用處及效果
準備作業
沒什么可準備的，直接往下看吧
開始
添加一個類UCPanelQuote繼承 Panel
添加2個屬性
1 /// <summary> 2 /// The border color 3 /// </summary> 4 private Color borderColor = LineColors.Light; 5 6 /// <summary> 7 /// Gets or sets the color of the border. 8 /// </summary> 9 /// <value>The color of the border.</value>10 [Description("邊框顏色"), Category("自定義")]11 public Color BorderColor12 {13 get { return borderColor; }14 set15 {16 borderColor = value;17 this.Invalidate();18 }19 }20 21 /// <summary>22 /// The left color23 /// </summary>24 private Color leftColor = StatusColors.Danger;25 26 /// <summary>27 /// Gets or sets the color of the left.28 /// </summary>29 /// <value>The color of the left.</value>30 [Description("左側顏色"), Category("自定義")]31 public Color LeftColor32 {33 get { return leftColor; }34 set35 {36 leftColor = value;37 this.Invalidate();38 }39 }
為了畫邊框和左邊的顏色，設定一下Padding
1 public UCPanelQuote()2 : base()3 {4 Padding = new Padding(5, 1, 1, 1);5 }
重繪
1 protected override void OnPaint(PaintEventArgs e) 2 { 3 base.OnPaint(e); 4 e.Graphics.SetGDIHigh(); 5 6 e.Graphics.DrawLines(new Pen(borderColor), new Point[] 7 { 8 new Point(e.ClipRectangle.Left,e.ClipRectangle.Top), 9 new Point(e.ClipRectangle.Right-1,e.ClipRectangle.Top),10 new Point(e.ClipRectangle.Right-1,e.ClipRectangle.Bottom-1),11 new Point(e.ClipRectangle.Left,e.ClipRectangle.Bottom-1),12 new Point(e.ClipRectangle.Left,e.ClipRectangle.Top)13 });14 15 e.Graphics.FillRectangle(new SolidBrush(leftColor), new Rectangle(0, 0, 5, this.Height));16 }
