Events for Feedback

A feature that provides hooks for developers to respond to key interactions and state changes in the control, enabling customized behavior and feedback integration.

Overview

The Events for Customization and Feedback feature in the SiticoneNotificationButton control exposes several events that allow developers to extend and integrate the control’s behavior with application logic. These events include notifications when the mute state changes, when particle or hover animations complete, and when a long-press gesture is recognized. By subscribing to these events, developers can trigger custom actions, update UI elements, or log state changes to enhance user interaction and feedback.

Key Points

Aspect	Details
Mute State Changed	The MuteStateChanged event is triggered when the mute state of the bell icon toggles.
Particle Animation End	The ParticleAnimationCompleted event is fired when the particle effect animation has finished.
Hover Animation End	The HoverAnimationCompleted event is raised upon completion of the hover effect animation.
Long-Press Gesture	The LongPress event signals that a long-press gesture has been detected on the control.

---

Best Practices

Best Practice	Explanation
Subscribe only to necessary events	To avoid unnecessary overhead, subscribe only to the events required for your application's logic.
Implement robust event handlers	Ensure that event handlers include error handling and are optimized to run quickly, especially if they trigger UI updates.
Decouple UI updates from event logic	Use patterns such as the Observer or Command pattern to separate event-handling logic from UI updates for better maintainability.
Log event triggers for debugging	Optionally log event triggers (such as mute toggling or animation completions) during development to help diagnose issues.

---

Common Pitfalls

Pitfall	Explanation	Recommendation
Over-subscribing to events	Subscribing to too many events can lead to performance issues and complex code management.	Subscribe only to events that are essential for your application’s functionality.
Not unsubscribing from events	Failing to detach event handlers (especially in dynamic or long-lived controls) can cause memory leaks.	Always unsubscribe from events when the control is disposed or when the handlers are no longer needed.
Overloading event handlers with heavy processing	Intensive operations in event handlers can lead to UI lag or unresponsive behavior.	Offload heavy processing to background threads or use asynchronous patterns within event handlers.

---

Usage Scenarios

Scenario	When to Use
Customizing mute behavior	When an application needs to perform additional actions (such as updating a status label) whenever the mute state changes.
Triggering follow-up actions after animations	To initiate subsequent UI changes once a visual effect (particle or hover animation) completes.
Implementing advanced gesture handling	When a long-press gesture should trigger contextual menus or additional functionality in the application.
Integrating analytics or logging	When it is necessary to log user interactions and animation completions for analytics or debugging purposes.

Code Examples

Example 1: Handling MuteStateChanged Event

This example demonstrates how to subscribe to the MuteStateChanged event to update a status label when the bell icon’s mute state changes.

using System;
using System.Drawing;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;

public class MuteStateExampleForm : Form
{
    private SiticoneNotificationButton notificationButton;
    private Label statusLabel;

    public MuteStateExampleForm()
    {
        notificationButton = new SiticoneNotificationButton
        {
            Location = new Point(50, 50),
            Size = new Size(50, 50),
            CanMute = true,
            NotificationTooltip = "Click to toggle mute"
        };
        notificationButton.MuteStateChanged += NotificationButton_MuteStateChanged;

        statusLabel = new Label
        {
            Location = new Point(50, 120),
            AutoSize = true,
            Text = "Mute state: Unmuted"
        };

        Controls.Add(notificationButton);
        Controls.Add(statusLabel);
    }

    private void NotificationButton_MuteStateChanged(object sender, EventArgs e)
    {
        // Update the status label based on the current mute state
        statusLabel.Text = $"Mute state: {(notificationButton.IsMuted ? "Muted" : "Unmuted")}";
    }

    [STAThread]
    public static void Main()
    {
        Application.EnableVisualStyles();
        Application.Run(new MuteStateExampleForm());
    }
}

Example 2: Using ParticleAnimationCompleted Event

This example shows how to handle the ParticleAnimationCompleted event to perform an action (e.g., display a message) when the particle effect has finished.

using System;
using System.Drawing;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;

public class ParticleAnimationExampleForm : Form
{
    private SiticoneNotificationButton notificationButton;

    public ParticleAnimationExampleForm()
    {
        notificationButton = new SiticoneNotificationButton
        {
            Location = new Point(50, 50),
            Size = new Size(50, 50),
            EnableParticles = true,
            ParticleCount = 20,
            ParticleSpeed = 3f,
            NotificationTooltip = "Click to trigger particle animation"
        };

        notificationButton.ParticleAnimationCompleted += NotificationButton_ParticleAnimationCompleted;

        Controls.Add(notificationButton);
    }

    private void NotificationButton_ParticleAnimationCompleted(object sender, EventArgs e)
    {
        MessageBox.Show("Particle animation has completed.", "Animation Completed");
    }

    [STAThread]
    public static void Main()
    {
        Application.EnableVisualStyles();
        Application.Run(new ParticleAnimationExampleForm());
    }
}

Example 3: Responding to LongPress and HoverAnimationCompleted Events

This example demonstrates subscribing to both the LongPress and HoverAnimationCompleted events to trigger specific actions when these interactions occur.

using System;
using System.Drawing;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;

public class GestureEventsExampleForm : Form
{
    private SiticoneNotificationButton notificationButton;

    public GestureEventsExampleForm()
    {
        notificationButton = new SiticoneNotificationButton
        {
            Location = new Point(50, 50),
            Size = new Size(50, 50),
            LongPressDuration = 1000, // 1 second for long press
            NotificationTooltip = "Hold for options, hover for animation"
        };

        notificationButton.LongPress += NotificationButton_LongPress;
        notificationButton.HoverAnimationCompleted += NotificationButton_HoverAnimationCompleted;

        Controls.Add(notificationButton);
    }

    private void NotificationButton_LongPress(object sender, EventArgs e)
    {
        MessageBox.Show("Long press detected. Displaying additional options.", "Long Press");
    }

    private void NotificationButton_HoverAnimationCompleted(object sender, EventArgs e)
    {
        // This could trigger additional UI changes after hover animation finishes
        Console.WriteLine("Hover animation completed.");
    }

    [STAThread]
    public static void Main()
    {
        Application.EnableVisualStyles();
        Application.Run(new GestureEventsExampleForm());
    }
}
