Random point on VideoDisplay isn't accurate enough

- by Mike

For a schoolassigment me and some buddies of mine are creating an application that is showing many similarities with the C-Mon & Kypski musicvideo on www.oneframeoffame.com. The application is being developed in Flex. We want to get a random point of a clip, let it pause so a user can mimic the pose and make a snapshot out of it. What i managed to do is get a random point of the movie. I did this by getting a random value between 0 and de total duration of the movie. But what i didn't managed to do is let the screen pause on every 24st of a frame. As the movie concist out of 24FPS. It looks like the the random value of the movie that is being requested is being rounded by the movie itself. As example: There appears to be no difference between the frames requested at 2.40 or 2.41. It appears it got something to do with keyframing i've read on the Adobe® Flex™ 3.5 Language Reference. The movie is a FLV file and i use the VideoDisplay object to display the movie. Does someone is familiar with this or knows a solution to my problem? Thanks in advance

Using java2d user space measurements with TextLayout and LineBreakMeasurer

- by Andrew Wheeler

I have a java2d image defined in user space (mm) to print an identity card. The transformation to pixels is by using an AffineTransform for the required DPI (Screen or print). I want to wrap text across several lines but the the TextLayout does not respect user space co-ordinates. private void drawParagraph(Graphics2D g2d, Rectangle2D area, String text) { LineBreakMeasurer lineMeasurer; AttributedString string = new AttributedString(text); AttributedCharacterIterator paragraph = string.getIterator(); int paragraphStart = paragraph.getBeginIndex(); int paragraphEnd = paragraph.getEndIndex(); FontRenderContext frc = g2d.getFontRenderContext(); lineMeasurer = new LineBreakMeasurer(paragraph, frc); float breakWidth = (float)area.getWidth(); float drawPosY = (float)area.getY(); float drawPosX = (float)area.getX(); lineMeasurer.setPosition(paragraphStart); while (lineMeasurer.getPosition() < paragraphEnd) { TextLayout layout = lineMeasurer.nextLayout(breakWidth); drawPosY += layout.getAscent(); layout.draw(g2d, drawPosX, drawPosY); drawPosY += layout.getDescent() + layout.getLeading(); } } The above code determines font metrics using user space sizing of the Font and thus turn out rather large. The font size is calculated as best vertical fit for the number of lines in an area with the calculation as below. E.g. attr.put(TextAttribute.SIZE, (geTextArea().getHeight() / noOfLines - LINE_SPACING) ); When using g2d.drawString("Some text to display", x, y); the font size appears correct. Does anyone have a better way of doing text layout in user space co-ords?

Flex List ItemRenderer with image looses BitmapData when scrolling

- by Dominik

Hi i have a mx:List with a DataProvider. This data Provider is a ArrayCollection if FotoItems public class FotoItem extends EventDispatcher { [Bindable] public var data:Bitmap; [Bindable] public var id:int; [Bindable] public var duration:Number; public function FotoItem(data:Bitmap, id:int, duration:Number, target:IEventDispatcher=null) { super(target); this.data = data; this.id = id; this.duration = duration; } } my itemRenderer looks like this: <?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" > <fx:Script> <![CDATA[ import mx.collections.ArrayCollection; ]]> </fx:Script> <s:Label text="index"/> <mx:Image source="{data.data}" maxHeight="100" maxWidth="100"/> <s:Label text="Duration: {data.duration}ms"/> <s:Label text="ID: {data.id}"/> </mx:VBox> Now when i am scrolling then all images that leave the screen disappear :( When i take a look at the arrayCollection every item's BitmapData is null. Why is this the case?

What programming hack from your past are you most ashamed of?

- by LeopardSkinPillBoxHat

We've all been there (usually when we are young and inexperienced). Fixing it properly is too difficult, too risky or too time-consuming. So you go down the hack path. Which hack from your past are you most ashamed of, and why? I'm talking about the ones where you would be really embarrassed if someone could attribute the hack to you (quite easily if you are using revision control software). One hack per answer please. Mine was shortly after I started in my first job. I was working on a legacy C system, and there was this strange defect where a screen view failed to update properly under certain circumstances. I wasn't familiar with how to use the debugger at this time, so I added traces into the code to figure out what was going on. Then I realised that the defect didn't occur anymore with the traces in the code. I slowly backed out the traces one-by-one, until I realised that only a single trace was required to make the problem go away. My logic now would tell me that I was dealing with some sort of race-condition or timing related issue that the trace just "hid under the rug". But I checked in the code with the following line, and all was well: printf(""); Which hacks are you ashamed of?

