UC知道C#移动窗体的问题
来源：百度知道 编辑：UC知道 时间：2024/09/20 07:06:24
我用了两种方法一种正常，一种不正常
第一种不正常，能否告诉我为何？
private void Main_MouseDown(object sender, MouseEventArgs e)
{
m__RectOrg.X = e.X;
m__RectOrg.Y = e.Y;
}
private void Main_MouseMove(object sender, MouseEventArgs e)
{
if (MouseButtons.Left == e.Button)
{
Left -= m__RectOrg.X - e.X;
Top += m__RectOrg.Y - e.Y;
m__RectOrg.X = e.X;
m__RectOrg.Y = e.Y;
}
}
想法是每次移动鼠标加上与上一次的差值，但效果不一样，大家试一下回答我

int x0, y0;
private void Form1_MouseDown(object sender, MouseEventArgs e)
{
x0 = e.X;
y0 = e.Y;
this.Capture = true;
}
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
if (this.Capture)
{
int x1 = e.X;
int y1 = e.Y;
this.Location = new Point(this.Left + (x1 - x0), this.Top + (y1 - y0));
}
}
private void Form1_MouseUp(object sender, MouseEventArgs e)
{
this.Capture = false;
}
需要用2个全局变量来记录上一次的x,y
