Java Gridbag missalign-第二行中的最后一个单元格显示在第一行中
我正在为表单使用GB布局。目前有两行,每行由6个元素组成(第一行包含标签,第二行包含文本字段)。我的问题是,应该在x5y1中显示的元素在x6y0中显示。你能指出我犯的错误吗Java Gridbag missalign-第二行中的最后一个单元格显示在第一行中,java,layout,gridbaglayout,Java,Layout,Gridbaglayout,我正在为表单使用GB布局。目前有两行,每行由6个元素组成(第一行包含标签,第二行包含文本字段)。我的问题是,应该在x5y1中显示的元素在x6y0中显示。你能指出我犯的错误吗 public GUI() { super("Bla"); GridBagLayout layout = new GridBagLayout(); setLayout(layout); GridBagConstraints gbc = new GridBagConstraints();

使用
GridBagLayout
您需要调用
添加(零部件、对象约束)
添加您忘记的最后一个组件GridBagConstraints
objectcon.add(txtPresence)代码>。若并没有它,组件将放在第一行的最后一个组件之后,因为这是它将看到的第一个不受约束的可用空间(它只会使Y=0,并转到下一个可用的X)。如果您要在JPanel
中添加组件,且该组件带有GridBagLayout
而不带有GridBagConstraints
对象,则它们将放在一行中
请记住使用GridBagConstraints
对象设置weights
、fill
和anchor
你也可以在github上看到我的回购协议。它包含一个演示如何工作。不过,您仍然应该了解GridBagLayout
的工作原理
SSCCE:(快速修复代码)
哦,我的。。。非常感谢,很抱歉打扰你问这个问题。@Faire是的,没问题。这种事总是发生在我身上。这就是为什么我创建了GridBagManager,并且我的抽象面板有自己的add()
方法,它调用add(comp,gbc)
,GridBagConstraints gbc
作为此类的一个字段。就这么简单。查一查,快乐编码!
