• Is the Windows dev environment worth the cost?

  - by MCS

  I recently made the move from Linux development to Windows development. And as much of a Linux enthusiast that I am, I have to say - C# is a beautiful language, Visual Studio is terrific, and now that I've bought myself a trackball my wrist has stopped hurting from using the mouse so much. But there's one thing I can't get past: the cost. Windows 7, Visual Studio, SQL Server, Expression Blend, ViEmu, Telerik, MSDN - we're talking thousands for each developer on the project! You're definitely getting something for your money - my question is, is it worth it? [Not every developer needs all the aforementioned tools - but have you ever heard of anyone writing C# code without Visual Studio? I've worked on pretty large software projects in Linux without having to pay for any development tool whatsoever.] Now obviously, if you're already a Windows shop, it doesn't pay to retrain all your developers. And if you're looking to develop a Windows desktop app, you just can't do that in Linux. But if you were starting a new web application project and could hire developers who are experts in whatever languages you want, would you still choose Windows as your development platform despite the high cost? And if yes, why?

• Cursor on Path doesn't appear in SilverLight

  - by Rahul Soni

  I am trying to draw a circle with a glass effect using Alpha. I am successful in creating that by using the below XAML. The cursor changes to Hand for the Ellipses, but it doesn't affect Path. Basically, I want to show "hand" cursor wherever the mouse appears over the circle. I hope this is not a known issue and I am missing something small. Any help is really appreciated. <Ellipse Cursor="Hand" Width="200" Height="200" Fill="#C42222" Canvas.Left="0" Canvas.Top="0" /> <Ellipse Cursor="Hand" Width="200" Height="200" Canvas.Left="0" Canvas.Top="0"> <Ellipse.Fill> <RadialGradientBrush GradientOrigin="0.3,0.7"> <GradientStop Offset="0" Color="#00000000" /> <GradientStop Offset="1" Color="#66000000" /> </RadialGradientBrush> </Ellipse.Fill> </Ellipse> <Path Cursor="Hand" Stretch="Fill" Height="114.598" Width="198.696" Data="M98.388435,-1.3301961 C98.388435,-1.3301961 117.1151,-3.094949 141.69321,8.1370029 C156.42262,14.868201 167.67375,23.694145 175.66234,33.657074 C183.67349,43.648144 181.90166,37.8708 191.90166,58.8708 C201.90166,79.870796 199.16658,89.212738 199.13568,92.90377 C198.77556,135.92146 175.45959,97.59124 156.75465,81.024025 C140.98892,67.060104 117.41241,64.357407 114.41241,64.357407 C111.4124,64.357407 83.061241,60.114159 63.061195,71.114143 C43.061146,82.114136 39.637829,86.429352 22.999804,100.99996 C6.5005584,115.44904 2.9997537,112.99996 2.9997537,112.99996 C2.9997537,112.99996 -1.1832786,97.194221 1.9997513,81.999893 C7.2054667,57.150185 13.999762,47.999939 17.999771,42.999943 C21.999781,37.99995 29.935833,23.400871 54.053131,10.21261 C78.91642,-3.3835876 98.388435,-1.3301961 98.388435,-1.3301961 z"> <Path.Fill> <LinearGradientBrush EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="#55FFFFFF" Offset="0"/> <GradientStop Color="#11FFFFFF" Offset="0.5"/> <GradientStop Color="#00FFFFFF" Offset="1"/> </LinearGradientBrush> </Path.Fill> </Path>

• Preventing a button from responding to 'Enter' in ASP.net

  - by kd7iwp

  I have a master template that all the pages on my site use. In the template there is an empty panel. In the code-behind for the page an imagebutton is created in the panel dynamically in my Page_Load section (makes a call to the DB to determine which button should appear via my controller). On some pages that use this template and have forms on them, pressing the Enter key fires the click event on this imagebutton rather than the submit button in the form. Is there a simple way to prevent the imagebutton click event from firing unless it's clicked by the mouse? I'm thinking a javascript method is a hack, especially since the button doesn't even exist in the master template until the button is dynamically created on Page_Load (this is ugly since I can't simply do <% =btnName.ClientId %> to refer to the button's name in my aspx page). I tried setting a super-high tabindex for the image button and that did nothing. Also set the button to be the DefaultButton in its panel on the master template but that did not work either.

