  • Events do not propagate from a child element?

    - by Legend
    I was playing around with the Swipe jQuery plugin on my iPod Touch and Android devices. The following works: <html> <head> <script type="text/javascript" src="lib/jquery/jquery-1.3.2.js"></script> <script type="text/javascript" src="lib/plugins/jquery.swipe.js"></script> <script type="text/javascript"> $(function() { $('body').swipe({ swipeLeft: function() { $('#container1').append("Swiped Left!"); }, swipeRight: function() { $('#container2').append("Swiped Right!");} }); }); </script> <style type="text/javascript"> body {width: 300px; height: 300px; background: #000;} </style> </head> <body> <div id="container1"> This is container one </div> <div id="container2"> This is container two </div> </body> </html> But if I have something like this: <html> <head> <script type="text/javascript" src="lib/jquery/jquery-1.3.2.js"></script> <script type="text/javascript" src="lib/plugins/jquery.swipe.js"></script> <script type="text/javascript"> $(function() { $('#wrapper').swipe({ swipeLeft: function() { $('#container1').append("Swiped Left!"); }, swipeRight: function() { $('#container2').append("Swiped Right!");} }); }); </script> <style type="text/javascript"> body {width: 300px; height: 300px; background: #000;} </style> </head> <body> <div id="wrapper"> <div id="container1"> This is container one </div> <div id="container2"> This is container two </div> </div> </body> </html> Notice the "wrapper" div around the containers. Now, when I swipe on the div element, I was expecting it to actually trigger the event. This works in iPod touch as expected but does not work on my Android device unless I randomly start swiping everywhere until I happen to swipe on that small wrapper div element itself. I am not sure how to explain this but hink of it as sending events to the wrapper div itself. Both use the WebKit engine. Can someone tell me if I am doing something wrong?

  • How can I convert and repair MPEG-TS (DVB-S captures) for better playback?

    - by SofaKng
    I have a lot of MPEG-TS video files (H.264 video with AC3 or MP3 in a .TS container) captured from a DVB-S capture card. When I play these videos it's much slower to seek in the video (ie. skip 30 seconds, etc) than with other files. I'm not sure if the problem is the H.264 encoding (reference frame count?) or the MPEG-TS container, or if the MPEG-TS file contains sync errors, etc. Does anybody have a good workflow for converting and repairing these files?

  • Django: How to handle imports in a reusable app

    - by facha
    everyone I'm just starting with django. It is not quite clear to me, how should I write an app I could reuse later. In every tutorial I read I see the same piece of code: view.py from project.app.models import MyModel So, if I move my apps to another project, I'll have to modify the "project.app.models" so that it looks like "project2.app.models" for every app I move. Is there a way to avoid that? Thanks in advance.

  • Why isn't my div scrolling horizontally when adding multiple images?

    - by George
    I have an outer div, and inside of that, I have an inner div which contains a list of images. When the images are wider than the outer div, I want to have it scroll horizontally, but instead, it just puts the image on the next line instead of expanding. If I add many rows, the div does scroll vertically, but horizontally, it doesn't do it. This happens on every browser I've tried - Firefox, Chrome, IE, and Safari. Here is the css: #grid-container { left:33px; position:relative; width:300px; } #grid { width:310px; height:400px; overflow:auto; margin-bottom: 15px; } #grid-container ul { width:305px; } #grid-container li { float:left; list-style-type:none; padding:5px 15px 5px 15px; height:88px; text-align:center; } .image-row { float:left; margin-left: 10px; } .grid-image { height:50px; margin-left:-20px; } Here is the html: <div id="grid-container"> <div id="grid"> <div id="row1" class="image-row"> <ul> <li> <img id="img1" class="grid-image" src="images/img1.jpg"> </li> <li> <img id="img2" class="grid-image" src="images/img2.jpg"> </li> <li> <img id="img3" class="grid-image" src="images/img3.jpg"> </li> <li> <img id="img4" class="grid-image" src="images/img4.jpg"> </li> </ul> </div> <div id="row1" class="image-row"> <ul> <li> <img id="img5" class="grid-image" src="images/img5.jpg"> </li> <li> <img id="img6" class="grid-image" src="images/img6.jpg"> </li> </ul> </div> </div> </div> The problem is img4 is showing on the second row (with img5 and img5 on the third row), even though it should on the first row and the grid div should scroll horizontally. It does scroll vertically. Can I force the div to expand? If I remove the width from the grid div, I do get the horizontal scroll bar, but the image is still on the second row.

  • Recommended migration strategy for C++ project in Visual Studio 6

    - by jacobsee
    For a large application written in C++ using Visual Studio 6, what is the best way to move into the modern era? I'd like to take an incremental approach where we slowly move portions of the code and write new features into C# for example and compile that into a library or dll that can be referenced from the legacy application. Is this possible and what is the best way to do it?

