  • Browser: Continue gif animation after escape is pressed

    - by cottsak
    Firefox (and other browsers i believe) stop gif animation when you click the Stop button or invoke it via the Escape key. I have a text input that on change makes ajax requests to update other elements. As part of this ajaxyness i have an animated gif to show feedback. I also trap the escape key press in this input so as to clear the text field for better UX. My problem is after the escape key is pressed once, none of the ajax gifs animate anymore until the page is refreshed. Does anyone know a workaround? Stuff i've tried: I tried the e.stopPropagation(); and e.cancelBubble = true; in the function handling the e.keyCode == 27 and that didn't seem to work. I suspect that this stops trigging more js events and the browser catches the escape irrespective of js activity. I have the gif showing/hiding via adding/removing a css class so it's difficult to apply the "change gif url to reset" workaround. I dont even know if this works anyway - didn't test it. But it seems difficult. If anyone knows that this works and knows of an easy way to apply the hack with background-image: url(../images/ajax-loader_dotcirclel13x13.gif); css then please let me know.

  • "Link" against a SWC in Flex

    - by ggambett
    I'm trying to do a very simple app in Flash/Flex, that loads an image embedded in the swf itself and then shows it. The thing is I'm trying to do it using the command line only (mxmlc and compc) and without using @Embed, and failing miserably. I have a very simple Main.as : package { import flash.display.*; import flash.utils.*; public class Main extends Sprite { public function Main () : void { var pDef:Class = getDefinitionByName("icon_big.png") as Class; var _image:BitmapData = new pDef(0, 0); var pSprite:Sprite = new Sprite(); pSprite.graphics.beginBitmapFill(_image); pSprite.graphics.drawRect(0, 0, _image.width, _image.height); pSprite.graphics.endFill(); addChild(pSprite); } } } This works fine if I add icon_big.png to the Library using the Flash IDE, but I can't figure out how to do it from the command line. I'm using compc to put the png inside a swc : compc --include-file icon_big.png icon_big.png -output assets.swc This generates a 17 kb assets.swf, slightly bigger than icon_big.png. Then I try to compile and link Main.as : mxmlc -include-libraries+=assets.swc Main.as This produces a 944 byte Main.swf, which clearly doesn't include the asset, and fails at runtime. According to the mxmlc docs I found, -include-libraries should link with every class, including the ones not directly referenced by code (as is the case here, since I'm getting the class from code), and it unsurprisingly fails at runtime. Note that this same code (or, more precisely, quite equivalent code) works when used within a Flash project - I'm not looking to fix the code, but how to do in the command line whatever Flash does internally. I feel I'm just "not getting" something... any clues?

  • iPhone Dev:Blurring of CALayers when rotated

    - by user153231
    Hello All, I have a CALayer with a png image as its content.When rotation is applied the layer looks blurry. I've searched for a cause for this problem and found out that the problem might be the half pixel problem, which makes the layer blurry if its frame.origin lays on fractions like 96.5, and they suggest to make the origin a whole number. Now, my layer's origin contains fractions because of the rotation i make as in: tempLayer.anchorPoint = CGPointMake(0.5,0.5); tempLayer.position = CGPointMake(200,100); tempLayer.bounds = CGRectMake(0,0,70,88); tempLayer.transform = CATransform3DMakeRotation(10.f*M_PI/180.f, 0.f, 0.f, 1.f); tempLayer.contents = (id)myImage; Basically i have three questions: 1) Is there a better way to rotate the layer? 2) The frame values are derived from the anchorPoint, position, bounds and transform values, how can i round my frame values to integer values and keep my rotation intact? 3) Can the CGRectIntegral function help me? If yes how? Thank you all in advance.

  • Mixing RewriteRule and ProxyPass in Apache

    - by Taylor L
    I was working on debugging an issue today related to mixing mod_proxy and mod_rewrite together and I ended up having to use balancer://mycluster in the RewriteRule in order to stop receiving a 404 error from Apache. I have two questions: 1) Is there any other way to get the rewritten URL to go through the balancer without adding balancer://mycluster into the RewriteRule? 2) Is there a way to define all the parameters I defined in ProxyPass (stickysession=JSESSIONID|jsessionid scolonpathdelim=On lbmethod=bytraffic nofailover=Off) in either the <Proxy> or RewriteRule? I'm concerned the requests that match the new RewriteRule won't load balance in the same fashion as those that go through ProxyPass (like /app1/something.do)? Below are the relevant sections of the httpd.conf. I am using Apache 2.2. <Proxy balancer://mycluster> Order deny,allow Allow from all BalancerMember ajp://my.domain.com:8009 route=node1 BalancerMember ajp://my.domain.com:8009 route=node2 </Proxy> ProxyPass /app1 balancer://mycluster/app1 stickysession=JSESSIONID|jsessionid scolonpathdelim=On lbmethod=bytraffic nofailover=Off ProxyPassReverse /app1 ajp://my.domain.com:8009/app1 ...