• Google Maps: How does Trulia create their custom InfoWIndows?

  - by NickT

  I really like how Trulia.com has created their custom Google Map InfoWindows. What I like in particular about Trulia's implementation of the InfoWindow is: Extends beyond the map border: Google Maps InfoWindows are contained within the map border whereas Trulia's seems to be able to float on-top of the map Always displays InfoWindow near map Center: Google Maps InfoWindows always display the InfoWindow above the marker whereas Trulia InfoWindows always display the InfoWindow as close the center of the map as possible. For example, if the map marker icon is on the top of the map near the border, the Trulia InfoWindow is displayed below the map marker icon InfoWindow is displayed on mouse hover (not 'click'): With the default Google Maps InfoWindow, you have to 'click' the map marker icon to display the InfoWindow whereas Trulia InfoWindows are display simply by hovering over the map marker icon. I found the PdMarker, which is a 3rd party extension for Google Map InfoWindows that accomplishes most of the above bullets but not all. 1) It does not extend beyond the map border, 2) it does not work with Google Maps API version 3 (only version 2). Anyone know how Trulia is accomplishing their InfoWindow-like implementation on Google Maps API v3?

• Delphi App has "No Debug Info" when Debugging

  - by James L.

  We have built an application that uses packages and components. When we debug the application, the "Event Log" in the IDE often shows the our BPLs are being loaded without debug information ("No Debug Info"). This doesn't make sense because all our packages and EXEs are built with debug. _(each project) | Options | Compiling_ [ x ] Assertions [ x ] Debug information [ x ] Local symbols Symbol reference info = "Reference info" [ ] Use debug .dcus [ x ] Use imported data references _(each project) | Options | Linking_ [ x ] Debug information Map file = Detailed We have 4 projects, all built with runtime pacakges: Core.bpl Components.bpl Plugin.bpl (uses both #1 & #2) MainApp.exe (uses #1) Problems Observed 1) Many times when we debug, the Components.bpl is loaded with debug info, but all values in the "Local Variables" window are blank. If you hover your mouse over a variable in the code, there is no popup, and Evaluate window also shows nothing (the "Result" pane is always blank). 2) Sometimes the Event Log shows "No Debug Info" for various BPLs. For instance, if we activate the Plugin.bpl project and set it's Run | Parameter's Host Application to be the MainApp.exe, and then press F9, all modules seems to load with "Has Debug Info" except for the Plugin.bpl module. When it loads, the Event Log shows "No Debug Info". However, if we close the app and immediately press F9, it will run it again without recompiling anything and this time Plugin.bpl is loaded with debug ("Has Debug Info"). Questions 1) What would cause the "Local Variables" window to not display the values? 2) Why are BPLs sometimes loaded without debug info when the BPL was complied with debug and all the debug files (dcu, map, etc.) are available?

• Customize jQuery.aptags plugin - mouseclick submit from .ac_results list

  - by atmorell

  Hello, I am using jquery.autocomplete.js and jquery.apitags to select a few elements from a div (.ac_results) This works great, and I can select multiple elements etc. However the jquery-aptags plugin does only fire when enter is pressed. This might confuse some users if they use the mouse to click instead of the arrows/enter on the keyboard. I think this is the code inside jquery.aptags that submits the tag. // // Hook to the keypress event. // $(this).bind('keypress', { __c: __c }, function (e) { var c = ''; var i = 0; var v = $(this).val(); if (e.keyCode == 13) { e.stopPropagation(); e.preventDefault(); __createSpans(this, v, e.data.__c, true); } }); I am wondering if it is possible to call the method directly from a new event. $('.ac_results > ul > li').livequery(function() { $(this).bind('click', function() { $('#address_city'). //how do I fire the "enter" event from here? }); }); Any thoughts?

• 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!

