準備工作
這個窗體繼承子基類窗體FrmBase，如果你對FrmBase還不瞭解，請移步 （十七）c#Winform自定義控制項-基類窗體 查看
氣泡需要支持多個位置顯示，也就是說四面八方都可以顯示，並且支持樣式，自定義大小，另外具有內置的4中模式（成功，錯誤，警告，正常）
開始
定義一些枚舉
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，繼承自FrmBase
屬性
1 private ContentAlignment m_showAlign = ContentAlignment.BottomLeft; 2 3 /// <summary> 4 /// 顯示位置 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 }
提供一些公共函數
