Focus and Accessibility Customization

This feature allows developers to customize the focus cues and accessibility settings of the rating control to improve usability and compliance with accessibility standards.

Overview

The Focus and Accessibility Customization feature provides properties and accessibility settings to ensure that the rating control can visually indicate focus and support assistive technologies. Developers can enable or disable focus cues and set the focus cue color, while the control also exposes accessibility properties (such as AccessibleName, AccessibleRole, and AccessibleDescription) that facilitate integration with accessibility tools.

Key Points

Aspect	Description
FocusCueEnabled	Enables or disables the drawing of a focus cue (a dotted rectangle) around the control when focused.
FocusCueColor	Sets the color of the focus cue, providing visual feedback when the control has keyboard focus.
Accessible Properties	Exposes properties like AccessibleName, AccessibleRole, and AccessibleDescription to support assistive technologies.
Accessibility Instance	Implements a custom AccessibleObject to further enhance screen reader support and user interaction.

---

Best Practices

Area	Guidance
Visual Feedback Consistency	Ensure that the FocusCueColor contrasts well with the control’s background for clear visibility.
Accessibility Compliance	Set meaningful values for AccessibleName, AccessibleRole, and AccessibleDescription to improve usability for assistive technology users.
Enable Focus Cues Strategically	Enable FocusCueEnabled when the control is expected to receive keyboard focus and interact with users.
Custom Accessible Objects	Extend or customize the AccessibleObject if additional accessibility features are required.

---

Common Pitfalls

Issue	Description
Poor Contrast for Focus Cue	Choosing a FocusCueColor that does not contrast sufficiently with the background can make focus cues hard to see.
Inadequate Accessibility Labels	Neglecting to set descriptive AccessibleName or AccessibleDescription values may hinder usability for assistive technology users.
Overuse of Focus Cues	Enabling focus cues in contexts where they are not needed can clutter the UI and confuse users.
Ignoring Custom Accessibility	Relying solely on default accessibility implementations without testing with screen readers may lead to suboptimal user experiences.

---

Usage Scenarios

Scenario	Explanation
Keyboard Navigation	Enable focus cues to assist users who navigate the application using the keyboard.
High-Contrast Environments	Set a distinctive FocusCueColor for users who require high-contrast visual elements for better readability.
Assistive Technology Integration	Use accessibility properties to ensure that screen readers and other assistive technologies correctly interpret the control.
Custom Theming	Customize focus cues to match the overall theme of your application while still providing clear visual indicators.

---

Real Life Usage Scenarios

Scenario	Description
Enterprise Applications	In applications where keyboard navigation is critical, focus cues can improve workflow and accessibility for power users.
Public-Facing Web Applications	Ensuring that focus cues and accessibility properties are well configured can help meet regulatory accessibility standards.
Educational Software	Clear focus indicators and accessible descriptions assist users with learning disabilities in interacting with the control.
Assistive Device Integration	Applications used in conjunction with assistive devices benefit from customized accessible properties and focus cues.

Code Examples

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

Example 1: Enabling Focus Cues and Setting Focus Cue Color

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 focus cues enabled
            var ratingControl = new SiticoneRating
            {
                FocusCueEnabled = true,              // Enable visual focus cues
                FocusCueColor = Color.Blue,            // Set the focus cue color to blue
                Location = new Point(10, 10)
            };

            Controls.Add(ratingControl);
        }

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

Example 2: Customizing Accessible Properties

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

namespace AccessibleRatingApp
{
    public class MainForm : Form
    {
        public MainForm()
        {
            // Create and configure the rating control with custom accessibility settings
            var ratingControl = new SiticoneRating
            {
                Location = new Point(10, 10)
            };

            // Set accessible properties to improve screen reader support
            ratingControl.AccessibleName = "Product Rating";
            ratingControl.AccessibleRole = AccessibleRole.Slider;
            ratingControl.AccessibleDescription = "Use the arrow keys to adjust the product rating.";

            Controls.Add(ratingControl);
        }

        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();

        }
    }
}

Example 3: Combining Focus and Accessibility Customization

using SiticoneNetFrameworkUI;

namespace CustomAccessibleRatingApp
{
    public class MainForm : Form
    {
        public MainForm()
        {
            // Create and configure the rating control with focus cues and accessibility properties
            var ratingControl = new SiticoneRating
            {
                FocusCueEnabled = true,
                FocusCueColor = Color.Green,