Wrong getBounds() on LineScaleMode.NONE

- by ghalex

I have write a simple example that adds a canvas and draw a rectangle with stroke size 20 scale mode none. The problem is that if I call getBounds() first time I will get a correct result but after I call scale(); the getBounds() function will give me a wrong result. It will take in cosideration the stroke but stroke has scalemode to none and on the screen nothing happens but in the result I will have a x value smaller. Can sombody tell me how can I fix this ? protected var display :Canvas; protected function addCanvas():void { display = new Canvas(); display.x = display.y = 50; display.width = 100; display.height = 100; display.graphics.clear(); display.graphics.lineStyle( 20, 0x000000, 0.5, true, LineScaleMode.NONE ); display.graphics.beginFill( 0xff0000, 1 ); display.graphics.drawRect(0, 0, 100, 100); display.graphics.endFill(); area.addChild( display ); traceBounce(); } protected function scale():void { var m :Matrix = display.transform.matrix; var apply :Matrix = new Matrix(); apply.scale( 2, 1 ); apply.concat( m ); display.transform.matrix = apply; traceBounce(); } protected function traceBounce():void { trace( display.getBounds( this ) ); }

Use of clone() and appendTo() with draggable - unexpected results with dragging

- by Matt Gutting

I'm constructing a UI for a doctor scheduling app. We have several doctors, each of whom can go in one of several locations on a scheduled day (M - F). I have the main day/location grid (table) in the center of the screen. At the left is a table for the doctor names. On loading, each table cell contains a span (outlined) with the doctor name. The doctor name can go in one slot for each day. I didn't want to just put 5 copies of the doctor name, because the doctor might not be available all 5 days of the week. The idea was: Drag the span and drop into the calendar table. On the drag "start" event, clone the span and append it to the table cell. Now there is another span ready to be dropped into the calendar table. One line of code does the work: $(ui.helper).clone(true).prependTo(ui.helper.parent()); This works. But when I move the cloned span, the original one moves in sync - preserving the spatial relationships as I move the clone around (no doubt there's a "position:relative;left=XX;top=YY" inserted somewhere). I'm sure there's a way to do what I'm thinking of, while keeping the two spans independent. But I'm not thinking of one. Does anyone have an idea? Thanks! Matt I posted this identical question to the jQuery forum as well.

Obtaining touch location for a uiscrollview touch

- by LOSnively

I have a uiscrollview as an element of a uiscrollviewcontroller, along with other view objects. The image scrolls and zooms as expected, when the scrollView is the top subview. However, I also need to get the screen location of the touch, in particular when there is no scroll action. (I understand the location may change during a scroll, but that's not important.) I haven't found a way to do that. In the scrollviewcontroller implementation I have customized all of the standard methods that should do this: "touchesShouldBegin...", "touchesBegan:...", "touchesEnded:...", and so on. As far as I can tell, none of these are being called during a touch event when the scrollView is the top subview. I've tried setting the delayContentTouches property to both YES and NO, and that doesn't seem to make a difference. As an alternative, I've tried putting a UIView as the top subview and then tried passing the touches to the now underlying scrollView. In this configuration, the standard methods are called and I can get the touch location, but I haven't found a mechanism for the touches to be passed to the scrollView so scrolling occurs. Doing something like sending the touch messages to the specific scrollView, or to "super" or just sending them to nextResponder doesn't do it. It seems I can make the scroll work or find the location of the touch but not both, depending on what the "top" subview is. I suspect this is trivial, but after two weeks of struggling, it's time to eat my embarrassment for not being able to do this seemingly simplest of things. I've read all of the related questions here on stackoverflow, tried most if not all of the suggestions, and so far, nothing has worked. I've looked through the various links and references suggested by the answers, including Apple's documentation, but none have pointed out the gap in my understanding. Any ideas would be appreciated.

kohana project structure

- by user176217

Hello Guys. I'm investigating using Kohana for my next project. The site will consist of user registration (and hence user profiles) where users will have certain privileges. The site will also have an admin section where administrators can go to say block a user or delete a post or look at usage statistics for example. A good comparison site would be a multi-user blog, where each blogger depending on her/his permissions can post/edit/delete blogs...just as an example. Firstly, I'm not sure about how to set up the controller/view structure in order to separate the admin section from the front facing site. I'm using Kohana 3, so I was thinking of a controller structure like so: application/classes/controller/front (front facing)...and application/classes/controller/admin (for administrative section). Or I notice you may be able to use the Route class to set up routes, so I could set up an "admin" route. for example: www.example.com/admin will lead to the admin logon screen. www.example.com --- front controller. As well, can I somehow separate the "Admin" views and controllers from the "front facing" views and controllers like divide them up based on folder structure? Any help is very much appreciated. Thank you.

