Key Techniques Used in OnPaint()
SmoothingMode
switch (_SmoothingQuality)
{
case SmoothingQualities.None:
e.Graphics.SmoothingMode = SmoothingMode.Default;
break;
case SmoothingQualities.HighSpeed:
e.Graphics.SmoothingMode = SmoothingMode.HighSpeed;
break;
case SmoothingQualities.AntiAlias:
e.Graphics.SmoothingMode = SmoothingMode.AntiAlias;
break;
case SmoothingQualities.HighQuality:
e.Graphics.SmoothingMode = SmoothingMode.HighQuality;
break;
}
LinearGradientMode
LinearGradientMode mode;
switch (_GradientStyle)
{
case GradientStyles.Horizontal:
mode = LinearGradientMode.Horizontal;
break;
case GradientStyles.Vertical:
mode = LinearGradientMode.Vertical;
break;
case GradientStyles.ForwardDiagonal:
mode = LinearGradientMode.ForwardDiagonal;
break;
case GradientStyles.BackwardDiagonal:
mode = LinearGradientMode.BackwardDiagonal;
break;
default:
mode = LinearGradientMode.Vertical;
break;
}
LinearGradientBrush
LinearGradientBrush brush;
switch (_State)
{
case _States.Normal:
brush = new LinearGradientBrush(newRect,
_NormalColorA, _NormalColorB, mode);
switch (_ButtonStyle)
{
case ButtonStyles.Rectangle:
e.Graphics.FillRectangle(brush, newRect);
e.Graphics.DrawRectangle(new
Pen(_NormalBorderColor, 1), newRect);
break;
case ButtonStyles.Ellipse:
e.Graphics.FillEllipse(brush, newRect);
e.Graphics.DrawEllipse(new
Pen(_NormalBorderColor, 1), newRect);
break;
}
e.Graphics.DrawString(this.Text, base.Font,
new SolidBrush(base.ForeColor), textX, textY);
break;
case _States.MouseOver:
brush = new LinearGradientBrush(newRect,
_HoverColorA, _HoverColorB, mode);
switch (_ButtonStyle)
{
case ButtonStyles.Rectangle:
e.Graphics.FillRectangle(brush, newRect);
e.Graphics.DrawRectangle(new
Pen(_HoverBorderColor, 1), newRect);
break;
case ButtonStyles.Ellipse:
e.Graphics.FillEllipse(brush, newRect);
e.Graphics.DrawEllipse(new
Pen(_HoverBorderColor, 1), newRect);
break;
}
e.Graphics.DrawString(this.Text, base.Font,
new SolidBrush(base.ForeColor), textX, textY);
break;
case _States.Clicked:
brush = new LinearGradientBrush(newRect,
_HoverColorA, _HoverColorB, mode);
switch (_ButtonStyle)
{
case ButtonStyles.Rectangle:
e.Graphics.FillRectangle(brush, newRect);
e.Graphics.DrawRectangle(new
Pen(_HoverBorderColor, 2), newRect);
break;
case ButtonStyles.Ellipse:
e.Graphics.FillEllipse(brush, newRect);
e.Graphics.DrawEllipse(new
Pen(_HoverBorderColor, 2), newRect);
break;
}
e.Graphics.DrawString(this.Text, base.Font,
new SolidBrush(base.ForeColor),
textX + 1, textY + 1);
break;
}
