NetBeans IDE问题添加网格布局

标签： java netbeans grid-layout sudoku

enter image description here我用net beans程序创建了我的应用程序设计。我想添加一个类似于数独的30 * 30网格布局。实际上我试图为地图绘制一个30 * 30的正方形。但是，我无法将该视图添加到我的代码中。我搜索了很多地方，但我无法找到答案。我对您的想法持开放态度。有人可以帮我解决这个问题吗？谢谢 ！

答案 0 :(得分：2)

如果您正在使用Netbeans，则可以使用GUI Builder执行此操作。只需转到设计视图，右键单击要用于此的基础容器（某些JPanel），转到上下文菜单中的“设置布局”选项，然后选择“网格布局”。要编辑其属性，请转到“导航”窗口（通常在左侧），浏览组件，直到看到有问题的容器，折叠它并选择GridLayout。您现在可以在属性窗口（通常在右侧）更改某些属性，如行和列。然后，将其他组件拖到该容器的顶部。

尽管如此，根据您的描述，我想知道您真正想要的是JTable，这是一个可以让您在网格中显示数据的组件。
