  • Components are not longer resizable after moving

    - by Junior Software Developer
    Hi guys My question relates to swing programming. I want to enlarge a component (component x) by removing it from its parent panel (component a) and adding it in one of component a's parent (component b). Before that, I call setVisible(false) on all components in b. After that I want to make this back by removing it from b and adding on a. After that all components are not longer resizable. Why that? An easy example: import java.awt.BorderLayout; import java.awt.Color; import java.awt.Component; import java.awt.Dimension; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTabbedPane; public class SwingTest { private static ViewPanel layer1; private static JFrame frame; private static JTabbedPane tabbedPane; private static ViewPanel root; public static void main(String[] args) { frame = new JFrame(); frame.setLayout(new BorderLayout()); frame.setMinimumSize(new Dimension(800, 600)); root = new ViewPanel(); root.setBackground(Color.blue); root.setPreferredSize(new Dimension(400, 600)); root.setLayout(new BorderLayout()); root.add(new JLabel("blue area")); layer1 = new ViewPanel(); layer1.setBackground(Color.red); layer1.setPreferredSize(new Dimension(400, 600)); layer1.setLayout(new BorderLayout()); tabbedPane = new JTabbedPane(); tabbedPane.add("A", new JLabel("A label")); tabbedPane.setPreferredSize(new Dimension(400, 600)); layer1.add(tabbedPane); root.add(layer1); frame.add(root, BorderLayout.NORTH); frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); frame.pack(); frame.setVisible(true); Thread t = new Thread() { @Override public void run() { try { Thread.sleep(8000); System.out.println("start"); for (Component c : root.getComponents()) { c.setVisible(false); } layer1.remove(tabbedPane); root.add(tabbedPane); Thread.sleep(8000); root.remove(tabbedPane); layer1.add(tabbedPane); for (Component c : root.getComponents()) { c.setVisible(true); c.repaint(); } } catch (InterruptedException e) { //... } } }; t.start(); } }

  • Multiple choice test GUI with serialization of Q&A

    - by Bobby
    I'm working on a project for school in Java programming. I need to design a GUI that will take in questions and answers and store them in a file. It should be able to contain an unlimited number of questions. We have covered binary I/O. How do I write the input they give to a file? How would I go about having them add multiple questions from this GUI? package multiplechoice; import java.awt.*; import javax.swing.*; public class MultipleChoice extends JFrame { public MultipleChoice() { /* * Setting Layout */ setLayout(new GridLayout(10,10)); /* * First Question */ add(new JLabel("What is the category of the question?: ")); JTextField category = new JTextField(); add(category); add(new JLabel("Please enter the question you wish to ask: ")); JTextField question = new JTextField(); add(question); add(new JLabel("Please enter the correct answer: ")); JTextField correctAnswer = new JTextField(); add(correctAnswer); add(new JLabel("Please enter a reccomended answer to display: ")); JTextField reccomendedAnswer = new JTextField(); add(reccomendedAnswer); add(new JLabel("Please enter a choice for multiple choice option " + "A")); JTextField A = new JTextField(); add(A); add(new JLabel("Please enter a choice for multiple choice option " + "B")); JTextField B = new JTextField(); add(B); add(new JLabel("Please enter a choice for multiple choice option " + "C")); JTextField C = new JTextField(); add(C); add(new JLabel("Please enter a choice for multiple choice option " + "D")); JTextField D = new JTextField(); add(D); add(new JButton("Compile Questions")); add(new JButton("Next Question")); } public static void main(String[] args) { /* * Creating JFrame to contain questions */ FinalProject frame = new FinalProject(); // FileOutputStream output = new FileOutputStream("Questions.dat"); JPanel panel = new JPanel(); // button.setLayout(); // frame.add(panel); panel.setSize(100,100); // button.setPreferredSize(new Dimension(100,100)); frame.setTitle("FinalProject"); frame.setSize(600, 400); frame.setLocationRelativeTo(null); // Center the frame frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } }

