  • CSS:Hover's problem with text that is hidden because of overflow:hidden ?

    - by Michael Harringon
    In my application i have lots of divs containing text. All divs have overflow set to hidden so that the user does not see the text if the container is not large enough to contain the writing. If the user wants to see the hidden text they are supposed to mouse over the "box". The box then expands and shows the text. Sounds simple enough, right? Well i am having problems and the solution i tried did not work. The problem is that when the user mouses over the box, the text does indeed appears but stays really narrow and comes out of the bottom box, the sameway it would if overflow was set to visible. below is the standard css applied to the div box: .newevent { overflow: hidden; z-index: 0; } I Tried to fix this by setting a hover trigger, when it is activated the box widens, i thought that this would then mean there would be more space to display the text, below is the hover effect: .newevent div:hover { width: 200px; padding: 50px; background-color:#D4D4D4; border: medium red dashed; overflow: visible; z-index: 1; } How do i go about "redrawing" the text when it is hovered over, so that the text can use the new widened area rather than behaving as it is still in a narrow box.

  • Is there a concise way to map a string to an enum in Objective-C?

    - by zekel
    I have a string I want to parse and return an equivalent enum. I need to use the enum type elsewhere, and I think I like how I'm defining the class. The problem is that I don't know a good way to check the string against the enum values without being redundant about the order of the enums. typedef enum { ZZColorRed, ZZColorGreen, ZZColorBlue, } ZZColorType; - (ZZColorType)parseColor:(NSString *)inputString { // inputString will be @"red", @"green", or @"blue" (trust me) // how can I turn that into ZZColorRed, etc. without // redefining their order like this? NSArray *colors = [NSArray arrayWithObjects:@"red", @"green", @"blue", nil]; return [colors indexOfObject:inputString]; } In Python, I'd probably do something like the following, although to be honest I'm not in love with that either. ## maps url text -> constant string RED_CONSTANT = 1 BLUE_CONSTANT = 2 GREEN_CONSTANT = 3 TYPES = { 'red': RED_CONSTANT, 'green': GREEN_CONSTANT, 'blue': BLUE_CONSTANT, } def parseColor(inputString): return TYPES.get(inputString) ps. I know there are color constants in Cocoa, this is just an example.

  • when i set property(retain), one "self" = one "retain"?

    - by Walter
    although I'm about to finish my first app, I'm still confused about the very basic memory management..I've read through many posts here and apple document, but I'm still puzzled.. For example..I'm currently doing things like this to add a label programmatically: @property (retain, nonatomic) UILabel *showTime; @sythesize showTime; showTime = [[UILabel alloc] initWithFrame:CGRectMake(45, 4, 200, 36)]; [self.showTime setText:[NSString stringWithFormat:@"%d", time]]; [self.showTime setFont:[UIFont fontWithName:@"HelveticaRoundedLT-Bold" size:23]]; [self.showTime setTextColor:numColor]; self.showTime.backgroundColor = [UIColor clearColor]; [self addSubview:self.showTime]; [showTime release]; this is my current practice, for UILabel, UIButton, UIImageView, etc... [Alloc init] it without self., coz I know this will retain twice.. but after the allocation, I put back the "self." to set the attributes.. My gut feel tells me I am doing wrong, but it works superficially and I found no memory leak in analyze and instruments.. can anyone give my advice? when I use "self." to set text and set background color, does it retain one automatically? THX so much!

  • Cannot press QPushButton in a simple program

    - by shadyabhi
    Basically, I want a simple pushButton with a colorful text which when pressed exits the application. Why cant I press PushButton in this simple program. I am using QT 4.6 on Arch x86_64. #include <QtGui/QApplication> #include <QLabel> #include <QPushButton> #include<QtGui> int main(int argc, char *argv[]) { QApplication a(argc, argv); QMainWindow *Main=new QMainWindow; QPushButton *button = new QPushButton(Main); QLabel *label = new QLabel(Main); label->setText("<h2><i>Hello</i> ""<font color=red>Qt!</font></h2>"); label->setVisible(true); QObject::connect(button, SIGNAL(clicked()),label, SLOT(clear())); label->setAlignment(Qt::AlignCenter|Qt::AlignVCenter); label->setWindowTitle("HelloWorld Test Program"); Main->show(); return a.exec(); }

  • Why is my view controllers view not quadratic?

