  • How to permanently leave a CALayer rotated at its final location?

    - by David
    Hello, I am trying to rotate a CALayer to a specific angle however, once the animation is done, the layer jumps back to its original position. How would I rotate the layer properly so that it stays at its final destination? Here is the code that I am using CABasicAnimation *rotationAnimation =[CABasicAnimation animationWithKeyPath:@"transform.rotation.z"]; //Rotate about z-axis [rotationAnimation setFromValue:[NSNumber numberWithFloat:fromDegree]]; [rotationAnimation setToValue:[NSNumber numberWithFloat:toDegree]]; [rotationAnimation setDuration:0.2]; [rotationAnimation setRemovedOnCompletion:YES]; [rotationAnimation setFillMode:kCAFillModeForwards]; Any suggestions? Thank you.

  • popup panel that docks to the bottom of the screen

    - by Michael Wiles
    How do I create a pop panel that docks to the bottom of the screen... The way that I'm doing this is by setting the styling as such: bottom: 10px; position: absolute; This will always set the panel to 10 px from the bottom of the browser window. The problem is that gwt (or gwtp for that matter) is insisting on setting the right and the top of the panel and thus overriding my styling. If I use chrome's element explorer and disable the right and top style rules I get the correct behaviour so one way of doing it is somehow disabling gwt setting of the location of the panel on the screen...?

  • VSTO addin (2003-2007) Ms Word & Webservices

    - by Daveo
    Hi, I am planning on starting my 1st VSTO project. What I want to be able to do is: Download and Upload versions of a MS Word document to a web service. With authentication by overriding the save button Call a web service to list a bunch of tag that can be inserted into a document. When a user double clicks a tag the selected tag is inserted into the cursor position. I am pretty sure this is all possible just want some confirmation? Also would like to know how long would it take to make something like this. I think the biggest issue will be authentication and listing exiting files to download then allowing the user to download a .doc and restore previous versions of that file via the web service.

  • Drag and drop an image from desktop to a web text editor (implementation in javascript)

    - by fatmatto
    I tried to write reasonably short title but i failed i guess.. Hi everybody here's what i'm trying to do: I want to implement a web text editor able to recognize when the user drag a image file over it's editing surface and it automa(gically) starts the upload and insert the image near the cursor position. In other words i don't want the user to do the usual "insert-image-browse-ok". Atm i am not very good at javascript ... i know JQuery but i have not a clear idea about how to implement this... i don't know if there's an event handler able to help me in this situation... if not then there should be i think or web apps would miss some kind of interactivity. I've heard miracles about HTML5 could it help me? I've seen such things in Google Wave but that surface doesn't seem to be a form field... google lab's black magic i guess.... Thank you in advance.

  • HTML: How to get a child element to show behind (lower z-index) than its parent

    - by dclowd9901
    I need for a certain dynamic element to always appear on top of another element, no matter what order in the DOM tree they are. Is this possible? I've tried z-index (with position: relative), and it doesn't seem to work. I hate to be vague, but this is the simplest way I can think of asking this question without explaining its purpose ad nauseum. So, to recap, I need <div class="a"> <div class="b"></div> </div> <div class="b"> <div class="a"></div> </div> To display exactly the same when rendered. And for flexibility purposes (I'm planning on distributing a plugin that needs this functionality), I'd really like to not have to resort to absolute or fixed positioning.

  • Not getting stage.stageWidth and stageHeight on Firefox 3.5

    - by Qpixo
    Here's a problem that I've been tried to figure out but still couldn't get the right method to fix it yet. I'm having issue regarding the display when using Firefox 3.5 on MAC, I can see my menu and the display is correct. The menu just position above what it supposed to be positioned. It works fine with Safari on MACOSX. My flash size is: 1440x750 It looks like Firefox can't recognize stage.StageWidth and stage.StageHeight. It returns 0. Some suggest implementing was to pass in the actual width and height of movie via FlashVars. The movie uses these instead of stage.stageWidth and stage.stageHeight Does anyone have an example of code of how to fix that issue?? Appreciated to point me out the right way

  • How to observe NSScroller changes?

    - by Paperflyer
    I have an NSScrollView subclass and I would like to update another NSView based on the current scroll position. I tried KVC-observing the value of [self horizontalScroller] but that never gets called. // In awakeFromNib [[self horizontalScroller] addObserver:self forKeyPath:@"value" options:NSKeyValueObservingOptionNew context:NULL]; // Later in the file - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if (object == [self horizontalScroller] && [keyPath isEqualToString:@"value"]) { // This never gets called } } Do you see an error in my reasoning or know a better method of how to observe the scrolling of an NSScrollview?

  • IE - Color transparent not working

    - by poru
    Hello, I have a problem with the IE (what else?): I generate content with CSS which has also a background-image. I looks like that: #nav ul li:after { content: "--"; position: relative; z-index: 99; background: transparent url(image.png); color: transparent; } The text color is in non-IE-browsers transparent, but in all IE browsers it's black and you could see it. How could I make the text transparent/unvisible? I tried already: visibility - opacity - filter - text-indent ... But none did his job right, either it disappears (with it background which I need) or the attribute doesn't apply.

