Theme and Appearance

This feature manages the form’s visual styling by applying theme variants and associated color palettes across the title bar, control buttons, and general background.

Overview

This section details the properties and behaviors that control the overall visual appearance of the form. The theme functionality centers around the ThemeVariant property, which applies a set of theme colors to multiple elements including the title bar, control buttons, and background. By selecting a theme variant (for example, dark or light), the form’s colors are automatically updated, ensuring consistency across the interface.

Key Points

Aspect	Details	Default Value (Sample)	Example Value
ThemeVariant	Specifies a detailed theme variant that controls the form’s color scheme and visual styling.	DarkDefault (or a theme default)	LightDefault, CustomDark, etc.
Global Color Settings	Theme application automatically sets colors for the title bar, control buttons, and background.	Values defined in ThemesCollection	Customized color palette as defined in ThemesCollection
Synchronization	Changing the theme variant triggers an immediate update and redraw of the form’s visual elements.	Automatic update on property set	Instant visual refresh upon theme change

---

Best Practices

Recommendation	Explanation	Example in Code
Use ThemeVariant for consistency	Apply a pre-defined theme variant to ensure a uniform and professional appearance throughout the app.	myForm.ThemeVariant = FormThemeVariant.LightDefault;
Combine manual customization with themes	While themes provide a base set of colors, adjust specific color properties only if needed for branding.	myForm.TitleBarBackColor = Color.DodgerBlue; (after theme application)
Test across multiple displays	Ensure that theme colors and scaling appear correctly on different monitors and DPI settings.	Verify appearance on both high-DPI and standard screens.

---

Common Pitfalls

Issue	Cause	Prevention/Remedy
Inconsistent color application	Overriding theme-applied colors without coordinating with the theme’s palette.	Update custom colors only when necessary and after the theme is applied.
Delayed visual updates	Changing the ThemeVariant property after the form is already rendered might require an explicit redraw.	Call Invalidate() on the form or use Application.DoEvents() if needed.
Clashing with manual settings	Manually set colors may conflict with those provided by the theme variant.	Decide on a base theme first, then apply minor adjustments if needed.

Usage Scenarios

Scenario	How It Works	Sample Code
Standard Application Theming	Developers apply a theme variant to give the application a consistent dark or light look.	csharp\nvar myForm = new SiticoneForm {\n ThemeVariant = FormThemeVariant.DarkDefault\n};\nApplication.Run(myForm);
Brand Customization with Overrides	A base theme is applied, and specific color properties are overridden to match company branding.	csharp\nvar myForm = new SiticoneForm {\n ThemeVariant = FormThemeVariant.LightDefault,\n TitleBarBackColor = Color.DodgerBlue,\n TitleBarForeColor = Color.White\n};\nApplication.Run(myForm);
Responsive Visual Updates	Changing the theme at runtime immediately updates the form’s appearance, useful for user-selectable themes.	csharp\nmyForm.ThemeVariant = FormThemeVariant.LightDefault;\nmyForm.Invalidate(true);

---

Real Life Usage Scenarios

Scenario	Explanation	How to Implement
Enterprise Applications	Maintain a corporate color scheme across all forms by applying a custom theme variant.	Create a custom theme in ThemesCollection and set myForm.ThemeVariant to that custom variant.
Multi-User Applications with Theme Options	Allow users to select between light and dark modes from settings; theme changes reflect immediately.	Provide a settings dialog that changes ThemeVariant based on user selection and refreshes the UI.
Accessibility-Oriented Designs	Adjust color contrasts via theme variants to meet accessibility standards (e.g., high contrast themes).	Use a high-contrast theme variant and allow further customization if needed.

---

Troubleshooting Tips

Problem	Potential Cause	Suggested Fix
Theme changes not reflecting	The form may not be invalidating/redrawing properly after theme change.	Explicitly call Invalidate(true) after setting a new ThemeVariant.
Overridden colors conflicting	Manual color settings might conflict with theme defaults.	Apply theme changes first, then adjust only specific colors that require manual override.
Visual artifacts on high-DPI screens	Scaling issues might occur if icon sizes or fonts are not adjusted after theme application.	Ensure that DPI scaling is taken into account by using dynamic scaling for IconSize and font properties.

Review

Aspect	Notes
Consistency	The Theme & Appearance feature provides a centralized way to ensure all UI elements adhere to a chosen color scheme.
Flexibility	Developers can apply a full theme variant while still retaining the option to override individual properties.
Ease of Integration	Changing the theme is as simple as setting a property, making it easy to adapt the UI for different user preferences.

---

Summary

Summary Point	Description
Unified Styling	ThemeVariant allows developers to set a cohesive color palette across the entire form with one property.
Customization with Flexibility	While a base theme is applied, manual adjustments allow for fine-tuning and branding.
Immediate Visual Feedback	Changing the theme at runtime refreshes the UI, providing a dynamic and responsive user experience.

Additional Code Example

Below is a complete integration sample demonstrating how to initialize a SiticoneForm with customized theme and appearance settings:

using System;
using System.Drawing;
using System.Windows.Forms;
using SiticoneNetFrameworkUI; // Ensure the namespace is referenced correctly

public class MainForm
{
    public static void Main()
    {
        // Initialize the form with a base theme variant.
        var myForm = new SiticoneForm
        {
            FormTitle = "My Themed Application",
            ThemeVariant = FormThemeVariant.DarkDefault,
            // Optionally override specific theme colors after the base theme is applied.
            TitleBarBackColor = Color.FromArgb(45, 45, 48),
            TitleBarForeColor = Color.White,
            // Adjust control box button colors if needed
            CloseButtonHoverForeColor = Color.Red,
            RotateCloseIconOnHover = true,
        };

        // Optional: Subscribe to an event to see when theme changes might trigger a refresh.
        myForm.Load += (sender, e) =>
        {
            Console.WriteLine("Form loaded with the selected theme.");
        };

        Application.Run(myForm);
    }
}