• Paddle Movement using Box2D

  - by Anubhav Sharma

  Hello everybody, I'm making a game like Arkanoid and to move the ship with mouse, I'm using the following code : var mousex:int = costume.stage.mouseX; if (mousex < paddleWidth/2) mousex = paddleWidth/2; else if (mousex > PhysiVals.STAGE_WIDTH - paddleWidth/2) mousex = PhysiVals.STAGE_WIDTH - paddleWidth / 2; var idealLocation:Point = new Point(mousex, ypos); var directionToTravel:b2Vec2 = new b2Vec2((idealLocation.x -> costume.x) * PhysiVals.paddleSpeed, idealLocation.y-costume.y); directionToTravel.Multiply(1 / PhysiVals.RATIO); directionToTravel.Multiply(30); body.SetLinearVelocity(directionToTravel); Everything's going fine there! The paddle is moving the way it should! The problem is I want a little inclination towards the direction its moving and when it stops moving the angle of inclination should become zero. I tried playing with the angular velocity but I have no real idea how to do this! So Please help!

• Can iPad/iPhone Touch Points be Wrong Due to Calibration?

  - by Kristopher Johnson

  I have an iPad application that uses the whole screen (that is, UIStatusBarHidden is set true in the Info.plist file). The main window's frame is set to (0, 0, 768, 1024), as is the main view in that frame. The main view has multitouch enabled. The view has code to handle touches: - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { for (UITouch *touch in touches) { CGPoint location = [touch locationInView:nil]; NSLog(@"touchesMoved at location %@", NSStringFromCGPoint(location)); } } When I run the app in the simulator, it works pretty much as expected. As I move the mouse from one edge of the screen to the other, reported X values go from 0 to 767. Reported Y values go from 20 to 1023, but it is a known issue that the simulator doesn't report touches in the top 20 pixels of the screen, even when there is no status bar. Here's what's weird: When I run the app on an actual iPad, the X values go from 0 to 767 as expected, but reported Y values go from -6 to 1017. The fact that it seems to work properly on the simulator leads me to suspect that real devices' touchscreens are not perfectly calibrated, and mine is simply reporting values six pixels too low. Can anyone verify that this is the case? Otherwise, is there anything else that could account for the Y values being six pixels off from what I expect? (In a few days, I should have a second iPad, so I can test this with another device and compare the results.)

• Mac vs. Windows Browser Font Height Rendering Issue

  - by cdmckay

  I'm using a custom font and the @font-face tag. In Windows, everything looks great, regardless of whether it's Firefox, Chrome, or IE. On Mac, it's a different story. For some reason, the Mac font renderer thinks the font is a lot shorter than it is. For example, consider this test code (live example here): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Webble</title> <style type="text/css"> @font-face { font-family: "Bubbleboy 2"; src: url("bubbleboy-2.ttf") format('truetype'); } body { font-family: "Bubbleboy 2"; font-size: 30px; } div { background-color: maroon; color: yellow; height: 100px; line-height: 100px; } </style> </head> <body> <div>The quick brown fox jumped over the lazy dog.</div> </body> </html> Open it on Windows Firefox and on Mac Firefox. Use your mouse to select it. On Windows, you'll notice it fully selects the font. On Mac, it only selects about half the font. If you look at what it is selecting, you'll see that that part has been centered, instead of the full height of the font. Is there anyway to fix this rather large discrepancy?

• Crosshairs in Java

  - by typoknig

  I am making a game that needs a crosshair. I have been playing with the java.awt.cursor class and that is easy enough, but the problem is that I do not want the crosshairs to be able to leave the window I create for my game, so I tried this instead: private void drawCrossHair(Graphics g){ Ellipse2D ellipse = new Ellipse2D.Float(); ellipse.setFrame(crossHair.x, crossHair.y, 36, 36); Color yellow = new Color (0xEDFF62); g.setColor(yellow); g.fillOval(crossHair.x, crossHair.y, 40, 40); g.setClip(ellipse); g.clip(ellipse); Basically I am trying to remove the "ellipse" from "g" leaving only a small ring behind. The problem here is that "g.clip(ellipse);" gives me an error. My objective with this code is to create a circle with a transparent center, like a donut. Once the donut is created I will add some small points on the inside of it so it looks more like crosshairs. One thing that may or may not be an issue is that I plan on moving the crosshairs with a joystick, not a mouse... I do not know if that will limit my options for what kind of object my crosshairs can be.

