从其他表单删除动态添加的按钮 [英] Delete a dynamically added button from another form

问题描述

当我按下一个按钮时，我会在form1上动态添加按钮.当我按下form2上的按钮时，必须删除form1上的按钮.我该怎么做?

I dynamically add buttons on form1 when I press a button. When I press a button on form2, the buttons on form1 must be deleted. How can I do this?

推荐答案

我可以直接或通过form2的自定义事件来使form1订阅form2的按钮单击事件.然后在form1消息处理程序中删除所需的按钮.

我认为这两种形式都是无模式的.

I would get form1 the subscribe to the button click event of form2, either direct or via a custom event of form2. Then in form1 message handler remove the buttons you want.

I presume both forms are modeless

您可以在Form1中订阅Form2按钮事件，然后对其做出反应.由于表单中的大多数控件默认情况下都是私有的，因此您可能必须将按钮设为公开.

或者，您可以在Form2中发布一个供Form 1订阅的自定义(公共)事件，然后在Form2中触发具有适当操作的事件.

You can subscribe to the Form2 button event in Form1, and just react to it. Since most controls in a form are private by default, you''ll probably have to make the button public.

Alternatively, you can post a custom (public) event in Form2 that Form 1 can subscribe to, and fire that event with the appropriate action has happened in Form2.
