  • Java - Layering issues with Lists and Graphics2D

    - by Mirrorcrazy
    So I have a DisplayPanel class that extends JPanel and that also paints my numerous images for my program using Graphics2D. In order to be able to easily customly use this I set it up so that every time the panel is repainted it uses a List, that I can add to or remove from as the program processes. My problem is with layering. I've run into an issue where the List must have reached its resizing point (or something whacky like that) and so the images i want to display end up beneath all of the other images already on the screen. I've come to the community for an answer because I have faith you will provide a good one. DisplayPanel: package earthworm; import java.awt.Graphics; import java.awt.Graphics2D; import java.util.ArrayList; import java.util.List; import javax.swing.JPanel; public class DisplayPanel extends JPanel { private List<ImageMap> images = new ArrayList(); public DisplayPanel() { setSize(800, 640); refresh(); } public void refresh() { revalidate(); repaint(); } @Override public void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g; g2d.clearRect(0, 0, 800, 640); for(int i = 0; i < images.size(); i++) g2d.drawImage( images.get(i).getImage(), images.get(i).getX(), images.get(i).getY(), null); } public void paintImage(ImageMap[] images, ImageMap[] clearImages, boolean clear) { if(clear) this.images.clear(); else if(clearImages!=null) for(int i = 0; i < clearImages.length; i++) this.images.remove(clearImages[i]); if(images!=null) for(int i = 0; i<images.length; i++) this.images.add(images[i]); refresh(); } }

  • How do i convert from milliseconds to seconds units to be shown in a Label?

    - by Doron Muzar
    I have this code: private void Form1_MouseWheel(object sender, MouseEventArgs e) { if (leave == true) { if (e.Delta > 0) { if (timer1.Interval < 5000) { timer1.Interval += 1000; label2.Text = (timer1.Interval/1000).ToString(); } } else { if (timer1.Interval == 1000) { timer1.Interval -= 100; label2.Text = (timer1.Interval / 1000).ToString(); } } } } The original timer1 interval in the designer is set to 1000 milliseconds. In the mouse wheel event i did that it will show in the label2 the untis in seconds. And indeed when i move the mouse wheel up its slowing the timer and show it in seconds 1 2 3 4 5 The problem is with the second part i wanted that when its getting to 1 second or 1000 milliseconds if i will keep wheel it down it will show the units in 100 and change the timer1.interval in 100 units. So in label2 if it was on 1 second so now i will see 900 800 700 600 500 un till 100. And also the timer1 interval should be change to 900 milliseconds 800 700 600 untill 100. When its get to 100 just stop there dont keep getting under 100. The problem is with this part: if (timer1.Interval == 1000) { timer1.Interval -= 100; label2.Text = (timer1.Interval / 1000).ToString(); } Its not working at all. EDIT** My code now: if (leave == true) { if (e.Delta > 0) { if (timer1.Interval < 5000) { timer1.Interval += 1000; label2.Text = (timer1.Interval / 1000).ToString(); } } else { if (timer1.Interval > 1000) { timer1.Interval -= 1000; label2.Text = (timer1.Interval / 1000).ToString(); } else if (timer1.Interval <= 1000 && timer1.Interval > 100) { timer1.Interval -= 100; label2.Text = (timer1.Interval / (double)1000).ToString(); } } } But now if i was at 5 seconds(5000 milliseconds) now i move the wheel back down its counting 5 4 3 2 1 0 and stop on 0 It dosent show under 1 ...0.9 0.8 0.7 as it did before.

  • Should I worry about running out of HierarchyIDs?

    - by Bruno Martinez
    When you ask for a new HierarchyID between two others, the result gets progressively longer. For example, between 2/5.6 and 2/5.7 there's only 2/5.6.1 and other 4 component paths. The HierarchyID data type is limited to 800 some bytes, so you can't repeat this forever. Then again, integer types are also limited, but it isn't a problem in practice. Should I periodically defragment my table so that height doesn't grow unbounded?

