本文整理了Java中org.netbeans.api.visual.widget.Widget.getBounds()方法的一些代码示例，展示了Widget.getBounds()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.getBounds()方法的具体详情如下：
包路径：org.netbeans.api.visual.widget.Widget
类名称：Widget
方法名：getBounds

Widget.getBounds介绍

[英]Returns the resolved bounds of the widget. The bounds are specified relatively to the location of the widget.

The location is resolved/set by calling resolveBounds method which should be called from Layout interface implementation only. Therefore the corrent value is available only after the scene is validated (SceneListener.sceneValidated method). Before validation a previous/obsolete or null value could be returned. See Layout section in documentation.
[中]返回小部件的已解析边界。边界是相对于小部件的位置指定的。
通过调用resolveBounds方法解析/设置位置，该方法应仅从Layout接口实现调用。因此，只有在验证场景后，相应的值才可用（SceneListener.sceneValidated方法）。在验证之前，可以返回以前的/过时的或null值。请参阅文档中的布局部分。

private void checkViewLocationInBounds (Point location, Widget v, int dx, int dy) {

  if (dy < 0 && location.y > view.y)
    location.y = view.y;
  if (dx > 0 && location.x + view.width < viewport.x + viewport.width)
    location.x = viewport.x + viewport.width - view.width;
  if (dy > 0 && location.y + view.height < viewport.y + viewport.height)
    location.y = viewport.y + viewport.height - view.height;
