  • Button color in Navigation bar - iPhone

    - by Mladen
    Hi guys, How to set this yellow button to be gray tinted one. I have tried adding image, but no luck Here is the screenshot: Here is my current code: (id)initWithStyle:(UITableViewStyle)style { if (self = [super initWithStyle:style]) { UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Settings", @"") style:UIBarButtonItemStyleDone target:self action:@selector(GoToSettings)]; [addButton setImage:[[UIImage imageNamed:@"bg_table.png"] retain]]; self.navigationItem.rightBarButtonItem = addButton; self.navigationItem.hidesBackButton = TRUE; self.view.backgroundColor = [UIColor blackColor]; } return self; }

  • Faster way to iterate through a jagged array?

    - by George Johnston
    I would like to iterate through an array that covers every pixel on my screen. i.e: for (int y = 598; y > 0; y--) { for (int x = 798; x > 0; x--) { if (grains[x][y]) { spriteBatch.Draw(Grain, new Vector2(x,y), Color.White); } } } ...my texture is a 1x1 pixel image that is drawn to the screen when the array value is true. It runs decent -- but there is definitely lag the more screen I cover. Is there a better way to accomplish what I am trying to achieve?

  • Using LINQ to query database through a proxy server of some kind?

    - by Mustafakidd
    Hey All Sorry for using (perhaps) the wrong lingo, but my question may be clearer if you view this diagram as you read it. http://dl.dropbox.com/u/13256/DIAGRAM.PNG Our client is requiring us to adhere to the server configuration (poorly) diagrammed in the above image. The web server is accessible over port 80 and is where our web application is hosted - a second firewall permits this web server to access a second server which in turn is the only server permitted to access the database server. My question is: How do I deploy a web application that uses LINQ-to-SQL in this environment? Is there a way to proxy my LINQ queries through the app server so that the database connection goes through that server? This is uncharted territory for me, as we always have had access to the DB server directly from our web server in the past. Any help is appreciated. Thanks Mustafa

  • Markup filter wanted for a public website

    - by sibidiba
    Developing a community site where everyone can post text, I'm looking for a markup filter: What is not part of the markup must be escaped (htmlspecialchars()) as it is. Should turn URL-s automatically into links Should support some form of basic markups (bold, image, url, pre, list) Should have a simple parser, that turns user input text into HTML Content on the site is public to everyone, XSS must not allowed to happen. What do you suggest? What markup language in the first place? BBCode? Wiki? Markdown? Are there any complete API-s with good examples? PHP is available on the server side. If there is a WYSIWYG-like texarea in addition (like here on SO) that would be a fantastic bonus!

  • Flash overlay snagging on underlying divs

    - by hfidgen
    Flash overlay snags on underlying divs. What is the solution? I'm using Shadowbox to overlay a Flash file on my page, but the movement within the Flash file causes it to break or "shear" where the movie comes across the divs in the HTML hidden below. The screenshot shows it far better than I could explain ;) If you move the mouse, or tap the keyboard to "focus" the screen back on the Flash it all works seamlessly. Interestingly this seems worse in Firefox than the other browsers. Flash error image

  • Is there any simple way to test two PNGs for equality?

    - by Mason Wheeler
    I've got a bunch of PNG images, and I'm looking for a way to identify duplicates. By duplicates I mean, specifically, two PNG files whose uncompressed image data are identical, not necessarily whose files are identical. This means I can't do something simple like compare CRC hash values. I figure this can actually be done reliably since PNGs use lossless compression, but I'm worried about speed. I know I can winnow things down a little by testing for equal dimensions first, but when it comes time to actually compare the images against each other, is there any way to do it reasonably efficiently? (ie. faster than the "double-for-loop checking pixel values against each other" brute-force method?)

  • Styling a hr for internet explorer

    - by Qwibble
    Hey, in my quest to create as image light a site as possible, I'm looking to create two tone hr's. I've achieved this in modern browsers, but want to achieve the same effect in ie6 and 7. The current code I am using is hr { border-bottom:1px solid #FFFFFF; border-top:1px solid #dcdcdc; clear:both; height:0; border-left:0px; border-right:0px; } I've tried, with no success to make this work in ie6 and 7 without having to target the browsers specifically. Any thoughts? (Heres my current project where I am employing this code, and looking to make it cross browser - http://www.qwibbledesigns.co.uk/preview/aurelius/ ) Cheers Matt

  • UIAlertView with subview animating to new view crashes app

    - by William
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Congratulations" message:message delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"View", nil]; UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(110, 100, 80, 80)]; NSString *imagePath = [NSString stringWithFormat:@"%@", [Array objectAtIndex:x]]; UIImage *bkgImg = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:imagePath ofType:@"png"]]; imageView.image = bkgImg; [bkgImg release]; [alert addSubview:imageView]; [imageView release]; [alert show]; [alert release]; That is the code that I am using to create the alert view. Currently, I have it set up so if the user presses one of the buttons, it will load up a new viewcontroller. It worked fine until I added a subview to the UIAlertView. Now, whenever it animates to the new screen, it just crashes the program. I am fairly new to iPhone development and any help would be appreciated.