  • JList with JScrollPane and prototype cell value wraps element names (replaces with dots instead of s

    - by Tom
    I've got a Jlist inside a JScrollPane and I've set a prototype value so that it doesn't have to calculate the width for big lists, but just uses this default width. Now, the problem is that the Jlist is for some reason replacing the end of an element with dots (...) so that a horizontal scrollbar will never be shown. How do I disable with "wrapping"? So that long elements are not being replaced with dots if they are wider than the Jlist's width? I've reproduced the issue in a small example application. Please run it if you don't understand what I mean: import javax.swing.*; import java.awt.*; public class Test { //window private static final int windowWidth = 450; private static final int windowHeight = 500; //components private JFrame frame; private JList classesList; private DefaultListModel classesListModel; public Test() { load(); } private void load() { //create window frame = new JFrame("Test"); frame.setSize(windowWidth, windowHeight); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setUndecorated(true); frame.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG); //classes list classesListModel = new DefaultListModel(); classesList = new JList(classesListModel); classesList.setPrototypeCellValue("prototype value"); classesList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); classesList.setVisibleRowCount(20); JScrollPane scrollClasses = new JScrollPane(classesList, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED); for (int i = 0; i < 200; i++) { classesListModel.addElement("this is a long string, does not fit in width"); } //panel JPanel drawingArea = new JPanel(); drawingArea.setBackground(Color.white); drawingArea.add(scrollClasses); frame.add(drawingArea); //set visible frame.setVisible(true); } } Even if you force horizontal scrollbar, you still won't be able to scroll because the element is actually not wider than the width because of the dot (...) wrapping. Thanks in advance.

  • Queston about torrents

    - by c0mrade
    Why do my torrents go at rate 25/30 kb/s and my regular http downloads rate up to 300 kb/s .. is my ISP to blame for this, I meant torrents have like thousand seeders and again its very slow.How are they blocking torrent speed, can I bypass it? @gekkz Results : * There's no indication that your ISP rate limits all downloads at port 6881. In our test, a TCP download on a BitTorrent port achieved at least 392 Kbps while a TCP download on a non-BitTorrent port achieved at least 223 Kbps. You can find details here. * There's no indication that your ISP rate limits all uploads at port 6881.

  • Block Google requests to 16k using pf firewall

    - by atmosx
    I'd like to block access to Google search using PF after the threshold of 17500 requests (connection established) in 24h, from a host running FreeBSD 9. What I came up with, after reading pf-faq is this rule: pass out on $net proto tcp from any to 'www.google.com' port www flags S/SA keep state (max-src-conn 200, max-src-conn-rate 17500/86400) NOTE: 86400 are 24h in seconds. The rule should work, but PF is smart enough to know that www.google.com resolves in 5 different IPs. So my pfctl -sr output gives me this: pass out on vte0 inet proto tcp from any to 173.194.44.81 port = http flags S/SA keep state (source-track rule, max-src-conn 200, max-src-conn-rate 17500/86400, src.track 86400) pass out on vte0 inet proto tcp from any to 173.194.44.82 port = http flags S/SA keep state (source-track rule, max-src-conn 200, max-src-conn-rate 17500/86400, src.track 86400) pass out on vte0 inet proto tcp from any to 173.194.44.83 port = http flags S/SA keep state (source-track rule, max-src-conn 200, max-src-conn-rate 17500/86400, src.track 86400) pass out on vte0 inet proto tcp from any to 173.194.44.80 port = http flags S/SA keep state (source-track rule, max-src-conn 200, max-src-conn-rate 17500/86400, src.track 86400) pass out on vte0 inet proto tcp from any to 173.194.44.84 port = http flags S/SA keep state (source-track rule, max-src-conn 200, max-src-conn-rate 17500/86400, src.track 86400) PF creates 5 different rules, 1 for each IP that Google resolves. However I have the sense - without being 100% sure, I didn't had the chance to test it - that the number 17500/86400 applies for each IP. If that's the case - please confirm - then it's not what I want. In pf-faq there's another option called source-track-global: source-track This option enables the tracking of number of states created per source IP address. This option has two formats: + source-track rule - The maximum number of states created by this rule is limited by the rule's max-src-nodes and max-src-states options. Only state entries created by this particular rule count toward the rule's limits. + source-track global - The number of states created by all rules that use this option is limited. Each rule can specify different max-src-nodes and max-src-states options, however state entries created by any participating rule count towards each individual rule's limits. The total number of source IP addresses tracked globally can be controlled via the src-nodes runtime option. I tried to apply source-track-global in the above rule without success. How can I use this option in order to achieve my goal? Any thoughts or comments are more than welcome since I'm an amateur and don't fully understand PF yet. Thanks

