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

Widget.getStyle介绍

[英]Returns the receiver's style information.

Note that the value which is returned by this method may not match the value which was provided to the constructor when the receiver was created. This can occur when the underlying operating system does not support a particular combination of requested styles. For example, if the platform widget used to implement a particular SWT widget always has scroll bars, the result of calling this method would always have the SWT.H_SCROLL and SWT.V_SCROLL bits set.
[中]返回接收器的样式信息。
请注意，此方法返回的值可能与创建接收器时提供给构造函数的值不匹配。当底层操作系统不支持所请求样式的特定组合时，可能会发生这种情况。例如，如果用于实现特定SWT小部件的平台小部件始终具有滚动条，则调用此方法的结果将始终设置SWT.H_SCROLL和SWT.V_SCROLL位。
