Java Swing에서 둥근 모서리 BevelBorder를 만드는 방법은 무엇입니까?

Question

3D의 종류이기 때문에 베벨 테두리를 사용하고 싶지만 둥근 모서리의 베벨 보더를 만드는 방법을 모르겠습니다.

둥근 반지름이 너무 작기 때문에 SoftBevelBorder가 작동하지 않습니다. 모서리를 더 둥글게 만드는 방법은 무엇입니까?

Answer 1

다음은 반경을 조정할 수 있습니다 둥근 테두리의 예제가있다 :

베벨하지 않습니다,하지만 당신은 SoftBevelBorder의 소스 코드에서 "bevelness"를 달성하는 방법을 볼 수 있습니다. 당신이 그것을 할 수 있다면, 나는 코드에 흥미가있을 것이다 :

Answer 2

올바른 테두리 모양을 얻으려면 AbstractBorder.paintBorder(...) 메서드를 재정의해야한다. 그렇게하면 메소드와 비슷한 코드를 메소드에 추가 할 수 있습니다.

super.paintBorder(c, g, x, y, width, height); 

Graphics2D g2d = (Graphics2D) g; 
g2d.setRenderingHints(new RenderingHints(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON)); 

Shape clip = g2d.getClip(); 
Area rect = new Area(clip); 
rect.subtract(new Area(new RoundRectangle2D.Double(x, y, width, height, radii, radii))); 
g2d.setClip(rect); 
g2d.setColor(c.getParent().getBackground()); 
g2d.fillRect(0, 0, width, height); 
g2d.setClip(clip); 
g2d.draw(rect); 

이제 두 가지 방법을 사용하여 테두리 주위에 경사 효과를 그릴 수 있지만, 베벨이 원하는 복잡성에 따라하는 것은 당신이 사용하는 방식에 따라 할 수있다. 2 개의 색상을 사용하는 간단한 경사 경계의 경우 이와 비슷한 것을 사용할 수 있습니다. 당신은 4 개 가지 색상을 사용하는 더 복잡한 사영 보더를 사용하려면

g2d.setColor(inner); //Inner Rectangle 
g2d.draw(new RoundRectangle2D.Double(x + 1, y + 1, width - 2, height - 2, radii, radii)); 

g2d.setColor(outer); //Outer Rectangle 
g2d.draw(new RoundRectangle2D.Double(x, y, width - 2, height - 2, radii, radii)); 

그러나, 당신은 javax.swing.border.BevelBorder의 소스 코드를 볼 필요가있을 것이다. 이렇게하면 비슷한 코드가 필요하다는 것을 알 수 있습니다.

double offset = radii/2; 
//Outer 
g2d.setColor(outerH); 
g2d.draw(new Line2D.Double(0, offset, 0, height - 2 - offset)); //Left 
g2d.draw(new Line2D.Double(1 + offset, 0, width - 2 - offset, 0)); //Top 
g2d.draw(new Arc2D.Double(width - radii - 1, 0, radii, radii, 0, 90, Arc2D.OPEN)); //Top Right 
g2d.draw(new Arc2D.Double(0, 0, radii, radii, 90, 90, Arc2D.OPEN)); //Top Left 

//Inner 
g2d.setColor(innerH); 
g2d.draw(new Line2D.Double(1, 1 + offset, 1, height - 3 - offset)); //Left 
g2d.draw(new Line2D.Double(2 + offset, 1, width - 3 - offset, 1)); //Top 
g2d.draw(new Arc2D.Double(width - radii - 2, 1, radii, radii, 0, 90, Arc2D.OPEN)); //Top Right 
g2d.draw(new Arc2D.Double(1, 1, radii, radii, 90, 90, Arc2D.OPEN)); //Top Left 