  • How to prioritize openvpn traffic?

    - by aditsu
    I have an openvpn server, with one network interface. VPN traffic is extremely slow. I tried to do traffic control with this configuration (currently): qdisc del dev eth0 root qdisc add dev eth0 root handle 1: htb default 12 class add dev eth0 parent 1: classid 1:1 htb rate 900mbit #vpn class add dev eth0 parent 1:1 classid 1:10 htb rate 1500kbit ceil 3000kbit prio 1 #local net class add dev eth0 parent 1:1 classid 1:11 htb rate 10mbit ceil 900mbit prio 2 #other class add dev eth0 parent 1:1 classid 1:12 htb rate 500kbit ceil 1000kbit prio 2 filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 1194 0xffff flowid 1:10 filter add dev eth0 protocol ip parent 1:0 prio 2 u32 match ip dst 192.168.10.0/24 flowid 1:11 qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10 qdisc add dev eth0 parent 1:11 handle 11: sfq perturb 10 qdisc add dev eth0 parent 1:12 handle 12: sfq perturb 10 But it's still extremely slow. I have an imaps connection that keeps transferring data continuously (I successfully limited the rate) but with openvpn I can't seem to get more than about 100kbit/s The internet connection speed is about 3mbit/s (symmetric) What could be the problem? Does the sport filter work for udp?

  • iis7 bandwith throttling for downloads via iis media services?

    - by MikeJ
    I am looking after a sever that is managing the downloads of software updates released by the company where I work. The throttle in IIS7 seems to limit the total rate and not the rate each individual download gets. I was thnking on installing media services, adding .zip as a type and then throttling the individual connection rate based on what I read. Is this how this sort of thing is done with IIS7?

  • Can't communicate between lan ports on openwrt router

    - by ScaryAardvark
    I've got a WBMR-HP-G300H Buffalo Airstation router on which I've installed the lates OpenWRT software. All is working well (ADSL, WIFI etc) except for one niggle. I can't communicate between lan ports. i.e. if I have one computer connected on lan port 1 and I try to ping another computer on lan port 2 then I get "destination unreachable". I can ping both computers from the router itself and can also ping each computer from a seperate laptop connected wirelessly. All computers are in the same subnet range (10.0.0.?/24). I suspect that I may need to configure a vlan on the switch but everytime I try and do this with various google'ed configuration I keep freezing out all lan-ports and I have to revert back using a wirelessly connected laptop. Here's my /etc/config/network: config interface 'loopback' option ifname 'lo' option proto 'static' option ipaddr '127.0.0.1' option netmask '255.0.0.0' config interface 'lan' option type 'bridge' option proto 'static' option netmask '255.255.255.0' option ipaddr '10.0.0.1' option _orig_ifname 'eth0 wlan0' option _orig_bridge 'true' option ifname 'eth0' config adsl-device 'adsl' option fwannex 'a' option annex 'a2p' config interface 'wan' option _orig_ifname 'nas0' option _orig_bridge 'false' option proto 'pppoa' option encaps 'vc' option atmdev '0' option vci '38' option vpi '0' option username '?????????????' option password '??????????????'

