GridBagLayout 类需要一个 GridBagConstraints 对象。如果传递正确的约束对象类型时失败,则会导致 IllegalArgumentException。 如果当前布局管理器实现了 LayoutManager2,则在其上调用 LayoutManager2.addLayoutComponent(Component,Object)。如果当前布局管理器没有实现 LayoutManager2,并且约束是一个 String,则在其上调用 ...
GridLayout允许你构建一个放置组件的表格 在向表格里面添加组件的时候 它们将按照从左到右 从上到下的顺序加入 在构造器中要指定需要的行数和列数 它们将均匀分布在窗体上 GridBagLayout GridBagLayout提供了强大的控制功能 包括精确判断视窗区域如何布局 以及视窗大小变化的时候如何重新放置组件 不过 它也是最复杂的布局...
TheGridBagLayoutandGridBagConstraintsclasses each have only one constructor, with no arguments. Instead of invoking methods on aGridBagConstraintsobject, you manipulate its instance variables, as described inSpecifying Constraints. Generally, the only method you invoke on aGridBagLayoutobject issetConstraints...

在获得一个以Zip格式压缩的文件之后,需要将其进行解压缩,还原成压缩前的文件。若是使用Java自带的压缩工具包来实现解压缩文件到指定文件夹的功能,因为jdk提供的zip只能按UTF-8格式处理,而Windows系统中文件名是以GBK方式编码的,所以如果是解压一个包含中文文件名的zip包,会报非法参数异常,如图所示: ...

In java we can implement Layouts using Boxlayout and Gridbaglayout. BOX LAYOUT:BoxLayout is unlike most layout managers which just require you to create the layout manager, and associate the layout manager with the Container. Instead, the BoxLayout constructor requires you to pass the Container ...
TableLayout (the other one from Sun, webpage no longer available) uses 2D arrays of percentages, sizes, and flags to describe the table and how it should be sized. This approach has the same problems as GridBagLayout. PageLayoutuses a concise Java API to describe the table. ...
