观察者在TComponent的财产 [英] Observers property in TComponent

问题描述

Hi Delphi XE2 TComponent 有一个新的观察者属性。不幸的是，这个帮助条目是空的。有没有人知道这个新的财产是好的，如何使用它？
编辑：我知道它与LiveBindings有关，但我很想知道一些，因为我没有访问XE2源代码，我无法调查自己。

Hi Delphi XE2 TComponent has a new "Observers" property. Unfortunately the help entries for this are empty. Does anybody know what this new property is good for and how to use it? Well i know that it is related to LiveBindings, but I would love to know a bit more about it, and since I have no access to XE2 source code, I can't investigate myself.

推荐答案

Delphi XE7文档现在更深入了解 Observer s：

The Delphi XE7 documentation now goes much deeper into the details of the Observers:

观察者是一个只读属性，返回添加的TObservers
是TComponent，以便使用
观察者提供的通知与LiveBindings或开发人员自己的
目的。

Observers is a read-only property that returns the TObservers added to the TComponent, in order to use the notifications provided by the observers either with LiveBindings or for the developers' own purposes.

请注意，观察者在Fringe中可以看到许多模式相关事件的场景。

Note that the Observer in Fringe can be seen on the scene of many Pattern-related events.

旁注：

观察者也可以检测到一个 EProgrammerNotFound异常必须由RTL抛出。

Observers might also be able to detect situations where a EProgrammerNotFound exception must be thrown by the RTL.
