本文介绍了Delphi中的TFrame组件，它作为容器可以嵌套在Form或其他TFrame中，并且能够保存在组件调色板上以便重复使用。创建并保存后的TFrame作为一个单元继续运行，并继承其所包含组件的变化。

Standard面板上的Frames控件

TFrame is a container for components; it can be nested within forms or other frames.

Unit

Forms

Description

When you create frames, they are implemented as descendants of TFrame.

A frame, like a form, is a container for other components. It uses the same ownership mechanism as forms for automatic instantiation and destruction of the components on it, and the same parent-child relationships for synchronization of component properties. But frames can be nested within forms or other frames, and they can be saved on the Component palette for easy reuse. After a frame is created and saved, it continues to function as a unit and to inherit changes from the components (including other frames) it contains. Moreover, an embedded frame continues to inherit changes made to the frame from which it is derived.