  • Choosing circle radius to fully fill a rectangle

    - by Andy
    Hi, the pixman image library can draw radial color gradients between two circles. I'd like the radial gradient to fill a rectangular area defined by "width" and "height" completely. Now my question, how should I choose the radius of the outer circle? My current parameters are the following: A) inner circle (start of gradient) center pointer of inner circle: (width*0.5|height*0.5) radius of inner circle: 1 color: black B) outer circle (end of gradient) center pointer of outer circle: (width*0.5|height*0.5) radius of outer circle: ??? color: white How should I choose the radius of the outer circle to make sure that the outer circle will entirely fill my bounding rectangle defined by width*height. There shall be no empty areas in the corners, the area shall be completely covered by the circle. In other words, the bounding rectangle width,height must fit entirely into the outer circle. Choosing outer_radius = max(width, height) * 0.5 as the radius for the outer circle is obviously not enough. It must be bigger, but how much bigger? Thanks!

  • Eclipse and JavaFX? is it just me?

    - by jeff porter
    I'm looking at learning JavaFX. I've tried setting Eclipse to develop a small app and I've downloaded the Eclipse plugin. Eclipse JavaFX plugin BUT... it just seems, well, flakey. So I have 3 questions... 1: Is there a better plugin? 2: Or is there some great set of tutorials out there that I'm missing? 3: finally, is it meant to be easy to call Java code from FX? I'm stuggling, it there a good example somewhere? On questions 1 & 2, Eclipse underlines code in red that just shouln't be. For example.. see this image... Why does it underline bit of imports in red? I know this is little of an open ended question. So I guess my main question is this... Is my experiance of JavaFX and Eclipse the best I can hope for? Or am I missing something ? (and I'm not looking for a Yes/No response) :-) Just looking for a discussion on how best to learn/develop JavaFx.

  • Browser relative positioning with jQuery and CutyCapt

    - by Acoustic
    I've been using CutyCapt to take screen shots of several web pages with great success. My challenge now is to paint a few dots on those screen shots that represent where a user clicked. CutyCapt goes through a process of resizing the web page to the scroll width before taking a screen shot. That's extremely useful because you only get content and not much (if any) of the page's background. My challenge is trying to map a user's mouse X coordinates to the screen shot. Obviously users have different screen resolutions and have their browser window open to different sizes. The image below shows 3 examples with the same logo. Assume, for example, that the logo is 10 pixels to the left edge of the content area (in red). In each of these cases, and for any resolution, I need a JavaScript routine that will calculate that the logo's X coordinate is 10. Again, the challenge (I think) is differing resolutions. In the center-aligned examples, the logo's position, as measured from the left edge of the browser (in black), differs with changing browser size. The left-aligned example should be simple as the logo never moves as the screen resizes. Can anyone think of a way to calculate the scrollable width of a page? In other words, I'm looking for a JavaScript solution to calculate the minimum width of the browser window before a horizontal scroll bar shows up. Thanks for your help!

  • curl halts script execution

    - by Funky Dude
    my script uses curl to upload images to smugsmug site via smugsmug api. i loop through a folder and upload every image in there. but after 3-4 uploads, curl_exec would fail, stopped everything and prevent other images from uploading. $upload_array = array( "method" => "smugmug.images.upload", "SessionID" => $session_id, "AlbumID" => $alb_id, "FileName" => zerofill($n, 3) . ".jpg", "Data" => base64_encode($data), "ByteCount" => strlen($data), "MD5Sum" => $data_md5); $ch = curl_init(); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_POSTFIELDS, $upload_array); curl_setopt( $ch, CURLOPT_URL, "https://upload.smugmug.com/services/api/rest/1.2.2/"); $upload_result = curl_exec($ch); //fails here curl_close($ch); updated: so i added logging into my script. when it does fail, the logging stops after fwrite($fh, "begin curl\n"); fwrite($fh, "begin curl\n"); $upload_result = curl_exec($ch); fwrite($fh, "curl executed\n"); fwrite($fh, "curl info: ".print_r(curl_getinfo($ch,true))."\n"); fwrite($fh, "xml dump: $upload_result \n"); fwrite($fh, "curl error: ".curl_error($ch)."\n"); i also curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60*60);

  • jQuery: Stop browser scrolling on event update beyond the fold?