  • unevenly centered subplots in matplotlib in Python?

    - by user248237
    I am plotting a simple pair of subplots in matplotlib that are for some reason unevenly centered. I plot them as follows: plt.figure() # first subplot s1 = plt.subplot(2, 1, 1) plt.bar([1, 2, 3], [4, 5, 6]) # second subplot s2 = plt.subplot(2, 1, 2) plt.pcolor(rand(5,5)) # add colorbar plt.colorbar() # square axes axes_square(s1) axes_square(s2) where axes_square is simply: def axes_square(plot_handle): plot_handle.axes.set_aspect(1/plot_handle.axes.get_data_ratio()) The plot I get is attached. The top and bottom plots are unevenly centered. I'd like their yaxis to be aligned and their boxes to be aligned. If I remove the plt.colorbar() call, the plots become centered. How can I have the plots centered while the colorbar of pcolor is still shown? I want the axes to be centered and have the colorbar be outside of that alignment, either to the left or to the right of the pcolor matrix. image of plots link thanks.

  • How can I plot NaN values as a special color with imshow in matplotlib?

    - by Adam Fraser
    example: import numpy as np import matplotlib.pyplot as plt f = plt.figure() ax = f.add_subplot(111) a = np.arange(25).reshape((5,5)).astype(float) a[3,:] = np.nan ax.imshow(a, interpolation='nearest') f.canvas.draw() The resultant image is unexpectedly all blue (the lowest color in the jet colormap). However, if I do the plotting like this: ax.imshow(a, interpolation='nearest', vmin=0, vmax=24) --then I get something better, but the NaN values are drawn the same color as vmin... Is there a graceful way that I can set NaNs to be drawn with a special color (eg: gray or transparent)?

  • Masks and transparency

    - by Henrik
    Hi, I'm fairly new to Shoes and ran into two problems. First I want to set a mask using a partially transparent png, like this: mask do image "images/stencilMask.png" end Is this possible somehow or can only vector shapes be used? Apart from that, I noticed a small bug(?) when trying to set a transparent color as a stroke on any kind of text, like this: title "Hello", :stroke => rgb(1.0, 0.0, 0.0, 0.5) The transparency simply isn't applied. Am I doing anything wrong, or is this actually a bug? Cheers and thanks for all answers

  • NSScrollView jumping to bottom on scroll

    - by Nick Locking
    I have an NSScrollView containing an NSImageView, which resizes based on various factors. When it resizes I have generally changed the image, so I scroll the NSScrollView to the top. This works fine. However, when I start to scroll the NSScrollView again, it moves a few pixels and then (most of the time) jumps to the bottom of the scroll. After it jumps once, it works as normal until I move the scroller to the top again. This is driving me insane. All I'm really doing is this: [_imageView setImage: anNSImage]; NSRect frame; NSSize imageSize = [anNSImage] size]; frame.size = imageSize; frame.origin = NSZeroPoint; [_imageView setFrame: frame]; [[_mainScrollview contentView] scrollToPoint: NSMakePoint(0, [_imageView frame].size.height - [_mainScrollview frame].size.height)];

  • How to achieve a palette effect on iPhone using OpenGL

    - by Joe
    I'm porting a 2d retro game to iPhone that has the following properties: targets OpenGL ES 1.1 entire screen is filled with tiles (textured triangle strip tile textured using a single 256x256 RGBA texture image the texture is passed to OpenGL once at the start of the game only 4 displayed colours are used one of the displayed colours is black The original game flashed the screen when time starts to run out by toggling the black pixels to white using an indexed palette. What is the best (i.e. most efficient) way to achieve this in OpenGL ES 1.1? My thoughts so far: Generate an alternative texture with white instead of black pixels, and pass to OpenGL when the screen is flashing Render a white poly underneath the background and render the texture with alpha on to display it Try and render a poly on top with some blending that achieves the effect (not sure this is possible) I'm fairly new to OpenGL so I'm not sure what the performance drawbacks of each of these are, or if there's a better way of doing this.

