如何CenterParent非模态窗体

本文介绍了如何CenterParent非模态窗体的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个从父窗体开辟了一个非模态子窗体。我需要给孩子表格中心其父形式。我已经设置子窗体的属性 CenterParent ，并试图这样的：

I have a non-modal child form which opens up from a parent form. I need to center the child form to its parent form. I have set property of child form to CenterParent and tried this:

Form2 f = new Form2(); f.Show(this);

但无济于事。这适用于模态的形式，但不能因此与非模态形式。任何简单的解决方案，还是需要我去通过所有的数学计算来解决它的位置居中？

but to no avail. This works with modal form, but not so with non-modal forms. Any simple solution, or need I go through all that mathematical calculation to fix its position to center?

推荐答案

恐怕 StartPosition.CenterParent 仅用于模态对话框好（ .ShowDialog ）。结果你必须手动设置的位置这样：

I'm afraid StartPosition.CenterParent is only good for modal dialogs (.ShowDialog). You'll have to set the location manually as such:

Form f2 = new Form(); f2.StartPosition = FormStartPosition.Manual; f2.Location = new Point(this.Location.X + (this.Width - f2.Width) / 2, this.Location.Y + (this.Height - f2.Height) / 2); f2.Show(this);
