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 com: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:
:component-name
or by calling (setf component-name)
.:user-component
or by calling (setf ole-control-user-component)
.
(capi:contain (list (make-instance 'capi:ole-control-pane :component-name "OWC.Spreadsheet.9")))
