Halcon可以通过HDevEngine创建自定义控件,步骤如下:
1. 创建一个继承自System.Windows.Forms.Control的类,例如:
```
public class HalconWindow : System.Windows.Forms.Control
{
private HWindowControl _hWindowControl;
public HalconWindow()
{
_hWindowControl = new HWindowControl();
_hWindowControl.Dock = System.Windows.Forms.DockStyle.Fill;
this.Controls.Add(_hWindowControl);
}
public HWindow HWindow
{
get { return _hWindowControl.HalconWindow; }
}
}
```
2. 在Halcon程序中创建HDevEngine对象,并将自定义控件加载到HDevEngine中,例如:
```
HDevEngine hdev = new HDevEngine();
hdev.AddCommand("open_window", new OpenWindowCommand());
hdev.ExecuteString("open_window(\"halcon_window\", 0, 0, 640, 480, \"black\", \"\", \"\", out_win);");
```
其中,OpenWindowCommand类可以定义如下:
```
public class OpenWindowCommand : HDevCommand
{
public override void ExecuteImpl(HDevEngine hdev)
{
string name = hdev.GetInputString("Name");
int row1 = hdev.GetInputInt("Row1");
int col1 = hdev.GetInputInt("Column1");
int row2 = hdev.GetInputInt("Row2");
int col2 = hdev.GetInputInt("Column2");
string background = hdev.GetInputString("Background");
string title = hdev.GetInputString("Title");
string options = hdev.GetInputString("Options");
HalconWindow window = new HalconWindow();
window.Name = name;
window.Location = new Point(col1, row1);
window.Size = new Size(col2 - col1, row2 - row1);
window.HWindow.SetWindowParam("background_color", background);
window.HWindow.SetWindowParam("title", title);
window.HWindow.SetWindowParam("graphics_stack_size", 1024 * 1024);
window.HWindow.SetWindowParam("graphics_stack_trace", "true");
hdev.SetOutputObject("out_win", window);
}
}
```
3. 在自定义控件的代码中,可以通过HalconWindow.HWindow属性获取到Halcon窗口对象,例如:
```
private void button1_Click(object sender, EventArgs e)
{
HalconWindow halconWindow = new HalconWindow();
HWindow hWindow = halconWindow.HWindow;
hWindow.SetColor("red");
hWindow.DispLine(100, 100, 200, 200);
}
```
这样就可以在自定义控件中显示Halcon图像,并且可以使用Halcon的图像处理函数进行操作。
