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.

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.

Example 1. A nice use of a BonoboControlFrame

BonoboWidget *
bonobo_widget_construct_control_from_objref (BonoboWidget      *bw,
					     Bonobo_Control     control,
					     Bonobo_UIContainer uic)
{
	GtkWidget    *control_frame_widget;

	/*
	 * Create a local ControlFrame for it.
	 */
	bw->priv->control_frame = bonobo_control_frame_new (uic);

	bonobo_control_frame_bind_to_control (bw->priv->control_frame, control);

	...

	bonobo_control_frame_set_autoactivate (bw->priv->control_frame, TRUE);

	/*
	 * Grab the actual widget which visually contains the remote
	 * Control.  This is a GtkSocket, in reality.
	 */
	control_frame_widget = bonobo_control_frame_get_widget (bw->priv->control_frame);

	/*
	 * Now stick it into this BonoboWidget.
	 */
	gtk_container_add (GTK_CONTAINER (bw),
			   control_frame_widget);

	/*
	 * Always remember to show the widget before reporting bugs.
	 */
	gtk_widget_show (control_frame_widget);

	if (uic != CORBA_OBJECT_NIL)
		bw->priv->uic = bonobo_object_dup_ref (uic, NULL);

	return bw;
}

bonobo_control_frame_new ()

BonoboControlFrame* bonobo_control_frame_new
                                            (Bonobo_UIContainer ui_container);

ui_container : The Bonobo_UIContainer for the container application.
Returns : BonoboControlFrame object that implements the Bonobo::ControlFrame CORBA service.

bonobo_control_frame_get_widget ()

GtkWidget*  bonobo_control_frame_get_widget (BonoboControlFrame *frame);

Use this function when you want to embed a BonoboControl into your container's widget hierarchy. Once you have bound the BonoboControlFrame to a remote BonoboControl, place the widget returned by bonobo_control_frame_get_widget() into your widget hierarchy and the control will appear in your application.

frame : The BonoboControlFrame whose widget is being requested.a
Returns : A GtkWidget which has the remote BonoboControl physically inside it.

bonobo_control_frame_set_ui_container ()

void        bonobo_control_frame_set_ui_container

                                             Bonobo_UIContainer uic);

Associates a new Bonobo_UIContainer object with this ControlFrame. This is only allowed while the Control is deactivated.

control_frame : A BonoboControlFrame object.
uic : A Bonobo_UIContainer object reference.

bonobo_control_frame_control_activate ()

void        bonobo_control_frame_control_activate
                                            (BonoboControlFrame *control_frame);

Activates the BonoboControl embedded in control_frame by calling the activate() Bonobo_Control interface method on it.

control_frame : The BonoboControlFrame object whose control should be activated.

bonobo_control_frame_control_deactivate ()

void        bonobo_control_frame_control_deactivate

Modifies the autoactivate behavior of control_frame. If control_frame is set to autoactivate, then it will automatically send an "activate" message to the Control to which it is bound when it gets a focus-in event, and a "deactivate" message when it gets a focus-out event. Autoactivation is off by default.
