为什么我的MDI子窗体没有显示阴影？ [英] Why aren't my MDI child forms showing a shadow?

问题描述

在我的应用程序中，当我将窗体作为主MDI父窗体的子窗体创建时，该子窗体停止在窗体后面显示Windows 7默认阴影效果。如何获得子表格阴影显示？

In my application when I make a form as a child form of my main MDI parent form, the child form stops showing Windows 7 default shadow effect behind forms. How do I get child forms shadow to show?

Form obj = Application.OpenForms["My_form"];
if (obj != null)
{
    obj.Focus();
}
else
{
    My_form c = new My_form();
    c.MdiParent = this;
    c.Show();
}

推荐答案

我终于得到了答案，如果我将子窗体做成

I got the answer finally , if i make a form as child form like

c.MdiParent =this;

如果您希望将表单显示为默认窗口，例如表格
不会成为表格的MDI父项！

It makes the appearance of the form as flat , If you like to show the form as default windows like forms dont make the form's mdi parent !