  • File size in Python server

    - by Anna
    We have server on Python and client + web service on Ruby. That works only if file from URL is less than 800 k. It seems like "socket.puts data" in a client works, but "output = socket.gets" - not. I think problem is in a Python part. For big files tests run "Connection reset by peer". Is it buffer size variable by default somewhere in a Python?

  • How do I refer to an instance from inside it's own code in Adobe Flash.

    - by matt1024
    In Adobe Flash, I have a movie clip that is added to the stage when the keyboard is pressed. I want it to travel across the screen and disappear once it reaches the edge of the stage. At the moment I use this but the image appears and then stops. Here is my code: addEventListener(Event.ADDED_TO_STAGE,runtime); var c = 0 function runtime(){ while(this.x<800){ this.x += 12; } removeChild(this); } Thanks

  • Canvas scalable arc position

    - by Amay
    http://jsfiddle.net/cs5Sg/11/ I want to do the scalable canvas. I created two circles (arcs) and one line, when you click on circle and move it, the line will follow and change position. The problem is when I added code for resize: var canvas = document.getElementById('myCanvas'), context = canvas.getContext('2d'), radius = 12, p = null, point = { p1: { x:100, y:250 }, p2: { x:400, y:100 } }, moving = false; window.addEventListener("resize", OnResizeCalled, false); function OnResizeCalled() { var gameWidth = window.innerWidth; var gameHeight = window.innerHeight; var scaleToFitX = gameWidth / 800; var scaleToFitY = gameHeight / 480; var currentScreenRatio = gameWidth / gameHeight; var optimalRatio = Math.min(scaleToFitX, scaleToFitY); if (currentScreenRatio >= 1.77 && currentScreenRatio <= 1.79) { canvas.style.width = gameWidth + "px"; canvas.style.height = gameHeight + "px"; } else { canvas.style.width = 800 * optimalRatio + "px"; canvas.style.height = 480 * optimalRatio + "px"; } } function init() { return setInterval(draw, 10); } canvas.addEventListener('mousedown', function(e) { for (p in point) { var mouseX = e.clientX - 1, mouseY = e.clientY - 1, distance = Math.sqrt(Math.pow(mouseX - point[p].x, 2) + Math.pow(mouseY - point[p].y, 2)); if (distance <= radius) { moving = p; break; } } }); canvas.addEventListener('mouseup', function(e) { moving = false; }); canvas.addEventListener('mousemove', function(e) { if(moving) { point[moving].x = e.clientX - 1; point[moving].y = e.clientY - 1; } }); function draw() { context.clearRect(0, 0, canvas.width, canvas.height); context.beginPath(); context.moveTo(point.p1.x,point.p1.y); context.lineTo(point.p2.x,point.p2.y); context.closePath(); context.fillStyle = '#8ED6FF'; context.fill(); context.stroke(); for (p in point) { context.beginPath(); context.arc(point[p].x,point[p].y,radius,0,2*Math.PI); context.fillStyle = 'red'; context.fill(); context.stroke(); } context.closePath(); } init(); The canvas is scalable, but the problem is with the points (circles). When you change the window size, they still have the same position on the canvas area, but the distance change (so the click option fails). How to fix that?

  • HTML table print large column

    - by Emma
    Windows XP, IE 7 If the data in one of the column in table is more than say 800 bytes, it seems to print partial pages. Previews also appears same (span into multiple partial pages). What is the best way so that large number of rows with wide coulumns (fixed width) are printed properly without giving blank or partial page. Used table with thead and colgroup with width in 14%.

    Hello, I'm trying to get the dojo tree widget working. It works with a small json object, but when i try it with a large json object it goes wrong. There is no error, just the root node.

  • Is the W3 standard a major factor when google decides SERP position?