    - by mystify
    I created an UIViewController subclass, and figured out that the default implementation of -loadView in UIViewController will ignore my frame size settings in a strange way. To simplify it and to make sure it's really not the fault of my code, I did a clean test with a plain instance of UIViewController directly, rather than making a subclass. The result is the same. I try to make an exactly quadratic view of 320 x 320, but the view appears like 320 x 200. iPhone OS 3.0, please check this out: UIViewController *ts = [[UIViewController alloc] initWithNibName:nil bundle:nil]; ts.view.frame = CGRectMake(0.0f, 0.0f, 320.0f, 320.0f); ts.view.backgroundColor = [UIColor cyanColor]; [self.view addSubview:ts.view]; like you can see, I do this: 1) Create a UIViewController instance 2) Set the frame of the view to a quadratic dimension of 320 x 320 3) Give it a color, so I can see it 4) Added it as a subview. Now the part, that's even more strange: When I make my own implementation of -loadView, i.e. if I put this code in there like this: - (void)loadView { UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 320.0f)]; v.backgroundColor = [UIColor cyanColor]; self.view = v; [v release]; } then it looks right. Now lets think about that: In the first example, I do pretty much exactly the same, just that I let UIViewController create the view on it's own, and then take it over in order to change it's frame. Right? So why do I get this strange error? Right now I see no other way of messing around like that to correct this wrong behavior. I did not activate anything like clipsToBounds and there's no other code touching this.

  • manipulating radio box selection with javascript

    - by Crays
    Hi guys, i'm trying to do a poll but i designed it without any radio box in it. So i decided to make the selection being highlighted with a different background color, all is done with jquery. I set the display of the radio box to none so that it wouldn't show, gave each a unique ID. Here's the script. <form action="v_poll.php" method="post"> <ul class="voting"> <li class="voting votetext"><input type="radio" name="voting" value="a1" style="display:none;" id="a1"><a onClick="vote('a1')"Answer 1</a></li> <li class="voting votetext"><input type="radio" name="voting" value="a2" style="display:none;" id="a2"><a onClick="vote('a2')">Answer 2</a></li> <li class="voting votetext"><input type="radio" name="voting" value="a3" style="display:none;" id="a3"><a onClick="vote('a3')">Answer 3</a></li> <input type="hidden" value="1" name="id" /> <input type="submit" value="submit"> </ul> </form> <script type="text/javascript"> function vote(TheValue) { GetElementById(TheValue).checked=true; } </script> But when i checked the value of the radio box with $_POST['voting'], it is blank. Not the value assigned to the radio box. Anything i'm doing wrong? Please help. Thanks.

  • Jquery Works in FF but not IE at all

    - by Shawn
    I set up the SimpleModal plugin to work from our Ad server(Real 24/7). Essentially, attempting to make an interstitial ad. I serve a popupAd.js file from the Ad Server to our homepage(index.php), Here is the code for popupAd.js: $(document).ready(function() { $.modal('<iframe src="/welcomeAd.htm" height="525" width="562" style="border:0;" scrolling="no"/>', { closeHTML: "<a href='#' title='Close' align='right' style='color:#666>(X) Continue to website</a>", containerCss: { backgroundColor: '#fff', borderColor: "#0063dc", height: 525, padding: 0, width: 562, }, overlayCss:{ backgroundColor:"#fff", }, opacity:100, overlayClose: true }); }); This opens a modal window on the homepage which then loads welcomeAd.htm which contain nothing other than the ad call to the creative. Here is the code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd"> <html> <head> <title>Company Name</title> <!------ AD SERVER SETUP begin ------> <!------ OAS SERVER SETUP end ------> </head> <body style="margin: 0; padding: 0; width: 100%; height: 100%"> <script type="text/javascript" language="JavaScript"> <!-- AD SERVER CALL; //--> </script> </body> </html> This all works in FF but does nothing in IE, of which I am running IE7. Also, the closeHTML doesn't show up in Safari, though, the ad does.

  • Voice Recognition Google API

    - by user2966744
    thanks for reading. I'm creating a simple web based drawing app that uses speech recognition. I have created a simple page, the project is on github here: https://github.com/a5hton/speechdraw It has a 16x16 pixel grid. I would like to be able to draw on this grid by using simple words. For example if you say "right", the pixel to the right will be colored black. If you say "down" the pixel below the last one will be colored black. You can say up, down, left or right and the corresponding pixels will be colored. Saying "erase" will switch to erase mode, colouring the pixels back to their original color. Saying "lift" will lift the pen off the page. Saying "draw" will enable the draw mode. Could you please help me work out how to make this happen. Please see the simple page at to get an understanding. Thank you! Cheers, Michael

  • ListSelector applies to the entire list

    - by jax
    I have a simple list with a listselector like so. <ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_below="@+id/round" android:listSelector="#99000000" android:clickable="true" android:cacheColorHint="#00000000" android:background="#00000000"> </ListView> As you can see android:listSelector="#99000000" but the "black alpha" color is applied to the entire list, not the selected item.

