数组属性，TList，TStringList或TCollection等（Delphi Win32） [英] Array Property, TList, TStringList, or TCollection, etc (Delphi Win32)

问题描述

我正在开发各种组件，并经常遇到需要具有一对多关系的属性，即组件到属性成员。组件通常是可视化组件，但不总是，有时需要在IDE中注册（即使用属性检查器），但并不总是。我发现自己不确定在设置这些属性时使用哪个路由 - 使用数组属性，一个TList，一个TStringList，一个TCollection或者其他的东西（也许是从其中一个继承的新类）。

I am developing various components, and regularly run into the need to have a property that has a "one-to-many" relationship, component-to-property-member. The components are often visual components, but not always, and sometimes need to be registered with the IDE (i.e. use the Property Inspector), but not always. I find myself unsure of which route to take when setting up these properties -- using an array property, a TList, a TStringList, a TCollection, or something else altogether (perhaps a new class that inherits from one of those).

在哪里/哪里使用什么最佳做法/指南？

What are the "best practices" / guidelines for which to use when / where?

推荐答案

如果它们是属性，则可以从TCollection下降，然后IDE和Object Inspector将通过TCollection属性编辑器自动为它们提供支持。

If they are properties, you can descend from TCollection, and then the IDE and Object Inspector will automatically provide support for them via the TCollection Property editor.