  • setting something disposed or invisible java

    - by OVERTONE
    this might be simple enough as just inserting the right method but i cant seem to get it right. i have a simple program with two buttons. each one changes the picture above them. but anytime i click the buttons i get some odd awt event queue error. i think its because im trying to add something to a frame after its already been made. package icnon; import javax.imageio.*; import javax.swing.*; import java.awt.*; import java.awt.event.*; public class FrameIconExample extends JFrame implements ActionListener { JLabel j; JPanel p, l, k; JButton picOne, picTwo; Container cPane; public FrameIconExample() { JButton picOne = new JButton("picOne"); JButton picTwo = new JButton("picTwo"); picOne.setName("picOne"); picTwo.setName("picTwo"); picOne.addActionListener(this); picTwo.addActionListener(this); JPanel p = new JPanel(new GridLayout(2, 1)); JPanel l = new JPanel(new FlowLayout()); JPanel k = new JPanel(new FlowLayout()); cPane = getContentPane(); j = new JLabel(new ImageIcon("../meet/src/images/beautiful-closeup-portrait-photography.jpg")); l.add(j); k.add(picOne); k.add(picTwo); p.add(l); p.add(k); add(p); } public static void main(String[] args) { FrameIconExample frame = new FrameIconExample(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(new Dimension(300, 800)); frame.setTitle("Frame Icon Example"); // Display the form frame.setVisible(true); } @Override public void actionPerformed(ActionEvent e) { JButton temp = (JButton) e.getSource(); String src = "../meet/src/images/Majken Kruse portrait - john.jpg"; //System.out.println(src + " " + temp.getName()); if(temp.getName().equalsIgnoreCase("picOne")) { src = "../meet/src/images/beautiful-closeup-portrait-photography.jpg"; System.out.println(src + " " + temp.getName()); Icon img; j = new JLabel(new ImageIcon(src)); l.add(j); System.out.println("1"); } if(temp.getName().equalsIgnoreCase("picTwo")) { src = "../icontest/images/Majken Kruse portrait - john.jpg"; System.out.println(src + " " + temp.getName()); Icon img; j = new JLabel(new ImageIcon(src)); l.add(j); System.out.println("2"); } } } its all just the one program so if you copy paste it into an editor you can see the stack trace. but the source of the image files wont be there. does anyone know how id do it? or where im goin wrong? stack trace: ../meet/src/images/beautiful-closeup-portrait-photography.jpg picOne Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at icnon.FrameIconExample.actionPerformed(FrameIconExample.java:68) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)

    Duplicate: Is there any form designer available for Google Android? I would like to move a CheckBox, so it displays in a different location than the top-left corner under Absolute Layout inside main.xml, for 'Android'. I'm using Eclipse to edit my views. How would I do this? On an iPhone they have a tool called Interface builder that allows you to move things in a WYIWYG fashion. Does Eclipse have similar functionality? Regards ShotSimon

  • CSS optimization - extra classes in dom or preprocessor-repetitive styling in css file?

    - by anna.mi
    I'm starting on a fairly large project and I'm considering the option of using LESS for pre-processing my css. the useful thing about LESS is that you can define a mixin that contains for example: .border-radius(@radius) { -webkit-border-radius: @radius; -moz-border-radius: @radius; -o-border-radius: @radius; -ms-border-radius: @radius; border-radius: @radius; } and then use it in a class declaration as .rounded-div { .border-radius(10px); } to get the outputted css as: .rounded-div { -webkit-border-radius: 10px; -moz-border-radius: 10px; -o-border-radius: 10px; -ms-border-radius: 10px; border-radius: 10px; } this is extremely useful in the case of browser prefixes. However this same concept could be used to encapsulate commonly-used css, for example: .column-container { overflow: hidden; display: block; width: 100%; } .column(@width) { float: left; width: @width; } and then use this mixin whenever i need columns in my design: .my-column-outer { .column-container(); background: red; } .my-column-inner { .column(50%); font-color: yellow; } (of course, using the preprocessor we could easily expand this to be much more useful, eg. pass the number of columns and the container width as variables and have LESS determine the width of each column depending on the number of columns and container width!) the problem with this is that when compliled, my final css file would have 100 such declarations, copy&pasted, making the file huge and bloated and repetitive. The alternative to this would be to use a grid system which has predefined classes for each column-layout option, eg .c-50 ( with a "float: left; width:50%;" definition ), .c-33, .c-25 to accomodate for a 2-column, 3-column and 4-column layout and then use these classes to my dom. i really mislike the idea of the extra classes, from experience it results to bloated dom (creating extra divs just to attach the grid classes to). Also the most basic tutorial for html/css would tell you that the dom should be separated from the styling - grid classes are styling related! to me, its the same as attaching a "border-radius-10" class to the .rounded-div example above! on the other hand, the large css file that would result from the repetitive code is also a disadvantage so i guess my question is, which one would you recommend? and which do you use? and, which solution is best for optimization? apart from the larger file size, has there even been any research on whether browser renders multiple classes faster than a large css file, or the other way round? tnx! i'd love to hear your opinion!

  • Should I bother with C++ or go straight to C#?