How does the overall view hierarchy change when using UIKit view manipulations?

- by executor21

I've been trying to figure out what happens in the view hierarchy when methods like pushViewController:animated, presentModalViewController:animated, and tab switches in UITabBarViewController are used, as well as UIAlertView and UIActionSheet. (Side note: I'm doing this because I need to know whether a specific UIView of my creation is visible on screen when I do not know anything about how it or its superview may have been added to the view hierarchy. If someone knows a good way to determine this, I'd welcome the knowledge.) To figure it out, I've been logging out the hierarchy of [[UIApplication sharedApplication] keyWindow] subviews in different circumstances. Is the following correct: When a new viewController is pushed onto the stack of a UINavigationController, the old viewController's view is no longer in the view hierarchy. That is, only the top view controller's view is a subview of UINavigationController's view (according to logs, it's actually several private classes such as UILayoutContainerView). Are the views of view controllers below the top controller of the stack actually removed from the window? A very similar thing happens when a new viewController is presented via presentModalViewController:animated. The new viewController's view is the only subview of the kew window. Is this correct? The easiest thing to understand: a UIAlertView creates its own window and makes it key. The strangest thing I encountered: a UIActionSheet is shown via showInView: method, the actionSheet isn't in the view hierarchy at all. It's not a subview of the view passed as an argument to showInView:, it isn't added as a subview of the key window, and it doesn't create its own window. How does it appear, then? I haven't tried this yet, so I'd like to know what happens in the keyWindow hierarchy when tabs in a UITabBarController are switched. Is the view of the selected UIViewController moved to the top, or does it work like with pushViewController:animated and presentModalViewController:animated, where only the displayed view is in the window hierarchy?

PDO bindparam not working.

- by jim

I am trying to save data into a database using PDO. All columns save correctly with the exception of one. No matter what I try, I cannot get the data to go in. myfunc($db, $data) { echo $data; // <----- Outputs my data. example: 'jim jones' $stmt = $db->prepare("CALL test(:id, :data, :ip, :expires)"); $stmt->bindParam(':id', $id, PDO::PARAM_STR); $stmt->bindParam(':data', $data, PDO::PARAM_STR); $stmt->bindParam(':ip', $ip, PDO::PARAM_STR); $stmt->bindParam(':expires', $expires, PDO::PARAM_STR); ... } So even after verifying that the data variable in fact holds my data, the bindParam method will not bind. When I echo the data variable, I can see the data is there. It will not save though. If I copy the echo'd output of the data variable to screen and paste it into a new variable, it WILL save. I'm at this now for a couple of hours. Can someone please have a look? EDIT: I want to also mention that I have tried using bindValue() in place of bindParam() and the data for the data variable will still not save.

Creating content for rails-based applications

- by Matthias Hryniszak

Hi, I'm facing a problem of cleaning up my application in Ruby on Rails. What I have is a pretty standard 3-panel, header and footer layout where different parts of the screen contain different functionality. By that I mean for example that the header contains (among others) a select that allows one to select parts of the application and a context-dependent menu. The main content area contains obviously the most interactive stuff whereas side panels contain quick-links with stuff like shopping-cart preview, list of potentially attractive products for the customer, a selector to narrow down the list of options... I was wondering how do I go about simplifying the design. Right now I have the stuff that provides data for the "common" stuff (as opposed to direct content that's placed in the center) called from all the actions (with a filter) but that doesn't feel right for me. I've read that "components" are also not the way to go for obvious performance reasons. Is there something that's more like component-oriented (other frameworks do have that kind of stuff - Grails: <ui:include ../>, ASP.NET MVC: <% Html.RenderAction() %>)? Best regards, Matthias.

How Do I Make A Small jQuery Confirm Replacement?

