Theme Application and Automation

A feature that allows developers to automatically or manually apply the current system theme to controls and forms.

Overview

This feature provides methods and properties that enable the application of the current system theme (dark or light) to individual controls or entire forms. It includes automatic application of the theme when enabled and manual methods for applying the theme, ensuring a consistent look and feel across the application.

Key Points

Aspect	Details
Methods	ApplyThemeToControl(Control control) and ApplyThemeToForm(Form form)
Properties Integration	Works in conjunction with AutoApplyTheme and TargetForm properties in the SiticoneThemeTracker component
Scope	Supports both individual controls and complete forms
Theme Customization	Adjusts background, foreground, and border colors according to the current theme

---

Best Practices

Practice	Description
Utilize AutoApplyTheme	Set AutoApplyTheme to true and assign a valid TargetForm to automatically update theme changes on the form.
Encapsulate Manual Application	When not using auto-application, encapsulate calls to ApplyThemeToControl or ApplyThemeToForm in a dedicated method.
Consistent Theme Design	Ensure that the theme colors (background, foreground, border) defined in the method match your overall design scheme.
Test Under Different System Themes	Verify the application behavior under both light and dark modes to ensure visual consistency.

---

Common Pitfalls

Pitfall	Explanation
Overriding Automatic Settings	Manually setting colors on controls that are also managed by ApplyThemeToControl may lead to inconsistent themes.
Not Setting TargetForm with AutoApplyTheme	Failing to assign a valid form to TargetForm when using AutoApplyTheme will prevent the theme from auto-applying.
Ignoring Nested Controls	Not considering that ApplyThemeToControl applies recursively to all child controls may cause missed updates.

---

Usage Scenarios

Scenario	Description
Dynamic UI Refresh	Automatically update the entire form's appearance when the system theme changes.
Manual Theme Enforcement	Manually apply theme settings to specific controls that require a custom or unique presentation.
Component-Based Theme Consistency	Ensure that all UI components maintain a consistent theme by centralizing the theme application logic.

---

Real Life Usage Scenarios

Scenario	Description
Modern Dark Mode Application	An application that shifts between light and dark modes can use ApplyThemeToForm to update the entire UI seamlessly.
Custom Control Integration	For custom controls that require a specific theme, ApplyThemeToControl can be invoked to apply the consistent theme settings.
Responsive UI Adaptation	Applications that adjust dynamically based on user preferences or system settings can benefit from the automatic theme application.

---

Troubleshooting Tips

Issue	Suggested Resolution
Form or Control Not Updating	Verify that AutoApplyTheme is enabled and that the TargetForm is correctly assigned; if using manual updates, ensure that the correct control instance is passed.
Inconsistent Color Application	Ensure that custom color settings are not conflicting with the colors applied by the theme automation logic.
Nested Controls Not Updating	Check that the recursive logic in ApplyThemeToControl is properly reaching all child controls.

Integration Example

Below is an example demonstrating how to integrate and use the Theme Application & Automation feature in a .NET WinForms application.

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

namespace ThemeApplicationDemo
{
    public partial class MainForm : Form
    {
        private SiticoneThemeTracker themeTracker;

        public MainForm()
        {
            InitializeComponent();
            InitializeThemeAutomation();
        }

        private void InitializeThemeAutomation()
        {
            // Instantiate the theme tracker and enable automatic theme application
            themeTracker = new SiticoneThemeTracker
            {
                AutoApplyTheme = true,
                TargetForm = this
            };

            // Optionally subscribe to theme changed events if additional custom actions are needed
            themeTracker.ThemeChanged += ThemeTracker_ThemeChanged;
        }

        private void ThemeTracker_ThemeChanged(object sender, ThemeChangedEventArgs e)
        {
            // Custom logic can be added here if additional processing is required
            Console.WriteLine($"Theme changed to: {e.CurrentTheme}");
        }

        // Example method for manual theme application to a specific control
        private void UpdateCustomControlTheme()
        {
            // Assume customPanel is a Panel control on the form
            themeTracker.ApplyThemeToControl(customPanel);
        }

        protected override void OnFormClosed(FormClosedEventArgs e)
        {
            // Dispose of the theme tracker to release resources
            themeTracker.Dispose();
            base.OnFormClosed(e);
        }
    }
}

Code Sample Explanation

Section	Explanation
Initialization	The SiticoneThemeTracker is instantiated, and AutoApplyTheme is set to true with TargetForm assigned to the current form.
Event Subscription	The ThemeChanged event is subscribed to for any additional custom behavior when the system theme changes.
Manual Update Method	The UpdateCustomControlTheme method demonstrates how to manually apply the theme to a specific control.
Resource Management	Disposing of the themeTracker in OnFormClosed ensures that resources are properly released.

---

Review

Aspect	Review Comments
Flexibility	Provides both automatic and manual application of theme settings for diverse UI customization needs.
Ease of Use	Clear separation between automatic application via properties and manual control application through methods.
Integration Effort	Minimal effort required to integrate with existing forms and controls by leveraging provided methods.

---

Summary

Summary Aspect	Summary Details
Functionality	Automatically or manually applies the system theme to forms and controls, ensuring a consistent UI experience.
Developer Benefits	Reduces the overhead of managing UI theme updates by encapsulating theme application logic within easy-to-use methods.
Integration Ease	Seamless integration into WinForms applications through simple property assignments and method calls.

Additional Useful Sections

Integration Checklist

Checklist Item	Status/Notes
Component Instantiation	Ensure that SiticoneThemeTracker is created and initialized.
AutoApplyTheme Setting	Confirm that AutoApplyTheme is set to true if automatic updates are desired.
TargetForm Assignment	Verify that TargetForm is correctly set to the form that should receive theme updates.
Manual Method Invocation	For custom controls, ensure that ApplyThemeToControl is called appropriately.
Resource Disposal	Confirm that Dispose() is invoked when the form is closed to prevent leaks.

FAQ

Question	Answer
How do I automatically update the form's theme?	Set AutoApplyTheme to true and assign the form to the TargetForm property.
Can I apply the theme manually to specific controls?	Yes, use the ApplyThemeToControl method to manually update the appearance of individual controls.
What should I do if my control does not update?	Verify that the control is not overridden by custom color settings and that the recursive application logic is reaching all child controls.
