思路是这样的.得有三个变量.
记录x坐标: int xPos;
记录y坐标: int yPos;
记录是否按下鼠标: bool MoveFlag;
//在picturebox的鼠标按下事件里,记录三个变量.
private void picBox_MouseDown(object sender, MouseEventArgs e)
{
MoveFlag = true;//已经按下.
xPos = e.X;//当前x坐标.
yPos = e.Y;//当前y坐标.
}
//在picturebox的鼠标按下事件里.
private void picBox_MouseUp(object sender, MouseEventArgs e)
{
MoveFlag = false;
}
//在picturebox鼠标移动
private void picBox_MouseMove(object sender, MouseEventArgs e)
{
if (MoveFlag)
{
picBox.Left += Convert.ToInt16(e.X - xPos);//设置x坐标.
picBox.Top += Convert.ToInt16(e.Y - yPos);//设置y坐标.
}
}
这样就可以实现控件在容器里的移动
