Like edges, opposing gravity settings are not permitted [2][3]. When using an item as an anchor, the default anchor rectangle matches the dimensions of that item [1][5]. While the system calculates the initial position when the popup is shown, you can call updateAnchor if the item's position changes to recalculate the anchor rectangle [1][6]. If more complex positioning is required, you can set the window property to the item's parent window and handle the anchoring signal [1][5].

💡 Result:
In user interface design and layout frameworks, margins and gravity are distinct concepts used to control the spacing and positioning of elements [1]. Margins are used to define the empty space outside of an item's boundaries, creating a buffer between the element and its neighbors or the edges of its container [1]. Gravity determines the alignment or placement of an element within a larger available space, such as pinning an item to the top-left or centering it within a parent container [1]. In systems where these properties interact—such as the Quickshell framework—margins are often applied to anchor rectangles to adjust the effective area of an item, while gravity defines the directional placement or expansion behavior relative to those anchors [1]. Other frameworks, such as Android, distinguish between gravity (which aligns content inside a view) and layout_gravity (which aligns the view itself within its parent), while margins are used to offset the view from its surroundings. These properties are typically used together to create precise, responsive layouts where an item is first positioned via gravity and then spaced via margins [1].

Anchor the preview to iconBg.
delegateItem.x is relative to RowLayout, and dock.y is not relative to dock. The popup can therefore appear away from its icon. Use the item anchor with top-edge gravity.
Proposed fix
anchor {
- window: dock
- rect.x: delegateItem.x + (delegateItem.width / 2) - 100
- rect.y: dock.y - 130
+ item: iconBg
+ edges: Edges.Top
+ gravity: Edges.Top
+ margins.top: 10

Quickshell v0.3.0 PopupWindow valid anchor visible no anchor PopupAnchor documentation
💡 Result:
In Quickshell v0.3.0, the PopupWindow component requires a valid anchor to be displayed [1][2]. Even if the visible property is set to true, the popup will not be shown until it possesses a valid anchor relative to a window [1][3]. The anchor property is a read-only PopupAnchor object [1][2]. It defines the positioner relative to another item or window [4][2]. You can configure the anchor by setting properties on the anchor object, such as the parent window, as shown in the following example: PopupWindow { anchor.window: parentWindow // or anchor { window: parentWindow } } The PopupAnchor documentation specifies that the popup's position relative to its parent window is calculated only when it is initially shown [4]. If you are anchoring to an item, the anchor does not automatically track the item's position changes; in such cases, the updateAnchor function can be called to manually recalculate the anchor rectangle [4][5].

Qt QML property binding name resolution nested object property shadows outer property self-referential binding
💡 Result:
In QML, name resolution and property binding behavior are governed by a well-defined JavaScript-based scope hierarchy [1][2]. Name Resolution and Shadowing QML resolves names based on the scope object, which typically includes the object's own properties, properties of its parent, and any IDs defined in the current scope [1][2]. 1. IDs: Explicitly defined IDs always take precedence over other property names, except for those within the immediate JavaScript scope [1][2]. 2. Shadowing: If a property name is defined in both a child and an outer/parent scope, the child's property shadows the outer one within the child's scope [1][2]. Because QML does not use a mechanism like the C++ scope resolution operator (e.g.,::) to access shadowed properties, accessing the outer property directly when it is shadowed by an inner property is generally not possible [3]. 3. Disambiguation: To avoid or resolve shadowing ambiguities, it is best practice to use unique property names [4]. Alternatively, you can explicitly reference the desired property through an object's ID (e.g., parentObject.propertyName) or, in certain JavaScript contexts, use the this keyword to refer to the object that receives the binding [5][3]. Self-Referential Binding A self-referential binding occurs when a property is bound to its own value (e.g., width: width * 2) or creates a circular dependency chain [6][7]. 1. Binding Loops: When a property A depends on property B, and property B depends on property A, the QML engine detects this as a binding loop and will typically issue a warning to prevent infinite recursion [6][7]. 2. Resolution: To avoid these loops, you must ensure dependencies are unidirectional [6]. Common techniques include: - Introducing a third, independent property as a source of truth [6]. - Using signal handlers (e.g., on[PropertyName]Changed) to imperatively update a property instead of using a declarative binding [6]. - Using the Binding type for complex, conditional, or remote dependencies, which can help manage the activation and restoration of values [7][8]. Note: Imperative assignments (using = in JavaScript) on a property that already has a declarative binding will break that binding [6][9]. If you must modify a property via JavaScript while maintaining binding behavior, use the Qt.binding function [5][6].

