Corner Radius Customization

Corner Radius Customization allows developers to adjust the rounding of each corner of the progress bar, enabling a more refined and tailored look that can match the application's overall design.

Overview

The Corner Radius Customization feature provides control over the curvature of the progress bar's corners. With properties to individually set the radii for the top-left, top-right, bottom-right, and bottom-left corners, as well as a synchronization option to apply a uniform radius, this feature allows for flexible styling that can adapt to various design requirements.

Feature Details

Property	Type	Default Value	Description
TopLeftRadius	float	0	Sets the radius for the top-left corner of the progress bar.
TopRightRadius	float	0	Sets the radius for the top-right corner of the progress bar.
BottomRightRadius	float	0	Sets the radius for the bottom-right corner of the progress bar.
BottomLeftRadius	float	0	Sets the radius for the bottom-left corner of the progress bar.
SyncCornerRadius	bool	false	When enabled, synchronizes all corner radii so that updating one updates all four corners.
SetCornerRadii()	Method	N/A	Allows setting all four corner radii at once without relying on the synchronization feature.

---

Key Points

Key Point	Explanation
Individual Control	Each corner can be customized separately to create unique shapes and visual styles.
Uniform Appearance Option	The synchronization feature (SyncCornerRadius) simplifies the process of applying a consistent radius to all corners.
Dynamic Updates	Changes to any of the radius properties trigger an immediate redraw, ensuring the UI reflects the new settings promptly.

---

Best Practices

Best Practice	Details
Use Consistent Values for Uniformity	When a uniform appearance is desired, enable SyncCornerRadius to reduce code complexity and maintain consistency.
Test Across Different Sizes	Verify the appearance of rounded corners at various control sizes to ensure the design scales appropriately.
Consider the Overall UI Theme	Adjust the corner radii to complement the overall design language of your application, whether modern or traditional.

---

Common Pitfalls

Pitfall	Explanation
Inconsistent Appearance	Changing one corner’s radius without enabling SyncCornerRadius may result in a disjointed look if not intentionally styled.
Overly Large Radii	Setting a radius that is too large relative to the control's size may distort the progress bar or hide important visual cues.
Neglecting Dynamic Redraws	Failing to update the control’s appearance immediately after changing radius properties might lead to a mismatch between design expectations and the rendered output.

---

Usage Scenarios

Scenario	How to Apply Corner Radius Customization
Modern Flat UI Design	Use a moderate uniform radius (e.g., 5-10 pixels) to achieve a modern, flat design that is visually appealing and in line with contemporary UI trends.
Custom Shaped Controls	Customize each corner individually to create non-standard shapes that stand out and add a unique visual identity to the application.
Responsive Design Adjustments	Dynamically adjust corner radii based on control size or window dimensions to ensure a consistent look across different resolutions and devices.

Code Examples

Example 1: Uniform Corner Radius Using SyncCornerRadius

This example demonstrates how to apply a uniform radius to all corners using the synchronization property.

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

public class UniformCornerForm : Form
{
    private SiticoneHLineProgress progressBar;

    public UniformCornerForm()
    {
        InitializeComponent();
        InitializeProgressBar();
    }

    private void InitializeComponent()
    {
        this.Text = "Uniform Corner Radius Demo";
        this.Size = new Size(400, 200);
    }

    private void InitializeProgressBar()
    {
        progressBar = new SiticoneHLineProgress
        {
            Minimum = 0,
            Maximum = 100,
            Value = 75,
            Location = new Point(20, 50),
            Size = new Size(350, 14),
            TopLeftRadius = 8,  // Set initial radius for one corner
            SyncCornerRadius = true // Enable synchronization to apply the same radius to all corners
        };

        this.Controls.Add(progressBar);
    }

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

Example 2: Custom Individual Corner Radii

This example shows how to set each corner's radius individually, allowing for a custom-shaped progress bar.

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

public class CustomCornerForm : Form
{
    private SiticoneHLineProgress progressBar;

    public CustomCornerForm()
    {
        InitializeComponent();
        InitializeProgressBar();
    }

    private void InitializeComponent()
    {
        this.Text = "Custom Corner Radii Demo";
        this.Size = new Size(400, 250);
    }

    private void InitializeProgressBar()
    {
        progressBar = new SiticoneHLineProgress
        {
            Minimum = 0,
            Maximum = 100,
            Value = 50,
            Location = new Point(20, 70),
            Size = new Size(350, 14),
            TopLeftRadius = 5,
            TopRightRadius = 15,
            BottomRightRadius = 10,
            BottomLeftRadius = 0,
            SyncCornerRadius = false // Disable synchronization to allow custom values per corner
        };

        this.Controls.Add(progressBar);
    }

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

Example 3: Using SetCornerRadii Method

This example demonstrates how to use the provided helper method to set all four corner radii at once.

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

public class SetCornerRadiiForm : Form
{
    private SiticoneHLineProgress progressBar;

    public SetCornerRadiiForm()
    {
        InitializeComponent();
        InitializeProgressBar();
    }

    private void InitializeComponent()
    {
        this.Text = "SetCornerRadii Method Demo";
        this.Size = new Size(400, 200);
    }

    private void InitializeProgressBar()
    {
        progressBar = new SiticoneHLineProgress
        {
            Minimum = 0,
            Maximum = 100,
            Value = 80,
            Location = new Point(20, 50),
            Size = new Size(350, 14),
            SyncCornerRadius = false // Disable sync to allow manual setting via method
        };

        // Set all corner radii to 12 using the helper method.
        progressBar.SetCornerRadii(12, 12, 12, 12);

        this.Controls.Add(progressBar);
    }

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