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

GC.setLineWidth介绍

[英]Sets the width that will be used when drawing lines for all of the figure drawing operations (that is, drawLine, drawRectangle, drawPolyline, and so forth.

Note that line width of zero is used as a hint to indicate that the fastest possible line drawing algorithms should be used. This means that the output may be different from line width one.
[中]设置为所有地物绘制操作（即，drawLine、drawRectangle、drawPolyline等）绘制线时将使用的宽度。
请注意，线宽为零表示应使用最快的线条绘制算法。这意味着输出可能与线宽不同。
