DocumentLockModeChangedEventArgs.Veto Method
Description
This function can be called during a DocumentLockModeChanged callback if it is a callback for a lock request. The result will be that the lock request will be vetoed, which normally means that the command will be canceled before it can start. When this function is called, DocumentLockModeChangeVetoed will be sent.
It is only active during DocumentLockModeChanged in case the receiver of the call needs to make any changes in the document before deciding whether to veto or not. By waiting until the changed callback, the document will be currently locked when the ability to veto is given. This is necessary because it is not possible to change the document's lock status from within any of these callbacks.
Visual Basic
Public Function Veto() As void
C#
public void Veto();

在lisp中如何调用？？请各位给与支持，谢谢。
这个veto方法，或者叫函数，能在LISP里面调用，从而在特定场合下取消执行的命令,按照自己的程序执行。 直接vlisp的反应器就可以实现，不过好像不能点击实体对象本身 我爱lisp 发表于 2023-10-31 11:06

这个回调函数如何修改？才能把执行中的指令给取消掉，从而执行自定义函数
