【WPF】实现窗体贴边隐藏

1.新建WPF项目Test，主窗体MainWindow.xaml，在后台MainWindow.xaml.cs填写下面的代码。主窗体调用Hide类，实现隐藏功能。

//有些引用可能是不需要的，视情况而定
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Windows.Threading;

using System.ServiceModel;
using System.Drawing; //添加引用
using System.Windows.Forms;//添加引用
using System.Diagnostics;
using System.Runtime.InteropServices;
using MouseEventArgs = System.Windows.Input.MouseEventArgs;

using EF;
using BLL;
using System.Data;

namespace Test
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
      
        public MainWindow()
        {
            InitializeComponent();

          //实例化隐藏 Hide类，进行时间timer设置
            Hide hide1 = new Hide(this);
            hide1.TimerSet();


        }
        #region 窗体贴边隐藏功能
        public void hide()
        {
       		 //实例化隐藏 Hide类
            Hide hide1 = new Hide(this);
            object o = new object();
            EventArgs e = new EventArgs();
            hide1.timerDealy(o, e);
        }
        #endregion
   }
}

2.新建Hide类。主要实现隐藏功能

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using System.Drawing; //添加引用
using System.Windows.Forms;//添加引用
using System.ServiceModel;
using MouseEventArgs = System.Windows.Input.MouseEventArgs;
using System.Windows;

namespace Test
{

    public class Hide
    {
        Window f;//定义使用该方法的窗体
        //构造函数，传入将要匹配的窗体      
        public Hide(Window f)
        {
            this.f = f;
        }
		//设定时间
        public void TimerSet()
        {
            Timer timer = new Timer();//添加timer计时器，隐藏功能
            #region 计时器设置，隐藏功能
            timer.Interval = 100;
            timer.Tick += timerDealy;
            timer.Start();
            #endregion
        }
        #region 窗体贴边隐藏功能
        public void timerDealy(object o, EventArgs e)
        {

            if (f.Top > 3 && f.Left > 3)
            {
                return;
            }

            //获取鼠标在屏幕上的位置
            double mouse_x = Form.MousePosition.X;   //需要添加引用System.Drawing
            double mouse_y = Form.MousePosition.Y;
            //设置窗体顶部隐藏满足的条件
            bool is_in_collasped_range = (mouse_y > f.Top + f.Height) || (mouse_x < f.Left || mouse_x > f.Left + f.Width);
            //设置窗体顶部显示满足的条件
            bool is_in_visiable_range = (mouse_y < 1 && mouse_x >= f.Left && mouse_x <= f.Left + f.Width);
            //设置窗体左边隐藏满足的条件
            bool is_in_collasped_range1 = (mouse_x < f.Left || mouse_x > f.Left + f.Width);
            //设置窗体左边展开满足的条件
            bool is_in_visiable_range1 = (mouse_y >= f.Top) && (mouse_y <= f.Top + f.Height) && (mouse_x >= f.Left && mouse_x <= f.Left + f.Width);

            //顶部隐藏窗体
            if (f.Top < 3 && f.Top >= 0 && f.Left > 3 && is_in_collasped_range)
            {
                System.Threading.Thread.Sleep(300);
                f.Top = -f.ActualHeight - 1;
            }
            //顶部显示窗体
            if (f.Top < 0 && f.Left > 3 && is_in_visiable_range)
            {
                f.Top = 1;
            }
            //左边隐藏窗体
            if (f.Left < 3 && f.Left >= 0 && is_in_collasped_range1)
            {
                System.Threading.Thread.Sleep(300);

                f.Left = -f.ActualWidth + 1;
            }
            //左边显示窗体
            if (f.Left < 0 && is_in_visiable_range1)
            {
                f.Left = 2;
            }

        }
        #endregion
    }
}

【WinForm】实现窗体贴边隐藏

1.新建项目Test，新建窗体Form1，填写如下代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Test
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
        // 当窗体的位置发生改变时，定位窗体的位置
        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;
            }
        }

        // 当窗体的位置改变时，执行 mStopAnhor 
        private void Form1_LocationChanged(object sender, EventArgs e)
        {
            this.mStopAnhor();
        }
        
        /// <summary>  
        /// 时间控件，控制窗体的坐标  
        /// </summary>  
        /// <param name="sender"></param>  
        /// <param name="e"></param>        
        private void timer1_Tick(object sender, EventArgs e)
        {
            if (this.Bounds.Contains(Cursor.Position))
            {
                switch (this.StopAanhor)
                {
                    case AnchorStyles.Top:
                        //窗体在最上方隐藏时，鼠标接触自动出现  
                        this.Location = new Point(this.Location.X, 0);
                        break;
                    //窗体在最左方隐藏时，鼠标接触自动出现  
                    case AnchorStyles.Left:
                        this.Location = new Point(0, this.Location.Y);
                        break;
                    //窗体在最右方隐藏时，鼠标接触自动出现  
                    case AnchorStyles.Right:
                        this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - this.Width, this.Location.Y);
                        break;
                }
            }
            else
            {
                //窗体隐藏时在靠近边界的一侧边会出现2像素原因：感应鼠标，同时2像素不会影响用户视线  
                switch (this.StopAanhor)
                {
                    //窗体在顶部时时，隐藏在顶部，底部边界出现2像素  
                    case AnchorStyles.Top:
                        this.Location = new Point(this.Location.X, (this.Height - 2) * (-1));
                        break;
                    //窗体在最左边时时，隐藏在左边，右边边界出现2像素  
                    case AnchorStyles.Left:
                        this.Location = new Point((-1) * (this.Width - 2), this.Location.Y);
                        break;
                    //窗体在最右边时时，隐藏在右边，左边边界出现2像素  
                    case AnchorStyles.Right:
                        this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - 2, this.Location.Y);
                        break;
                }
            }

        }
    }
}
    

2.需要注意的3个地方：

2.1 Form1窗体的绑定事件

2.2 timer1 控件的设置。

2.3 Form1.Designer.cs里面的设置。
