我实现的是一个异形窗口(圆形),异形窗口的移动是在其鼠标事件中完成的,
拖动的时候如果完全在父窗口的PictureBox控件内就没有拖尾,如果移动至PicuteBox与其它控件的
交界处就有严重的拖尾,在其它控件的交接处,以及标题栏、工具栏与PictureBox等空间的交界处
拖尾现象也很严重,请问这是怎么回事?应该怎么解决?谢谢
主要代码如下:
public void ShapedForm_MouseDown(object sender, MouseEventArgs e)
{
bFormDragging = true;
oPointClicked = new Point(e.X,e.Y);
} public void ShapedForm_MouseUp(object sender, MouseEventArgs e)
{
bFormDragging = false;
} public void ShapedForm_MouseMove(object sender, MouseEventArgs e)
{
if (bFormDragging)
{
oMoveToPoint = this.PointToScreen(new Point(e.X, e.Y));
oMoveToPoint.Offset(oPointClicked.X * -1,
(oPointClicked.Y + SystemInformation.CaptionHeight +
SystemInformation.BorderSize.Height) * -1);
this.Location = oMoveToPoint;
}
}

试了下 楼主的代码 MouseMove 的时候 设置bFormDragging = false; 根本就拖不动 要改为true;也没出现楼主说的拖尾 很严重的现象.... 是不是楼主 自己的那个窗体 设计的太复杂了.....放的控件比较多.... 或者机器的显卡问题