    - by neezer
    I have several links at the bottom of my page that update content at the top of my page (more than a viewport away). Here's the gist of what the update looks like: $('#private-photo div').fadeOut(function() { $(this).html('<%= escape_javascript(image_tag current_user.private_photo.image.url(:profile)) %>'); }).fadeIn(); Basically it's just fading out the old content and fading in the new content. My problem is that when this happens, the browser window automatically scrolls up just far enough so that the bottom of the updated content (#private-photo div) appears at the top of the browser viewport. I do not want this to happen. I want the content to be updated (still fading in and out), but without the browser viewport realigning its focus. I want to keep the animation because if the user has a big enough screen, or if they are using a link closer to the top of the page, I still want them to see the animation. Any ideas about how to prevent the browser from scrolling as described? If not, any suggestions for workarounds? FYI, I have this same problem in Safari 4, Chrome (for Mac), & Firefox 3.5. EDIT: Here's the link that calls the update action, which is itself inside a Colorbox: $('a.edit-photo').colorbox({ title: function() { return 'Edit Photo in ' + $(this).attr('rel'); }, overlayClose: false, onComplete: function() { $('#edit-photo-modal').submit(function(e) { $('#photo_submit').after('<span id="saving">Saving...</span>'); e.preventDefault(); $.post($(this).attr('action'), $(this).serialize(), function() { $('#edit-photo-modal #saving').text('Saved!'); }, "script"); }); } }); The lightbox opens, presents a form fetched through an AJAX request, then (on submit) triggers the update action mentioned above. I had these links outside of the Colorbox in an earlier design revision, and they exhibited the same problem, so I've ruled out Colorbox itself as a cause. If you need anymore info, let me know!

  • Performance of map overlay in conjunction with ItemizedOverlay is very poor

    - by oviroa
    I am trying to display one png (drawable) on a map in about 300 points. I am retrieving the coordinates from a Sqlite table, dumping them in a cursor. When I try to display them by parsing through the cursor, it takes for ever for the images to be drawn, about .5 second per image. I find that to be suspiciously slow, so some insight on how I can increase performance would help. Here is the snippet of my code that does the rendering: while (!mFlavorsCursor.isAfterLast()) { Log.d("cursor",""+(i++)); point = new GeoPoint( (int)(mFlavorsCursor.getFloat(mFlavorsCursor.getColumnIndex(DataBaseHelper.KEY_LATITUDE))*1000000), (int)(mFlavorsCursor.getFloat(mFlavorsCursor.getColumnIndex(DataBaseHelper.KEY_LONGITUDE))*1000000)); overlayitem = new OverlayItem(point, "", ""); itemizedoverlay.addOverlay(overlayitem); itemizedoverlay.doPopulate(); mFlavorsCursor.moveToNext(); } mapOverlays.add(itemizedoverlay); I tried to isolate all the steps and it looks like the slow one is this: itemizedoverlay.doPopulate(); This is a public method in my class that extends ItemizedOverlay that runs the private populate() method.

  • problem loading texture with transparency with OpenGL ES and Android

    - by Evan Kimia
    Im trying to load an image that has background transparency that will be layered over another texture. When i try and load it, all i get is a white screen. The texture is 512 by 512, and its saved in photoshop as a 24 bit PNG (standard PNG specs in the Photoshop Save for Web and Devices config window). Any idea why its not showing? The texture without transparency shows without a problem. Here is my loadTextures method: public void loadGLTexture(GL10 gl, Context context) { //Get the texture from the Android resource directory Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.m1); Bitmap normalScheduleLines = BitmapFactory.decodeResource(context.getResources(), R.drawable.m1n); //Generate texture pointers... gl.glGenTextures(3, textures, 0); //...and bind it to our array gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[1]); //Create Nearest Filtered Texture gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR_MIPMAP_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL11.GL_TEXTURE_2D, GL11.GL_GENERATE_MIPMAP, GL11.GL_TRUE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); bitmap.recycle(); //Bind our normal schedule bus map lines gl.glBindTexture(GL10.GL_TEXTURE_2D, textures[0]); //Create Nearest Filtered Texture gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR_MIPMAP_NEAREST); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL11.GL_TEXTURE_2D, GL11.GL_GENERATE_MIPMAP, GL11.GL_TRUE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_RGBA, normalScheduleLines, 0); normalScheduleLines.recycle(); }

