分享有关MDI窗体大小的问题!
MDI窗体问题,主窗体FormStyle := fsMDIForm,其他子窗体均为fsMDIChild
问题来了,若打开的子窗体中有一个是最大化的,接着打开其他窗体也就跟着最大化了,
我想让各自的窗体打开时还是其在设计期间的大小,请问有办法解决吗?

那可能需要去拦截一些消息，重载Form，做这方面处理。有空试试看。

--在窗口显示的时候，设置窗口大小即可。可通过配置或者直接在程序里设置。
当MDI子窗体有一个最大化时,其他打开的窗体都是跟着最大化的,当有一个窗体没有最大化时,其他已经最大化的窗体也会跟着变成没有最大化,这样一个窗体的状态就会破坏其他窗体的状态

我的窗体都是ws_Mormal来显示的,
问题是,当我需要最大化的时候若改成align是会发生如下问题:窗体的关闭,还原,最小化按钮不见了

你总结上面所有的回答，你的问题肯定能解决，好好想一下
你的要求：有些需要最大化，有些需要原始尺寸
你的问题：最大化的会影响其它原始尺寸窗体的状态
解决：所有窗体都按ws_normal来显示，就是原始尺寸
需要最大化的窗体程序改align或者设置尺寸，而不使用真正的最大化命令
你是不是想要人贴出来代码？

没错,是要拦截消息,就是不知道具体的做法

上面不是说了么：把需要最大化的窗体align设为Client.让它的客户区填满client区域

我想要的效果是,当子窗体最大化时,标题栏不要最大化跟主窗体合并,也就是让子窗体最大化不填满区域的效果!

有没有人知道正航软件的,就是要那种效果啦

如果所有窗体都需要设计时的大小的话，你就拦掉上面的最大化消息（或其它你想拦掉的消息）就行了啊。
如果你有时候想手动填满区域，你就程序设计align啊，别在设计时的属性里设置

align设为Client,有个问题,每次打开都变成填满区域,我要的是能保持在设计期间时的大小

SC_HOTKEY
Activates the window associated with the application-specified hot key. The lParam parameter identifies the window to activate.
SC_HSCROLL

SC_KEYMENU
Retrieves the window menu as a result of a keystroke. For more information, see the Remarks section.
SC_MAXIMIZE
Maximizes the window.
SC_MINIMIZE
Minimizes the window.
SC_MONITORPOWER
Sets the state of the display. This command supports devices that have power-saving features, such as a battery-powered personal computer.

The high-order word specifies the vertical position of the cursor, in screen coordinates, if a window menu command is chosen with the mouse. This parameter is –1 if the command is chosen using a system accelerator, or zero if using a mnemonic.
Return Value
An application should return zero if it processes this message.