    - by Camran
    I have a dynamic php website which index only has around 800 errors according to the w3 validator online. I have tried checking major websites like ebay, stackoverflow and others also, all with around 400 errors. So my first thought is, what good is that validator when it always displays errors? Secondly, will the errors affect my SERP ranking? ie, will me fixing these errors as good as I can increase my Google search position? Thanks

  • I want to add ranges of rates for which I have a particular %

    - by happy
    My problem is I should add rates without overlapping and if a range of rates is missed while adding a new range I should display a message saying the range is missed. Example: 200 300 ----- 3% 300 400 ------5% and if I am adding new range, say 600 800 ------10% I should get a message saying the ranges 401 to 599 is missing.

I also need to be able to add more than just these two classes to my Jframe.

  • NVIDIA x server - "sudo nvidia config" does not generate a working 'xorg.config'

    - by Mike
    I am over 18 hours deep on this challenge. I got to this point and am stuck. very stuck. Maybe you can figure it out? Ubuntu Version 12.04 LTS with all the updates installed. Problem: The default settings in "etc/X11/xorg.conf" that are generated by the "nvidia-xconfig" tool, do not allow the NVIDIA x server to connect to the driver in my "System Settings Additional Driver window". (that's how I understand it. Lots of information below). Symptoms of Problem "System Settings Additional Driver" window has drivers, but the nvidia x server cannot connect/utilize any of the 4 drivers. the drivers are activated, but not in use. When I go to "System Tools Administration NVIDIA x server settings" I get an error that basically tells me to create a default file to initialize the NVIDIA X server (screen shot below). This is the messages the terminal gives after running a "sudo nvidia-xconfig" command for the first time. It seems that the generated file by the tool i just ran is generating a bad/unusable file: If I run the "sudo nvidia-xconfig" command again, I wont get an error the second time. However when I reboot, the default file that is generated (etc/X11/xorg.conf) simply puts the screen resolution at 800 x 600 (or something big like that). When I try to go to NVIDIA x server settings I am greeted with the same screen as the screen shot as in symptom 2 (no option to change the resolution). If I try to go to "system settings display" there are no other resolutions to choose from. At this point I must delete the newly minted "xorg.conf" and reinstate the original in its place. Here are the contents of the "xorg.conf" that is generated first (the one missing required information): # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 304.88 (buildmeister@swio-display-x86-rhel47-06) Wed Mar 27 15:32:58 PDT 2013 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 28.0 - 33.0 VertRefresh 43.0 - 72.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Depth 24 EndSubSection EndSection Hardware: I ran the "lspci|grep VGA". There results are: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [Quadro 1000M] (rev a1) More Hardware info: Ram: 16GB CPU: Intel Core i7-2720QM @2.2GHz * 8 Other: 64 bit. This is a triple boot computer and not a VM. Attempts With Not Success on My End: 1) Tried to append the "xorg.conf" with what I perceive is missing information and obviously it didn't fly. 2) All the other stuff I tried got me to this point. 3) See if this link is helpful to you (I barely get it, but i get enough knowing that a smarter person might find this useful): http://manpages.ubuntu.com/manpages/lucid/man1/nvidia-xconfig.1.html 4) I am completely new to Linux (40 hours over past week), but not to programming. However I am very serious about changing over to Linux. When you respond (I hope someone responds...) please respond in a way that a person new to Linux can understand. 5) By the way, the reason I am in this mess is because I MUST have a second monitor running from my laptop, and "System Settings Display" doesn't recognize my second display. I know it is possible to make the second display work in my system, because when I boot from the install CD, I perform work on the native laptop monitor, but the second monitor shows a purple screen with Ubuntu in the middle, so I know the VGA port is sending a signal out. If this is too much for you to tackle please suggest an alternative method to get a second display. I don't want to go to windows but I cannot have a single display. I am really fudged here. I hope some smart person can help. Thanks in advance. Mike. **********************EDIT #1********************** More Details About Graphics Card I was asked "which brand of nvidia-card do you have exactly?" Here is what I did to provide more info (maybe relevant, maybe not, but here is everything): 1) Took my Lenovo W520 right apart to see if there is an identifier on the actual card. However I realized that if I get deep enough to take a look, the laptop "won't like it". so I put it back together. Figuring out the card this way is not an option for me right now. 2) (My computer is triple boot) I logged into Win7 and ran 'dxdiag' command. here is the screen shot: 3) I tried to look on the lenovo website for more details... but no luck. I took a look at my receipts and here is info form receipt: System Unit: W520 NVIDIA Quadro 1000M 2GB 4) In win7 I went to the NVIDIA website and used the option to have my card 'scanned' by a Java applet to determine the latest update for my card. I tried the same with Ubuntu but I can't get the applet to run. Here is the recommended driver from from the NVIDIA Applet for my card for Win7 (I hope this shines some light on the specifics of the card): Quadro/NVS/Tesla/GRID Desktop Driver Release R319 Version: 320.00 WHQL Release Date: 3.5.2013 5) Also I went on the NVIDIA driver search and looked through every possible combination of product type + product series + product to find all the combinations that yield a 1000M card. My card is: Product Type: Quadro Product Series: Quadro Series (Notebooks) Product: 1000M ***********************EDIT #2******************* Additional Symptoms Another question that generated more symptoms I previously didn't mention was: "After generating xorg.conf by nvidia-xconfig, go to additional drivers, do you see nvidia-304?" 1) I took a screen shot of the "additional drivers" right after generating xorg.conf by nvidia-xconfig. Here it is: 2) Then I did a reboot. Now Ubuntu is 600 x 800 resolution. When I logged in after the computer came up I got an error (which I always get after generating xorg.conf by nvidia-xconfig and rebooting) 3) To finally answer the question - No. There is no "NVIDIA-304" driver. Screen shot of additional drivers after generating xorg.conf by nvidia-xconfig and rebooting : At this point I revert to the original xorg.conf and delete the xorg.conf generated by Nvidia.

