本文整理了Java中org.eclipse.swt.graphics.GC.fillPath()方法的一些代码示例，展示了GC.fillPath()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。GC.fillPath()方法的具体详情如下：
包路径：org.eclipse.swt.graphics.GC
类名称：GC
方法名：fillPath

GC.fillPath介绍

[英]Fills the path described by the parameter.

This operation requires the operating system's advanced graphics subsystem which may not be available on some platforms.
[中]填充参数描述的路径。
此操作需要操作系统的高级图形子系统，该子系统在某些平台上可能不可用。

代码示例

代码示例来源：origin: stackoverflow.com

public static void drawArrow(GC gc, int x1, int y1, int x2, int y2, double arrowLength, double arrowAngle) {
  double theta = Math.atan2(y2 - y1, x2 - x1);
  double offset = (arrowLength - 2) * Math.cos(arrowAngle);

  gc.drawLine(x1, y1, (int)(x2 - offset * Math.cos(theta)), (int)(y2 - offset * Math.sin(theta)));

  Path path = new Path(gc.getDevice());
  path.moveTo((float)(x2 - arrowLength * Math.cos(theta - arrowAngle)), (float)(y2 - arrowLength * Math.sin(theta - arrowAngle)));
  path.lineTo((float)x2, (float)y2);
  path.lineTo((float)(x2 - arrowLength * Math.cos(theta + arrowAngle)), (float)(y2 - arrowLength * Math.sin(theta + arrowAngle)));
  path.close();

  gc.fillPath(path);

  path.dispose();
}

...

gc.setLineWidth(1);
gc.setForeground(display.getSystemColor(SWT.COLOR_BLACK));
gc.setBackground(display.getSystemColor(SWT.COLOR_BLACK));
drawArrow(gc, x1, y1, x2, y2, 8, Math.toRadians(40));