- by Volomike

I have a table row with a Delete link on it for deleting that row. I want to create a jQuery feature that pops up above that Delete link an "Are you sure?" yes/no confirm dialog, but in a very small size. How do I achieve this in the least lines of code in jQuery? I mean, I need to determine the x,y of the Delete link that was detected from a click, and then move (and fadeIn()) a DIV into that location. If they click anywhere on that page except Yes on the yes/no, the thing does a fadeOut(). If they click Yes, then it deletes the row with a fadeOut() effect. Note on this I don't need a modal screen dimmer, but the confirm needs to work modally. (Items above that are bolded are something I don't exactly know how to do. Items bolded and italicized are important to what I need to do.) I would think a widget like this would be critical to any Web 2.0 design, much like the Pines Notify feature seems essential.

Issue with Facebook JS API, revokeAuthorization

- by BBonifield

I am trying to integrate FB connect into our user profile screen. Although, I'm having an issue with FB.ApiClient.revokeAuthorization. http://pastie.org/921942 The basic problem is that I revoke the auth at line 44 after the user clicks the disconnect button. After that, all subsequent API calls don't have a valid session to even check user status. I've tried wrapping blocks in a FB.Connect.forceSessionRefresh block, but then the code will never be called at all. I'm not sure what the proper workflow should be for this purpose. Right now it's basically... User arrives at profile NOT connected to the application. User clicks on the connect button. Once connected, DOM manipulation occurs to hide the connect button and add in a disconnect button. User clicks on the disconnect button. User's authorization to the application is revoked and (it seems) the API session to the FB server is invalidated. DOM manipulation occurs to hide the disconnect button and readd the connect button. User clicks on the connect button. Once connected, the FB.Connect.get_loggedInUser() don't return the actual user.

Progressive MP4 video issues in Flash- Video stops rendering

- by Conor

I'm currently working on a flash project that has an intro video that plays before heading into the main app. This video is an H.264 .mp4, 1550x540, and around 10MB. The problem thats currently driving me insane is that when I test it, occasionally the video will begin playing, and then suddenly stop rendering the video frames, leaving the audio playing in the background with nothing on screen. Once the file is played through fully (based on listening to the audio), my playback complete event fires like it should, but I can't find any info of people having similar issues. Attached is a trace of the .mp4 metadata in case that helps. videoframerate : 24 audiochannels : 2 audiocodecid : mp4a audiosamplerate : 48000 trackinfo: 0: length : 608000 timescale : 24000 language : eng sampledescription: 0: sampletype : avc1 1: length : 1218560 timescale : 48000 language : eng sampledescription: 0: sampletype : mp4a duration : 25.386666666666667 width : 1540 videocodecid : avc1 seekpoints: 0: time : 0 offset : 13964 1: time : 0.333 offset : 16893 2: time : 0.667 offset : 34212 ... 73: time : 24.333 offset : 9770329 74: time : 24.667 offset : 9845709 75: time : 25 offset : 9895215 moovposition : 32 height : 540 avcprofile : 77 avclevel : 51 aacaot : 2 This has been driving me absolutely insane... any help would be much appreciated!

Cakephp ACL authentication issue - I'm locked out

- by Baseer

I've followed the CakePHP Cookbook ACL tutorial And as of right now I'm just trying to add users using the scaffolding method. I'm trying to go to /users/add but it always redirects me to the login screen even though I have added $this->Auth->allow('*'); in beforeFilter() temporarily to allow access to all pages. I've done this in both the UsersController and GroupsController as the tutorial asked. Below is my code for UsersController which I think will be the most relevant of all the files. Let me know if any other piece of code is required. <?php class UsersController extends AppController { var $name = 'Users'; var $scaffold; function beforeFilter() { parent::beforeFilter(); $this->Auth->allow('*'); } function login() { //Auth Magic } function logout() { //Leave empty for now. } } ?> I think I've pretty much followed the tutorial, any ideas as to what I may be missing? Thanks. I've been stuck on this for a while. =(

ASP.NET webservice API security.

- by Tejaswi Yerukalapudi

Hi, I have an iPhone app accessing an ASP.NET Webservice for data. Since I'm building both the ASP.NET end and the iPhone part of the app, and we'll shortly be publishing it in the Appstore, I'd like to know what security checks I need to make. The basic flow of the program (without divulging too much info about it) is as follows - . Login (Enter Username, pass on the app) . Primary screen where the data is loaded from a webservice and presented . And post data back after a few updates by the user I'm using POST to send the data to the Webservice via HTTPS. I'm sanitizing the inputs, checking for length of the inputs, but that's the limit of my knowledge as far as security goes. Any other tips are greatly appreciated! Edit: I should probably add that our service needs to be subscribed to separately and the iPhone component of it cannot be used alone. So the average user will not have login credentials. And the app itself has healthcare data in it, so I'd rather not have anyone trying attacks from my login page. Thanks, Teja.

