Supported Platforms: Windows only
(vlr-xref-reactor data callbacks)
Type: Integer, Real, String, List, VLA-object, Safearray, Variant, T, or nil
Any AutoLISP data to be associated with the reactor object; otherwise nil if no data.
Type: List
A list of pairs of the following form:
(event-name . callback_function)
event-name is one of the following XREF reactor events:
XREF reactor events |

Event name |
Description |
:VLR-beginAttach |
An xref is about to be attached. |
:VLR-otherAttach |
An external reference is being added to the drawing database. This event occurs after objects are cloned, but before any translation. This callback function is sent just after beginDeepCloneXlation notification, but occurs only for the xref attach process. |
:VLR-abortAttach |
An xref attach operation was terminated before successful completion. |
:VLR-endAttach |
An xref attach operation completed successfully. |
:VLR-redirected |
An object ID in the xref drawing is being modified to point to the associated object in the drawing being referenced. |
:VLR-comandeered |
The object ID of the object is being appended to the symbol table of the drawing being xrefed into. |
:VLR-beginRestore |
An existing xref is about to be resolved (typically when a drawing with xrefs is loading). |
:VLR-abortRestore |
An xref unload or reload was terminated before successful completion. |
:VLR-endRestore |
An existing xref has been resolved (typically when a drawing with xrefs has completed loading). |
:VLR-xrefSubcommandBindItem |
The BIND subcommand of XREF was invoked, or a preexisting xref is being bound. Note: The BIND subcommand is interactive and triggers multiple events.
|
:VLR-xrefSubcommandAttachItem |
The ATTACH subcommand of XREF was invoked, or a preexisting xref is being resolved. Note: The ATTACH subcommand is interactive and triggers multiple events.
|
:VLR-xrefSubcommandOverlayItem |
The OVERLAY subcommand of XREF was invoked, or a preexisting xref is being resolved. Note: The OVERLAY subcommand is interactive and triggers multiple events.
|
:VLR-xrefSubcommandDetachItem |
The DETACH subcommand of XREF was invoked. Note: The DETACH subcommand is interactive and triggers multiple events.
|
:VLR-xrefSubcommandPathItem |
The PATH subcommand of XREF was invoked. Note: The PATH subcommand is interactive and triggers multiple events.
|
:VLR-xrefSubcommandReloadItem |
The RELOAD subcommand of XREF was invoked, or a preexisting xref is being reloaded. Note: The RELOAD subcommand is interactive and triggers multiple events.
|
:VLR-xrefSubcommandUnloadItem |
The UNLOAD subcommand of XREF was invoked, or a preexisting xref is being unloaded. |
callback_function is a symbol representing a function to be called when the event fires. Each callback function accepts two arguments:
reactor_object -- The VLR object that called the callback function.
list -- A list of extra data elements associated with the particular event. The contents of this list for particular events are shown in the “XREF reactor callback data” table.
