我想做到QQ一样自动隐藏

Question

我在FORM的MOVELEAVE和MOVEENTER中分别写了如下代码,但是好像不能做到很好,麻烦大家帮我改一下:
private void MainForm_MouseHover(object sender, EventArgs e) {
            //窗体靠左边隐藏的时候
            if (this.Left == 5 - this.Width) {
                while (this.Left < 0) {
                    this.Left++;
                }
                return;
            }            if (this.Left == Screen.PrimaryScreen.WorkingArea.Width - 5) {
                while (this.Left > Screen.PrimaryScreen.WorkingArea.Width - this.Width) {
                    this.Left--;
                }
                return;
            }            if (this.Top == 5 - this.Height) {
                while (this.Top < 0) {
                    this.Top++;
                }
                return;
            }
        }        private void MainForm_MouseLeave(object sender, EventArgs e) {
             if (this.Top <= 0) {
                if (this.Left <=0) {
                    this.Top = 0;
                    this.Height = Screen.PrimaryScreen.WorkingArea.Height;
                    this.Left = 5 - this.Width;
                    return;
                } else if (this.Left >= Screen.PrimaryScreen.WorkingArea.Width - this.Width + 5) {
                    this.Top = 0;
                    this.Height = Screen.PrimaryScreen.WorkingArea.Height;
                    this.Left = Screen.PrimaryScreen.WorkingArea.Width - 5;
                    return;
                } else {
                    this.Top = 5 - this.Height;
                    return;
                }
            }            if (this.Left <= 0) {
                this.Top = 0;
                this.Height = Screen.PrimaryScreen.WorkingArea.Height;
                this.Left = 5 - this.Width;
                return;
            }            if (this.Left >= Screen.PrimaryScreen.WorkingArea.Width - this.Width + 5) {
                this.Top = 0;
                this.Height = Screen.PrimaryScreen.WorkingArea.Height;
                this.Left = Screen.PrimaryScreen.WorkingArea.Width - 5;
                return;
            }
        }

这是我以前写的代码，你尽管用吧，比你的简单多了：private void timer1_Tick(object sender, System.EventArgs e)
{
if (this.WindowState!=System.Windows.Forms.FormWindowState.Minimized)
{
if (Cursor.Position.X>this.Left && Cursor.Position.X<this.Right && Cursor.Position.Y>this.Top && Cursor.Position.Y<this.Bottom)
{
if (this.Top<0)
{
this.Top=-5;
this.Show();
}
else if (this.Left<0)
{
this.Left=-5;
this.Show();
}
else if (this.Left+this.Width>=Screen.PrimaryScreen.WorkingArea.Width)
{
this.Left=Screen.PrimaryScreen.WorkingArea.Width-this.Width+5;
this.Show();
}
}
else
{
if(this.Top<=4)
{
this.Top=5-this.Height;
}
else if(this.Left<=4)
{
this.Left=5-this.Width;
}
else if(this.Left+this.Width>=Screen.PrimaryScreen.WorkingArea.Width-4)
{
this.Left=Screen.PrimaryScreen.WorkingArea.Width-5;
}
}
}
}

dugupiaoyun(独孤飘云)兄的思路,我来解释一下:///FORM中有个计时器,每隔多少秒轮询一下鼠标的位置,
///在FORM没有最小化的情况下的情况下，
///根据鼠标在FORM上不同的为位置选择FORM的显示和隐藏
///1、如果鼠标在FORM中而且FORM靠屏幕边缘的话，则显示
///2、如果鼠标在FORM外而且FORM靠屏幕边缘的话，则隐藏
private void timer1_Tick(object sender, System.EventArgs e)
{
         //FORM没有最小化的情况下
if (this.WindowState!=System.Windows.Forms.FormWindowState.Minimized)
{
                   if (Cursor.Position.X>this.Left && Cursor.Position.X<this.Right && Cursor.Position.Y>this.Top && Cursor.Position.Y<this.Bottom)
{//鼠标的位置在FORM之内，则显示
if (this.Top<0)
{//如果FORM靠近上边缘
this.Top=-5;
this.Show();
}
else if (this.Left<0)
{//如果FORM靠近左边缘
this.Left=-5;
this.Show();
}
else if (this.Left+this.Width>=Screen.PrimaryScreen.WorkingArea.Width)
{//如果FORM靠近右边缘 this.Left=Screen.PrimaryScreen.WorkingArea.Width-this.Width+5;
this.Show();
}
}
else
{//鼠标的位置在FORM之外，则隐藏
if(this.Top<=4)
{//如果FORM靠近上边缘
this.Top=5-this.Height;
}
else if(this.Left<=4)
{//如果FORM靠近左边缘
this.Left=5-this.Width;
}
else if(this.Left+this.Width>=Screen.PrimaryScreen.WorkingArea.Width-4)
{//如果FORM靠近右边缘 this.Left=Screen.PrimaryScreen.WorkingArea.Width-5;
}
}
}
}

不过我觉得有点小BUG，就是把窗体拉过上边缘和右边缘或左边缘的话，就会露个角而不是之前的边缘，再显示的时候就不会完全显示。我给出解决方法就是如下：
private void timer1_Tick(object sender, EventArgs e) {
            if (this.WindowState != System.Windows.Forms.FormWindowState.Minimized) {
                if (Cursor.Position.X > this.Left && Cursor.Position.X < this.Right && Cursor.Position.Y > this.Top && Cursor.Position.Y < this.Bottom) {
                    if (this.Top < 0) {
                        this.Top = -5;
                        this.Show();
                    } else if (this.Left < 0) {
                        this.Left = -5;
                        this.Show();
                    } else if (this.Left + this.Width >= Screen.PrimaryScreen.WorkingArea.Width) {
                        this.Left = Screen.PrimaryScreen.WorkingArea.Width - this.Width + 5;
                        this.Show();
                    }
                } else {
/******************变化处******************/
                    if (this.Top <= 4) {
                        this.Top = 5 - this.Height;
                        if (this.Left <= 4) {
                            this.Left =-5;
                        } else if (this.Left + this.Width >= Screen.PrimaryScreen.WorkingArea.Width - 4) {
                            this.Left = Screen.PrimaryScreen.WorkingArea.Width - this.Width + 5;
                        }
/******************变化处******************/
                    } else if (this.Left <= 4) {
                        this.Left = 5 - this.Width;
                    } else if (this.Left + this.Width >= Screen.PrimaryScreen.WorkingArea.Width - 4) {
                        this.Left = Screen.PrimaryScreen.WorkingArea.Width - 5;
                    }
                }
            }
        }
