移动控件的问题
程序代码：private bool isMouseDown = false;
private Point mouseOffset; //记录鼠标指针的坐标
int button1_point = 10000000;
private void button1_MouseDown(object sender, MouseEventArgs e)
{
if (button1.Left != button1_point && button1_point != 10000000)
{
isMouseDown = false;
button1_point = 10000000;
return;
}
if (e.Button == MouseButtons.Left)
{
button1_point = button1.Left;
mouseOffset.X = e.X;
mouseOffset.Y = e.Y;
isMouseDown = true;
}
}
private void button1_MouseMove(object sender, MouseEventArgs e)
{
if (isMouseDown)
{
button1.BringToFront();
int left = button1.Left + e.X - mouseOffset.X;
int top = button1.Top + e.Y - mouseOffset.Y;
button1.Location = new Point(left, top);
}
}
用这种方法 移动控件 如果鼠标移动太快，会把 控件甩丢 有什么好的解决方案，控制 移动的控件必须跟紧鼠标 或者防止甩下移动的控件，就把对应移动的控件 返回到 原来的 Location里面
