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

Transform.isDisposed介绍

[英]Returns true if the Transform has been disposed, and false otherwise.

This method gets the dispose state for the Transform. When a Transform has been disposed, it is an error to invoke any other method (except #dispose()) using the Transform.
[中]如果已释放转换，则返回true，否则返回false。
此方法获取转换的dispose状态。处理转换后，使用转换调用任何其他方法（除了#dispose（））都是错误的。

public void dispose() {
 gc.dispose();
 if ( transform != null && transform.isDisposed() == false ) {
  transform.dispose();
 }
 for ( Color color : colors ) {
  color.dispose();
 }
 for ( Font font : fonts ) {
  font.dispose();
 }
}