  • C++ Beginner - Best way to read 3 consecutive values from the command line?

    - by Francisco P.
    Hello everyone, I am writing a text-based Scrabble implementation for a college project. The specification states that the user's position input must be read from single line, like this: Coordinates of the word's first letter and orientation (<A – P> <1 – 15> <H ou V>): G 5 H G 5 H is the user's input for that particular example. The order, as shown, must be char int char. What is the best way to read the user's input? cin >> row >> column >> orientation will cause crashes if the user screws up. A getline and a subsequent string parser are a valid solution, but represent a bit of work. Is there another, better, way to do this, that I am missing? Thanks for your time!

  • Simple Emacs keybindings

    - by User1
    I have two operations that I do all the time in Emacs: Create a new buffer and paste the clipboard. [C-S-n] Close the current buffer. [C-S-w] Switch to the last viewed buffer [C-TAB] I feel like a keyboard acrobat when doing the first two operations. I think it would be worth trying some custom keybindings and macros. A few questions about this customization: How would I make a macro for #1? Are these good keybindings (i know this is a bit subjective, but they might be used by something popular that I don't use) Has anyone found a Ctrl-Tab macro that will act like Alt-Tab in Linux/Windows? Specifically, I want it have a stack of buffers according to the last viewed timestamp (most recent on top). I want to continue cycling through the stack until I let go of the ctrl key. When the ctrl key is released, I want the current buffer to get an updated position on the stack.

  • Scale div in an upwards direction, instead of down?

    - by Derrick
    I have a custom info window over a google map, sometimes these info windows contain an image. When they do, the info window scales down over the marker it is positioned over as soon as the image has finished loading. So the images take longer to load and the div's position has already been calculated by the time the image is finished loading. I do believe there is a way of checking if an image has finished loaded, but that seems a long route - is there not a simple way with JS or CSS to get the div to scale upwards instead of down. Anyone have any clues?

  • Ruby on Rails, PHP or C++ for web social network

    - by faya
    Hello, I have chosen diploma work in university. It's a mini social network. But now I am really stuck with which technology I should stick. I am average at C++ ISAPI web services development, below average PHP(had few projects with it) and new to Ruby and its framework RAILS. I have a deadline 1.5 month to develop it(about 5 hours every day after my full time job). Also I heard that its very easy to learn and develop with Ruby on Rails. Considering C++ I know that I have to do lots of coding and work by myself and PHP looks almost the same to me. So I am looking for you skilled developers advise what would you do in my position? Learn RoR, stick with C++ or PHP or maybe use something else?

  • Mouseup not working after mousemove on img

    - by leyou
    I'm trying to do a simple drag script. The idea is to save the position when the mouse is down, update the view while the mouse is moving, and stop when mouse is up. Problem, mouseup event isn't working properly. See the code: var target = $('a') var pos = 0; var dragging = false; $(document).mousedown(function(e) { pos=e.pageX; dragging = true }) $(document).mouseup(function() { dragging = false }) $(document).mousemove(function(e) { if(dragging){ target.css('left', e.pageX-pos); } }) ? Why mouseup works with a "a" tag: http://jsfiddle.net/leyou/c3TrG/1/ And why mouseup doesn't work with a "img" tag: http://jsfiddle.net/leyou/eNwzv/ Just try to drag them horizontally. Same probleme on ie9, ff and chrome.

  • How do I open a hardware accelarated DirectX window on a secondary screen

    - by user567021
    I'm looking to create a hardware accelarated DirectX (9 at the moment) window on a secondary screen. This screen is connected to the same graphics display as the primary screen (at least at the moment). Currently, when I try to open the window on the secondary screen based on window position or by dragging it there, CPU usage jumps by about 10%, which seems to indicate that windows is switching to a software fallback rather than the hardware accelaration. Machine is windows XP running a NVIDIA graphics card (varying cards as this runs on several machines), with the latest driver. It's also running CUDA at the same time to produce the images if that matters. Programming language is c++, manual window and message queue creation, no tookbox used at the moment to manage the GUI Thanks

  • In CouchDB, how to get documents limited on value in related document? In terms of SQL, how to make WHERE on JOINed table

    - by amorfis
    Crossposting from [email protected] Assume we have two kind of documents in CouchDB. Person and Car: Person: _id firstname surname position salary Car: _id person_id reg_number brand So there is one to many relationship. One person can have many cars. I can construct map function to get every person and his/her car next to each other. In such case key is array [person.id, 0] and [car.person_id, 1]. What I can't do, is limiting this view to owners of specific brand only, e.g. if I need salaries of owners of Ferrari.