  • FFMPEG dropping frames while encoding JPEG sequence at color change

    - by Matt
    I'm trying to put together a slide show using imagemagick and FFMPEG. I use imagemagick to expand a single photo into 30fps video (imagemagick also handles things like putting some text captions on the frames along the way). When I go to let ffmpeg digest it into a video it clips along nicely on the color parts of the video, but when it gets to a black and white section it reports "frame= 2030 fps=102 q=32766.0 Lsize= 5203kB time=00:01:07.60 bitrate= 630.5kbits/s dup=0 drop=703" and drops every frame of video until it hits something with color. As you can imagine this results in entire photos being removed from the slideshow. Here is my latest dump... ffmpeg -y -r 30 -i "teststream/%06d.jpg" -c:v libx264 -r 30 newffmpeg.mp4 ffmpeg version git-2012-12-10-c3bb333 Copyright (c) 2000-2012 the FFmpeg developers built on Dec 10 2012 22:02:04 with gcc 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3) configuration: --enable-gpl --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-librtmp --enable-libtheora --enable-libvorbis --enable-libx264 --enable-nonfree --enable-version3 libavutil 52. 12.100 / 52. 12.100 libavcodec 54. 79.101 / 54. 79.101 libavformat 54. 49.100 / 54. 49.100 libavdevice 54. 3.102 / 54. 3.102 libavfilter 3. 26.101 / 3. 26.101 libswscale 2. 1.103 / 2. 1.103 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 2.100 / 52. 2.100 Input #0, image2, from 'teststream/%06d.jpg': Duration: 00:12:02.80, start: 0.000000, bitrate: N/A Stream #0:0: Video: mjpeg, yuvj444p, 720x480 [SAR 72:72 DAR 3:2], 25 fps, 25 tbr, 25 tbn, 25 tbc [libx264 @ 0x3450140] using SAR=1/1 [libx264 @ 0x3450140] using cpu capabilities: MMX2 SSE2Fast SSSE3 FastShuffle SSE4.2 [libx264 @ 0x3450140] profile High, level 3.0 [libx264 @ 0x3450140] 264 - core 129 r2 1cffe9f - H.264/MPEG-4 AVC codec - Copyleft 2003-2012 - http://www.videolan.org/x264.html - options: cabac=1 ref=3 deblock=1:0:0 analyse=0x3:0x113 me=hex subme=7 psy=1 psy_rd=1.00:0.00 mixed_ref=1 me_range=16 chroma_me=1 trellis=1 8x8dct=1 cqm=0 deadzone=21,11 fast_pskip=1 chroma_qp_offset=-2 threads=12 lookahead_threads=2 sliced_threads=0 nr=0 decimate=1 interlaced=0 bluray_compat=0 constrained_intra=0 bframes=3 b_pyramid=2 b_adapt=1 b_bias=0 direct=1 weightb=1 open_gop=0 weightp=2 keyint=250 keyint_min=25 scenecut=40 intra_refresh=0 rc_lookahead=40 rc=crf mbtree=1 crf=23.0 qcomp=0.60 qpmin=0 qpmax=69 qpstep=4 ip_ratio=1.40 aq=1:1.00 Output #0, mp4, to 'newffmpeg.mp4': Metadata: encoder : Lavf54.49.100 Stream #0:0: Video: h264 ([33][0][0][0] / 0x0021), yuvj420p, 720x480 [SAR 1:1 DAR 3:2], q=-1--1, 15360 tbn, 30 tbc Stream mapping: Stream #0:0 - #0:0 (mjpeg - libx264) Press [q] to stop, [?] for help Input stream #0:0 frame changed from size:720x480 fmt:yuvj444p to size:720x480 fmt:yuvj422p Input stream #0:0 frame changed from size:720x480 fmt:yuvj422p to size:720x480 fmt:yuvj444pp=584 frame= 2030 fps=102 q=32766.0 Lsize= 5203kB time=00:01:07.60 bitrate= 630.5kbits/s dup=0 drop=703 video:5179kB audio:0kB subtitle:0 global headers:0kB muxing overhead 0.472425% [libx264 @ 0x3450140] frame I:9 Avg QP:20.10 size: 33933 [libx264 @ 0x3450140] frame P:636 Avg QP:24.12 size: 6737 [libx264 @ 0x3450140] frame B:1385 Avg QP:27.04 size: 514 [libx264 @ 0x3450140] consecutive B-frames: 2.5% 15.2% 13.2% 69.2% [libx264 @ 0x3450140] mb I I16..4: 8.3% 80.3% 11.5% [libx264 @ 0x3450140] mb P I16..4: 1.5% 2.5% 0.2% P16..4: 41.7% 18.0% 10.3% 0.0% 0.0% skip:25.9% [libx264 @ 0x3450140] mb B I16..4: 0.0% 0.0% 0.0% B16..8: 26.6% 0.6% 0.1% direct: 0.2% skip:72.3% L0:35.0% L1:60.3% BI: 4.7% [libx264 @ 0x3450140] 8x8 transform intra:64.1% inter:75.1% [libx264 @ 0x3450140] coded y,uvDC,uvAC intra: 51.6% 78.0% 43.7% inter: 10.6% 14.9% 2.1% [libx264 @ 0x3450140] i16 v,h,dc,p: 29% 19% 6% 46% [libx264 @ 0x3450140] i8 v,h,dc,ddl,ddr,vr,hd,vl,hu: 23% 15% 17% 5% 9% 10% 7% 8% 6% [libx264 @ 0x3450140] i4 v,h,dc,ddl,ddr,vr,hd,vl,hu: 31% 18% 11% 5% 9% 10% 6% 6% 4% [libx264 @ 0x3450140] i8c dc,h,v,p: 46% 18% 24% 12% [libx264 @ 0x3450140] Weighted P-Frames: Y:20.1% UV:18.7% [libx264 @ 0x3450140] ref P L0: 59.2% 23.2% 13.1% 4.3% 0.2% [libx264 @ 0x3450140] ref B L0: 88.7% 8.3% 3.0% [libx264 @ 0x3450140] ref B L1: 95.0% 5.0% [libx264 @ 0x3450140] kb/s:626.88 Received signal 2: terminating.