• jquery toggle on hover for multiple divs

  - by Oterox

  I have some divs with identical structure and i want to toggle when the mouse hovers the div so a hides and b shows: <ul class="tweets"> <li> <div class="a"> <p>show a</p> </div> <div class="b"> <p>show b</p> </div> </li> <li> <div class="a"> <p>show a</p> </div> <div class="b"> <p>show b</p> </div> </li> <li> <div class="a"> <p>show a</p> </div> <div class="b"> <p>show b</p> </div> </li> </ul> This is the jquery i'm using: $(document).ready(function(){ var tweet = $("ul.tweets .a"); tweet.hover(function(){ $('.a').toggle(); $('.b').toggle(); }); }); But this toggles ALL the divs and i only need to toggle one.I should use $(this) but i don't know how.How could i make this work?

• How can I distinguish between overlapping segments of text using HTML?

  - by Siracuse

  Easy question, it is valid to have overlapping spans in html? Example: <span id="1">This is <span id="2"> some text </span> some other text </span> ^ ^ End1 End2 Edit: I see now that the spans closing tag would be ambiguous about which one it is closing, and that first </span> would close span id = 2, not 1 like I intended. My problem is, I have a block of text which I'm trying to highlight based on what the mouse hovers over. This block of text is composed of sections, some of which "overlap" eachother. I'm trying to use some jQuery and HTML to present this document so when I hover over the sections, the appropriate one will be highlighted. So, in my example above, the first span is meant to be ended with the first span close tag, and the second span is meant to be ended to with the second span close tag. This is because of the semantics of my document, these are two overlapping segments. I want it so when I hover to the left, it will only highlight up to span id = 1 and the first span close, if I hover between the two "overlapping" spans, it will highlight both of them, and if I hover to the right, it will highlight from span id=2 to the last span close. However, I'm starting to think this isn't possible. Is there any way I can distinguish segments of text in HTML that allows overlapping? So my jQuery script that highlights when I hover over different spans will highlight the correct portions. Should I alternate between div's and spans? Would that disambiguate what I'm closing then and allow me the do the proper highlighting with my jQuery hover script? I'm wondering about more than 2 segments overlapping now. Sigh, I wish I could just be explicate about what I'm closing.

• Detecting whether user stayed after prompting onBeforeUnload

  - by Daniel Magliola

  In a web app I'm working on, I'm capturing onBeforeUnload to ask the user whether he really wants to exit. Now, if he decides to stay, there are a number of things I'd like to do. What I'm trying to figure out is that he actually chose to stay. I can of course declare a SetTimeout for "x" seconds, and if that fires, then it would mean the user is still there (because we didn't get unloaded). The problem is that the user can take any time to decide whether to stay or not... I was first hoping that while the dialog was showing, SetTimeout calls would not fire, so I could set a timeout for a short time and it'd only fire if the user chose to stay. However, timeouts do fire while the dialog is shown, so that doesn't work. Another idea I tried is capturing mouseMoves on the window/document. While the dialog is shown, mouseMoves indeed don't fire, except for one weird exception that really applies to my case, so that won't work either. Can anyone think of other way to do this? Thanks! (In case you're curious, the reason capturing mouseMove doesn't work is that I have an IFrame in my page, containing a site from another domain. If at the time of unloading the page, the focus is within the IFrame, while the dialog shows, then I get the MouseMove event firing ONCE when the mouse moves from inside the IFrame to the outside (at least in Firefox). That's probably a bug, but still, it's very likely that'll happen in our case, so I can't use this method).

• Jquery animate bottom problem

  - by andrea

  It's strange. I have an animation that start when i .hover on a DIV. Into this div i have another in position absolute that i want to move up until the mouse stay on main div and go down in your position when i go out of main div. A simple hover effect. I have write down this function that work well apart a strange bug. var inside = $('.inside') inside.hover(function() { $(this).children(".coll_base").stop().animate({ bottom:'+=30px' },"slow") }, function() { $(this).children(".coll_base").stop().animate({ bottom:'-=30px' },"slow"); }); i need +=30 and -=30 because i have to apply this function to a range of div with different bottom. The problem is that if i hover on and out of div the DIV animate right but when go down he decrease the value of bottom every animation. If i go up and down from the main div i see that the animated div go down even beyond the main div. I think that i miss something to resolve this bug. Thanks for any help

