  • Accordion table cell - How to dynamically expand/contract uitableviewcell?

    - by s.newave
    Hi, I am trying create an accordion type of uitableviewcell that, when the user selects the cell, it expands to display a detailed info view inline similar to how the digg app works. I initially tried replacing the current tablecell with a customcell in cellForRowAtIndex however the animation looks a bit choppy as you can see the cell being replaced and overall the effect doesnt work to well. If you look at the digg app and others who have done this it seems that they arent replacing the current cell but instead perhaps adding a subview to the cell? The original cell however doesnt seem to animate at all and only the new view accordions into the table. Does anyone have any ideas how to accomplish a similar effect?

  • Google maps z-index problem in IE

    - by Bas van de Lustgraaf
    I'm loading my google maps into div class="extra" style="display: none;" /. As soon as the AJAX request is complete, the map_canvas div is placed inside the hidden div and the hidden div will be vissible with the toggleDown jquery effect. In FF it's working perfect, but in IE the Google maps (map_canvas div) is already visible before the toggleDown effect is started. I think the z-index and the relative position of the map_canvas div wich is loaded into the hidden div will place the map_canvas div on top of the hidden div. What do i have to change to make sure the map_canvas div is not on top of the hidden div? While toggleDown in FF: http:// img169.imageshack.us/img169/9274/50485429.jpg While toggleDown in IE: http://img188.imageshack.us/img188/2110/93959677.jpg

  • for loop vs while loop

    - by Atul
    We can use for loop and while loop for same purpose. in what means they effect our code if I use for instead of while? same question arises between if-else and switch-case? how to decide what to use? for example which one you would prefer? This code: int main() { int n; cin>>n; for(int i=0;i<n;i++) { do_something(); } return 0; } Or this code: int main() { int n,i=0; cin>>n; while(i<n) { do_something(); i++; } return 0; } if using for or while loop does not effect the code by any means then may I know What was the need to make 2 solution for same problem?

  • DirectX equivalent of glBlendFunc(............)

    - by Jimmy Bouker
    I created a particle System in OpenGl that's working great. When I want to get a burning effect of a fire or a beam or something(Where the system kind of "glows" and fuses all the colors together) I use this method call with OpenGL. glBlendFunc(GL_SRC_ALPHA,GL_SRC_ALPHA) glBlendFunc(GL_DST_ALPHA,GL_ONE) I'm now trying to do the same thing using Direct3D Here is what I have tried: graphicsDevice->SetRenderState(D3DRS_ALPHABLENDENABLE, TRUE); graphicsDevice->SetRenderState(D3DRS_SRCBLEND, D3DBLEND_SRCALPHA); graphicsDevice->SetRenderState(D3DRS_DESTBLEND, D3DBLEND_ONE); but this has absolutely no effect at all on the look of my game! Anyone have a clue what could be the problem?

  • How to inflate a view in a determined position?

    - by Tivie
    I have an activity with an "Add" and a "Delete" button. The "Add Button" inflates a view, the "Delete Button" removes a selected View. When I inflate a view with the "Add Button", it is automatically drawn below any previously infalted view. I would like to give the user the possibility to move each inflated view up and down, so he could change the order they are show in screen (in a drag'n'drop kind of effect) +---------------------+ +---------------------+ | +-----------------+ | | +-----------------+ | | | View 1 | | | | View 2 | | | +-----------------+ | | +-----------------+ | | | --> | | | +-----------------+ | | +-----------------+ | | | View 2 | | | | View 1 | | | +-----------------+ | | +-----------------+ | +---------------------+ +---------------------+ Is it possible to specify the "position" in which each view is inflated? (for instance, below or above the currently selected view?) If not, what is the best way to accomplish the desired effect? (feel free to ask for any piece of code, if you think it might help)

  • Using vim, how do you quickly refresh a web page you're working on?

    - by aLostMonkey
    I've been using VIM for a few weeks now while messing with various web languages and I'm really enjoying it. I find it cumbersome having to tab or click into my browser and refresh the page to see the effect of a code change. It's even more annoying as I'm using Virtual Box and I tend to be working from PDF files on the host system so I have limited window space. Do you gurus have any fancy ways of doing this? I was wondering if it's possible to split the VIM workspace and have links/lynx in a window of its own or something to that effect?

  • css3 nth child question

    - by JCHASE11
    Hello. I am designing a 960px wide layout with an unordered list. Each list item is 240px wide, so 4 list items fit horizontally in a row. I have about 20 rows on the page.... I want every other list item to have a background of #ececec, so my css would be: ul li:nth-child(2n+2){ background-color:#ececec; } This works. The only problem is because there are 4 items in a row (an even #), the next row would be identical, thus rendering background colors on every 1st and 3rd list items in a row. This is not the effect I am looking to achieve. I want the background colors to alternate, creating a grid-like effect. What is the correct css to do so (think a checker board). Thanks!

  • How to format complex chained Linq statements for readibility?