  • RAID 6 that can read with least 1000 Mbit/s?

    - by Diblo Dk
    I purchased a Dell PERC 6/i which I expected to be able to read with 1000 Mbps. There is not much to do now, but there are some things I wanted knowledge about for another time. I have configured it with four 2 TByte drives and RAID 6. It have 256 MByt ram and transfer rate of 300 Mbps. The benchmark test showed: Min read rate: 136.3 Mbps Max read rate: 329,6 Mbps Avg read rate: 242,2 Mbps What could I had done to get at least 1000 Mbps? Is it normal for internal and external RAID controllers to have a lower transfer rate eg. 300 Mbps? (I did not noticed at the time that it was not 3 Gbps) How would a RAID 10 had performed compared to RAID 6 or 5? Would it have been better to use software RAID (Linux) with the internal 3 Gbps SATA controller? UPDATE: The drives is SATA III 6 Gbps. http://www.seagate.com/files/staticfiles/docs/pdf/datasheet/disc/desktop-hdd-data-sheet-ds1770-1-1212us.pdf (2TB)

  • Why does HDTune report better performing drives 2 months after installing them?

    - by Rolnik
    OK, so this is really weird. I ran HDTune on a newly set-up home-built computer and got the following readings from my drives in mid-November. SSD 154 MB/s RAID1 87 RAID0 198 (software installs) RAID0 98 Swap drive Today, in January, I run HDTune (same version) and get these results, in MB/s: SSD 186 RAID1 98 RAID0 241 RAID0 98 (Swap drive) Here are more details that HDTune reports on the SSD drive: HD Tune: OCZ-VERTEX Benchmark Blockquote Transfer Rate Minimum : 135.4 MB/sec Transfer Rate Maximum : 219.4 MB/sec Transfer Rate Average : 185.7 MB/sec Access Time : 0.1 ms Burst Rate : 187.3 MB/sec CPU Usage : -1.0% To get to my question: Why are my hard drives improving in performance? Most of my logical drives are in some form of RAID, except for the SSD. Will this performance ever deteriorate? Note, none of my drives are a hybrid drive that uses some form of SSD to enhance the write/reads on actual platters.