  • Overriding CSS style 'display:none' in javascript

    - by jsarma
    I'm trying to add a checkbox toggle that hides and shows list elements by changing their style display attribute from "none" to "inline", but it's not working. I'm setting the attribute's style to "display:none" in the CSS file. Then I set it to "display:inline" in javascript when someone checks a box. The javascript is successfully changing the element's property to inline, but for some reason the element remains invisible. If I do the opposite, by setting the display to inline in the CSS and overriding it to none in the javascript, it works fine. I don't see why this would work one way but not the other. I'm using chrome. Here is the code. Any feedback is appreciated. CSS file: #tabmenu li[status='disabled'] a, a.active, #disabled { color: #777777; background: #DDDDDD; font: normal 1em Arial; border: 1px solid black; border-radius: inherit; padding: 0px 5px 0px 5px; margin: 0px; text-decoration: none; cursor:hand; display:none; } HTML: <ul id="tabmenu"> <li name='tab' id='tab1' selected='no' status='disabled'></li> </ul> JAVASCRIPT (from command line, or onchange of a checkbox) tab = document.getElementById('tab1'); tab.style.display = 'inline';

  • Game design flaw, need help investigating

    - by Snake
    I am not sure if I will be able to get help here but I would give it a shot. The problem is I dont know where the problem is. I have a cards game, in which when you "human" play by dragging a card, then at the end of card being dragged, a handler using postExecute is called with delay of 0.5 sec to start the next player in turn (which is a bot) The bot chooses the color and plays it and at the end of the animation (the card moving to the middle) a handler is started for the next bot and so on. Once the play reaches again to the human player, it waits for his touchs to drag the crad and start the cycle again. The problem that in production, sometimes I am getting errors. The error is resulting in somehow messing up the sequence which ends up with players having more cards than others. After investigation, I found that the transition from human to bot is the problem. Somehow, the transition is happening twice (meaning handler calling post execute twice and the bot is playing twice and everything is messed up). Its been mutliple months and I can't reproduce it (to fix it) and I cna't figure out why this is happeneing? ANY IDEA how I can go after it? How can I get more info about or how can I solve something like that? any pointer would help me

  • style ul with width to accommodate items

    - by Tallmaris
    Sorry I could not find a similar answer on SO. I have the following markup (generated by jquery ui autocomplete but this is not the issue here) <ul style="z-index: 1; display: block; border: thin solid red; width: 200px;"> <li> <a> <div style="font-size: 0.85em;"> <span style="float: right; padding-left: 10px; color: gray;"> United Kingdom </span> <span style="">text text text text text</span> </div> </a> </li> </ul> As you can see in this fiddle: http://jsfiddle.net/fVr8P/2/ the text wraps because the width is limited and the country span is "floating". What I would like would be for the width to enlarge to accommodate the full length, but if I put width: auto; it will expand to 100%. Background The ul is of course coming from jquery ui autocomplete. I am styling the results a bit using the autocomplete.html extension. Problem is that everything is working ok in firefox an chrome because the autocomplete is set to the correct width on creation. in IE this does not happen (width is too small) so the text wraps. I am hping to come to a simple css only solution, without fiddling around in jQuery.

  • Overriding CSS properties for iframe width

    - by user2898989
    I'm trying to put an iframe into a webpage, but no matter what I try to put in either the iframe properties or the custom CSS section of the website builder (or how many times I try to add !important to anything from width to right-margin), I can't get the iframe to extend rightward further than the page's preset width. Here's an example of the page and iframe that I'm working with: http://fmlcapitalinvestment.com/Search_Properties.html I need that script/iframe to be wide enough to show the search area. It seems pointless to copy and paste code and attributes I've tried setting, because nothing I do seems to have any effect, but just for showing how much I have no idea what I'm doing, here's my iframe code: <iframe id="idxFrame" style="padding:0; margin:0; padding-top: 0px; overflow-x:auto; width:1000px!important; border:0px solid transparent; background-color:transparent; max-width:none!important; right-margin:-200px!important" frameborder="0" scrolling="on" src="http://www.themls.com/IDXNET/Default.aspx?wid=8MSsp7Pf9eI55yjkDuB%2blX5awn7LnnVXh5PNYhq2ImAEQL" width="1200px" height="900px"></iframe> The "Website Builder" that I'm forced to use to make these kinds of pages is infuriating, but it does have a "Custom CSS" area where I can input additional CSS information. Is there something I could generically use to set iframes to their own widths?