//Outer 
g2d.setColor(outer); 
g2d.draw(new Line2D.Double(offset, height - 1, width - 1 - offset, height - 1)); //Bottom 
g2d.draw(new Line2D.Double(width - 1, offset, width - 1, height - 2 - offset)); //Right 
g2d.draw(new Arc2D.Double(width - radii - 1, height - radii - 1, radii, radii, 270, 90, Arc2D.OPEN)); //Bottom Right 
g2d.draw(new Arc2D.Double(0, height - radii - 1, radii, radii, 180, 90, Arc2D.OPEN)); //Bottom Left 

//Inner 
g2d.setColor(inner); 
g2d.draw(new Line2D.Double(1 + offset, height - 2, width - 2 - offset, height - 2)); //Bottom 
g2d.draw(new Line2D.Double(width - 2, 1 + offset, width - 2, height - 3 - offset)); //Right 
g2d.draw(new Arc2D.Double(width - radii - 2, height - radii - 2, radii, radii, 270, 90, Arc2D.OPEN)); //Bottom Right 
g2d.draw(new Arc2D.Double(1, height - radii - 2, radii, radii, 180, 90, Arc2D.OPEN)); //Bottom Left 

색상이 모퉁이를 돌면 중간에 멈추는 것이 중요 할 경우 다음 코드를 사용할 수도 있습니다.

double offset = radii/2; 
//Outer 
g2d.setColor(outerH); 
g2d.draw(new Line2D.Double(0, offset, 0, height - 2 - offset)); //Left 
g2d.draw(new Line2D.Double(1 + offset, 0, width - 2 - offset, 0)); //Top 
g2d.draw(new Arc2D.Double(width - radii - 1, 0, radii, radii, 45, 45, Arc2D.OPEN)); //Top Right P1 
g2d.draw(new Arc2D.Double(0, 0, radii, radii, 90, 90, Arc2D.OPEN)); //Top Left 
g2d.draw(new Arc2D.Double(0, height - radii - 1, radii, radii, 180, 45, Arc2D.OPEN)); //Bottom Left P1 

//Inner 
g2d.setColor(innerH); 
g2d.draw(new Line2D.Double(1, 1 + offset, 1, height - 3 - offset)); //Left 
g2d.draw(new Line2D.Double(2 + offset, 1, width - 3 - offset, 1)); //Top 
g2d.draw(new Arc2D.Double(width - radii - 2, 1, radii, radii, 45, 45, Arc2D.OPEN)); //Top Right P1 
g2d.draw(new Arc2D.Double(1, 1, radii, radii, 90, 90, Arc2D.OPEN)); //Top Left 
g2d.draw(new Arc2D.Double(1, height - radii - 2, radii, radii, 180, 45, Arc2D.OPEN)); //Bottom Left P1 

//Outer 
g2d.setColor(outerS); 
g2d.draw(new Line2D.Double(offset, height - 1, width - 1 - offset, height - 1)); //Bottom 
g2d.draw(new Line2D.Double(width - 1, offset, width - 1, height - 2 - offset)); //Right 
g2d.draw(new Arc2D.Double(width - radii - 1, 0, radii, radii, 0, 45, Arc2D.OPEN)); //Top Right P2 
g2d.draw(new Arc2D.Double(width - radii - 1, height - radii - 1, radii, radii, 270, 90, Arc2D.OPEN)); //Bottom Right 
g2d.draw(new Arc2D.Double(0, height - radii - 1, radii, radii, 225, 45, Arc2D.OPEN)); //Bottom Left P2 

//Inner 
g2d.setColor(innerS); 
g2d.draw(new Line2D.Double(1 + offset, height - 2, width - 2 - offset, height - 2)); //Bottom 
g2d.draw(new Line2D.Double(width - 2, 1 + offset, width - 2, height - 3 - offset)); //Right 
g2d.draw(new Arc2D.Double(width - radii - 2, 1, radii, radii, 0, 45, Arc2D.OPEN)); //Top Right P2 
g2d.draw(new Arc2D.Double(width - radii - 2, height - radii - 2, radii, radii, 270, 90, Arc2D.OPEN)); //Bottom Right 
g2d.draw(new Arc2D.Double(1, height - radii - 2, radii, radii, 225, 45, Arc2D.OPEN)); //Bottom Left P2
