使用按钮向右和向左移动面板单击C#

Question

我正在使用WinForms.在我的表格中,我有一个带按钮的面板可以移动面板.例如,向上和向下按钮可向上或向下移动面板.我在使用相应的按钮左右移动面板时遇到困难.我做错了什么？

    private void Up_btn_Click(object sender, EventArgs e)
    {
        if (panel1.Location.Y > -2000) 
        {
            panel1.Location = new Point(panel1.Location.X, panel1.Location.Y - 80);        
        }
    }

    private void Down_btn_Click(object sender, EventArgs e)
    {
        if (panel1.Location.Y < 720) 
        {
            panel1.Location = new Point(panel1.Location.X, panel1.Location.Y + 80);
        }
    }

    private void Left_btn_Click(object sender, EventArgs e)
    {
        if (panel1.Location.X < 720) 
        {
            panel1.Location = new Point(panel1.Location.Y , panel1.Location.X + +55);             
        }
    }

    private void Right_btn_Click(object sender, EventArgs e)
    {
        if (panel1.Location.X < 720) 
        {
            panel1.Location = new Point(panel1.Location.Y, panel1.Location.X -55);
        }
    }

Answer 1

在最后两种方法中,x和y的顺序不正确.

要向左移动,你应该减少X:

panel1.Location = new Point(panel1.Location.X - 55, panel1.Location.Y);

要向右移动,你应该增加X:

panel1.Location = new Point(panel1.Location.X + 55,  panel1.Location.Y , ); 

我也想,如果你使用了与标准>-y和向下<y,也许你需要左右这样的逻辑>-x和<x.

Answer 2

(是的,我知道由于协调问题,我们确实破坏了我们的数学测试!)

问题

Point()总是(x,y)坐标.在你的代码中:

private void Left_btn_Click(object sender, EventArgs e)
{
    if (panel1.Location.X < 720) 
    {
        panel1.Location = new Point(panel1.Location.Y , panel1.Location.X + +55);             
    }
}

private void Right_btn_Click(object sender, EventArgs e)
{
    if (panel1.Location.X < 720) 
    {
        panel1.Location = new Point(panel1.Location.Y, panel1.Location.X -55);
    }
}

您将X坐标与Y值相对应,反之亦然.

旁注:+你的左键点击事件也有一个双..

步骤1

首先,反过来:

private void Left_btn_Click(object sender, EventArgs e)
{
    if (panel1.Location.X < 720) 
    {
        panel1.Location = new Point(panel1.Location.X + 55 , panel1.Location.Y);             
    }
}

private void Right_btn_Click(object sender, EventArgs e)
{
    if (panel1.Location.X < 720) 
    {
        panel1.Location = new Point(panel1.Location.X - 55, panel1.Location.Y);
    }
}

第2步

其次,看看左右是否是你想要的.请注意,向左移动意味着我们减少X并向右移动我们增加X.

不应该这样做吗？

private void Left_btn_Click(object sender, EventArgs e) //The name is Left
{
    if (panel1.Location.X < 720) 
    {
        panel1.Location = new Point(panel1.Location.X - 55 , panel1.Location.Y);             
    }
}

private void Right_btn_Click(object sender, EventArgs e) //The name is Right
{
    if (panel1.Location.X < 720) 
    {
        panel1.Location = new Point(panel1.Location.X + 55, panel1.Location.Y);
    }
}
