Appearance and Styling

This feature provides extensive customization of the visual aspects of the control, allowing developers to adjust colors, textures, cursors, and panel headers to match the application's design.

Overview

The Appearance & Styling feature of the SiticoneSplitContainer control enables developers to tailor the look and feel of the splitter and panels. Through properties such as SplitterHighlightColor, EnableSplitterHighlight, SplitterTexture, and SplitterCursor, along with panel header customization via ShowPanelHeaders, Panel1Title, and Panel2Title, the control can be visually integrated into any application's theme.

Key Points

Aspect	Description
Visual Feedback	Properties like EnableSplitterHighlight and SplitterHighlightColor enhance the visual feedback during interactions.
Custom Texture	The SplitterTexture property allows the insertion of a custom image or pattern on the splitter.
Cursor Customization	The SplitterCursor property defines the cursor appearance when hovering over the splitter, aiding user intuitiveness.
Panel Header Customization	Panel headers can be enabled or hidden with ShowPanelHeaders, and their titles are customizable via Panel1Title and Panel2Title.

---

Best Practices

Recommendation	Details
Match Application Theme	Choose colors and textures that complement the overall application theme to maintain a consistent look and feel.
Use High-Quality Images	Ensure that any custom images set as textures are of high resolution to avoid visual artifacts during scaling.
Test Cursor Behavior	Verify that the custom cursor appears as expected on different operating systems and display settings.
Update Panel Headers Dynamically	If panel titles are likely to change, ensure the headers update promptly by invoking the header update methods.

---

Common Pitfalls

Pitfall	Explanation	Mitigation Strategy
Overuse of Highlights	Excessive use of highlight colors may clash with the overall design and distract users.	Use highlight colors sparingly and in line with the application's color scheme.
Inconsistent Texture Scaling	Custom textures may appear pixelated or distorted if not scaled properly.	Use high-resolution images and test with different control sizes to ensure consistent appearance.
Ignoring Accessibility Considerations	Custom headers without proper accessibility settings can lead to poor user experiences for assistive technologies.	Ensure panel headers are correctly set with accessible names and roles as part of the customization.

Usage Scenarios

Scenario	Description	Example Use Case
Theming a Custom Application	Adjust the splitter and panel header styling to match a specific theme or branding of an enterprise application.	Applying a corporate color scheme to the control with custom header texts and textures.
Enhancing User Interaction	Provide visual feedback with highlights and custom cursors when the user interacts with the splitter.	Changing the splitter highlight color when hovered to indicate interactivity.
Dynamic UI Updates	Dynamically update panel header titles based on user interactions or application state changes.	Renaming panel headers in response to selected menu options or data changes in the application.

Code Examples

1. Customizing the Splitter Appearance

This example demonstrates how to customize the splitter's appearance by setting a highlight color, a custom texture, and a specific cursor.

public class CustomAppearanceForm : Form
{
    private SiticoneSplitContainer splitContainer;

    public CustomAppearanceForm()
    {
        InitializeComponent();
        splitContainer = new SiticoneSplitContainer
        {
            Dock = DockStyle.Fill,
            // Set the color used for splitter highlight on hover
            SplitterHighlightColor = Color.DodgerBlue,
            // Enable visual highlight on splitter
            EnableSplitterHighlight = true,
            // Set a custom texture for the splitter (ensure the image resource is available)
            SplitterTexture = Image.FromFile("path_to_custom_texture.png"),
            // Customize the cursor for the splitter
            SplitterCursor = Cursors.VSplit
        };

        this.Controls.Add(splitContainer);
    }
}

2. Enabling and Customizing Panel Headers

This example illustrates how to enable panel headers and customize their titles to provide a clear visual distinction between panels.

public class PanelHeaderForm : Form
{
    private SiticoneSplitContainer splitContainer;

    public PanelHeaderForm()
    {
        InitializeComponent();
        splitContainer = new SiticoneSplitContainer
        {
            Dock = DockStyle.Fill,
            // Enable panel headers
            ShowPanelHeaders = true,
            // Set custom titles for each panel header
            Panel1Title = "Navigation",
            Panel2Title = "Details"
        };

        this.Controls.Add(splitContainer);
    }
}

3. Dynamically Updating Appearance Based on Events

This example shows how you can dynamically change the appearance of the splitter in response to a theme change event.

public class DynamicAppearanceForm : Form
{
    private SiticoneSplitContainer splitContainer;

    public DynamicAppearanceForm()
    {
        InitializeComponent();
        splitContainer = new SiticoneSplitContainer
        {
            Dock = DockStyle.Fill,
            ShowPanelHeaders = true,
            Panel1Title = "Dashboard",
            Panel2Title = "Settings",
            EnableSplitterHighlight = true
        };

        // Subscribe to system theme changes to update styling
        splitContainer.SystemThemeChanged += OnSystemThemeChanged;

        this.Controls.Add(splitContainer);
    }

    private void OnSystemThemeChanged(object sender, SiticoneSplitContainer.SystemThemeChangedEventArgs e)
    {
        // Change splitter highlight color based on system theme
        if (e.NewTheme == SiticoneSplitContainer.SystemTheme.Dark)
        {
            splitContainer.SplitterHighlightColor = Color.FromArgb(0, 122, 204);
        }
        else if (e.NewTheme == SiticoneSplitContainer.SystemTheme.Light)
        {
            splitContainer.SplitterHighlightColor = Color.DodgerBlue;
        }
        else
        {
            splitContainer.SplitterHighlightColor = Color.Gray;
        }
        splitContainer.Invalidate();
    }
}