    - by Joan Venge
    I have some code like this: var effects = xElement.Elements ( "Effects" ).Elements ( "Effect" ).Select ( e => new Effect ( ( EffectType ) Enum.Parse ( typeof ( EffectType ), ( string ) e.Elements ( "Type" ).FirstOrDefault ( ) ), e.Elements ( "Options" ).Any ( ) ? e.Elements ( "Options" ).Select ( o => ( object ) o.Elements ( "Option" ).Select ( n => n.Value ).First ( ) ) : null ) ) .ToList ( ); But currently this doesn't look as readable and I am not sure where I should add a new line and/or indent for readability. Any suggestions I could use to make consistent, readable linq blocks?

  • Why is the value of __name__ changing after assignment to sys.modules[__name__]?

    - by martineau
    While trying to do something similar to what's in the ActiveState recipe titled Constants in Python by Alex Martelli, I ran into an unexpected side-effect that assigning a class instance to an entry in sys.modules apparently has in Python 2.7 -- namely that doing so apparent changes the value of __name__ to None as illustrated in the following code fragment: class _test(object): pass import sys print '__name__: %r' % __name__ # __name__: '__main__' sys.modules[__name__] = _test() print '__name__: %r' % __name__ # __name__: None if __name__ == '__main__': # never executes... import test print "done" I'd like to understand why this is happening. I don't believe it was that way in Python 2.6 and earlier versions since I have some older code where apparently the if __name__ == '__main__': conditional worked as expected following the assignment (but no longer does). FWIW, I also noticed that the name _class is getting rebound from a class object to None, too, after the assignment. Also seems odd to me that they're being rebound to 'None' rather than disappearing altogether... Update: I'd like to add that any workarounds for achieving the effect of if __name__ == '__main__':, given what happens would be greatly appreciated. TIA!

  • Detect NativeDragDrop to Trash or RecycleBin

    - by colder
    I will let user remove item from List with a cool method. Drag an item in adobe air List control and then drop it to Trash(OSX) or Recycle Bin(Win). The trash accept move drag action only. So I think I must set dragMoveEnable=true. When I drag an item to Recycle Bin on Windows. It show accept effect(alpha mask) and Air remove that object from List's dataProvider. So I can find which one is disappear. But when I drag to Trash on MacOSX. It show effect too. But Air do nothing for List. Maybe this is a bug. How can I avoid it? Are there any way to detect where dropped by user?

  • Dynamically udpate canvasOverlay property of jQuery jqPlot

    - by You Kuper
    I want to dynamically udpate canvasOverlay property of jQuery jqPlot. This will provide the effect of a timeline in my jqPlot. This effect should be similar to the one shown in this jFiddle. However, instead of drawing points, I want to update canvasOverlay property every second: canvasOverlay: { show: true, objects: [ { rectangle: { xmax: new Date(), xminOffset: "0px", xmaxOffset: "0px", yminOffset: "0px", ymaxOffset: "0px", color: "rgba(0, 0, 0, 0.1)", showTooltip: true } }, ] } How can I do this? What are the functions I should use? UPDATE: My idea is to do something like this: canvasOverlay: { name: 'current', show: true, objects: [ { rectangle: { xmax: new Date(), xminOffset: "0px", xmaxOffset: "0px", yminOffset: "0px", ymaxOffset: "0px", color: "rgba(0, 0, 0, 0.1)", showTooltip: true } }, ] } /... var co = plot.plugins.canvasOverlay; var current = co.get('current'); current.options.objects.rectangle.xmax = new Date(); co.draw(plot);

  • "tail -f" alternate which doesn't scroll the terminal window

    - by Jagtesh Chadha
    I want to check a file at continuous intervals for contents which keep changing. "tail -f" doesn't suffice as the file doesn't grow in size. I could use a simple while loop in bash to the same effect: while [ 1 ]; do cat /proc/acpi/battery/BAT1/state ; sleep 10; done It works, although it has the unwanted effect of scrolling my terminal window. So now I'm wondering, is there a linux/shell command that would display the output of this file without scrolling the terminal?

  • Entity diagram with tables that have foreign keys that point to a non-PK column do not show relation

    - by Jason Coyne
    I have two tables parent and child. If I make a foreign key on child that points to the primary key of parent, and then make an entity diagram, the relationship is shown correctly. If I make the foreign key point to a different column, the relationship is not shown. I have tried adding indexes to the column, but it does not have an effect. The database is sqlite, but I am not sure if that has an effect since its all hidden behind ADO.net. How do I get the relationship to work correctly?

  • HTML to automatically hide text depending on scrolled size (like in Gmail)?

    - by Stephen Cagle
    Look at your Gmail inbox. You have 3 main columns contains the Sender contains "THE_EMAIL_SUBJECT - THE_EMAIL_BODY" the date the email was sent on I note that when you resize the window, the Gmail web client automatically resizes the displayed text in the second column. It basically just truncates the text so that it always can display the sent on date to the right, and the sender to the left. It is a pretty neat effect, and I would like to have that effect for myself. Does anyone know how to do this in HTML/CSS/JS?

