# Editor.PanelWindow.DropShadow

```csharp
bool DropShadow { get; set; }
```

Whether the compositor draws its shadow around the window. A decorated window has one from
its frame; a borderless window or a popup has to ask, and both do by default.

Declared in [Editor.PanelWindow](/api/Editor.PanelWindow).
Assembly: `Sandbox.Tools`.