  • Use Struct as a Ptr/class? Need a fix .NET

    - by acidzombie24
    I wrote a bunch of code and i would like to fix it the fastest way possible. I'll describe my problem in a easier way. I have apples and oranges, they are both Point and in the list apples, oranges. I create a PictureBox and draw the apple/oranges on screen and move them around and update the Point via Tag. The problem now is since its a struct the tag is a copy so the original elements in the list are not update. So, how do i update them? I consider using Point? But those seem to be readonly. So the only solution i can think of is Clear the list, iterate through all the controls then check the picturebox property to check if the image is a apple or orange then add it to a list I really only thought of this solution typing this question, but my main question is, is there a better way? Is there some List<Ptr<Point>> class i can use so when i update the apples or oranges through the tag the element in the list will update as a class would?

  • NSMutableDictionary isn't stick around long enough

    - by Sean Danzeiser
    Sorry, beginner here . . . So I create an NSMutableDictionary in my app delegate when the application launches, and then later pass it on to a view controller, as it contains options for the VC like a background image, a url I want to parse, etc. Anyway, i wrote a custom init method for the VC, initWithOptions, where I pass the dictionary on. I'm trying to use this dictionary later on in other methods - so I created a NSMutableDictionary property for my VC and am trying to store the passed options dictionary there. However, when I go to get the contents of that property in later methods, it returns null. If i access it from the init method, it works. heres some sample code: -(id)initWithOptions:(NSMutableDictionary *)options { self = [super init]; if (self) { // Custom initialization self.optionsDict = [[NSMutableDictionary alloc]initWithDictionary:options]; NSLog(@"dictionary in init method %@",self.optionsDict); that NSLog logs the contents of the dictionary, and it looks like its working. then later when I do this: - (void)viewDidLoad { SDJConnection *connection = [[SDJConnection alloc]init]; self.dataArray = [connection getEventInfoWithURL:[dict objectForKey:@"urlkey"]]; NSLog(@"dictionary in connection contains: %@", [dict objectForKey:@"urlkey"]); [_tableView reloadData]; the dictionary returns null. Ive tried adjusting the property attributes, and it didn't work with either strong or retain. Any ideas?? THANKS!!

Please remove some images and try again.</div>'); } }, inside the try block it calls: this.FileChanged = function(input) { // FileUploadManager.addFileInput(input); console.debug(input); var files = input.files; for (var i = 0; i < files.length; i++) { var file = files[i]; if (!file.type.match(/image.*/)) continue; var reader = new FileReader(); reader.onload = (function(f, isLast) { return function(e) { if (files.length == 1) { LocalStorageManager.addImage(f.name, e.target.result, false, true); LocalStorageManager.loadCurrentImage(); //foxyface.window.close(); } else { FileUploadManager.addFileData(f, e.target.result); // add multiple files to list if (isLast) setTimeout(function() { LocalStorageManager.loadCurrentImage() },100); } }; })(file, i == files.length - 1); reader.readAsDataURL(file); } return true; LocalStorageManager.addImage calls: this.setItem = function(data){ localStorage.setItem('ImageStore', $.json_encode(data)); } localStorage.setItem throws an error if too much local storage has been used. I want to catch that error in f_openFRHandler (first code sample), but it's being sent to the error console instead of the catch block. I tried the following code in my Firebug console to make sure I'm not crazy and it works as expected despite many levels of function nesting: try{ (function(){ (function(){ throw 'foo' })() })() } catch(e){ console.debug(e) } Any ideas?

  • Javascript Rich Display Component/Methodology

    - by Laramie
    quick back story-- I am working on ASP.Net based template editor that lets authors create text templates using Javascript inserted placeholder tags that will be filled in with dynamic text when the templates are used to display the final results. For example the author might create a template like The word [%12#add] was generated dynamically. The application would eventually replace the tag with a dynamic word down the road (though it's not specifically relevant to this post) The word foo was generated dynmamically. Depending on the circumstances, the template may be created in a text input, textarea or a modified version of the Ajax Control Toolkit HTML Editor. There might be 40 or more of these editable elements on the page, so using lots of stripped down or modified HTML editors would probably bog the page down too much. The problem is that the tags such as [%12#add] are displayed inline with the user text and the result is confusing and aesthetically gross. The goal is parse the contens of the source element and when a tags such as [%12#add] are encountered, display something prettier and less cryptic to the user such as a stylable element or image wherever tags such as [%12#add] occur. The application still needs the template text with the tags on postback. So the user might see The word tag placeholder was generated dynamically. but the original template would still be the value of the text input box The word [%12#add] was generated dynamically. It seems HTML editors like the ACT version and FckEditor accomplish this by rendering their output in an IFrame, but rather than kill myself trying to roll a lighter specialized version myself, I thought I'd ask if anyone knows of an existing free component or approach that has already tackled this. With good reason, I don't think S.O. allows HTML formatting, but the bold "tag placeholder" above would ideally be something like tag placeholder.

