StyleWithBorder

DrawGUI scope that temporarily overrides a GUIStyle's border (RectOffset) for the duration of a using block. The original border values are captured on construction and restored on disposal.

Definition

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

public static partial class DrawGUI
{
    public static Scope StyleWithBorder(GUIStyle style, int? left = null, int? right = null, int? top = null, int? bottom = null)
    public static Scope StyleWithBorder(this Scope scope, GUIStyle style, int? left = null, int? right = null, int? top = null, int? bottom = null)

    private class StyleWithBorderScope : Scope
}

Remarks

The border property of a GUIStyle controls the non-stretchable border regions of a 9-sliced background image. This scope allows temporarily changing border values without permanently modifying the style.

Selective Override

Parameters are nullable (int?). Only non-null values override the corresponding edge. Null parameters keep the style's current border value for that edge.

Save/Restore Pattern

1. Constructor — captures the original border as a new RectOffset, computes the scoped RectOffset

2. OnBegin — sets style.border to the scoped values

3. OnEnd — restores style.border to the original values

Quick Lookup

Goal	How
Override all borders	DrawGUI.StyleWithBorder(style, 2, 2, 2, 2)
Override left only	DrawGUI.StyleWithBorder(style, left: 10)
Chain onto scope	scope.StyleWithBorder(style, top: 5, bottom: 5)

Factory Methods

Standalone

public static Scope StyleWithBorder(GUIStyle style, int? left = null, int? right = null, int? top = null, int? bottom = null)

Extension (Chaining)

public static Scope StyleWithBorder(this Scope scope, GUIStyle style, int? left = null, int? right = null, int? top = null, int? bottom = null)

Parameter	Type	Default	Description
style	GUIStyle	—	The style whose border to temporarily modify
left	int?	null	Left border override (null = keep original)
right	int?	null	Right border override (null = keep original)
top	int?	null	Top border override (null = keep original)
bottom	int?	null	Bottom border override (null = keep original)

StyleWithBorderScope (private)

Member	Description
style	GUIStyle — the style being modified
originalRectOffset	RectOffset — captured original style.border values
scopedRectOffset	RectOffset — the computed override values
OnBegin()	Sets style.border = scopedRectOffset
OnEnd()	Sets style.border = originalRectOffset

Common Pitfalls

Shared style mutation GUIStyle objects in Unity are reference types. If the same style instance is used elsewhere during the scope's lifetime, those usages will see the modified border values. This is by design — the scope restores the original on disposal.

Examples

Removing Border for a Single Draw

using static Paragon.Editor.DrawGUI;

// Temporarily remove all borders from the box style
using (StyleWithBorder(Style.Box, 0, 0, 0, 0))
{
    using (VerticalLayout(Style.Box))
    {
        Label("This box has no 9-slice border");
    }
}
// Style.Box.border is now restored
