# IUserInputController Interface
 
This interface is implemented by all controls that can manage user input (such as mouse events) of the [ViewerBase](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_ViewerBase.htm.md) control.
 
**Namespace:** [Aurigma.GraphicsMill.WinControls](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_WinControls.htm.md)
 **Assembly:** Aurigma.GraphicsMill.WinControls (in Aurigma.GraphicsMill.WinControls.dll)
 
## Syntax
  
```
Public Interface IUserInputController
```
 
```csharp
public interface IUserInputController
```
 
## Remarks
  
Examples of the controls which should implement this interface are the rubberbands and the navigators. You can inherit from the [UserInputController](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_UserInputController.htm.md) class which contains the partial implementation for this interface.
