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

32 * <p>In addition to the behaviour provided by OleClientSite, this object provides the following:
|
|
|
33 * <ul>
|
|
|
34 * <li>events from the ActiveX control
|
|
|
35 * <li>notification of property changes from the ActiveX control
|
|
|
36 * <li>simplified access to well known properties of the ActiveX Control (e.g. font, background color)
|
|
|
37 * <li>expose ambient properties of the container to the ActiveX Control
|
|
|
38 * </ul>
|
|
|
39 *
|
|
|
40 * <p>This object implements the OLE Interfaces IOleControlSite, IDispatch, and IPropertyNotifySink.
|
|
|
41 *
|
|
|
42 * <p>Note that although this class is a subclass of <code>Composite</code>,
|
|
|
43 * it does not make sense to add <code>Control</code> children to it,
|
|
|
44 * or set a layout on it.