Qt QML Repeater JavaScript array model object property mutation modelData binding notification var object
💡 Result:
In QML, using a standard JavaScript array (assigned to a property of type var) as a model for a Repeater does not provide automatic change notification [1][2]. When you modify such an array using JavaScript methods like push, splice, or direct index assignment, the QML engine is not notified of the change, and the Repeater will not update its visual representation [3][1][4]. Key technical implications: 1. Manual Reassignment Required: To force a Repeater to refresh after modifying a JavaScript array model, you must explicitly reassign the array to the Repeater's model property (e.g., repeater.model = myJsArray) [3][4][2]. This triggers a full re-evaluation, causing the Repeater to destroy all existing delegate items and recreate them from scratch, which can lead to significant performance overhead in large lists [3][4][5]. 2. Lack of Signaling: Unlike model types like ListModel or QAbstractItemModel—which are designed to emit signals (e.g., rowsInserted, rowsRemoved) that the Repeater listens to for incremental updates—a standard JavaScript array is a simple value type [1][4]. The QML engine cannot track internal mutations to these arrays [1][4]. 3. Alternatives for Dynamic Updates: If your application requires frequent, dynamic updates to the model, it is recommended to use: - ListModel: A built-in, signal-aware model that supports methods like append, insert, and remove for incremental UI updates [1][4][5]. - QML List Type (Qt 6+): Using property list can sometimes provide better integration, though ListModel remains the standard for complex dynamic data [3][2]. 4. Data Binding and modelData: When using a JavaScript array, QML internally wraps the array to make items accessible via the modelData property [6][7]. However, because this is an internal transformation, complex JavaScript objects stored in the array may lose non-variant properties (like JavaScript functions) during the process, as the model is effectively converted to a format compatible with QVariants [7]. In summary, standard JavaScript arrays are suitable for static data, but their lack of change notification makes them inefficient for dynamic UI updates [3][1][8]. For dynamic scenarios, use ListModel or a C++ model to ensure the Repeater updates items incrementally instead of rebuilding the entire view [4][5].

site:doc.qt.io/qt-6 qml var property object changes binding notification JavaScript object
💡 Result:
In QML, assigning a JavaScript object to a property of type var does not automatically provide change notification for the individual properties of that object [1]. Consequently, if a binding depends on a property inside a JavaScript object assigned to a var property, the binding will not re-evaluate when that internal property changes [1]. The QML engine only emits a change notification for a var property when the property itself is reassigned to a new object or value [1]. To trigger a binding update, you must either: 1. Reassign the entire var property to a new object or value [1]. 2. Use a specialized object type or QML-aware data structure if you require fine-grained change tracking for internal properties [2]. If you need to detect changes in such objects, you must handle the notification manually. This typically involves using signals or calling a notify function when you modify the internal properties of your JavaScript object [3]. For more complex scenarios where automatic change tracking is required, consider using standard QML object types or exposing C++ objects with properly defined Q_PROPERTY attributes that include NOTIFY signals [4]. When a property on a standard QML object type changes, the engine automatically emits a change signal, allowing bindings that reference that property to update correctly [3][2].

site:doc.qt.io/qt-6 Repeater model JavaScript array modelData QML
💡 Result:
In QML, a JavaScript array can be used as a model for a Repeater component [1][2]. When a JavaScript array is assigned to the model property, the Repeater iterates over the array elements, creating a delegate instance for each entry [1][2]. Data Access in Delegates: Within the Repeater's delegate, the data from the array is exposed through the read-only modelData property [1][2]. Example Usage: Row { Repeater { model: ["apples", "oranges", "pears"] Text { required property string modelData text: "Data: " + modelData } } } Behavior Details: 1. Singular Data: If the array contains primitive types like strings or numbers, each element is made available directly via modelData [2]. 2. Structured Data: If the array contains JavaScript objects, each object is accessible via the modelData property, and the individual properties of that object may be accessed directly within the delegate's scope [2]. 3. Dynamic Updates: While you can use standard JavaScript arrays, note that changes to a JavaScript array (e.g., pushing or popping elements) are not automatically detected by the Repeater unless the model is reassigned or a more robust model type (like ListModel) is used for dynamic data binding [3]. For advanced data handling or complex C++ integration, types like QVariantList or QAbstractItemModel are recommended [4][5].

Use a notifying model for control toggles.
The delegate mutates modelData.active in a JavaScript-array model. This does not update bindings that read active. Use a ListModel with setProperty(), or reassign the model after each toggle.

JavaScript-array model used by the control toggle view with a notifying
ListModel, preserving the existing labels, icons, and active states. Update the
MouseArea handler in the delegate to call setProperty() on the containing model
using the delegate index when toggling active, so all bindings react to the
change.