  • Bitmap manipulation in C++ on Windows

    - by Oliver
    Hi, I have myself a handle to a bitmap, in C++, on Windows: HBITMAP hBitmap; On this image I want to do some Image Recognition, pattern analysis, that sort of thing. In my studies at University, I have done this in Matlab, it is quite easy to get at the individual pixels based on their position, but I have no idea how to do this in C++ under Windows - I haven't really been able to understand what I have read so far. I have seen some references to a nice looking Bitmap class that lets you setPixel() and getPixel() and that sort of thing, but I think this is with .net . How should I go about turning my HBITMAP into something I can play with easily? I need to be able to get at the RGBA information. Are there libraries that allow me to work with the data without having to learn about DCs and BitBlt and that sort of thing?

  • Getting notification / listener when action is performed (chimpChat / monkeyrunner tool)

    - by Dr. AtZe
    I want to get a notification if someone has performed an action in an android app from outside of the app. I don't want to make any (android) code changes. To do the actions I use the Chimpchat.jar, the .jar that the monkeyrunner tool uses. To be clear: Can I get a notification or register listeners on components from outside of the app? e.g. Run my android app My java application links into the device with chimpChat via the adb The user touches a button My java application gets a notification what was performed = am I able to get that information? If not, am I able to get the information on which position the tab was? Hopefully it's clear what I want to do. Thanks, soeren

  • PHP search multidimensional array for value, then place that element at start of array

    - by BobFlemming
    I need to search this array: cars - [0] -make : Ford -model: Escort -year: 1991 [1] -make: Honda -model: Civic -year: 1996 [2] -make: Vauxhall -model: Astra -year: 1972 And if (for example) the model is "Civic" , place that 'car' at position 0. So the end array would be like: cars - [0] -make: Honda -model: Civic -year: 1996 [1] -make : Ford -model: Escort -year: 1991 [2] -make: Vauxhall -model: Astra -year: 1972 I've tried some usort variations: function typeSort($a, $b) { if ($a['model'] == 'Civic' ) { return 0; } return ($a['model'] < $b['model']) ? -1 : 1; } but this is just returning 1

  • SQL to get range of results in alphabetical order

    - by Tom Gullen
    I have a table, tblTags which works in much the same way as StackOverflows tagging system. When I view a tags page, let's say the tag Tutorial I want to display the 10 tags before and after it in alphabetical order. So if we are given the tag Tutorial of ID 30 how can we return a record set in the order resembling: Tap Tart > Tutorial Umbrellas Unicorns Xylaphones I have thought of ways of doing this, badly, in my opinion as they involve retrieving ugly amounts of data. I'm not sure if it's possible to do something along the lines of (pseudo): SELECT RANGE(0 - 30) FROM tblTags ORDER BY Name ASC But how do you know the position of the tutorial tag in the list in an efficient manner without traversing the entire list until you find it? I'm using SQL Server 2008 R2 Express with LINQ if it makes any difference, SQL queries or LINQ would be great answers, thanks!

  • iPhone SDK: Do I need to ask user for permissions to use GPS?

    - by RaYell
    In my iPhone application I need to use GPS (CoreLocation to be exact) to get current position of the device. I know that most (if not all) applications using GPS have a popup implemented asking the user to allow GPS access. Is that done automatically by the iPhone SDK or should I implement such functionality myself? I've tried to run my app on iPhone Simulator and it didn't ask for permissions at all so I'm wondering if the same thing will happen on the actual phone. And if I implement that itself and the SKD provides that out-of-the-box then I'll have two confirmation in my app which I don't want.

  • In python writing from XML to CSV, encoding error

    - by user574435
    Hi, I am trying to convert an XML file to CSV, but the encoding of the XML ("ISO-8859-1") apparently contains characters that are not in the ascii codec which Python uses to write rows. I get the error: Traceback (most recent call last): File "convert_folder_to_csv_PLAYER.py", line 139, in <module> xml2csv_PLAYER(filename) File "convert_folder_to_csv_PLAYER.py", line 121, in xml2csv_PLAYER fout.writerow(row) UnicodeEncodeError: 'ascii' codec can't encode character u'\xe1' in position 4: ordinal not in range(128) I have tried opening the file as follows: dom1 = parse(input_filename.encode( "utf-8" ) ) and I have tried replacing the \xe1 character in each row before it is written. Any suggestions?

  • Ref to map vs. map to refs vs. multiple refs

    - by mikera
    I'm working on a GUI application in Swing+Clojure that requires various mutable pieces of data (e.g. scroll position, user data, filename, selected tool options etc.). I can see at least three different ways of handling this set of data: Create a ref to a map of all the data: (def data (ref { :filename "filename.xml" :scroll [0 0] })) Create a map of refs to the individual data elements: (def datamap { :filename (ref "filename.xml") :scroll (ref [0 0]) })) Create a separate ref for each in the namespace: (def scroll (ref [0 0])) (def filename (ref "filename.xml")) Note: This data will be accessed concurrently, e.g. by background processing threads or the Swing event handling thread. However there probably isn't a need for consistent transactional updates of multiple elements. What would be your recommended approach and why?

The frame remains same in both modes. Please give me idea how it will be solved in the case of navigation controller image.