• Attaching an event to an Iframe that contains more iframes

  - by Oscar Godson

  I have an editor which is in my window that contains a wrapping iframe and then 2 more iframes inside like (the HTML inside the <iframe> element is inserted via write() in JS, not hardcoded like this): <iframe class="parent"> <div class="wrapper"> <iframe class="editor"></iframe> <iframe class="previewer"></iframe> </div> </iframe> One is an editor, the other is a previewer. The first one that contains the two (we'll call this the parent) has an eventListener for mousemove attached to it, but nothing is firing. If i add a 5px border for example, the event will fire when I move my mouse on the border of the parent, but not when i hover over the middle which contains the editor or previewer (previewer is display:none while the editor is visible, and vice versa). So, the blue area in the following i can mousemove, but the rest I can't. It's most likely because of the stacking order, but how can I attach an event to fire on the entire frame? I need mousemove because on mousemove I display a menu in the bottom right. I want the same menu to display whether or not the editor or the previewer is visible.

• Loading Native library to external Package in Eclipse not working. is it a Bug?

  - by TacB0sS

  I was about to report a but to Eclipse, but I was thinking to give this a chance here first: If I add an external package, the application cannot find the referenced native library, except in the case specified at the below: If my workspace consists of a single project, and I import an external package 'EX_package.jar' from a folder outside of the project folder, I can assign a folder to the native library location via: mouse over package - right click - properties - Native Library - Enter your folder. This does not work. In runtime the application does not load the library, System.mapLibraryName(Path) also does not work. Further more, if I create a User Library, and add the package to it and define a folder for the native library it still does not. If it works for you then I have a major bug since it does not work on my computer I test this in any combination I could think of, including adding the path to the windows PATH parameter, and so many other ways I can't even start to remember, nothing worked, I played with this for hours and had a colleague try to assist me, but we both came up empty. Further more, if I have a main project that is dependent on few other projects in my workspace, and they all need to use the same 'EX_package.jar' I MUST supply a HARD COPY INTO EACH OF THEM, it will ONLY (I can't stress the ONLYNESS, I got freaked out by this) work if I have a hard copy of the package in ALL of the project folders that the main project has a dependency on, and ONLY if I configure the Native path in each of them!! This also didn't do the trick. please tell me there is a solution to this, this drives me nuts... Thanks, Adam Zehavi.

• Migrate style from TabItem to TabHeader

  - by OffApps Cory

  Good day! I have a TabControl with TabItems that have been customized via a control template. This control template specifies a trigger whereby on mouseover, the content of tab header grows slightly. <ControlTemplate> <Storyboard x:Key="TabHeaderGrow"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="TabName" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.1000000" Value="1.1"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="TabName" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)"> <SplineDoubleKeyFrame KeyTime="00:00:00.1000000" Value="1.1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <ControlTemplate.Triggers> <EventTrigger RoutedEvent="Mouse.MouseEnter"> <BeginStoryboard Storyboard="{StaticResource TabHeaderGrow}"/> </EventTrigger> When I mouseover any of the tabs they work as expected, however the trigger also fires when I mouseover any of the elements in the tab body. I know that I need to migrate the control styling to a tabHeader controlTemplate, but I am unsure how to do that. I can't seem to do template binding for the content of the tabheader. Any help would be appreciated.

• How to make jquery hover event fire repeatedly.