  • How does the stream manipulators work?

    - by Narek
    It is well known that the user can define stream manipulators like this: ostream& tab(ostream & output) { return output<< '\t'; } And this can be used in main() like this: cout<<'a'<<tab<<'b'<<'c'<<endl; Please explain me how does this all work? If operator<< assumes as a second parameter a pointer to the function that takes and returns ostream &, then please explain my why it is necessary? What would be wrong if the function does not take and return ostream & but it was void instead of ostream &? Also it is interesting why “dec”, “hex” manipulators take effect until I don’t change between them, but user defined manipulators should be always used in order to take effect for each streaming?

  • Manipulate DOM before it is shown to the user?

    - by user246114
    Hi, I'm not too familiar with javascript, is there a way to manipulate the DOM before the page is displayed to the user? I'm using GWT which makes you create the page elements via javascript. This is kind of convenient, but it appears that all the javascript code is executed after the page is first shown to the user. This has the effect of showing the page as a blank white screen, then all the UI elements popping onto screen. The effect is really apparent when switching between pages. If I were using php or jsp, it looks like the page ui elements are already prerendered and the browser won't show a blank white screen before display. So is there any hook in javascript where we can manipulate the DOM before the browser clears out the contents of the last page shown? Thanks

  • Unwanted Retriggering of Textbox Events

    - by user348917
    This is one of those "seems obvious" as how to do, but came across interesting side effect in implementing. I'm trying to keep two text boxes syncronized when information is updated. In this example, I will be using txtStartDate and txtEndDate. If the txtStartDate is changed, then the txtEndDate should should be updated. Likewise, if the txtEndDate changes, I want the txtSartDate to be updated. The side effect I'm comming across is that when I set them up under the TextChanged event for both, the events seem to retrigger against each other indefinately (endless loop?). Am I using the wrong event? Is this a task for a delegate?

  • Are there actually lag times to remove an email address from "the system"? [closed]

    - by Alex Gosselin
    For example, you send an unsubscribe message to a legitimate company or a spam, they reply that they will remove you and it may take up to 72 hours to take effect. I find it hard to believe anything that simple could take more than 3/4 of a second to take effect system wide. Another example would be when you call the visa activation line, there is a "delay" of several minutes while they try to sell you some kind of insurance. Usually just as you get the point across that you don't want it they will tell you your card has been activated and let you go. Are these delays real?

  • style a navigation link when a particular div is shown

    - by Matt Meadows
    I have JQuery working to show a particular div when a certain link is clicked. I have managed to apply the effect I'm after with the main navigation bar through id'ing the body tag and using css to style when the id is found. However, i'd like to apply the same effect to the sub navigation when a certain div is present. How the main navigation is styled: HTML: <nav> <ul> <li id="nav-home"><a href="index.html">Home</a></li> <li id="nav-showreel"><a href="showreel.html">Showreel</a></li> <li id="nav-portfolio"><a href="portfolio.html">Portfolio</a></li> <li>Contact</li> </ul> </nav> CSS: body#home li#nav-home, body#portfolio li#nav-portfolio { background: url("Images/Nav_Underline.png") no-repeat; background-position: center bottom; color: white; } (Other links havent been added to styling as those pages are still in development) How the sub navigation is structured: <nav id="portfolioNav"> <ul> <li id="portfolio-compositing"><a id="compositingWork" href="#">Compositing</a></li> <li id="portfolio-animation"><a id="animationWork" href="#">Animation</a></li> <li id="portfolio-motionGfx"><a id="GFXWork" href="#">Motion Graphics</a></li> <li id="portfolio-3D"><a id="3DWork" href="#">3D</a></li> </ul> </nav> As you can see, its similar format to the main navigation, however i've tried the same approach and it doesn't work :( The Javascript that switches the divs on the navigation click: <script type="text/javascript"> $(document).ready(function() { $('#3DWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #Portfolio3D'); }); $('#GFXWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #motionGraphics'); }); $('#compositingWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #PortfolioCompositing'); }); $('#animationWork').click(function(){ $('#portfolioWork').load('portfolioContent.html #PortfolioAnimation'); }); }); </script> JSFiddle for full HTML & CSS : JSFiddle File The effect I'm After:

  • How animate stacking divs in javascript/css?

    - by Teiviere
    Say I have 2 divs with the same CSS class that are stacked on top of each other: div { width:100px; height: 100px; background: red; } How do I make it so that when I click a button at the top of the page, a new div is created from off the screen at the bottom and moves upwards stopping where the 2nd div is.. When the button is clicked again, a 4th div moves in from the bottom of the screen and stops where the 3rd div is... etc creating a "stacked" divs effect? I know about position:fixed and adjusting values for top, but I am not sure how to dynamically calculate where to stop the animation to achieve this effect.
