Demonstra Passo a passo: Hospedando um controle composto do WPF 3D no Windows Forms

Artigo
08/04/2011

This walkthrough demonstrates how you can create a WPF composite control and host it in Windows Forms controls and forms by using the ElementHost control.

Esta explicação passo a passo, você irá implementar um WPF UserControl que contém dois controles filho. O UserControl exibe uma tridimensional (3D) cone. Processamento de objetos 3D é muito mais fácil com o WPF que com Windows Forms. Portanto, faz sentido para o host de um WPF UserControl classe para criar elementos gráficos 3D em Windows Forms.

Tasks illustrated in this walkthrough include:

Criando o WPF UserControl.
Creating the Windows Forms host project.
Hospedando o WPF UserControl.

Para obter uma listagem de código completo das tarefas ilustradas nesta explicação, consulte que hospeda um controle composto do WPF 3D Windows Forms de exemplo.

Pré-requisitos

You need the following components to complete this walkthrough:

Visual Studio 2008.

Creating the UserControl

To create the UserControl

Create a WPF User Control Library project named HostingWpfUserControlInWf.
Open UserControl1.xaml in the WPF Designer.

Replace the generated code with the following code.

This code defines a System.Windows.Controls.UserControl that contains two child controls. O primeiro controle filho é um System.Windows.Controls.Label controle; o segundo é um Viewport3D controle que exibe um cone 3D.

<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" />

                  <!-- Define a red cone. -->
                  <GeometryModel3D>

Creating the Windows Forms Host Project

To create the host project

Add a Windows application project named WpfUserControlHost to the solution. For more information, see Como: Criar um novo projeto de aplicativo WPF.
In Solution Explorer, add a reference to the WindowsFormsIntegration assembly, which is named WindowsFormsIntegration.dll.
Add references to the following WPF assemblies:
- PresentationCore
- PresentationFramework
- WindowsBase
Add a reference to the HostingWpfUserControlInWf project.
In Solution Explorer, set the WpfUserControlHost project to be the startup project.

Hosting the Windows Presentation Foundation UserControl

To host the UserControl

In the Windows Forms Designer, open Form1.
In the Properties window, click Events, and then double-click the Load event to create an event handler.

The Code Editor opens to the newly generated Form1_Load event handler.

Replace the code in Form1.cs with the following code.

O Form1_Load manipulador de eventos cria uma instância de UserControl1 e adiciona-para o ElementHost de coleção controle de todos os controles filho. The ElementHost control is added to the form's collection of child controls.

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);
        }
    }
}