    - by Pat Riley
    I have been writing embedded C applications for almost 20 years. In the last few years I have written quite a few PC based GUI interfaces in Visual C so I could interface my embedded systems to a PC. Although my primary work will still be in deeply embedded C, I have finally decided to move my PC based tools into Ruby - (for quick scripting type stuff) and C++ or C# for GUI based interfaces and applications. Should I bother with C++ or just move straight to C#?

  • Can Camel Jetty proxy URL share the webapplication context

    - by user1750353
    I am struggling with Camel Jetty Proxy Routes. At times, the routes exhibits inconsistent behavior. My Proxy app deployed with context root "Proxy", however, if give that as the context path for my proxy URL I get service not found error. If change the Proxy to an arbitrary context such as "Dummy" then the route works. Is that how camel jetty component works? From Path: jetty:http://0.0.0.0:6080/Proxy/PurchaseOrder/?matchOnUriPrefix=true&disableStreamCache=true&traceEnabled=true To Path: jetty:http://localhost:7001/Provider/PurchaseOrder/?bridgeEndpoint=true&throwExceptionOnFailure=false Another issue i noticed with jetty is If deploy both Proxy and Provider on the same app container(same listening port), then the route completely stops working saying "Provider/PurchaseOrder/" service not found. The only way the routes work is, both routes have to run different ports and the from route shouldn't share the webcontext path. I have requirement that if required I should be a able run both Proxy and Provider on the same container. Any help appreciated. Thanks,

  • elisp: posn-at-point returns nil after goto-char. How to update the display before posn-at-point?

    - by Cheeso
    In emacs lisp, posn-at-point is documented as: posn-at-point is a built-in function in C source code. (posn-at-point &optional POS WINDOW) . Return position information for buffer POS in WINDOW. POS defaults to point in WINDOW; WINDOW defaults to the selected window. . Return nil if position is not visible in window. Otherwise, the return value is similar to that returned by event-start for a mouse click at the upper left corner of the glyph corresponding to the given buffer position: (WINDOW AREA-OR-POS (X . Y) TIMESTAMP OBJECT POS (COL . ROW) IMAGE (DX . DY) (WIDTH . HEIGHT)) The posn- functions access elements of such lists. ok, now I've got a function that looks something like this: (defun my-move-and-popup-menu () "move the point, then pop up a menu." (goto-char xxxx) (setq p (posn-at-point)) (my-popup-menu p ...) ) Basically, move the point, then retrieve the screen position at that point, and then popup a menu at that screen position. But I am finding that posn-at-point returns non-nil, only if the xxxx character position (the after position) is visible in the window, before the call to goto-char. It seems that the position is not actually updated until exit from the function. If goto-char goes a long way, more than one screenful, then the retrieved position is always nil, and my code doesn't know where to popup the menu. The reason I suggest that the position is not actually updated until exit from the function - when the menu successfully pops up, the cursor is clearly visible in its previous location while the popup menu is being displayed. When I dismiss the menu, the cursor moves to where I expected it to move, after the goto-char call. How can I get the position to be really updated, between goto-char and posn-at-point, so that posn-at-point will not return nil? In a Windows Forms application I would call Form.Update() or something similar to update the display in the middle of an event handler. What's the emacs version of that?

  • Windows 8 power-shell "update-help" is failing. Does anyone know how to fix it?

    - by Warren P
    Windows 8 includes PowerShell out of the box, but not the help. To get the help you run PowerShell as administrator and type "update-help". I get this error: > update-help update-help : Failed to update Help for the module(s) 'BitLocker, NetWNV' with UI culture(s) {en-US} : The value of the HelpInfoUri key in the module manifest must resolve to a container or root URL on a website where the help files are stored.

  • creating a full html file out of webloc in a batch mode

    - by Wordpress Newbie
    Hi, I've got over 400 bookmarks saved as .webloc files. I'd like to move them to the iPhone's goodReader app. goodReader cannot open webloc files. It can sork with pdf, html but not webloc. Do you know of a way or a program that would take a folder as its input, and convert every single .webloc file in it into a PDF version or a html version - so I can grab the converted files and move them onto iPhone. Thank you

  • Excel macro to change location of .cub files used by pivot tables? (to allow .xls files that depend

    - by Rory
    I often use Excel with pivot tables based on .cub files for OLAP-type analysis. This is great except when you want to move the xls and you realise internally it's got a non-relative reference to the location of the .cub file. How can we cope with this - ie make it convenient to move around xls files that depend on .cub files? The best answer I could come up with is writing a macro that updates the pivot tables' reference to the .cub file location....so I'll pop that in an answer.

  • How do I clone an OpenLDAP database

    I know this is more like a serverfault question than a stackoverflow question, but since serverfault isn't up yet, here I go: I'm supposed to move an application from one redhat server to another, and without very good knowledge of the internal workings of the application, how would I move the OpenLDAP database from the one machine to the other, with schemas and all. What files would I need to copy over? I believe the setup is pretty standard.
