Description

The class ole-control-pane is used to implement embedding of external components.

Note: ole-control-pane is implemented only in LispWorks for Windows. Load the functionality by (require "embed").

Note: even though it is a subclass of pinboard-layout, normally you should not use the pinboard-layout functionality when using ole-control-pane.

component-name (if non-nil) specifies the component-name of the pane, as used by component-name.

user-component (if non-nil) is a COM interface pointer of an object that supports the I-OLE-OBJECT interface, and is ready to display as described in ole-control-user-component.

save-name is used when creating the IStorage object for this component.

insert-callback (if non-nil) is a function that takes a single argument, the pane. It is called immediately after a component was inserted into the pane. This can be used for any additional initialization that is required, for example setting the properties of the control.

close-callback (if non-nil) is a function that takes a single argument, the pane. It is called just before the component is going to be closed, and can be used to do any cleanups that may be required.

sinks is a list of sink specifications for attaching event handlers to the source interfaces of the control. Each element of sinks should be a list of the form:

( interface-name &key invoke-callback sink-class sink )

The interface-name is used to specify the name of the source interface in the control, which is either a string naming the interface or :default for the default source interface. If invoke-callback is given, then it should be a function which will be called with the pane, method-name, method-kind and arguments vector for each source event. The sink-class can be given to set the class of the internal object used for the sink interface. This is similar to calling attach-simple-sink. Alternatively, instead of calling invoke-callback , the sink can be specified directly. This is similar to calling attach-sink.

When the ole-control-pane is destroyed, the sinks are automatically detached.

There are currently three ways to insert an external component into an ole-control-pane. These are:

  1. Call ole-control-user-component, which asks the user for something to insert.
  2. Set the component-name of the pane. This can be done either via the initarg :component-name or by calling (setf component-name).
  3. Set the user-component of the pane, either via the initarg :user-component or by calling (setf ole-control-user-component).
Example
(capi:contain 
 (list 
  (make-instance 'capi:ole-control-pane
                 :component-name "OWC.Spreadsheet.9")))
