逐步解說：在 Windows Form 中裝載立體 WPF 複合控制項

  • 發行項

本逐步解說會示範如何建立 WPF 複合控制項，並使用 ElementHost 控制項將它裝載 (Host) 於 Windows Forms 控制項和表單中。

在本逐步解說中，您會實作包含兩個子控制項的 WPF UserControl。 UserControl 會顯示立體 (3-D) 圓錐體。 由於使用 WPF 呈現立體物件要比使用 Windows Forms 來呈現簡單的多， 因此才會有在 Windows Forms 中裝載 WPF UserControl 類別來建立立體圖形的這種做法。

逐步解說將說明的工作包括：

如需這個逐步解說中所說明之工作的完整程式碼清單，請參閱在 Windows Form 中裝載立體 WPF 複合控制項範例 (英文)。

必要條件

您需要下列元件才能完成此逐步解說：

  • Visual Studio 2008。

建立使用者控制項

若要建立使用者控制項

  1. 建立 WPF 使用者控制項程式庫專案，並命名為 HostingWpfUserControlInWf。

  2. 在 WPF 設計工具中開啟 UserControl1.xaml。

  3. 將產生的程式碼取代成下列程式碼：

    這個程式碼會定義含有兩個子控制項的 System.Windows.Controls.UserControl。 第一個子控制項是 System.Windows.Controls.Label 控制項，第二個則是會顯示立體圓錐體的 Viewport3D 控制項。

    <UserControl x:Class="HostingWpfUserControlInWf.UserControl1"
    xmlns="https://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="https://schemas.microsoft.com/winfx/2006/xaml"
    >

    <Grid>

      <!-- Place a Label control at the top of the view. -->
      <Label 
                HorizontalAlignment="Center" 
                TextBlock.TextAlignment="Center" 
                FontSize="20" 
                Foreground="Red" 
                Content="Model: Cone"/>

      <!-- Viewport3D is the rendering surface. -->
      <Viewport3D Name="myViewport" >

        <!-- Add a camera. -->
        <Viewport3D.Camera>
          <PerspectiveCamera 
                        FarPlaneDistance="20" 
                        LookDirection="0,0,1" 
                        UpDirection="0,1,0" 
                        NearPlaneDistance="1" 
                        Position="0,0,-3" 
                        FieldOfView="45" />
        </Viewport3D.Camera>

        <!-- Add models. -->
        <Viewport3D.Children>

          <ModelVisual3D>
            <ModelVisual3D.Content>

              <Model3DGroup >
                <Model3DGroup.Children>

                  <!-- Lights, MeshGeometry3D and DiffuseMaterial objects are added to the ModelVisual3D. -->
                  <DirectionalLight Color="#FFFFFFFF" Direction="3,-4,5" />

建立 Windows Form 主專案

若要建立主專案

  1. 將名稱為 WpfUserControlHost 的 Windows 應用程式專案加入至方案。 如需詳細資訊，請參閱 HOW TO：建立新的 WPF 應用程式專案。

  2. 在 [方案總管] 中，加入名為 WindowsFormsIntegration.dll 的 WindowsFormsIntegration 組件之參考。

  3. 加入下列 WPF 組件的參考：

    • PresentationCore

    • PresentationFramework

    • WindowsBase

  4. 加入 HostingWpfUserControlInWf 專案的參考。

  5. 在 [方案總管] 中，設定要做為啟始專案的 WpfUserControlHost 專案。

裝載 Windows Presentation Foundation 使用者控制項

若要裝載使用者控制項

  1. 在 [Windows Form 設計工具] 中開啟 Form1。

  2. 在 [屬性] 視窗中按一下 [事件]，然後按兩下 Load 事件以建立事件處理常式。

    [程式碼編輯器] 會開啟在新產生 Form1_Load 事件處理常式的地方。

  3. 將 Form1.cs 中的程式碼取代成下列程式碼。

    Form1_Load 事件處理常式會建立 UserControl1 執行個體，並將它加入ElementHost 控制項的子控制項集合。 而 ElementHost 控制項則會再加入至表單的子控制項集合。

    Imports System
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Data
Imports System.Drawing
Imports System.Text
Imports System.Windows.Forms

Imports System.Windows.Forms.Integration

Public Class Form1
    Inherits Form

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ' Create the ElementHost control for hosting the
        ' WPF UserControl.
        Dim host As New ElementHost()
        host.Dock = DockStyle.Fill

        ' Create the WPF UserControl.
        Dim uc As New HostingWpfUserControlInWf.UserControl1()

        ' Assign the WPF UserControl to the ElementHost control's
        ' Child property.
        host.Child = uc

        ' Add the ElementHost control to the form's
        ' collection of child controls.
        Me.Controls.Add(host)
    End Sub

End Class

    using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

using System.Windows.Forms.Integration;

namespace WpfUserControlHost
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            // Create the ElementHost control for hosting the
            // WPF UserControl.
            ElementHost host = new ElementHost();
            host.Dock = DockStyle.Fill;

            // Create the WPF UserControl.
            HostingWpfUserControlInWf.UserControl1 uc =
                new HostingWpfUserControlInWf.UserControl1();

            // Assign the WPF UserControl to the ElementHost control's
            // Child property.
            host.Child = uc;

            // Add the ElementHost control to the form's
            // collection of child controls.
            this.Controls.Add(host);
        }
    }
}

  4. 按 F5 建置並執行應用程式。
