准备工作

这个窗体继承子基类窗体FrmBase,如果你对FrmBase还不了解,请移步 (十七)c#Winform自定义控件-基类窗体 查看

气泡需要支持多个位置显示,也就是说四面八方都可以显示,并且支持样式,自定义大小,另外具有内置的4中模式(成功,错误,警告,正常)

开始

定义一些枚举

 1  public enum TipsSizeMode
 2     {
 3         Small,
 4         Medium,
 5         Large,
 6         None
 7     }
 8     public enum TipsState
 9     {
10         Default = -1,
11         Success = -6566849,
12         Info = -12477983,
13         Warning = -357816,
14         Error = -1097849
15     }

添加Form,命名FrmTips,继承自FrmBase

属性

 1  private ContentAlignment m_showAlign = ContentAlignment.BottomLeft;
 2 
 3         /// <summary>
 4         /// 显示位置
 5         /// </summary>
 6         public ContentAlignment ShowAlign
 7         {
 8             get { return m_showAlign; }
 9             set { m_showAlign = value; }
10         }
11 
12         private static List<FrmTips> m_lstTips = new List<FrmTips>();
13 
14         private int m_CloseTime = 0;
15 
16         public int CloseTime
17         {
18             get { return m_CloseTime; }
19             set
20             {
21                 m_CloseTime = value;
22                 if (value > 0)
23                     timer1.Interval = value;
24             }
25         }

提供一些公共函数

 8         public static void ClearTips()
 9         {
10             for (int i = m_lstTips.Count - 1; i >= 0; i--)
11             {
12                 FrmTips current = m_lstTips[i];
13                 if (!current.IsDisposed)
14                 {
15                     current.Close();
16                     current.Dispose();
17                 }
18             }
19             m_lstTips.Clear();
20         }
21         #endregion
22  
23         /// <summary>
24         /// 重置倒计时
25         /// </summary>
26         public void ResetTimer()
27         {
28             if (m_CloseTime > 0)
29             {
30                 timer1.Enabled = false;
31                 timer1.Enabled = true;
32             }
33         }

用处及效果

用处:向用户提示一些信息,但是这些信息又不是非常重要,不需要用户确定的时候可以用到这个东西

效果:

调用示例

1             FrmTips.ShowTipsError(this, "Error提示信息");
2             FrmTips.ShowTipsInfo(this, "Info提示信息");
3             FrmTips.ShowTipsSuccess(this, "Success提示信息");
4             FrmTips.ShowTipsWarning(this, "Warning提示信息");
