nimbus

Is there a way to have the Nimbus Look&Feel render its own windows decorations for a top level JFrame ? I've been digging through the Internet, and I'm starting to suspect it might not be possible at all. Has anyone actually succeeded with (and cared about) that? Nimbus decorations are nice and neat for internal frames , but apparently there is no way to have the same effect on JFrame s and JDialog s. I tried nimbusx (Nimbus Extensions), a library that subclasses JFrame and JDialog and allegedly applies nimbus-styled decorations to them (then you just have to instantiate nimbusx classes

I am using Nimbus Look and feel. I needs to change the Background color and foreground color of the tab in JTabbedPane but the color doesn't set in JTabbedPane. I tried setForeground(), setForegroundAt(), setBackground() and setBackgroundAt() methods but it isnt works.This is my code public class TabbedPaneDemo extends JFrame { TabbedPaneDemo() { try { UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel"); } catch(Exception ex) {} setLayout(new BorderLayout()); setBounds(100, 100, 800, 500); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JTabbedPane jt = new JTabbedPane

The JTableHaeder has no 'pressed' highlighting by default. (Nimbus) NimbusDefaults says it has a default [Pressed] background painter. What should I do, to see this when i click on the TableHeader? UPDATE 1 The NimbusStyle.getExtendedState returns the PRESSED on mouseDown correctly. But the NimbusStyle.getBackgroundPainter(SynthContext) returns null cause there is an null in the NimbusStyle.Values cache for the CacheKey "backgroundPainter$$instance" with this state. What is wrong there? UPDATE 2 My example shows a JTableHeader and a JScrollBar with an 'Pressed Behavior'. For the JScrollBar my

In my program I wanted to have a translucent white to transparent gradient on my JFrame to overlay a yellow background. This works fine and it needs to be a white to transparent because of how my settings for the program work for the user. However, when I take the program into college (JRE7 to my JRE6) the gradient goes white to blackish then transparent... It isn't so bad until you start to increase the opacity of the white colour... is there anyway I can fix this? here is the relevant code from the top of my JFrame code. public class DictionaryGUI extends JFrame { protected JPanel

I use Nimbus Look and Feel in a project. However, although every GUI JComponent have a Look and Feel of Nimbus, JFrame always have Windows Look and Feel. How can JFrame have Nimbus Look And Feel? Edit: Operating System : Windows XP Marek Sebera Try using this: JFrame.setDefaultLookAndFeelDecorated(true); //before creating JFrames For more info., see How to Set the Look and Feel in the tutorial. import javax.swing.*; class FrameLook { public static void showFrame(String plaf) { try { UIManager.setLookAndFeel(plaf); } catch(Exception e) { e.printStackTrace(); } JFrame f = new JFrame(plaf); f

Nimbus often looks great, but for certain color combinations the result is non-optimal. In my case, the background of a JPopupMenu does not fit, which is why I want to set it manually. I'm on Java 7 and, interestingly, Nimbus fully ignores the setting of some properties in the UIManager (like PopupMenu.background ). So my only option was to create a subclass of JPopupMenu that overrides paintComponent(...) . I know, that's nasty, but at least it worked. However, if you add a JMenu to another menu, it embeds it's own instance of JPopupMenu and I could not figure out how to replace it with my

一、静态数据和流数据 静态数据：为了支持决策分析而构建的数据仓库系统，其中存放的大量历史数据就是静态数据。 流数据：以大量、快速、时变的流形式持续到达的数据。（例如：实时产生的日志、用户实时交易信息） 流数据具有以下特点： (1)、数据快速持续到达，潜在大小也许是无穷无尽的。 (2)、数据来源众多，格式复杂。 (3)、数据量大，但是不十分关注存储，一旦经过处理，要么被丢弃，要么被归档存储(存储于数据仓库)。 (4)、注重数据的整体价值，不过分关注个别数据。 (5)、数据顺序颠倒，或者不完整，系统无法控制将要处理的新到达的数据元素的顺序。 在传统的数据处理流程中，总是先收集数据，然后将数据放到DB中。然后对DB中的数据进行处理。 流计算：为了实现数据的时效性，实时消费获取的数据。 二、批量计算和流计算 批量计算：充裕时间处理静态数据，如Hadoop。实时性要求不高。 流计算：实时获取来自不同数据源的海量数据，经过实时分析处理，获得有价值的信息(实时、多数据结构、海量)。 流计算秉承一个基本理念，即数据的价值随着时间的流逝而降低，如用户点击流。因此，当事件出现时就应该立即进行处理，而不是缓存起来进行批量处理。流数据数据格式复杂、来源众多、数据量巨大，不适合采用批量计算，必须采用实时计算，响应时间为秒级，实时性要求高。批量计算关注吞吐量，流计算关注实时性。 流计算的特点： 1、实时
