I know my question sounds basic, but i searched all over the place and found nothing.. this is my code :
我知道我的问题听起来很基本,但我搜遍了整个地方,什么都没找到......这是我的代码:
public MainWindow()
{
InitializeComponent();
Map newMap = new Map();
newMap.setMapStrategy(new SmallMapStrategy());
newMap.createMap();
System.Windows.Forms.PictureBox pictureBox1 = new System.Windows.Forms.PictureBox();
pictureBox1.Paint += new System.Windows.Forms.PaintEventHandler(newMap.grid[3].afficher);
}
this is the afficher function :
这是一个功能:
public override void afficher(object sender, PaintEventArgs e)
{
e.Graphics.DrawImage(squareImage, pos_x, pos_y, 50, 50);
}
squareImage is an attribute corresponding to a Drawing.Image. pos_x and pos_y are custom int32 attributes.
squareImage是与Drawing.Image对应的属性。 pos_x和pos_y是自定义int32属性。
What i'd like is to SEE the image while running my application...
我想要的是在运行我的应用程序时看到图像...

Since the PictureBox that you are using is a Winforms Control you will need to add a WindowsFormsHost Control to your Wpf Form and add the PictureBox to that. Any time you dynamically create a control you need to add it to the Form or Container object otherwise it will not be shown.
由于您使用的PictureBox是Winforms控件,因此您需要将WindowsFormsHost控件添加到Wpf窗体并将PictureBox添加到其中。无论何时动态创建控件,都需要将其添加到Form或Container对象中,否则将无法显示。
i.e. something like this.
即这样的事情。
MainWindow.xaml

e.Graphics.DrawImage(bmp,ulPoint);
}
}
