推荐答案

我很确定你混淆了MDIForm容器窗口本身，你可以指定某些交互（鼠标）事件：但是，这些事件将永远不会被触发。



创建WinForm项目时，设置主要的IsMDIContainer属性（形式为''真实：它变成了一种与常规Windows形式完全不同的动物类型。



你可以与MDIForm相关的与鼠标相关的EventHandlers：如：Click，MouseDown，Leave，MouseClick，MouseMove，Enter：这些事件都不会被触发。注意：我认为你可以分配的事实在设计时Visual Studio PropertyGrid中的一个MDIContainerForm的EventHandlers一个严重的设计缺陷：在我看来，那些事件应该永远出现在PropertyGrid中的MDIContainerForm。



但是，您可以指定Keyboard EventHandlers：if你将MDIContainerForm的KeyPreview属性设置为''true：你可以为像'KeyDown这样的事件编写EventHandler，它们将被触发。



MDI架构的整个想法（如果它不是kludge）是：最终用户与MDI ChildForms 交互，而不是将他们的父表格变成MDIContainer ！



顺便说一下，MDI现在是一种古老的化石，它随着用户界面的变化而变得非常丑陋，而且它'''被Microsoft弃用。



有更好的方法来处理多个表格/ Windows！

I am pretty sure that you are confusing the MDIForm container window, itself, to which you can assign certain interaction (Mouse) Events: but, those Events will never be triggered.

When you create a WinForm Project, and set the IsMDIContainer Property of the main (start-up) Form to ''true: it becomes a really different type of "animal" than a regular Windows Form.

You can wire-up mouse-related EventHandlers to the MDIForm: like: Click, MouseDown, Leave, MouseClick, MouseMove, Enter: none of those Events will be triggered. Note: I consider the fact you can assign EventHandlers to an MDIContainerForm in the design-time Visual Studio PropertyGrid a serious design flaw: in my opinion, those Events should never appear in the PropertyGrid for an MDIContainerForm.

However, you can assign Keyboard EventHandlers: if you set the MDIContainerForm''s KeyPreview Property to ''true: you can write EventHandlers for Events like ''KeyDown: and they will be triggered.

The whole idea (if it ever was other than a "kludge") of MDI architecture was: end-users interacted with MDI ChildForms, not with their "Parent" Form turned into an MDIContainer !

By the way, MDI is now a kind of old "fossil," and it''s butt-ugly as user-interfaces go, and it''s deprecated by Microsoft.

There are better ways of handling multiple Forms/Windows !