  • SMART Status Data Interpretation - Disk Utility

    - by Mah
    Last week my external harddisk (Seagate Barracuda 1.5TB in a custom enclosure) showed signs of failure (Disk Utility SMART Pre-failure status - several bad sectors) and I decided to change it. I bought a new HDD (Seagate Barracuda 2TB) and connected it to my Ubuntu box with a SATA to USB cable that could not report SMART status. I copied all the contents of the old HDD to the new HDD (one partition with rsync, the other with parted cp) and then gently replaced the old HDD with the new one inside my aluminum enclosure. For obscure reasons after reconnecting the new HDD through the old enclosure, the Linux box could not detect my partitions. I recovered the partitions with testdisk and restarted the computer. After the restart I checked the SMART status of the new HDD an I get this: Read Error Rate --------------- Normalized 108 Worst 99 Threshold 6 Value 16737944 I got a high value on the Seek Error Rate as well. Wondering why this happens I copied 2 GB directory from one partition to the other and rechecked the SMART status (5 minutes later). This time I got the following: Read Error Rate --------------- Normalized 109 Worst 99 Threshold 6 Value 24792504 As you see there has been an increase in the error rate. I am unable to interpret these numbers. Is my new hard disk already dying? What are the acceptable values in these fields for Seagate hard disks? Then why the assessment is still good? While I could get temperature and airflow temperature data from my old HDD, I can not fetch them for the new one. I noticed that my old hdd had got really hot sometimes. Is it possible that the enclosure is killing the harddisks due to high temperature?... Thanks

  • How can I improve the "smoothness" of a 2D side-scrolling iPhone game?

    - by MrDatabase
    I'm working on a relatively simple 2D side-scrolling iPhone game. The controls are tilt-based. I use OpenGL ES 1.1 for the graphics. The game state is updated at a rate of 30 Hz... And the drawing is updated at a rate of 30 fps (via NSTimer). The smoothness of the drawing is ok... But not quite as smooth as a game like iFighter. What can I do to improve the smoothness of the game? Here are the potential issues I've briefly considered: I'm varying the opacity of up to 15 "small" (20x20 pixels) textures at a time... Apparently varying the opacity in this manner can degrade drawing performance I'm rendering at only 30 fps (via NSTimer)... Perhaps 2D games like iFighter are rendered at a higher frame rate? Perhaps the game state could be updated at a faster rate? Note the acceleration vales are updated at 100 Hz... So I could potentially update part of the game state at 100 hz All of my textures are PNG24... Perhaps PNG8 would help (due to smaller size etc)

  • Trouble with speed and vectors

    - by Eegabooga
    I'm working on adding bullets to my game. Right now I can shoot bullets in the direction that I would like from a ship by getting the ship's angle: int speed = 5; int dx = -(cos(degreesToRadians(ship.angle)) * speed); // rate of change in the x direction int dy = -(sin(degreesToRadians(ship.angle)) * speed); // rate of change in the y direction bulletPosition.addX(dx); // addX(dx) is simply bulletPosition.x += dx bulletPosition.addY(dy); The ship is pretty much the exact same thing, except I use the += operator: int dx += -(cos(degreesToRadians(angle)) * 0.15) int dy += -(sin(degreesToRadians(angle)) * 0.15); shipPosition.addX(dx); shipPosition.addY(dy); I would like to be able to add the ship's velocity to the bullet's velocity, but I'm a little confused as to how should get the speed from the ship's vector. I thought that adding the ship's dx to the bullet's dx like int dx = -(cos(degreesToRadians(ship.angle)) * speed * dx) would work because I'm adding the rate of change of the ship to the rate of change of the bullet, but that doesn't work. So here's the final question: How can I get the speed of my ship and apply it to my bullet's speed? Thanks in advance for all help :)
