Winform自定义弹窗二

一：创建出一个form新窗体，绘制出大概的样式。

1.属性：

　　StartPosition：CenterScreen 初始位置设为居中

　　FormBorderStyle：None 不要边框

　　我这里拖入了一个Panel控件用于装提示框内容背景颜色设置为：WhiteSmoke 类似于灰白色一样的。

　　然后在Panel控件里拖入一个PictrueBox组件用于显示消息框图标

　　在加入一个Button搞定。界面就简单的做出来了

二.窗体操作

1.拖动：

　　由于窗体失去了边框，无法拖动需要自己手动加入点击窗体时拖动的事件

 1  //移动窗体
 2         const int WM_NCLBUTTONDOWN = 0xA1;
 3         const int HT_CAPTION = 0x2;
 4         [System.Runtime.InteropServices.DllImport("user32.dll")]
 5         static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);
 6 //给窗体添加MouseDown事件
 7         private void Form_Alert_MouseDown(object sender, MouseEventArgs e)
 8         {
 9             if (e.Button == MouseButtons.Left & this.WindowState == FormWindowState.Normal)
10             {
11                 //移动窗体
12                 this.Capture = false;
13                 SendMessage(Handle, WM_NCLBUTTONDOWN, HT_CAPTION, 0);
14             }

 1  private void timer1_Tick(object sender, EventArgs e)
 2         {
 3             switch (this.action)
 4             {
 5                 case enmAction.Start:
 6                     timer1.Interval = 1;
 7                     if (this.Opacity < 1.0)
 8                     {
 9                         this.Opacity += 0.1;
10                     }
11                     break;
12                 case enmAction.Close:
13                     timer1.Interval = 1;
14                     this.Opacity -= 0.1;
15                     if (this.Opacity == 0.0)
16                     {
17                         base.Close();
18                     }
19                     break;
20             }
21         }

15         }

2.圆角：

 1         /// <summary>
 2         /// 设置窗体的Region
 3         /// </summary>
 4         public void SetWindowRegion()
 5         {
 6             GraphicsPath FormPath;
 7             Rectangle rect = new Rectangle(0, 0, this.Width, this.Height);
 8             FormPath = GetRoundedRectPath(rect, 25);
 9             this.Region = new Region(FormPath);
10         }
11         /// <summary>
12         /// 绘制圆角路径
13         /// </summary>
14         /// <param name="rect"></param>
15         /// <param name="radius"></param>
16         /// <returns></returns>
17         private GraphicsPath GetRoundedRectPath(Rectangle rect, int radius)
18         {
19             int diameter = radius;
20             Rectangle arcRect = new Rectangle(rect.Location, new Size(diameter, diameter));
21             GraphicsPath path = new GraphicsPath();
22             // 左上角
23             path.AddArc(arcRect, 180, 90);
24             // 右上角
25             arcRect.X = rect.Right - diameter;
26             path.AddArc(arcRect, 270, 90);
27             // 右下角
28             arcRect.Y = rect.Bottom - diameter;
29             path.AddArc(arcRect, 0, 90);
30             // 左下角
31             arcRect.X = rect.Left;
32             path.AddArc(arcRect, 90, 90);
33             path.CloseFigure();//闭合曲线
34             return path;
35         }
36        //给窗体添加该变大小事件
37        private void Form_Alert_Resize(object sender, EventArgs e)
38         {
39             //重设圆角
40             SetWindowRegion();
41         }

3.内容居中

        //设置控件居中
        private void SetCenterControl()
        {
            //标题居中
            this.labTitle.Left = (this.Width - labTitle.Width) / 2;
            //内容居中
            this.labText.Left = (this.Width + AlertIcon.Width - labText.Width) / 2;
            if (labText.Width < 200)
            {
                //如果内容长度过短 就只以窗体宽度居中 
                this.labText.Left = (this.Width - labText.Width) / 2;
            }
            this.labText.MaximumSize = new Size(300,0);
            this.labText.Top = (this.Height - labText.Height) / 2 - (btnOk.Height + 5);
        }
        private void Form_Alert_Resize(object sender, EventArgs e)
        {
            SetWindowRegion();
            //在窗体大小改变事件中调用
            SetCenterControl();
        }

