Theme Integration

This feature enables the control to respond to system theme changes and adjust its appearance accordingly, ensuring seamless integration with applications that support light/dark modes, etc.

Overview

The Theme Integration feature allows the SiticoneImageButton control to track and react to system theme changes by monitoring the Windows registry for theme preferences. When enabled via the TrackSystemTheme property, the control updates its CurrentSystemTheme property and fires a SystemThemeChanged event, providing developers with the opportunity to apply custom styling or behavior based on whether the system is in light or dark mode.


Key Points

Aspect
Description

TrackSystemTheme

Enables or disables the automatic tracking of system theme changes; when true, the control listens for changes to the system's theme preferences.

CurrentSystemTheme

A read-only property that reflects the current system theme (e.g., Dark or Light) based on the user's Windows settings.

SystemThemeChanged Event

Fires whenever the system theme changes, allowing developers to implement custom responses or adjustments in real time.


Best Practices

Best Practice Area
Recommendation

Enable Theme Tracking

Set TrackSystemTheme to true when your application design needs to adapt automatically to user preferences, ensuring a consistent look across all controls.

Subscribe to Events

Always subscribe to the SystemThemeChanged event if you need to perform additional styling or logic when the theme changes, ensuring your UI elements remain in sync with system preferences.

Minimal Impact on Performance

As theme tracking relies on monitoring system events and the registry, ensure that any event handlers you attach are optimized to avoid performance bottlenecks in your application.


Common Pitfalls

Pitfall Area
Description
Mitigation Strategy

Overcomplicated Theme Logic

Overly complex logic in the SystemThemeChanged event handler may lead to UI freezes or inconsistent behavior if not properly managed.

Keep theme change handlers simple and offload heavy processing to background tasks if necessary.

Ignoring Fallbacks

Failing to consider a fallback style when theme detection fails (e.g., registry access issues) might result in unexpected appearance.

Implement sensible default styles and handle exceptions within theme tracking logic gracefully.

Inconsistent Theme Updates

In some cases, not updating all affected UI components in response to a theme change may lead to a mixed visual experience across the application.

Ensure all controls that support theme integration update consistently when the system theme changes.


Usage Scenarios

Scenario
Explanation
Recommended Settings

Adaptive User Interfaces

For applications that support light and dark themes, enable TrackSystemTheme to automatically adjust the control’s appearance according to the system settings.

Set TrackSystemTheme to true; subscribe to the SystemThemeChanged event to apply custom theme-specific logic.

Custom Theme Responses

When specific actions or UI adjustments are required upon a theme change, utilize the CurrentSystemTheme property and SystemThemeChanged event to trigger these changes.

Use a simple event handler to detect theme changes and update other UI components accordingly.

Consistent Styling Across Controls

In a complex UI where multiple controls need to respond uniformly to system theme changes, leveraging this feature ensures that all theme-aware controls remain consistent.

Ensure that all theme-sensitive controls have TrackSystemTheme enabled and share similar event-handling logic.


Code Examples

Example 1: Enabling Theme Integration with Default Settings

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

public class ThemeDemoForm : Form
{
    private SiticoneImageButton imageButton;

    public ThemeDemoForm()
    {
        // Initialize the image button with theme integration enabled
        imageButton = new SiticoneImageButton
        {
            Size = new Size(100, 100),
            Location = new Point(50, 50),
            // Enable tracking of system theme changes
            TrackSystemTheme = true
        };

        // Subscribe to the SystemThemeChanged event to handle theme updates
        imageButton.SystemThemeChanged += OnSystemThemeChanged;

        Controls.Add(imageButton);
    }

    // Event handler to respond to theme changes
    private void OnSystemThemeChanged(object sender, SystemThemeChangedEventArgs e)
    {
        // Example: Update the border color based on the current system theme
        if (e.NewTheme == SystemTheme.Dark)
        {
            imageButton.BorderColor = Color.White;
        }
        else // SystemTheme.Light or Custom
        {
            imageButton.BorderColor = Color.Black;
        }

        // Additional customizations can be applied here
        MessageBox.Show("System theme changed to: " + e.NewTheme);
    }

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

Example 2: Conditional Styling Based on System Theme

// Assume imageButton is already added to your form and theme tracking is enabled.
private void ApplyThemeBasedStyling(SiticoneImageButton imageButton)
{
    // Check the current system theme
    if (imageButton.CurrentSystemTheme == SystemTheme.Dark)
    {
        imageButton.BackgroundFillColor = Color.FromArgb(30, 30, 30);
        imageButton.BorderColor = Color.White;
    }
    else // Light or Custom theme
    {
        imageButton.BackgroundFillColor = Color.White;
        imageButton.BorderColor = Color.Black;
    }
}

Additional Considerations

Consideration
Details

Handling Registry Access Issues

The control attempts to read the Windows registry to determine the system theme; ensure that your application has the necessary permissions or provide appropriate fallbacks.

Testing Across Environments

Test theme integration on various Windows versions and configurations to verify that the registry values are read correctly and the theme updates occur as expected.

Unified Theme Handling

Consider creating a centralized theme manager in your application to propagate theme changes across multiple controls and forms.


Review

The Theme Integration feature enhances the usability of the SiticoneImageButton control by enabling it to adapt dynamically to system theme changes. This ensures that applications remain visually consistent with user preferences for light or dark modes. By leveraging the TrackSystemTheme property, the control automatically updates its appearance, and the SystemThemeChanged event provides a hook for custom theme-related logic.


Summary

The Theme Integration feature of the SiticoneImageButton control provides a robust mechanism for adapting the control's appearance based on the current system theme. With properties like TrackSystemTheme and CurrentSystemTheme, as well as the SystemThemeChanged event, developers can ensure that their applications respond dynamically to user settings, maintaining a consistent and visually appealing interface across different theme modes.
