如何去除MDIchild形式控制箱 [英] How to remove control box from MDIchild form

问题描述

当我加载在的MdiParent 子窗体也出现在控制箱。我想删除的控制箱及子窗体的边界。
我也正在写代码

 私人无效Form_mainMenu_Load（对象发件人，EventArgs五）
 { 
 this.WindowState = FormWindowState.Maximized; 
 this.ControlBox = FALSE; 
 this.FormBorderStyle = FormBorderStyle.None; 
} 
  

解决方案

如果你真的想定制mdiChild窗口的标题栏的外观，看来你需要通过处理 WM_NCPAINT 信息处理子窗口的非客户区的画。
你也需要处理，比如 WM_SETCURSOR ， WM_MOUSEMOVE ， WM_NCLBUTTONDOWN ...

您也可以使用面板代替的MdiParent一种解决方法。

1. 创建父窗体，并没有设置的IsMdiContainer 。


2. 添加面板到父窗体并命名为ContainerPanel，并设置其码头属性来填补。


3. 创建您的孩子的形式，并与无边框添加到面板风格，没有控制中，填写码头风格和非顶层

下面是示例代码：

 变种F =新ChildForm（）; 
 f.TopLevel = FALSE; 
 f.ControlBox = FALSE; 
 f.Dock = DockStyle.Fill; 
 f.BorderStyle = System.Windows.Forms.BorderStyle.None; 
 
 / *我认为这个代码是在你的ParentForm等这个指向包含ContainerPanel * / 
 this.ContainerPanel.Controls.Add ParentForm（F）; 
 f.Show（）; 
  

使用这样的方法，你可以控制你的手的各个方面取得的MDI窗口。例如，你可以使用菜单显示打开的窗口列表和工具条关闭窗口。

When I'm loading a child form in MDIparent the control box also appears. I want to remove the control box and the border of child form. Also I'm writing code as

private void Form_mainMenu_Load(object sender, EventArgs e)
{
     this.WindowState = FormWindowState.Maximized;
     this.ControlBox = false;
     this.FormBorderStyle = FormBorderStyle.None;
}

解决方案

If you really want to customize the appearance of title bar of mdiChild Window, it seems you need handle painting of non-client areas of child window by handling WM_NCPAINT message. Also you need to handle messages like WM_SETCURSOR, WM_MOUSEMOVE, WM_NCLBUTTONDOWN, ... .

As a workaround you can use a panel instead of mdiParent.

1. Create parent form and don't set IsMdiContainer.
2. Add a panel to your parent form and name it "ContainerPanel" and set its Dock property to fill.
3. Create your child form and add it to panel with none border style, no control box, fill dock style and non top level.

Here is sample code:

var f = new ChildForm();
f.TopLevel = false;
f.ControlBox = false;
f.Dock = DockStyle.Fill;
f.BorderStyle = System.Windows.Forms.BorderStyle.None;

/*I assume this code is in your ParentForm and so 'this' points to ParentForm that contains ContainerPanel*/
this.ContainerPanel.Controls.Add(f);
f.Show();

Using such method you can control every aspect of your hand made mdi window. For example you can use a Menu to show list of open windows and a toolstrip to close windows.
