Appearance Customization

This feature allows developers to change the visual appearance of the rating control by modifying colors, shapes, and images.

Overview

The Appearance Customization feature provides several properties to adjust the visual elements of the rating control. Developers can set colors for filled, hovered, and empty stars, choose a specific star shape from predefined options, or supply a custom image to override the default drawing.

---

Key Points

Aspect	Description
StarColor	Specifies the color of the filled (active) stars.
HoverColor	Sets the color for stars when they are hovered over by the mouse.
EmptyColor	Defines the color of the empty (inactive) stars.
StarImage	Allows a custom image to be used for the stars; when set, it overrides the default drawing.
StarShape	Determines the shape of the rating symbols, with options including Star, Heart, ThumbUp, Circle, and Square.

---

Best Practices

Area	Guidance
Color Consistency	Choose colors that complement your application's overall theme and improve usability.
Custom Image Usage	Use a custom star image (via StarImage) only when necessary, as it overrides vector graphics.
Shape Selection	Select a StarShape that aligns with the desired look and feel of your application.
User Feedback	Consider using contrasting colors for hover states (via HoverColor) to provide clear visual cues.

---

Common Pitfalls

Issue	Description
Inconsistent Colors	Using colors that clash with the overall UI design may reduce readability and visual appeal.
Overriding Default Behavior	Setting a custom image via StarImage without testing can lead to unexpected visual results.
Unclear Hover Feedback	Neglecting the hover color may result in insufficient visual feedback during user interaction.
Misconfigured Shapes	Choosing an inappropriate shape for your application's context might confuse users.

---

Usage Scenarios

Scenario	Explanation
Themed Applications	Customize star colors to match application themes or branding guidelines.
Dynamic Visual Feedback	Change hover and empty colors to provide immediate visual cues for user interaction.
Custom UI Elements	Use a custom star image for a unique rating system that aligns with a specific design language.
Alternative Symbol Designs	Select from different star shapes (e.g., Heart, ThumbUp) to better represent the context of the rating (e.g., feedback for products versus service satisfaction).

---

Real Life Usage Scenarios

Scenario	Description
E-Commerce Platforms	Use distinctive colors to indicate product ratings and use hover effects to enhance interactivity.
Restaurant and Service Reviews	Apply themed colors and heart shapes to capture emotional responses in review applications.
Mobile and Web Hybrid Apps	Incorporate custom star images to align with mobile-first designs while maintaining consistency.
Interactive Dashboards	Use varying shapes and colors to create visually appealing and intuitive rating displays.

Code Examples

Below are several code examples demonstrating how to integrate and use the Appearance Customization features.

Example 1: Basic Appearance Setup

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

namespace SampleRatingApp
{
    public class MainForm : Form
    {
        public MainForm()
        {
            // Create and configure the rating control with custom colors and shape
            var ratingControl = new SiticoneRating
            {
                StarColor = Color.Gold,         // Filled stars color
                HoverColor = Color.Orange,        // Hover color for stars
                EmptyColor = Color.LightGray,     // Empty stars color
                StarShape = SiticoneRating.StarShapeType.Star, // Default star shape
                Location = new Point(10, 10)
            };

            Controls.Add(ratingControl);
        }

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

Example 2: Using a Custom Star Image

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

namespace SampleRatingApp
{
    public class MainForm : Form
    {
        public MainForm()
        {
            // Load a custom star image
            Image customStar = Image.FromFile("customStar.png");

            // Create and configure the rating control to use the custom image
            var ratingControl = new SiticoneRating
            {
                StarImage = customStar, // Override default star drawing with a custom image
                StarColor = Color.Transparent, // StarColor is ignored when StarImage is set
                HoverColor = Color.Transparent,
                EmptyColor = Color.Transparent,
                Location = new Point(10, 10)
            };

            Controls.Add(ratingControl);
        }

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

Example 3: Customizing Star Shape

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

namespace SampleRatingApp
{
    public class MainForm : Form
    {
        public MainForm()
        {
            // Create and configure the rating control with a heart shape
            var ratingControl = new SiticoneRating
            {
                StarShape = SiticoneRating.StarShapeType.Heart,
                StarColor = Color.Red,
                HoverColor = Color.Pink,
                EmptyColor = Color.LightGray,
                Location = new Point(10, 10)
            };

            Controls.Add(ratingControl);
        }

        static void Main()
        {
            Application.EnableVisualStyles();
