DrawGUI.Icon.Unity

Static icon accessor that provides ~28 built-in Unity Editor textures as readonly fields. Icons are loaded once at class initialization via EditorGUIUtility.FindTexture (by internal name) or EditorGUIUtility.IconContent (by icon content key). No caching layer — Unity manages the underlying textures.

Definition

Namespace: Paragon.Editor Assembly: Editor assembly

public static partial class DrawGUI

Nesting: DrawGUI → Icon → Unity

Texture Fields (via IconContent)

These use EditorGUIUtility.IconContent(name).image and return Texture (base type, not Texture2D):

Field	Icon Content Key	Description
ScriptableObject	ScriptableObject Icon	ScriptableObject type icon
Warning	Warning	Warning triangle
Loading	Loading	Loading spinner
Preset	Preset.Context	Preset context menu icon

Common Pitfalls

Some fields return Texture, not Texture2D The IconContent-based fields (ScriptableObject, Warning, Loading, Preset) return Texture because IconContent.image returns the base Texture type. Cast to Texture2D if needed, but note that some may actually be RenderTexture instances.

Internal names may change between Unity versions The string identifiers passed to FindTexture (e.g., "Grid.PaintTool", "d_winbtn_graph_close_h") are Unity's internal resource names and may change across Unity versions. If an icon is missing after a Unity upgrade, it returns null.

Dark theme prefix Some icons use the d_ prefix (e.g., d_Scene, d_BuildSettings.Web.Small) which loads the dark theme variant. These may look incorrect on Unity Personal (light theme). Consider using Paragon or SDF icons for theme-adaptive needs.

Readonly fields load at class init All fields are static readonly, meaning they load the first time the Unity class is accessed. If any FindTexture call returns null (icon not found), the field will be null for the entire session.

Examples

Using Unity icons in custom editor

using Paragon.Editor;

// Toolbar with built-in Unity icons
EditorGUILayout.BeginHorizontal(EditorStyles.toolbar);
if (GUILayout.Button(DrawGUI.Icon.Unity.Add, EditorStyles.toolbarButton, GUILayout.Width(24)))
{
    AddItem();
}
if (GUILayout.Button(DrawGUI.Icon.Unity.Trash, EditorStyles.toolbarButton, GUILayout.Width(24)))
{
    DeleteItem();
}
if (GUILayout.Button(DrawGUI.Icon.Unity.Refresh, EditorStyles.toolbarButton, GUILayout.Width(24)))
{
    RefreshList();
}
EditorGUILayout.EndHorizontal();
