代码有点难读
首先,我建议不要在容器之间共享相同的GridBagLayout
实例
gridbag = new GridBagLayout();
setLayout(gridbag);
//...
mainPanel = new JPanel(gridbag);
这可能会导致问题,相反,为每个容器提供它们自己的GridBagLayout
这意味着您将无法执行类似于gridbag.setConstraints(cont,gbc)的操作事实上,根据您编写代码的方式,我可能会建议您不要使用它,相反,请使用类似于main.add(cont,gbc)
的方法,它会将约束传递给当前分配的布局管理器
其次,在正常情况下,gridwidth
和gridheight
不应小于1
,否则,您会遇到问题
所以你应该使用更像
addcomponents(new JLabel("Policy #"), mainPanel, 0, 0, 1, 1, 0, 0, GridBagConstraints.NONE, GridBagConstraints.NORTHWEST);
addcomponents(pTextField, mainPanel, null, 2, 0, 2, 1, 0, 0, GridBagConstraints.HORIZONTAL, GridBagConstraints.WEST);
虽然这没关系,但由于参数的数量,很容易忘记哪个参数做了什么。我可能会考虑使用构造函数模式来构建约束,但这是我的/P>请确保您所编译的代码可以被编译和执行。也试着压缩你的代码,准确地显示出你认为问题可能出现的地方,这是我不确定的,但我坚信它是我创建的方法。你提供的代码没有实际添加任何组件到你的容器中,事实上,你的代码生成了一个java.lang.IllegalArgumentException
,它为我运行,我想我漏掉了一些东西,我只是粘贴了我认为可疑的错误代码
