在网格布局JPanels差距 [英] Gap between JPanels in GridLayout
本文介绍了在网格布局JPanels差距的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
下code生产中的9个按键9台单独的JPanels。九JPanels安排到使用网格布局基地的JPanel。然后，这个基地的JPanel放置到使用边界布局中的contentPane。我使用这些Jbutton边界和每一个人的JPanel明确界定它们的间距。每个JPanel的内这些Jbutton看起来不错，但有这是造成这是窃听了我的地狱的双重线的外观JPanels之间的差距。我试着将每一个人的JPanel到直接的contentPane但什么都不做。完全难住了，不知道如果任何人有什么建议吗？
The code below produces nine individual JPanels in which are 9 buttons. The nine JPanels are arranged onto a base JPanel using GridLayout. This base JPanel is then placed onto the ContentPane using Border Layout. I'm using borders for the JButtons and each individual JPanel to clearly define their separation. The JButtons inside each JPanel look fine but there is a gap between the JPanels which is causing the appearance of a double line which is bugging the hell out of me. I've tried adding each individual JPanel onto the ContentPane directly but this does nothing. Totally stumped and wondering if anyone has any suggestions?
P.S。我知道重复code需求质量在一个糟糕的方式重新分解和会，这只是实物模型的目的。
P.S. I know the mass of duplicate code needs re-factoring in a bad way and it will, this is just for mock-up purposes.
谢谢，

推荐答案
我相信这是因为布局管理器的JPanel s是的FlowLayout ，其中包括保证金。当您创建面板，设置其布局网格布局，这将给你0保证金。
I believe it's because the Layout Manager for JPanels is FlowLayout which includes a margin. When you create the panels, set their layout to GridLayout which will give you 0 margin.
另外你做了 setVgap（0）; 和 setHgap（0）; 为网格布局？
