Java 选择布局问题
大家好，我正在尝试制作一个顶部带有导航栏的屏幕，但不确定哪种布局最适合使用。基本上我希望屏幕看起来像：
[Nav Panel Up top, One row]
[ ^ ]
[ | ]
[ Empty Panel ]
[ | ]
[ | ]
[ | ]
[ ^ ]
嵌套面板包含导航按钮。
我的问题是，我应该使用 GridBagLayout 并将其设置为大约 10 行，然后让空面板展开其中的 9 行，还是 Java 中有更好的布局可以让我做到这一点？
Hey guys I'm trying to make a screen with a navigation bar at the top and am unsure what layout would be the best to use. Basically I want the screen to look like:
[Nav Panel Up top, One row]
[ ^ ]
[ | ]
[ Empty Panel ]
[ | ]
[ | ]
[ | ]
[ ^ ]
The nested panel contains the navigation buttons.
My question is, should I use a GridBagLayout and just set it to having like 10 rows and have the empty panel expand 9 of them or is there a better layout in Java that would allow me to do this?

“导航栏”听起来像是它本身也可以是一个组件。如果额外的嵌套级别不是问题，我只需使用 < code>BorderLayout，放置导航栏组件
NORTH和空面板 (我想 UI 的其余部分在CENTER。我更喜欢使用 GridBagLayout 来制作复杂的控件，这些控件无法再拆分为子面板，并且需要有很多边缘需要对齐的布局 - 对于这种情况，它的灵活性有点过大了。 （当然，它仍然非常适合这项任务，只是不是完成它的最简单方法。）
The "navigation bar" sounds like it could as well be a component on its own. If the extra level of nesting isn't a problem, I'd just use
BorderLayout, put the nav bar componentNORTH, and the empty panel (where the rest of the UI is I suppose) into theCENTER.I prefer
GridBagLayoutfor making complex controls that can't be split into subpanels anymore, and need layouts where there are a lot of edges to align – its flexibility is a little overkill for this case. (Of course it's still perfectly suitable for this task, just not the simplest way to accomplish it.)您不会想在 GridBagLayout 中使用 9 行来容纳一个组件；它比那更强大。相反，为导航面板的 GridBagConstraints 提供一个
权重为0，空面板的权重为1（或任何积极的 数字）。这将导致空面板占用任何额外空间。You wouldn't want to use 9 rows in
GridBagLayoutto hold one component; it is more powerful than that. Instead give theGridBagConstraintsfor the navigation panel aweightyof0and the empty panel aweightyof1(or any positive number). This will cause the empty panel to take up any extra space.
