## Description

The BonoboControlFrame object is used to embed a Control. Most people will want to use BonoboWidget instead of the control frame since it provides lots of nice auxiliary features to make embedding easy.

Figure 2. The Bonobo::ControlFrame interface

The control frame is coupled to an embedded control and is used to allow the Control to communicate with its environment, particuarly getting the BonoboUIContainer for merging its menu / toolbar UI elements.

`ui_container` : | A CORBA object for the UIContainer for the container application.
`ev` : |
Returns : | the initialized BonoboControlFrame object `control_frame` that implements the Bonobo::ControlFrame CORBA service.

`control_frame` : | The BonoboControlFrame object whose control should be activated.

### bonobo_control_frame_control_deactivate ()

    void                bonobo_control_frame_control_deactivate

Proxies `state` to the control bound to `frame`.

`control_frame` : |
`state` : | A GtkStateType value, specifying the widget state to apply to the remote control.

### bonobo_control_frame_set_autostate ()
