一起移动两个表格而不改变两个表格的位置(后面或前面) [英] Moving two forms together without changing the positions (behind or front) of the two forms

问题描述

我对 C# 很陌生.最近遇到一个问题，就是想把两个不同的表格一起移动.

I am quite new to C#. Recently, I got stuck on a problem which is that I want to move two different forms together.

更详细，

一个大表单(即作为父窗口的东西)弹出一个小表单.

One big form (i.e. something as parent window) popups a small form.

我要做的是通过移动父窗口来同时移动这两个窗体.

What I want to do is to move these two forms at the same time by moving the parent window.

而且，现在我正在通过 Form 的Show()"方法创建子(小)表单.问题是，如果我点击父表单，一个小表单会在父表单后面(即更大的表单).

And, now I am creating the children (small) form by "Show()" method of Form. The problem is that if I click the parent form, a small form goes behind the parent form (i.e. bigger form).

我知道这是应该发生的.但是，我想通过移动较大的表格同时保持小表格在前面来移动这两个表格.

I know this is what should happen. However, I want to move these two forms by moving the bigger form while keeping the small form is front.

我也考虑过使用ShowDialog()".但是，这阻止了我移动更大的父母.我无法触摸父窗口.

I also considered using "ShowDialog()". But, this prevent me from moving the bigger parent. I cannot event touch the parent window.

推荐答案

将子窗体的 Owner 属性设置为父窗体:

Set the child form's Owner property to the parent form:

this.childForm = new ChildFormClass();
child.Owner = this;
viewForm.ShowDialog();
//Can also be called like this instead of setting Owner property:
//viewForm.ShowDialog(this);

参考:http://msdn.microsoft.com/en-us/library/system.windows.forms.form.owner.aspx

这样，子窗体将永远不会显示在父窗体后面.

This way, the child form will never be shown behind the parent.

要将两个表单一起移动，只需处理父表单的 Move 事件:

To move both forms together, simply handle the parent's form Move event:

private void Form1_Move(object sender, EventArgs e)
{
    Point p = this.PointToScreen(new Point(this.ClientRectangle.X, this.ClientRectangle.Y));
    this.childForm.Location = p; //childForm needs to be a class member
}
