DevExpress12、DocumentManager

DocumentManager控件

      你用过Photoshop吗？里面每打开一个照片，就有一个小窗体承载这个照片，你可以在这些小窗体间切换，最小化、最大化、排列窗体，

这些操作都在Photoshop的大框架（MDI主窗体）里，而这些小窗体就是MDI子窗体。

      MDI是Multiple Document Interface的缩写，就是多文档界面的意思。它是和单文档SDI相对的。

MDI和SDI在界面上的主要区别如下：MDI允许用户同时打开多个文档，而SDI只能打开一个文档。

      MDI子窗体可以通过DocumentManger控件,以 nativemdiview 对象或 tabbedview 对象的形式展现出来；

通过其 ViewCollection属性 添加View视图（子窗体），可以添加TabbedView、WindowsUIView、WidgetView、NativeMdiView四种视图；

通过Run Designer中Main下的Document给视图添加Document文档（显示的面板）；

NativeMdiView视图

实现效果如图：

通过代码实现如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
using DevExpress.XtraEditors;
using DevExpress.XtraBars.Docking2010;
using DevExpress.XtraBars.Docking2010.Views.NativeMdi;

namespace DXApplication_1
{
    public partial class DocumentMangerForm : DevExpress.XtraEditors.XtraForm
    {
        public DocumentMangerForm()
        {
            InitializeComponent();
        }

        private void DocumentMangerForm_Load(object sender, EventArgs e)
        {
            Encapsulation_CreateDocumentManager();
            for (int i = 0; i < 3; i++) {
                Encapsulation_AddChild(); 
            }
        }

        void Encapsulation_CreateDocumentManager() {
            DocumentManager documentManager = new DocumentManager();
            documentManager.MdiParent = this;
            // type one
            documentManager.View = new NativeMdiView();
        }

        int childCount = 0;
        void Encapsulation_AddChild() {
            Form childForm = new Form();
            childForm.Text = "Child Form " + (++childCount);

            SimpleButton btn = new SimpleButton();
            btn.Text = "Button " + childCount;
            btn.Parent = childForm;

            // 
            childForm.MdiParent = this;
            childForm.Show();
        }
    }
}

TabbedView视图

实现效果如图：

代码实现如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
using DevExpress.XtraEditors;
using DevExpress.XtraBars.Docking2010;
using DevExpress.XtraBars.Docking2010.Views.Tabbed;

namespace DXApplication_1
{
    public partial class DocumentMangerForm2 : DevExpress.XtraEditors.XtraForm
    {
        public DocumentMangerForm2()
        {
            InitializeComponent();
        }

        private void DocumentMangerForm2_Load(object sender, EventArgs e)
        {
            Encapsulation_CreateDocumentManager();
            for (int i = 0; i < 3; i++)
            {
                Encapsulation_AddChild();
            }
        }

        void Encapsulation_CreateDocumentManager()
        {
            DocumentManager documentManager = new DocumentManager();
            documentManager.MdiParent = this;
            // another type 
            documentManager.View = new TabbedView();
        }

        int childCount = 0;
        void Encapsulation_AddChild()
        {
            Form childForm = new Form();
            childForm.Text = "Child Form " + (++childCount);

            SimpleButton btn = new SimpleButton();
            btn.Text = "Button " + childCount;
            btn.Parent = childForm;

            // 
            childForm.MdiParent = this;
            childForm.Show();
        }
    }
}
