本文整理了Java中org.eclipse.swt.graphics.Device类的一些代码示例，展示了Device类的具体用法。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。Device类的具体详情如下：
包路径：org.eclipse.swt.graphics.Device
类名称：Device

Device介绍

[英]This class is the abstract superclass of all device objects, such as the Display device and the Printer device. Devices can have a graphics context (GC) created for them, and they can be drawn on by sending messages to the associated GC.
[中]此类是所有设备对象（如显示设备和打印机设备）的抽象超类。设备可以为它们创建一个图形上下文（GC），并且可以通过向相关GC发送消息来绘制它们。

public Point getDeviceBounds() {

public static void setGCFont( GC gc, Device device, FontData fontData ) {

  gc.setFont( font );
  font.dispose();
 } else {
  gc.setFont( device.getSystemFont() );
