如何在ZedGraph中订阅MouseDown事件 [英] How to subscribe for MouseDown event in a ZedGraph

问题描述

我需要使用鼠标按下事件拖动它来移动曲线。如果在代码中动态生成曲线，我如何订阅此事件（我的意思是我不将其作为控件添加到设计中）。



I写了这个函数

Hi,
I need to move a curve by drag it using mouse down event. How do i subscribe for this event if the curve is generated dynamically in the code (I mean I don't add it in the design as a control).

I wrote this function

Private Sub zgc_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseDown
        Dim p As PointF
        p = e.Location
        Dim x, y As Double
        If e.Button = Windows.Forms.MouseButtons.Left Then
            '..........
        End If

    End Sub

但是当我点击表格中的任何位置时它都有效，除了图表：（



先谢谢你，

Arwa

but it works when I click in any position in the form EXCEPT the graph :"(

Thank you in advanced,
Arwa

推荐答案

您好Arwa，您可以将处理程序例程下划线到 MouseDownEvent 。



这是我使用的代码片段：

Hi Arwa, you can subscibe your handler routine to the MouseDownEvent.

This is a snippet of the code I used:

public Form1()
{
     InitializeComponent();
     ...

     ZedGraphControl1.MouseDownEvent += ZedGraphControl1_MouseDownEvent;
}

private bool GraphControl_MouseDownEvent(ZedGraphControl sender, MouseEventArgs e)
{
     Console.WriteLine("Mouse Down event");

     // Your code ...

     return true;
}
