Trigger Feedback

Manually invoke visual and auditory feedback when the Siticone CheckBox is in a read-only state, enhancing user interaction and accessibility.

Overview

The TriggerReadOnlyFeedback() method of the SiticoneCheckBox control provides developers with the ability to programmatically activate feedback mechanisms when the checkbox is set to read-only. This method is particularly useful in scenarios where user interactions need to be restricted, and immediate feedback is required to inform the user about the read-only state. By invoking this method, the control can visually indicate its non-interactive status through animations (e.g., shake effect) and auditory cues (e.g., beep sound), thereby enhancing the user experience and accessibility.

Method Signature

public void TriggerReadOnlyFeedback()

Detailed Description

The TriggerReadOnlyFeedback() method serves as an explicit mechanism to provide feedback when the SiticoneCheckBox is in a read-only state. When called, the method checks if the checkbox is indeed read-only (IsReadOnly property is true). If so, it proceeds to execute feedback actions based on the control's configuration:

1. Auditory Feedback (CanBeep): If the CanBeep property is set to true, the method plays a beep sound using the system's default beep sound. This auditory cue alerts users that their interaction is not permitted.

2. Visual Feedback (CanShake): If the CanShake property is true and the control is not already in the process of shaking (_isShaking is false), the method initiates a shake animation. This visual effect serves as a clear indication that the checkbox is currently non-interactive.

By providing both auditory and visual feedback, the method ensures that users receive immediate and noticeable cues about the read-only status of the checkbox, thereby preventing confusion and enhancing usability.

Usage

Developers can call the TriggerReadOnlyFeedback() method in response to specific events or conditions where the checkbox needs to inform the user about its read-only state. This can be particularly useful in form validations, conditional UI states, or when certain functionalities are temporarily disabled.

Example

Example 1: Triggering Read-Only Feedback Upon Invalid Input

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

public class ReadOnlyFeedbackForm : Form
{
    private SiticoneCheckBox readOnlyCheckBox;
    private Button validateButton;

    public ReadOnlyFeedbackForm()
    {
        InitializeComponent();
    }

    private void InitializeComponent()
    {
        this.readOnlyCheckBox = new SiticoneCheckBox();
        this.validateButton = new Button();
        this.SuspendLayout();

        // 
        // readOnlyCheckBox
        // 
        this.readOnlyCheckBox.Text = "Accept Terms and Conditions";
        this.readOnlyCheckBox.Location = new Point(50, 50);
        this.readOnlyCheckBox.Size = new Size(250, 35);
        this.readOnlyCheckBox.IsReadOnly = true;       // Set checkbox to read-only
        this.readOnlyCheckBox.CanBeep = true;          // Enable beep sound
        this.readOnlyCheckBox.CanShake = true;         // Enable shake animation

        // 
        // validateButton
        // 
        this.validateButton.Text = "Validate";
        this.validateButton.Location = new Point(50, 100);
        this.validateButton.Click += new EventHandler(this.ValidateButton_Click);

        // 
        // ReadOnlyFeedbackForm
        // 
        this.ClientSize = new Size(350, 200);
        this.Controls.Add(this.readOnlyCheckBox);
        this.Controls.Add(this.validateButton);
        this.Text = "SiticoneCheckBox - TriggerReadOnlyFeedback Example";
        this.ResumeLayout(false);
    }

    private void ValidateButton_Click(object sender, EventArgs e)
    {
        // Attempt to toggle the checkbox state
        if (readOnlyCheckBox.IsReadOnly)
        {
            // Trigger read-only feedback to inform the user
            readOnlyCheckBox.TriggerReadOnlyFeedback();
        }
        else
        {
            // Toggle the checkbox state if not read-only
            readOnlyCheckBox.Checked = !readOnlyCheckBox.Checked;
        }
    }
}

Explanation:

• The form contains a SiticoneCheckBox labeled "Accept Terms and Conditions", which is set to read-only (IsReadOnly = true).

• The CanBeep and CanShake properties are enabled to allow auditory and visual feedback when the checkbox is interacted with while in a read-only state.

• A Validate button is provided. When clicked, it attempts to toggle the checkbox's state.

  • If the checkbox is read-only, it invokes the TriggerReadOnlyFeedback() method to inform the user that the checkbox cannot be interacted with.

  • If the checkbox is not read-only, it toggles the Checked state as usual.

This example demonstrates how to use the TriggerReadOnlyFeedback() method to provide immediate feedback to users attempting to interact with a read-only checkbox.
