MDI Form& MDI儿童 [英] MDI Form & MDI Child

问题描述

大家好。

如果用户按下退出命令按钮，我怎么能让子MDI表格不失焦点？我已经尝试过表单show modal，但是我不能在MDI子表单中使用它

现在当用户点击MDI子表单的边缘时，表单丢失焦点和主MDI它出现

有任何建议如何避免这种情况？

Hello everybody
How can i make child MDI form to not lost focus until the user push the exit command button? i have tried form show modal, but i can't use it in MDI Child Form
Now when the user clicks at the margins of the MDI Child form, the form lost the focus and the main MDI it shows up
Any suggestion how to avoid this?

推荐答案

正式，表格 ，因为任何 Control 都有焦点，但此属性对于此类 Control 而言并不实际。实际属性是激活。 MDI的怪异之处在于：同时激活其中一个子表单的父表单。仍然，焦点的概念适用于每个表单上的一个控件，当其表单被激活时会获得焦点。我不明白为什么它会导致问题。希望这些考虑可以帮助你把它做对。至于MDI本身...



这是一个想法：谁需要MDI，永远？为什么要折磨自己并吓跑你的用户？

帮自己一个大忙：根本不要使用MDI。没有它，您可以更轻松地实现设计，质量更好。 MDI甚至被微软高度劝阻，事实上，微软将其从WPF中删除并且很难支持它。更重要的是，如果您使用MDI，您将吓跑所有用户。只是不要。请参阅：

Formally, Form, as any Control has a focus, but this property is not actual for this type of Control. The actual property is the activation. The MDI weirdness is: the parent one one of the child forms are activated at the same time. Still, the notion of focus is applicable to one of the control on each form, which gets focus when its form is activated. I don't see why it can cause a problem. Hopefully, these consideration can help you to put it right. As to the MDI itself…

Here is the idea: who needs MDI, ever? Why torturing yourself and scaring off your users?
Do yourself a great favor: do not use MDI at all. You can do much easier to implement design without it, with much better quality. MDI is highly discouraged even by Microsoft, in fact, Microsoft dropped it out of WPF and will hardly support it. More importantly, you will scare off all your users if you use MDI. Just don't.
