Accessibility Features

This feature enhances usability for all users by providing built-in support for screen readers, focus cues, and keyboard navigation.

Overview

The Accessibility Features enable developers to create inclusive applications by configuring properties that improve the control’s interaction with assistive technologies. These settings ensure that the button is easily discoverable, understandable, and operable by users with visual or motor impairments.

Detailed Documentation

Properties & Settings

The table below outlines the customizable accessibility-related properties and their roles:

Property	Description	Default Value	Type	Example Usage
ShowFocusCue	Determines whether a visual focus rectangle is displayed when the control receives keyboard focus.	false	bool	copyButton.ShowFocusCue = true;
AccessibilityName	Specifies the name announced by screen readers, allowing users to quickly identify the control’s purpose.	"Copy Button"	string	copyButton.AccessibilityName = "Copy text button";
AccessibilityDescription	Provides a detailed description of the control’s function for screen reader users, enhancing context and understanding.	"Button that copies text to clipboard"	string	copyButton.AccessibilityDescription = "Copies the text from the target control to the clipboard.";
AccessibilityHint	Offers additional instructions for using the control via keyboard navigation, helping users know how to interact with it.	"Press Space or Enter to copy text"	string	copyButton.AccessibilityHint = "Press Space or Enter to copy text.";

Additionally, the control includes a custom AccessibleObject that integrates these properties into the Windows accessibility framework, ensuring that screen readers and other assistive technologies can properly interpret and interact with the button.

Code Examples and Integration Demos

Basic Accessibility Integration Example

The example below demonstrates how to configure the accessibility properties for the SiticoneCopyButton in a simple WinForms application:

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

namespace AccessibilityDemo
{
    public class MainForm : Form
    {
        private SiticoneCopyButton copyButton;
        private TextBox sourceTextBox;

        public MainForm()
        {
            InitializeComponents();
        }

        private void InitializeComponents()
        {
            // Create and configure the source TextBox
            sourceTextBox = new TextBox
            {
                Location = new Point(20, 20),
                Width = 250,
                Text = "Accessible text to copy."
            };

            // Create and configure the SiticoneCopyButton with accessibility properties
            copyButton = new SiticoneCopyButton
            {
                Location = new Point(20, 60),
                Size = new Size(200, 40),
                Text = "Copy",
                TargetControl = sourceTextBox,
                ShowFocusCue = true,
                AccessibilityName = "Copy Text Button",
                AccessibilityDescription = "Button that copies the text from the text box to the clipboard",
                AccessibilityHint = "Press Space or Enter to copy text"
            };

            // Add controls to the form
            Controls.Add(sourceTextBox);
            Controls.Add(copyButton);
        }

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

Advanced Accessibility Integration Example

In this advanced example, the accessibility properties are customized to align with a comprehensive assistive technology strategy:

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

namespace AdvancedAccessibilityDemo
{
    public class CustomForm : Form
    {
        private SiticoneCopyButton copyButton;
        private TextBox demoTextBox;

        public CustomForm()
        {
            InitializeComponents();
        }

        private void InitializeComponents()
        {
            demoTextBox = new TextBox
            {
                Location = new Point(30, 30),
                Width = 300,
                Text = "Advanced accessible copy operation demo."
            };

            // Configure the copy button with advanced accessibility settings
            copyButton = new SiticoneCopyButton
            {
                Location = new Point(30, 80),
                Size = new Size(250, 50),
                Text = "Advanced Copy",
                TargetControl = demoTextBox,
                ShowFocusCue = true,
                AccessibilityName = "Advanced Copy Button",
                AccessibilityDescription = "This button copies the provided text into the clipboard and confirms the action.",
                AccessibilityHint = "Use Space or Enter to initiate the copy action"
            };

            Controls.Add(demoTextBox);
            Controls.Add(copyButton);
        }

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

Additional Useful Sections

Integration Checklist

Item	Check
Enable Focus Cues	Set ShowFocusCue to true to ensure a visual focus indicator is displayed when the control receives keyboard focus.
Provide Descriptive Text	Verify that AccessibilityName, AccessibilityDescription, and AccessibilityHint are clear and descriptive.
Test Keyboard Navigation	Confirm that the control is fully operable via keyboard (e.g., Space and Enter keys trigger the copy operation).
Validate with Assistive Tools	Test the control using screen readers and other assistive technologies to ensure proper announcement and navigation.

Troubleshooting

Problem	Potential Cause	Suggested Fix
Control Not Announced Properly	Accessibility properties may be missing or not set correctly.	Verify that AccessibilityName, AccessibilityDescription, and AccessibilityHint are properly assigned.
No Visual Focus Indicator	ShowFocusCue may be disabled or overridden by another style.	Ensure ShowFocusCue is set to true and not modified by other UI settings.
Inaccurate Interaction Hints	The AccessibilityHint may be too generic or unclear for the intended audience.	Revise the AccessibilityHint to provide specific instructions (e.g., "Press Space or Enter to copy text").
