winform 右下角弹出消息

Question

仿QQ消息做了一个窗体,上面有个Label,当鼠标移出窗体后渐渐消失,但我把鼠标放到Label上,它认为鼠标离开了窗体,这个怎么解决?

Answer 1

这个不是代码错误,不知道应该通过什么方法让他知道label属于winform窗体内

Answer 2

你说的是 form 的 mousemove?
可能我问题没有说清楚吧..我给form添加了 mousemove和mouselevel事件,这样做没有问题.但是我在form里面添加了一个label 我把鼠标放到label上. 就执行了mouselevel,怎么能让form知道label也属于form内呢

Answer 3

C#WinForm仿qq窗体拖到windows窗体边上时，自动隐藏C#WinForm。代码：    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void Form1_Load(object sender, EventArgs e)
        {
            
            System.Windows.Forms.Timer StopRectTimer = new System.Windows.Forms.Timer();
            StopRectTimer.Tick += new EventHandler(timer1_Tick);
            StopRectTimer.Interval = 50;
            StopRectTimer.Enabled = true;
            this.TopMost = true;
            StopRectTimer.Start();
        }        private void timer1_Tick(object sender, EventArgs e)
        {
            if (this.Bounds.Contains(Cursor.Position))
            {
                switch (this.StopAanhor)
                {
                    case AnchorStyles.Top:
                        this.Location = new Point(this.Location.X, 0);
                        break;
                    case AnchorStyles.Left:
                        this.Location = new Point(0, this.Location.Y);
                        break;
                    case AnchorStyles.Right:
                        this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - this.Width, this.Location.Y);
                        break;
                    case AnchorStyles.Bottom:
                        this.Location = new Point(this.Location.X, Screen.PrimaryScreen.Bounds.Height - this.Height);
                        break;
                }
            }
            else
            {
                switch (this.StopAanhor)
                {
                    case AnchorStyles.Top:
                        this.Location = new Point(this.Location.X, (this.Height - 8) * (-1));
                        break;
                    case AnchorStyles.Left:
                        this.Location = new Point((-1) * (this.Width - 8), this.Location.Y);
                        break;
                    case AnchorStyles.Right:
                        this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - 8, this.Location.Y);
                        break;
                    case AnchorStyles.Bottom:
                        this.Location = new Point(this.Location.X, (Screen.PrimaryScreen.Bounds.Height - 8));
                        break;
                }
            }        }        internal AnchorStyles StopAanhor = AnchorStyles.None;
        private void mStopAnhor()
        {
            if (this.Top <= 0 && this.Left <= 0)
            {
                StopAanhor = AnchorStyles.None;
            }
            else if (this.Top <= 0)
            {
                StopAanhor = AnchorStyles.Top;
            }
            else if (this.Left <= 0)
            {
                StopAanhor = AnchorStyles.Left;
            }
            else if (this.Left >= Screen.PrimaryScreen.Bounds.Width - this.Width)
            {
                StopAanhor = AnchorStyles.Right;
            }
            else if (this.Top >= Screen.PrimaryScreen.Bounds.Height - this.Height)
            {
                StopAanhor = AnchorStyles.Bottom;
            }
            else
            {
                StopAanhor = AnchorStyles.None;
            }
        }        private void hide_LocationChanged(object sender, EventArgs e)
        {
            this.mStopAnhor();
        }}在WinForm中添加Load事件给Form1_Load，添加LocationChanged事件给hide_LocationChanged。原理：主要是用Timer控件，在实时判断当前窗口的位置，如果在windows窗口的边上时，修改窗口的位置。当窗口隐藏后，实时判断鼠标的位置，如果在窗口附件，窗口显示。

Answer 4

对，就是这样的，如果form上有控件，那么放到控件上是会认为离开了form我认为你可以这样，将form作为一个Rectangle，鼠标移动的时候获取鼠标的点，然后Rectangle.Contains(point)来判断是否属于form

Answer 5

当鼠标放到Label上时, 触发mouseenter 事件,同时也触发 窗体的mouseenter  即: 你怎么判断鼠标没离开窗体的方法也绑定给Label的相应事件

Answer 6

一个提示小窗口 不会出很多控件吧,最多几个Label怕控件多 就写自定义控件.........重写mouseXXX事件.

Answer 7

 没啥麻烦的....循环+=事件就是了
类似如下
for(Control c in Form.Controls)
{
 c.事件+=xxxxxxxxxxxxxxxxxxxxxxxxxxx;
}

Answer 8

我上次也遇和你有点相似的问题，，有办法解决，当鼠标事件在窗体中的控件发生时，可以注册为窗体的事件，，
给你一个例子参考吧，，不过这个例子是按F5键，，方式都一样：http://www.cnprog.com/questions/14/WinForm程序中如何始终让窗口捕获键盘事件