HTML Doctype Setting / IE Quirks Mode

- by Frederico

I'm working within the parameters of an un-reachable developer, whom has created an html generation system for our products.. Whenever a new page is generated he places:   resulting in my code looking like:   <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html lang="en" xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> I don't believe IE read's this doctype at all, as when looking at the developer screen, it renders in Quirks mode... is there any other way to force IE out of this horrible Quirks mode? I've been trying to reach the developer but he has been rather un-available.. Thank you in advance for any help you might have to offer.

Placement/Positioning/Alignment of UIScrollView w.r.t. length of Title NSString

- by Shoaibi

I have a scenario where i show stuff like: ----------------------------------- titleview (UITextView) ______________ tArea (UIScrollView) ttextview (UITextView) ----------------------------------- Now here is the condition: Length of titleview's text is dynamic, varies based on user input. Because of the condition I have trouble placing tArea e.g. UIScrollView on the screen, it either appears way too below than the titleview, or overlaps it. Previously what i did: Count the number of characters in titleview.text.length and divide them by 27 (e.g. characters in one line when using boldSystemFontOfSize:20) and multiply by 10 to get the starting X of tArea e.g. UIScrollView. But that sucked. Because i had to duplicate code for rotation to landscape. What do i have now? : CGSize titlesize = [title sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 90) lineBreakMode:UILineBreakModeWordWrap]; ttitleview = [[UITextView alloc] initWithFrame:CGRectMake(5, 5, 310,titlesize.height)]; ttitleview.text = title; ttitleview.font = [UIFont boldSystemFontOfSize:20]; ttitleview.backgroundColor = [UIColor clearColor]; ttitleview.editable = NO; [self.view addSubview:ttitleview]; CGSize textsize = [ttext sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 350) lineBreakMode:UILineBreakModeWordWrap]; tArea = [[UIScrollView alloc] initWithFrame:CGRectMake(5, titlesize.height, 310, 230)]; tArea.contentSize = CGSizeMake(310, textsize.height+20); tArea.pagingEnabled = FALSE; tArea.scrollEnabled = TRUE; tArea.backgroundColor = [UIColor clearColor]; [self.view addSubview:tArea]; ttextview = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 310, textsize.height + 20)]; ttextview.text = ttext; ttextview.font = [UIFont systemFontOfSize:20]; ttextview.backgroundColor = [UIColor clearColor]; ttextview.editable = NO; [tArea addSubview:ttextview]; But its no use. Looking for an elegant solution than this.

Updating multiple divs w/ RJS/AJAX

- by bgadoci

I am successfully using RJS to implement AJAX on a page.replace.html create.js.rjs. I am attempting to update two locations instead of one and after watching Ryan Bates Railscast I am very close (I think) but have a problem in the syntax of my /views/likes/create.js.rjs file. Here is the situation: located at /views/likes/create.js.rjs is the following code: page.replace_html "votes_#{ @site.id }", :partial => @like page.replace_html "counter", 10 - (@question.likes.count :conditions => {:user_id => current_user.id}) page[@like].visual_effect :highlight My problem lies in the second line. The div "counter" displays the following code in the /views/question/show.html.erb page: <div id="counter"> You have <%= 10 - (@question.likes.count :conditions => {:user_id => current_user.id}) %> votes remaining for this question </div> From watching the screen cast I believe that my error has to do w/ the syntax of the second line. Specifically he mentions that you cannot use a local instance variable but not sure how to make the change. Thoughts?

