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

Shell.setRegion介绍

[英]Sets the shape of the shell to the region specified by the argument. When the argument is null, the default shape of the shell is restored. The shell must be created with the style SWT.NO_TRIM in order to specify a region.

NOTE: This method also sets the size of the shell. Clients should not call #setSize or #setBounds on this shell. Furthermore, the passed region should not be modified any more.
[中]将壳的形状设置为参数指定的区域。当参数为null时，将恢复外壳的默认形状。外壳必须使用SWT样式创建。不修剪以指定区域。
注意：此方法还可以设置壳的大小。客户不应该在这个外壳上调用#setSize或#setBounds。此外，不应再修改已通过的区域。
