Rounded Corners & Shape Customization

This feature allows developers to customize the curvature of each corner of the progress bar, enabling unique and visually appealing shapes.

Overview

The Rounded Corners & Shape Customization feature of the control provides fine-grained control over the appearance of each corner through individual radius properties. It also includes an option to automatically set all corners to a uniform, perfectly circular curvature using the MakeRadial property. This flexibility enables developers to match the control's appearance to their application’s design language.

Properties and Their Details

The following table summarizes the main properties associated with rounded corners and shape customization:

Property	Description	Default Value
CornerRadiusTopLeft	Sets the curvature radius of the top-left corner.	15
CornerRadiusTopRight	Sets the curvature radius of the top-right corner.	15
CornerRadiusBottomLeft	Sets the curvature radius of the bottom-left corner.	15
CornerRadiusBottomRight	Sets the curvature radius of the bottom-right corner.	15
MakeRadial	When true, calculates and applies maximum possible radius for a perfect circular shape based on the control size.	true

Key Points

Aspect	Details
Customizability	Each corner's curvature can be adjusted independently using the four CornerRadius properties.
Automatic Adjustment	Enabling MakeRadial ensures that the corners automatically adjust to form a circle, based on the control's dimensions.
Dynamic Redraw	Changes to these properties trigger an update of the control's region and force a repaint to reflect the new shape.

---

Best Practices

Practice	Explanation
Consistent Sizing	When using MakeRadial, ensure that the control's height and width are similar to achieve a uniform circular appearance.
Gradual Adjustments	Adjust the corner radii gradually when not using MakeRadial to maintain a balanced visual design and avoid disproportionate corners.
Test in Different Sizes	Verify the appearance at various sizes by dynamically resizing the control to ensure the rounded corners render correctly at all dimensions.

Common Pitfalls

Pitfall	Explanation	Avoidance Strategy
Overlapping Radii	Setting corner radii larger than half the width or height of the control may lead to visual glitches.	Always ensure that the radius value does not exceed half the minimum of the control's width or height (this is automatically clamped in the code).
Ignoring MakeRadial Effects	Manually setting corner radii when MakeRadial is enabled may produce unexpected results.	Use MakeRadial exclusively for a circular effect, or disable it if custom individual corner radii are desired.
Inconsistent Control Sizing	Changing the control size without updating the region can cause improper rendering of the rounded corners.	Use the control’s OnSizeChanged event (which calls UpdateControlRegion) to ensure that the rounded corners adjust to new dimensions automatically.

Usage Scenarios

Scenario	Description	Sample Code Integration
Custom UI Theme	When developing a themed application where controls need to have a specific rounded look.	csharp<br>// Initialize the progress bar with custom corner radii<br>SiticoneHProgressBar progressBar = new SiticoneHProgressBar();<br>progressBar.CornerRadiusTopLeft = 20;<br>progressBar.CornerRadiusTopRight = 20;<br>progressBar.CornerRadiusBottomLeft = 10;<br>progressBar.CornerRadiusBottomRight = 10;<br>this.Controls.Add(progressBar);<br>
Perfectly Circular Control	To provide a circular progress bar by enabling MakeRadial, which automatically sets each corner to form a circle.	csharp<br>// Create a perfectly circular progress bar<br>SiticoneHProgressBar progressBar = new SiticoneHProgressBar();<br>progressBar.MakeRadial = true;<br>progressBar.Size = new Size(100, 100);<br>this.Controls.Add(progressBar);<br>
Responsive Design	When designing a responsive UI, ensure that the rounded corners adjust gracefully as the control is resized.	csharp<br>// Dynamic resizing example<br>SiticoneHProgressBar progressBar = new SiticoneHProgressBar();<br>progressBar.MakeRadial = true;<br>progressBar.Dock = DockStyle.Fill;<br>this.Controls.Add(progressBar);<br>

Code Example and Demo

Below is an extensive example demonstrating how to integrate the Rounded Corners & Shape Customization feature in a simple WinForms application:

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

namespace ProgressBarDemo
{
    public class MainForm : Form
    {
        private SiticoneHProgressBar progressBar;
        private Button toggleRadialButton;

        public MainForm()
        {
            // Initialize the form
            Text = "Progress Bar Rounded Corners Demo";
            Size = new Size(400, 200);

            // Initialize the progress bar
            progressBar = new SiticoneHProgressBar()
            {
                Location = new Point(50, 50),
                Size = new Size(300, 30),
                // Custom corner radii for a unique look
                CornerRadiusTopLeft = 20,
                CornerRadiusTopRight = 10,
                CornerRadiusBottomLeft = 10,
                CornerRadiusBottomRight = 20,
                // Initially disable automatic radial mode
                MakeRadial = false,
                Value = 50  // Set an initial value for demonstration
            };

            // Initialize a button to toggle MakeRadial
            toggleRadialButton = new Button()
            {
                Text = "Toggle Circular",
                Location = new Point(150, 100),
                AutoSize = true
            };
            toggleRadialButton.Click += ToggleRadialButton_Click;

            // Add controls to the form
            Controls.Add(progressBar);
            Controls.Add(toggleRadialButton);
        }

        private void ToggleRadialButton_Click(object sender, EventArgs e)
        {
            // Toggle the MakeRadial property to switch between custom and perfectly circular corners
            progressBar.MakeRadial = !progressBar.MakeRadial;
        }

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

Review

Aspect	Evaluation
Flexibility	The feature provides a high level of customization for each corner, making it adaptable to many design requirements.
Ease of Integration	With properties that automatically update the control’s region on change, integrating rounded corners is straightforward.
Visual Impact	The ability to toggle between custom corner settings and a perfectly circular shape (MakeRadial) greatly enhances UI design possibilities.

---

Summary

The Rounded Corners & Shape Customization feature of the progress bar control allows developers to tailor the appearance of each corner through individual radius properties and an option for a fully circular appearance via the MakeRadial property. This ensures that the control can be seamlessly integrated into various design themes, offering both flexibility and a high level of visual polish.

Troubleshooting Tips

Tip	Description
Verify Property Values	Ensure that corner radius values do not exceed half of the control’s dimensions; the control automatically clamps these values, but checking helps during debugging.
Respond to Resize Events	If the control does not appear to adjust its corners correctly, verify that the OnSizeChanged event is triggering the UpdateControlRegion method.
Use MakeRadial for Uniformity	For a truly circular appearance, always use MakeRadial and set the control's size to a square dimension.
