All Implemented Interfaces:

public class OleControlSite
extends OleClientSite

OleControlSite provides a site to manage an embedded ActiveX Control within a container.

In addition to the behaviour provided by OleClientSite, this object provides the following:

• events from the ActiveX control
• notification of property changes from the ActiveX control
• simplified access to well known properties of the ActiveX Control (e.g. font, background color)
• expose ambient properties of the container to the ActiveX Control

This object implements the OLE Interfaces IOleControlSite, IDispatch, and IPropertyNotifySink.

Note that although this class is a subclass of Composite, it does not make sense to add Control children to it, or set a layout on it.

style - the bitwise OR'ing of widget styles

file - the file that is to be opened in this OLE Document

Throws:

IllegalArgumentException -

• ERROR_NULL_ARGUMENT when the parent is null
• ERROR_INVALID_ARGUMENT when the parent is not an OleFrame

SWTException -

• ERROR_THREAD_INVALID_ACCESS when called from the wrong thread
• ERROR_CANNOT_CREATE_OBJECT when failed to create OLE Object
• ERROR_CANNOT_OPEN_FILE when failed to open file
• ERROR_INTERFACE_NOT_FOUND when unable to create callbacks for OLE Interfaces
• ERROR_INVALID_CLASSID
