winform基礎控制元件樣式重繪
閒來無事，把一些自認為比較能夠用的上的做一個記錄，以備後用，也能在淡忘之際能夠重新記憶。
主要是針對winform中的一些基本控制元件做一個樣式更改，原因是自帶的控制元件在某些方面達不到要求，其實就是美觀的問題。
如下：
1、繪製圓角Button
/// <summary>
/// 圓角Button
/// </summary>
/// <param name="sender">buttonName</param>
/// <param name="p_1">10</param>
/// <param name="p_2">0.1</param>
public static void DrawButton(Control sender, int p_1, double p_2)
{
GraphicsPath oPath = new GraphicsPath();
oPath.AddClosedCurve(new Point[]{
new Point(0,sender.Height/p_1),
new Point(sender.Width/p_1,0),
new Point(sender.Width - sender.Height/p_1,0),
new Point(sender.Width,sender.Height/p_1),
new Point(sender.Width,sender.Height - sender.Height / p_1),
new Point(sender.Width - sender.Width / p_1,sender.Height),
new Point(sender.Width / p_1,sender.Height),
new Point(0,sender.Height - sender.Height / p_1)
},
(float)p_2);
sender.Region = new Region(oPath);
}
呼叫： Button btn = (Button)sender;
ControlDraw.DrawButton(btn, 10, 0.1);
2、繪製圓角窗體
/// <summary>
/// 圓角窗體
/// </summary>
/// <param name="rect"></param>
/// <param name="radius"></param>
/// <returns></returns>
public static GraphicsPath GetRoundedRecPath(Rectangle rect, int radius)
{
int diameter = radius;
Rectangle arcRect = new Rectangle(rect.Location, new Size(diameter, diameter));
GraphicsPath path = new GraphicsPath();
path.AddArc(arcRect, 180, 90);
arcRect.X = rect.Right - diameter;
path.AddArc(arcRect, 270, 90);
arcRect.Y = rect.Bottom - diameter;
path.AddArc(arcRect, 0, 90);
arcRect.X = rect.Left;
path.AddArc(arcRect, 90, 90);
path.CloseFigure();
return path;
}
呼叫：窗體InstrumentStateFrm的Resize事件
private void InstrumentStateFrm_Resize(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Normal)
{
GraphicsPath formPath = new GraphicsPath();
Rectangle rect = new Rectangle(0, 0, this.Width, this.Height);
formPath = ControlDraw.GetRoundedRecPath(rect, 50);
this.Region = new Region(formPath);
}
else
{
this.Region = null;
}
}
3、繪製圓角Panel
/// <summary>
/// 圓角panel
/// </summary>
/// <param name="rectangle">panel1_Paint事件e.ClipRectangle</param>
/// <param name="g">e.Graphics</param>
/// <param name="_radius">圓角弧度50</param>
/// <param name="cusp">true = 右邊突出尖角，false = 圓角Panel</param>
/// <param name="begin_color">顏色</param>
/// <param name="end_color">顏色</param>
public static void DrawPanle(Rectangle rectangle,Graphics g,int _radius,bool cusp,Color
begin_color,Color end_color)
{
int span = 2;
g.SmoothingMode = SmoothingMode.AntiAlias;
LinearGradientBrush myLinearGradientBrush = new LinearGradientBrush(rectangle,
begin_color, end_color, LinearGradientMode.Vertical);
if (cusp)
{
span = 10;
PointF p1 = new PointF(rectangle.Width - 12, rectangle.Y + 10);
PointF p2 = new PointF(rectangle.Width - 12, rectangle.Y + 30);
PointF p3 = new PointF(rectangle.Width, rectangle.Y + 20);
PointF[] ptsArray = { p1, p2, p3 };
g.FillPolygon(myLinearGradientBrush, ptsArray);
}
g.FillPath(myLinearGradientBrush, DrawRoundRect(rectangle.X, rectangle.Y,
rectangle.Width - span, rectangle.Height - 1, _radius));
}
/// <summary>
/// 畫橢圓
/// </summary>
/// <param name="x"></param>
/// <param name="y"></param>
/// <param name="width"></param>
/// <param name="height"></param>
/// <param name="radius"></param>
/// <returns></returns>
public static GraphicsPath DrawRoundRect(int x,int y,int width,int height,int radius)
{
GraphicsPath gp = new GraphicsPath();
gp.AddArc(x, y, radius, radius, 180, 90);
gp.AddArc(width - radius, y, radius, radius, 270, 90);
gp.AddArc(width - radius, height - radius, radius, radius, 0, 90);
gp.AddArc(x, height - radius, radius, radius, 90, 90);
return gp;
}
呼叫：panel的Paint事件
private void panel1_Paint(object sender, PaintEventArgs e)
{
//ControlDraw.DrawPanle(e.ClipRectangle, e.Graphics, 50, false, Color.FromArgb(224, 224,
224), Color.FromArgb(224, 224, 224));
ControlDraw.DrawPanle(e.ClipRectangle, e.Graphics, 5, false, Color.FromName("Control"),
Color.FromName("Control"));
base.OnPaint(e);
}
