Supported Platforms: Windows only

Signature

callbacks

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.
