今天给各位分享javajcurses的知识,其中也会对进行解释,如果能碰巧解决你现在面临的问题,别忘了关注本站,现在开始吧!

本文目录一览:

Java JTree 默认展开

在初始化时让它的根节点展开就行了,具体用函数

public void expandRow(int row)

确保指定行中的节点展开,并且可查看。

如果 row 0 或 = getRowCount,则此方法无效。

参数:

row - 指定一个显示行的整数,其中 0 表示显示的第一行

例如让根节点展开 expandRow(0),再把二级节点的根节点也这样设置一下就都可以展开了

eclipse java求帮忙!!!!!!

The ability to do this is a property of the terminal, not the language. So in principal, if you're connected to a sufficiently capable terminal emulator, then yes, of course it's possible.

The purpose of a library like ncurses is to abstract away the gory details of terminal-dependent cursor movement, etc. You don't need something like ncurses, you could always just directly emit the appropriate codes for your target terminal.

By, "is there an equivalent method in Java," do you mean are there libraries which also can provide you terminal-agnostic abstractions? Yes (see the other responses). But nothing is going to make every host system to the JVM provide a VT100 emulator. For example, good luck on Windows. In this sense, 2D graphics in Java are more universal than the terminal environment!

JCurses (Java port of ncurses library from C) is one possibility

提供这种功能的是控制台,你可以使用JCurses这个类库办到,本来我想在linux下测试的,不过好像没有64位的,你要尝试,祝你好运

java中jlabel什么意思

1、LEFT、RIGHT、CENTER、LEADING 、TRAILING等参数表示label中内容对齐方式:左对齐、右对齐、居中、靠顶对齐、靠下对齐\x0d\x0a2、可以。 有构造函数 \x0d\x0aJLabel(Icon image) \x0d\x0aJLabel(Icon image,int horizontalAlignment)\x0d\x0aJLabel(String text,Icon image,int horizontalAlignment) \x0d\x0a参数说明:\x0d\x0aString text:标签中显示文字\x0d\x0a \x0d\x0aIcon image: 图片对象,需要使用ImageIcon子对象创建, Icon image=new ImageIcon(String filename); filename:图片本地路径\x0d\x0a \x0d\x0ahorizontalAlignment:对齐方式,就是1中的那些常量
