我想創造出具有槽和地殼線段創建，如下圖所示：
使用矩形
編輯：現在我越來越輪廓窗口中的線段圖但不是在圖編輯器
但是，我沒有得到正是我想要的。我必須使用x , y value and width/height from Rectangle class創建此線段。
下面是代碼：看外形輪廓的方法：
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);
}
}

什麼是你的問題？ – SeniorJD
您只繪製了4行。圖中有5行顯示。另外，檢查你的座標，h1對我來說看起來不對，你需要給兩個Y座標增加高度。檢查他們全部。 – Wossname
@SeniorJd我必須在圖編輯器中創建一個linesegment。我正在使用gmf編輯零件包類來這樣做。 –