  • GIT: head has dissapeared, want to merge it into master.

    - by samgoody
    The top image is the output of: git reflog. The bottom is what GITK in GIT GUI (msysgit) shows me when I look at all branch history. The last few commits do not show on GIT GUI. Why do they not show on GITK (at least as a branch or something)? How do I merge them into master? I gather this happened when I checked out tag 0.42. Why is that not the same as master? (I had tagged the master in its latest state) When I click push, why does the remote repo claim to be up to date.. shouldn't it try to update these commits into whatever branch they are in? The first of the questions is important - I would like to begin to understand what GIT is thinking. It's more oracle than logic at this point. If it makes a difference to see the earlier history, the project is a [pretty powerful] JS color picker that can be viewed here in its entirety.

  • Locking a GDI+ Bitmap in Native C++?

    - by user146780
    I can find many examples on how to do this in managed c++ but none for unmanaged. I want to get all the pixel data as efficiently as possible, but some of the scan0 stuff I would need more info about so I can properly iterate through the pixel data and get each rgba value from it. right now I have this: Bitmap *b = new Bitmap(filename); if(b == NULL) { return 0; } UINT w,h; w = b->GetWidth(); h = b->GetHeight(); Rect *r = new Rect(0,0,w,h); BitmapData *lockdat; b->LockBits(r,ImageLockModeRead,PixelFormatDontCare,lockdat); delete(r); if(w == 0 && h == 0) { return 0; } Color c; std::vector<GLubyte> pdata(w * h * 4,0.0); for (unsigned int i = 0; i < h; i++) { for (unsigned int j = 0; j < w; j++) { b->GetPixel(j,i,&c); pdata[i * 4 * w + j * 4 + 0] = (GLubyte) c.GetR(); pdata[i * 4 * w + j * 4 + 1] = (GLubyte) c.GetG(); pdata[i * 4 * w + j * 4 + 2] = (GLubyte) c.GetB(); pdata[i * 4 * w + j * 4 + 3] = (GLubyte) c.GetA(); } } delete(b); return CreateTexture(pdata,w,h); How do I use lockdat to do the equivalent of getpixel? Thanks

  • Using unions to simplify casts

    - by Steven Lu
    I realize that what I am trying to do isn't safe. But I am just doing some testing and image processing so my focus here is on speed. Right now this code gives me the corresponding bytes for a 32-bit pixel value type. struct Pixel { unsigned char b,g,r,a; }; I wanted to check if I have a pixel that is under a certain value (e.g. r, g, b <= 0x10). I figured I wanted to just conditional-test the bit-and of the bits of the pixel with 0x00E0E0E0 (I could have wrong endianness here) to get the dark pixels. Rather than using this ugly mess (*((uint32_t*)&pixel)) to get the 32-bit unsigned int value, i figured there should be a way for me to set it up so I can just use pixel.i, while keeping the ability to reference the green byte using pixel.g. Can I do this? This won't work: struct Pixel { unsigned char b,g,r,a; }; union Pixel_u { Pixel p; uint32_t bits; }; I would need to edit my existing code to say pixel.p.g to get the green color byte. Same happens if I do this: union Pixel { unsigned char c[4]; uint32_t bits; }; This would work too but I still need to change everything to index into c, which is a bit ugly but I can make it work with a macro if i really needed to.

Say if I wanted to execute functions on each of those divs, I would set up an array that contains each of the names of the divs I want to update as an element in the array of strings. ["first", "second", "third"] that I want to update. If I wanted to apply I function, I set up a for loop that iterates through each element in the array and say if I wanted to change the background color to red: function updateAllDivsInTheList() { for(var i = 0; i < array.size; i++) $("#"+array[i]).changeCssFunction(); } } Whenever I create a new div, i would add it to the array. The issue is, if I have a large number of divs that need to get updated, say if I wanted to update 1000 out of 1200 divs, it may be a pain/performance tank to have to sequentially iterate through every single element in the array. Is there some alternative more efficient way of updating multiple divs without having to sequentially iterate through every element in an array, maybe with some other more efficient data structure besides array? Or is what I am doing the most efficient way to do it? If can provide some example, that would be great.