  • Using Windows media foundation

    - by Martin Beckett
    Ok so my new gig is high performance video (think Google streetview but movies) - the hard work is all embedded capture and image processing but: I was looking at the new MS video offerings to display content = Windows Media Foundation. Is anyone actually using this ? There are no books on the topic. The only documentation is a developer team blog with a single entry 9 months old. I thought we had got past having to learn an MS api by spying on the com control messages! Is it just another wrapper around the same old activeX control?

  • How to properly use Gearman with my PHP application?

    - by luckytaxi
    For now I just want to use Gearman for background processing. For example, I need to email a recipient that they have a private message waiting for them once the sender submits their message into the DB. I assume I can run the worker/client and server on my primary server but I have no problems offloading some of the tasks to a different web server. Anyways, my question is how do I handle multiple "functions?" Let's say I need a job that handles the email portion and a job to handle image manipulation. Can I have multiple functions in the worker? I've followed a couple of examples I found online but each example only shows one function being initialized. Do I have to start up multiple "workers" to handle multiple functions?

  • Blackberry custom slideshow-style BitmapField manager

    - by Diego Tori
    Right now, I'm trying to figure out how to implement the following: Suppose I have a custom Manager that has about 10 or so BitmapFields layed out in a horizontal manner (similar to a slideshow contained in a HFM ) . What I want to achieve is to be able to move the image HFM via touchEvent horizontally, where a BitmapField would take focus on the left-hand side of the custom Manager. In other words, will I have to give a value to setHorizontalScroll and if so, is it a matter of just incrementing that value when the user makes a left or right touch event. Also, how can I get the focus of a Field within a given position on the screen (i.e. the left-most Field on the HFM) when the HFM is scrolling sideways via touchEvent?

  • I have lots of images on a html page - how can i make certain ones load first (or certain ones load

    - by imlostmike
    Hi, i have a page with the main content area being big thumbnails, but elsewhere on the page are about 100-200 other (smaller) thumbs that are not important but must still show. What ways do i have to make the main ones show first (or the unimportant ones show last)? I was thinking of these ways: JS load: on page load (once it has finished loading), use a jquery's append() (or whatever other way) to write the html with the image code Set all unimportant images inside a div with style="display:none;". Then once the page has loaded, use JS to set it as visible what do you think is the best way?

  • IPhone XCode programming: view called from a navigation view doesn't set its IBOutlet attributes

    - by Antonio Murgia
    I created a view Called ProgrammaView that appears when a row of a table is clicked. This view has a UILabel, a UIImageView and a UITextView. Now. ProgrammaView's Outlets have to be changed by the parameter passed to a method of the view called iniz. in this image there is first the ProgrammaView.h and then the method iniz. The problem is that the label and other stuff doesn't change! I checked 3 million times that everything between the xib file and the controller is linked. The trick to call iniz in the other viewcontrollers works well in other part of the program so i think is not that the problem. Thank you in advance!

I also wonder how to use FileReference to upload this file without prompting a dialog for user to select file. Thank you so much :)

  • help me pick the right iPhone audio class - MPMoviePlayer vs AVAudioPlayer vs MPMusicPlayer

    - by huevos de oro
    Does anyone know of a good tutorial on the distinction between the MPMoviePlayer vs AVAudioPlayer vs MPMusicPlayer? I want to play audio from an mp3 file available at an external URL. Ideally it is played in an iPod-like audio view. I toyed with MPMoviePlayer but it appears to be more suitable for video, as when audio starts a "movie playing" message displays, the controls disappear and a white quicktime splash page displays. I would like the standard ipod audio controls to display all the time, and to customize the image behind them.

  • How can I render a Batik SVG Java object in the view portion of a Spring MVC application?

    - by mattblang
    I am creating and manipulating a SVGOMDocument object in a controller method. How can I render this object in a JSP view? I get very close with the following controller method and <object> tag. @RequestMapping(value = "/seal") public ResponseEntity<SVGDocument> createSeal() throws IOException { InputStream file = new ClassPathResource("seal.svg").getInputStream(); String parser = XMLResourceDescriptor.getXMLParserClassName(); SAXSVGDocumentFactory factory = new SAXSVGDocumentFactory(parser); SVGDocument svg = (SVGDocument) factory.createDocument("http://www.w3.org/2000/svg", file); svg.getElementById("name").getFirstChild().setNodeValue("a test name"); return new ResponseEntity<SVGDocument>(svg, HttpStatus.OK); } <object data="/seal" type="image/svg+xml"></object> This displays a string of XML that is a SVG. The string is in quotes with every XML quote escaped.
