Question

通过查看超图的示例代码，发现可以在子程序中实现主窗体的mapcontrol_mousedown事件，但是自己尝试一直不成功，想知道是如何实

/// <summary>
		/// MapControl MouseDown事件。
		/// MouseDown event of MapControl
		/// </summary>
		private void m_mapControl_MouseDown(object sender, MouseEventArgs e)//在子程序里如何编写实现
		{
			try
			{
				if (e.Button == MouseButtons.Left)
				{
					Point point = new Point(e.X, e.Y);
					Point2D mapPoint = m_mapControl.Map.PixelToMap(point);
					if (m_mapControl.Map.Bounds.Contains(mapPoint))
					{
						if ((m_mapControl.Action == SuperMap.UI.Action.Select
								|| m_mapControl.Action == SuperMap.UI.Action.Select2)
								&& m_selectMode == SelectMode.SelectPoint)
						{
							AddPoint(mapPoint);
						}
					}
				}
			}
			catch (Exception ex)
			{
				Trace.WriteLine(ex.Message);
			}
		}

现在子程序中编写主窗体的mapcontrol_mousedown事件的。

你好,把mapcontrol传值到子窗体,然后在子窗体调用就行了