  • How can i zip files in Java and not include files paths

    - by Ignacio
    For example, i want to zip a file stored in /Users/me/Desktop/image.jpg I maded this method: public static Boolean generateZipFile(ArrayList<String> sourcesFilenames, String destinationDir, String zipFilename){ // Create a buffer for reading the files byte[] buf = new byte[1024]; try { // VER SI HAY QUE CREAR EL ROOT PATH boolean result = (new File(destinationDir)).mkdirs(); String zipFullFilename = destinationDir + "/" + zipFilename ; System.out.println(result); // Create the ZIP file ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFullFilename)); // Compress the files for (String filename: sourcesFilenames) { FileInputStream in = new FileInputStream(filename); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(filename)); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file out.close(); return true; } catch (IOException e) { return false; } } But when i extract the file, the unzipped files have the full path. I don't want the full path of each file in the zip i only want the filename. How can i made this?

  • Can't get focus on a TextBox inside a ListBox using Silverlight

    - by Steve Temple
    I'm having a little trouble in silverlight with a listBox containing databound textBox elements. The items display correctly in the list and the textBox is populated correctly but I can't get focus on the text box in the list. If I hover over the edges of the textBox it highlights but it won't let me click into it to edit the text. Any ideas? My XAML looks like this: <ListBox x:Name="listImages"> <ListBox.ItemTemplate> <DataTemplate> <Grid x:Name="LayoutRoot" Background="White"> <Image Height="102" HorizontalAlignment="Left" Name="imgThumb" Stretch="UniformToFill" VerticalAlignment="Top" Width="155" Source="{Binding ImageFilename, Converter={StaticResource ImageConverter}}" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="154,25,0,0" Name="txtAltText" VerticalAlignment="Top" Width="239" Text="{Binding Alt}" /> <dataInput:Label Height="19" HorizontalAlignment="Left" Margin="154,6,0,0" Name="lblAltText" VerticalAlignment="Top" Width="239" Content="Alt Text" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox>

  • MXML composite container initialization error

    - by mkorpela
    I'm getting an odd error from my composite canvas component: An ActionScript error has occurred: Error: null at mx.core::Container/initialize()[C:\autobuild\galaga\frameworks\projects\framework\src\mx\core\Container.as:2560] at -REMOVED THIS FOR STACK OVERFLOW-.view::EditableCanvas/initialize()[.../view/EditableCanvas .... It seems to be related to the fact that my composite component has a child and I'm trying to add one in the place I'm using the component. So how can I do this correctly? Component code looks like this (EditableCanvas.mxml): <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script> <mx:Image id="editTextImage" source="@Embed('/../assets/icons/small/edit.png')"/> </mx:Canvas> The code that is using the code looks like this: <view:EditableCanvas width="290" height="120" backgroundColor="#FFFFFF" horizontalScrollPolicy="off" borderStyle="solid" cornerRadius="3"> <mx:Text id="textContentBox" width="270" fontFamily="nautics" fontSize="12" text="{_text}"/> </view:EditableCanvas>

  • Center aligned form with equal width labels

    - by James Goodwin
    I have a very simple web form which consists of labels and input fields, however I can not seem to find a way of aligning the form in the center of the page and for the labels to have an equal width so that they appear neatly next to each other, one under the other. The structure of my page is basically: <body> <div class="form"> <form method="post"> <fieldset> <label>Mobile:</label><input type="text" name="msisdn"><br/> <label>Code:</label><input type="text" name="code"><br/> <br/> <input type="image" src="submit-button.gif" alt="Submit"> <br/> <input type="checkbox" name="ts_and_cs"><label> Accept Terms and Conditions</label> <br/><br/> </fieldset> </form> </div> </body> Usually I would fix this by doing float:left on the label fields and setting a width on the labels, however for this I need the labels and input fields to be centered on the page. Also I am not able to set the width of the page (or any containing divs) as the page will be displayed on mobile devices with different screen sizes. Any suggestions as to how best style the form? Thanks