How to setup OpenGL camera for a racing game

- by vian

I need the view to show the road polygon (a rectangle 3.f * 100.f) with a vanishing point for a road being at 3/4 height of the viewport and the nearest road edge as a viewport's bottom side. See Crazy Taxi game for an example of what I wish to do. I'm using iPhone SDK 3.1.2 default OpenGL ES project template. I setup the projection matrix as follows: glMatrixMode(GL_PROJECTION); glLoadIdentity(); glFrustumf(-2.25f, 2.25f, -1.5f, 1.5f, 0.1f, 1000.0f); Then I use glRotatef to adjust for landscape mode and setup camera. glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glRotatef(-90, 0.0f, 0.0f, 1.0f); const float cameraAngle = 45.0f * M_PI / 180.0f; gluLookAt(0.0f, 2.0f, 0.0f, 0.0f, 0.0f, 100.0f, 0.0f, cos(cameraAngle), sin(cameraAngle)); My road polygon triangle strip is like this: static const GLfloat roadVertices[] = { -1.5f, 0.0f, 0.0f, 1.5f, 0.0f, 0.0f, -1.5f, 0.0f, 100.0f, 1.5f, 0.0f, 100.0f, }; And I can't seem to find the right parameters for gluLookAt. My vanishing point is always at the center of the screen.

Best way to display a "High Scores" Results

First, I would to thank everyone for all the help they provide via this website. It has gotten me to the point of almost being able to release my first iPhone app! Okay, so the last part I have is this: I have a game that allows users to save their high scores. I update a plist file which contains the users Name, Level, and score. Now I want to create a screen that will display the top 20 high scores. What would be the best way to do this? At first I thought possibly creating an HTML file with this info but am not even sure if that is possible. I would need to read the plist file, and then write it out as HTML. Is this possible? To write a file out as HTML? Or an even better question, is there a better way? Thanks in advance for any and all help! Geo...

I'm new to JQuery -- not new to javascript. Was able to open the OSX STYLE DIALOG using the hyperlink button provided in the demo index.html page, but would like to open it on the page load. I read a couple links on StackOverflow (http://stackoverflow.com/questions/1611727/how-do-i-invoke-a-simplemodal-osx-dialog-on-page-load), but still could not get it to work in the exact same index.html page. I finally resorted to a stopgap measure by programmatically invoking the button click of a hidden button element -- see following fragment: onLoad="document.getElementById('load_OSX_Example').click();"> <input type="hidden" id="load_OSX_Example" value="" class='osx'> <script type="text/javascript" language="javascript"> //#### open the OSX Modal ########## $(document).ready(function(){ $("#osx-modal-content").modal(); }); </script> So I have two questions: How can you invoke the class='osx' using javascript/html programmatically? Why won't this work using the $("#osx-modal-content").modal(); call in javascript (see fragment above)? I tried this in multiple browsers, and the only content that displayed on the screen was content of this tag: "div id="osx-modal-title", and there was no error in the jscript console.

How to make a small flash swf with ComboBox in Actionscript 3?

- by Sint

I have a pure Actionscript 3 project, using flash.* libraries, compiles down to about 6k (using mxmlc). Program handles about 1k shapes, a few sprites, a sockets connection, works great (tastes less filling). Now, how would I add a ComboBox control without incurring excessive bloat? More specificially, I would like to keep the size under 100k. So far I have tried: Adobe mx.controls ComboBoxexample - simple mxml example compiles to 200+k both on my main Linux Box using mxmlc and in Windows using Flash Builder 4 Yahoo Astra - uses mx libraries underneath(so as bloated as Adobe?), plus does not contain exact ComboBox Keith Peter's MinimalComps - seems small, but far from providing ComboBox functionality SPAS (Swing Package for Actionscript) - compiles to 130k, but alpha version of ComboBox does not let me adjust height... asuilib - compiles to 40k, unfortunately this ComboBox does not provide for scrolling items...if it does not fit on screen no way to scroll to it Now my questions: Is there a way to lower size for projects importing mx.controls ? Maybe there is a way to fix SPAS or asuilib ComboBoxes? Perhaps, there are some other libraries which provide a ComboBox(or DropList)?

Create a menu in a perspective in Eclipse

- by Krt_Malta

Hi. I am developing an Eclipse plug-in and I'd like to associate a new menu (at the top of the screen along with File, Edit etc) with a perspective I'm creating. I did the menu ok but it is being displayed even in other perspectives. How can I associate it only with my perspective? This is the code I am using in plugin.xml: <plugin> <extension point="org.eclipse.ui.perspectives"> <perspective class="org.eclipse.ui.articles.perspective.API_Development" id="org.eclipse.ui.articles.perspective.API_Development" name="API Development"> </perspective> </extension> <extension point="org.eclipse.ui.actionSets"> <actionSet label="Sample Action Set" visible="true" id="API_Development_Menu.actionSet"> <menu label="API Development" id="sampleMenu"> <separator name="sampleGroup"> </separator> </menu> </actionSet> </extension> </plugin> Thanks and regards, Kurt
