本文整理了Java中org.eclipse.swt.graphics.GC.setBackgroundPattern()方法的一些代码示例,展示了GC.setBackgroundPattern()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.setBackgroundPattern()方法的具体详情如下:
包路径:org.eclipse.swt.graphics.GC
类名称:GC
方法名:setBackgroundPattern

GC.setBackgroundPattern介绍

[英]Sets the background pattern. The default value is null.

This operation requires the operating system's advanced graphics subsystem which may not be available on some platforms.
[中]设置背景图案。默认值为null
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: pentaho/pentaho-kettle

return;
gc.setBackgroundPattern( (Pattern) object );
gc.fillRectangle( canvas.getClientArea() );
gc.setBackgroundPattern( null );
return;

/**
 * This method draws the gradient patterns that make up the image. The image
 * consists of 4 rows, each consisting of 4 gradient patterns (total of 16).
 */
@Override
public void paint(GC gc, int width, int height) {

  p.dispose();
  image.dispose();
