我正在尝试创建一个具有槽和外壳的线段，如下所示：
编辑：现在我在大纲窗口中得到线段图，但在图表编辑器中没有
但是我没有得到我想要的。我必须仅使用x , y value and width/height from Rectangle class.
下面是代码：见轮廓形状方法：
package pipenet.diagram.edit.parts;
import org.eclipse.draw2d.Graphics;
import org.eclipse.draw2d.Shape;
import org.eclipse.draw2d.geometry.Rectangle;
import org.eclipse.swt.SWT;
public class Line3 extends Shape {
public Line3() {
this.setAntialias(SWT.ON);
}
@Override
protected void fillShape(Graphics graphics) {
graphics.pushState();
graphics.setFillRule(SWT.FILL_WINDING);
graphics.popState();
}
@Override
protected void outlineShape(Graphics graphics) {
Rectangle r = getBounds().getCopy();
// v 1
graphics.drawLine(r.x, r.y+r.height, r.x, r.y);
graphics.drawLine(r.x, r.y, r.x+r.width/2, r.y);
graphics.drawLine(r.x+r.width/2, r.y, r.x+r.width/2, r.y+r.height);
graphics.drawLine(r.x+r.width/2, r.y+r.height, r.x+r.width, r.y+r.height);
graphics.drawLine(r.x+r.width, r.y+r.height, r.x+r.width, r.y);
}
@Override
public void paintFigure(Graphics graphics) {
// TODO Auto-generated method stub
super.paintFigure(graphics);
}
}