  • C# 2D Camera Max Zoom

    - by Craig
    I have a simple ship sprite moving around the screen along with a 2D Camera. I have zooming in and out working, however when I zoom out it goes past the world bounds and has the cornflower blue background showing.

  • Asterisk - Trying to use call files to create a conference call between two dynamic numbers

    - by Hank
    I'm trying to setup an Asterisk system that will allow me to create a conference call between two dynamic numbers. It seems I can use 'call files' to make Asterisk initiate the call without needing an incoming call - http://www.voip-info.org/tiki-index.php?page=Asterisk+auto-dial+out This example seems to be what I'd need: Channel: SIP/mytrunk/12345678 MaxRetries: 2 RetryTime: 60 WaitTime: 30 Context: callme Extension: 800 Priority: 2 I can generate this file with some scripting language and then place it into the Asterisk Call File folder. The problem I'm having is: How do I call out to two numbers and join them in a conference call? The MeetMe plugin/extension seems to be what I need in terms of conference calling, I'm just unsure as to how I'd use the two together and join them. Also, is it possible to have multiple 2-person conference calls at the same time? Is setting this up as simple as setting aside X amount of 'channels' in the meetme.conf?

  • Is RAID 0 or JBOD better for home media server?

    - by Donald Hughes
    I have an external two-bay drive enclosure (the OWC Mercury Elite-AL Pro) connected to a Mac Mini (my home media server) over FireWire 800. I'm streaming media to other computers in the house over wired gigabit. I have two 1.5 TB drives that I'm using independently right now. The media is on one, and I'm mirroring the files to the other drive at night as a backup. But as I approach filling up the drive I'm wanting to span those two drives together to give me a total of about 3 TB, and then buy another drive for backups. The external enclosure supports both RAID 0 and JBOD, but I'm not clear on which would be better in this situation. Would RAID 0 provide any performance improvements over JBOD for streaming video (possibly several streams at once? How does each affect the MTBF of the drives? In general, should I choose RAID 0, JBOD, or keep them independent?
