Events for Animation

This feature provides events that notify developers when specific animations—such as particle or hover effects—complete, enabling the execution of additional logic after an animation finishes.

Overview

The Events for Animation Feedback feature exposes two events within the navigation button control: ParticleAnimationCompleted and HoverAnimationCompleted. These events are raised when their respective animations conclude, allowing developers to hook custom behavior (e.g., logging, state updates, or triggering subsequent animations) immediately after the visual effects are finished. This integration point ensures that the application can respond dynamically to user interactions and animation lifecycles.

Event Summary

Event Name	Delegate Type	Triggered When	Description
ParticleAnimationCompleted	EventHandler	The particle effect animation completes	Notifies subscribers that the particle burst effect has finished after a button click.
HoverAnimationCompleted	EventHandler	The hover animation reaches its final state	Notifies subscribers that the hover animation transition has completed when the mouse enters the control.

---

Key Points

Key Point	Explanation
Asynchronous Animation Completion	The events allow the application to react as soon as animations finish, ensuring a responsive UI flow.
Simplified Post-Animation Logic	Developers can attach event handlers to implement additional behaviors or UI updates after animations conclude.
Decoupled Design	By exposing animation feedback events, the control promotes a modular approach, separating visual effects from business logic.

---

Best Practices

Best Practice	Explanation
Subscribe early in control initialization	Attach event handlers as part of the control setup to ensure that no animation completions are missed during runtime.
Keep event handlers lightweight	Ensure that the code within event handlers executes quickly to avoid delaying subsequent animations or affecting UI responsiveness.
Use events to chain animations or state updates	Leverage these events to trigger further UI updates or transitions, creating a fluid and dynamic user experience.

---

Common Pitfalls

Pitfall	Explanation
Not detaching event handlers	Failing to remove event handlers when the control is disposed or no longer needed can lead to memory leaks.
Heavy processing in event handlers	Placing long-running or blocking code in the event handler may cause UI freezes, impacting the overall user experience.
Overcomplicating the event logic	Avoid overly complex event logic that ties the animation feedback too tightly with business logic, which can reduce maintainability.

---

Usage Scenarios

Scenario	How to Implement	Code Example
Logging animation completions	Attach handlers to both events to log messages or update a status label whenever an animation completes.	csharp<br>// Log animation completions<br>navForwardButton.ParticleAnimationCompleted += (sender, e) => { Console.WriteLine("Particle animation finished."); };<br>navForwardButton.HoverAnimationCompleted += (sender, e) => { Console.WriteLine("Hover animation finished."); };<br>
Triggering subsequent UI transitions	Use the events to start another animation or update the UI state, such as enabling/disabling controls or changing content.	csharp<br>// Enable a control after animation completes<br>navForwardButton.ParticleAnimationCompleted += OnParticleComplete;<br><br>private void OnParticleComplete(object sender, EventArgs e)<br>{<br> myNextControl.Enabled = true;<br>}<br>
Coordinating multiple animation effects	Utilize the feedback events to synchronize different parts of the UI, ensuring that one effect only starts after another has fully completed.	csharp<br>// Chain animations<br>navForwardButton.HoverAnimationCompleted += (sender, e) => { StartSecondaryAnimation(); };<br>

Integration Example

Below is an extensive code example demonstrating how to subscribe to and utilize the animation feedback events in a .NET WinForms application:

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

namespace WinFormsAnimationEventsDemo
{
    public partial class MainForm : Form
    {
        // Declare the custom navigation forward button.
        private SiticoneNavForwardButton navForwardButton;
        private Label statusLabel;

        public MainForm()
        {
            InitializeComponent();
            InitializeControls();
        }

        private void InitializeControls()
        {
            // Instantiate and configure the navigation forward button.
            navForwardButton = new SiticoneNavForwardButton
            {
                Location = new Point(50, 50),
                Size = new Size(40, 40),
                // Additional property configurations for animation features can be done here.
                EnableParticles = true,
                EnableRippleEffect = true,
                EnablePulseEffect = true
            };

            // Instantiate a status label to display feedback.
            statusLabel = new Label
            {
                Location = new Point(50, 110),
                Size = new Size(300, 30),
                Text = "Animation status will be displayed here."
            };

            // Subscribe to animation feedback events.
            navForwardButton.ParticleAnimationCompleted += OnParticleAnimationCompleted;
            navForwardButton.HoverAnimationCompleted += OnHoverAnimationCompleted;

            // Add the controls to the form.
            Controls.Add(navForwardButton);
            Controls.Add(statusLabel);
        }

        // Event handler for particle animation completion.
        private void OnParticleAnimationCompleted(object sender, EventArgs e)
        {
            // Update the status label when the particle animation completes.
            statusLabel.Text = "Particle animation completed at " + DateTime.Now.ToLongTimeString();
        }

        // Event handler for hover animation completion.
        private void OnHoverAnimationCompleted(object sender, EventArgs e)
        {
            // Update the status label when the hover animation completes.
            statusLabel.Text = "Hover animation completed at " + DateTime.Now.ToLongTimeString();
        }

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

In the example above, the navigation button is initialized with its animation features enabled. Event handlers for both ParticleAnimationCompleted and HoverAnimationCompleted are attached. These handlers update a status label on the form to indicate when each animation completes, demonstrating how the events can be used to trigger additional logic in response to animation feedback.