三：枚举动作

 1 //窗口类型
 2 public enum enmType
 3         {
 4             Success,
 5             Error,
 6             Info,
 7             Warn
 8         }
 9 //动作
10         public enum enmAction
11         {
12             Start,
13             Close
14         }
15 //记录当前动作
16         private Form_Alert.enmAction action;

四：显示

1.拖入一个定时器用来处理窗体的显示过度和行动事件

　　监听每1毫秒当前弹框的动作, 设置Opacity透明度，用来过度显示和关闭, 不然导致很僵硬。

 1  private void timer1_Tick(object sender, EventArgs e)
 2         {
 3             switch (this.action)
 4             {
 5                 case enmAction.Start:
 6                     timer1.Interval = 1;
 7                     if (this.Opacity < 1.0)
 8                     {
 9                         this.Opacity += 0.1;
10                     }
11                     break;
12                 case enmAction.Close:
13                     timer1.Interval = 1;
14                     this.Opacity -= 0.1;
15                     if (this.Opacity == 0.0)
16                     {
17                         base.Close();
18                     }
19                     break;
20             }
21         }

五：定义一个显示方法

 1 // 内容 弹框类型 标题
 2 public void Alert(string Content, enmType type, string Title)
 3         {
 4             this.Opacity = 0.0;
 5             switch (type)
 6             {
 7                 //根据类型设置弹框的颜色和图标
 8                 case enmType.Success:
 9                     this.BackColor = Color.SeaGreen;
10                     this.btnOk.BackColor= Color.SeaGreen;
11                     this.AlertIcon.Image = Resources.Success_gray;
12                     break;
13                 case enmType.Error:
14                     this.BackColor = Color.DarkRed;
15                     this.btnOk.BackColor = Color.DarkRed;
16                     this.AlertIcon.Image = Resources.Error_gray;
17                     break;
18                 case enmType.Info:
19                     this.BackColor = Color.RoyalBlue;
20                     this.btnOk.BackColor = Color.RoyalBlue;
21                     this.AlertIcon.Image = Resources.Info_gray;
22                     break;
23                 case enmType.Warn:
24                     this.BackColor = Color.DarkOrange;
25                     this.btnOk.BackColor = Color.DarkOrange;
26                     this.AlertIcon.Image = Resources.Warn_gray;
27                     break;
28             }
29             this.Show();//显示
30             this.labTitle.Text = Title;
31             this.labText.Text = Content;
32             this.action = enmAction.Start;
33             this.timer1.Interval = 1;
34             this.timer1.Start();
35             RightVoiceAndHint();//这是定义的一个播放提示音的方法
36         }

六：最后调用显示

　　在新建第二个新窗体主程序，弹出提示框，看看效果

 1 //对话框显示方法
 2         public void MoudelAlert(string Content, Form_Alert.enmType type, string Title = "提示")
 3         {
 4             Form_Alert Moudel = new Form_Alert();
 5             Moudel.Alert(Content, type, Title);
 6         }
 7         //弹出成功对话框
 8         private void btn_AlSuccess_Click(object sender, EventArgs e)
 9         {
10             this.MoudelAlert("Alert Success...", Form_Alert.enmType.Success,"温馨提示");
11         }
12         //警告
13         private void btn_AlWarn_Click(object sender, EventArgs e)
14         {
15             this.MoudelAlert("Alert Warning...", Form_Alert.enmType.Warn);
16         }
17         //错误
18         private void btn_AlError_Click(object sender, EventArgs e)
19         {
20             this.MoudelAlert("Alert Error...", Form_Alert.enmType.Error);
21         }
22         //提示
23         private void btn_AlInfo_Click(object sender, EventArgs e)
24         {
25             this.MoudelAlert("Alert Info...", Form_Alert.enmType.Info);
26         }
