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

GC.stringExtent介绍

[英]Returns the extent of the given string. No tab expansion or carriage return processing will be performed.

The extent of a string is the width and height of the rectangular area it would cover if drawn in a particular font (in this case, the current font in the receiver).
[中]返回给定字符串的范围。不执行制表符扩展或回车处理。
字符串的范围是以特定字体绘制时将覆盖的矩形区域的宽度和高度（在本例中为接收器中的当前字体）。

void layout() {
 Composite parent = canvas.getParent();
 Rectangle rect = parent.getClientArea();
 int width = 0;
 String[] items = list.getItems();
 GC gc = new GC( list );
 for ( int i = 0; i < objects.length; i++ ) {
  width = Math.max( width, gc.stringExtent( items[i] ).x );
 }
 gc.dispose();
 Point size1 = start.computeSize( SWT.DEFAULT, SWT.DEFAULT );
 Point size2 = stop.computeSize( SWT.DEFAULT, SWT.DEFAULT );
 Point size3 = check.computeSize( SWT.DEFAULT, SWT.DEFAULT );
 Point size4 = label.computeSize( SWT.DEFAULT, SWT.DEFAULT );
 width = Math.max( size1.x, Math.max( size2.x, Math.max( size3.x, width ) ) );
 width = Math.max( 64, Math.max( size4.x, list.computeSize( width, SWT.DEFAULT ).x ) );
 start.setBounds( 0, 0, width, size1.y );
 stop.setBounds( 0, size1.y, width, size2.y );
 check.setBounds( 0, size1.y + size2.y, width, size3.y );
 label.setBounds( 0, rect.height - size4.y, width, size4.y );
 int height = size1.y + size2.y + size3.y;
 list.setBounds( 0, height, width, rect.height - height - size4.y );
 text.setBounds( width, 0, rect.width - width, rect.height );
 canvas.setBounds( width, 0, rect.width - width, rect.height );
