BoxHeader

Scope that wraps content in a Sirenix box header region via SirenixEditorGUI.BeginBoxHeader/EndBoxHeader. Used inside a Box scope to create a custom header area with arbitrary controls (buttons, labels, toggles, etc.).

Definition

Namespace: Paragon.Editor Assembly: Paragon.Editor.dll

public static partial class DrawGUI
{
    // Factory method
    public static Scope BoxHeader()

    // Extension method (chaining)
    public static Scope BoxHeader(this Scope scope)

    // Implementation
    private class BoxHeaderScope : Scope
}

Remarks

BoxHeader creates a styled header bar inside a Sirenix box. Unlike Box("label") which draws a simple text header, BoxHeader lets you place any IMGUI content in the header — buttons, toggles, horizontal layouts, icons, etc.

Must be used inside a Box scope. BoxHeader draws a header region that is visually integrated with Sirenix's box styling. Using it outside a Box() scope will produce incorrect visual results.

Factory Methods

BoxHeader

Creates a box header region scope. Takes no parameters — the header styling is handled entirely by Sirenix.

public static Scope BoxHeader()
public static Scope BoxHeader(this Scope scope)

Examples

Custom Header with Button

using static Paragon.Editor.DrawGUI;

using (Box())
{
    using (BoxHeader())
    {
        using (HorizontalLayout())
        {
            Label("Components", Style.LabelBold);
            FlexibleSpace();
            if (Button("+", Style.Button, GUILayout.Width(24)))
            {
                AddComponent();
            }
        }
    }

    // Box body content
    foreach (var component in components)
    {
        Label(component.Name);
    }
}

Header with Toggle

using static Paragon.Editor.DrawGUI;

using (Box())
{
    using (BoxHeader())
    {
        CheckBox(ref isEnabled, "Enable Feature");
    }

    using (ReadonlyIf(!isEnabled))
    {
        Label("Feature settings...");
    }
}

Chained Box + BoxHeader

using static Paragon.Editor.DrawGUI;

using (Box().BoxHeader())
{
    Label("This is in the header");
}
// Note: body content would need a separate scope after BoxHeader ends
