Implements the frame of components in an ole-control-pane.
The pane class
implements the frame of components, that is it supports the
interface. When an ole-control-pane pane is created, it looks upwards in the hierarchy of panes, and if finds an
pane it uses this as the frame. It uses the first such pane found. When the object in the ole-control-pane calls
, it gets back in the
an interface associated with this frame.
Like ole-control-doc, a
can have only one sub-pane, which itself may contain many panes.
Note that having a frame is optional, and ActiveX does not need it. It is required when embedding an application by ole-control-insert-object.