  - by clinthorner

  I have a infinite carousel that I want to move when I hover over the next and previous buttons. Right now hover only fires this once. I want the carousel to continue moving while the mouse is within the next or previous buttons. Any Suggestions? jQuery.fn.carousel = function(previous, next, options){ var sliderList = jQuery(this).children()[0]; if (sliderList) { var increment = jQuery(sliderList).children().outerWidth("true"), elmnts = jQuery(sliderList).children(), numElmts = elmnts.length, sizeFirstElmnt = increment, shownInViewport = Math.round(jQuery(this).width() / sizeFirstElmnt), firstElementOnViewPort = 1, isAnimating = false; for (i = 0; i < shownInViewport; i++) { jQuery(sliderList).css('width',(numElmts+shownInViewport)*increment + increment + "px"); jQuery(sliderList).append(jQuery(elmnts[i]).clone()); } jQuery(previous).hover(function(event){ if (!isAnimating) { if (firstElementOnViewPort == 1) { jQuery(sliderList).css('left', "-" + numElmts * sizeFirstElmnt + "px"); firstElementOnViewPort = numElmts; } else { firstElementOnViewPort--; } jQuery(sliderList).animate({ left: "+=" + increment, y: 0, queue: true }, "swing", function(){isAnimating = false;}); isAnimating = true; } }); jQuery(next).hover(function(event){ if (!isAnimating) { if (firstElementOnViewPort > numElmts) { firstElementOnViewPort = 2; jQuery(sliderList).css('left', "0px"); } else { firstElementOnViewPort++; } jQuery(sliderList).animate({ left: "-=" + increment, y: 0, queue: true }, "swing", function(){isAnimating = false;}); isAnimating = true; } }); } };

I want it so when I hover to the left, it will only highlight up to span id = 1 and the first span close, if I hover between the two "overlapping" spans, it will highlight both of them, and if I hover to the right, it will highlight from span id=2 to the last span close. However, I'm starting to think this isn't possible. Is there any way I can distinguish segments of text in HTML that allows overlapping? So my jQuery script that highlights when I hover over different spans will highlight the correct portions. Should I alternate between div's and spans? Would that disambiguate what I'm closing then and allow me the do the proper highlighting with my jQuery hover script? I'm wondering about more than 2 segments overlapping now. Sigh, I wish I could just be explicate about what I'm closing.

• SWT TabFolder: Weird Drawing Behaviour

  - by JesperGJensen

  Hello StackOverflow Experts Description I have an SWT Page with a TabFolder with a number of dynamically created TabItems. On each TabItem i crate a Composite and set the TabItem.setControl() to the Composite. I then use this Composite as the page on which i draw my items. I draw a set of Controls, including Textbox's and Labels. For the First, Default Tab, this works fine. No problems. Problem On tabs that is not the first tab i have the following problems: I am unable to visually alter then Edited/Enabled state of my Controls. I am unable to visually set the Text content of my elements My Controls look disabled and have a Greyed out look. But i am able to Select the content with my mouse and use CTRL+C to copy it out. So the text contet is there and they are Editable. Visually it is just not updated. Any comments are appeciated, Any requests for code, examples will be supplied and help Welcommed. Updates I tried added the suggest debug loop to the code, where i attempt to enable my Controls. This was the result: [main] INFO [dk.viking.controller.LayerController] - f038.stklok is now Editable [true] and enabled [true] [main] INFO [dk.viking.controller.LayerController] - true Text {} [main] INFO [dk.viking.controller.LayerController] - true Composite {} [main] INFO [dk.viking.controller.LayerController] - true TabFolder {} [main] INFO [dk.viking.controller.LayerController] - true Shell {Viking GUI}

• Android Plugin in Eclipse 3.5 on Ubuntu 64bit got problems with properties

  - by Zordid

  Hi there! I got a huge problem with the Android Development Tools ADT running in Eclipse Galileo (3.5.1) on Ubuntu 9.10, 64bit. On this platform, I do not manage to see any property edit dialogs for layout properties. E.g. the one where you can select a string resource ID for text fields, or a drawable ID for image fields or backgrounds. Whenever I click on the ... button next to the property value - nothing happens, except this button disappears. Properties with a list of possible values, e.g. "wrap_content" or "fill_parent" are displayed in a dropdown box directly in the properties field. On a different system I work in a Windows environment with Eclipse 3.4 and the same ADT: no problems whatsoever, everything works fine, the dialogs come perfectly. Does anyone know what to do here? Where's the problem? Why does Eclipse not tell me that something goes wrong? Thanks! NEW DISCOVERIES: I found out that it might not even be an Android problem, but a general Eclipse problem that I can see with all version (Ganymede, Galileo, Helios) on my Linux (Ubuntu) system. It must be a simple UI problem: the button with ... next to the values does not receive the mouse click!! I managed to see the appropriate dialogs to edit the property values by doubleclicking the button - crazy, strange, ugly behavior! But why on earth does nobody else know about this problem - I cannot find anything else on the net about it! Could it be related to this strange "GDK native window problem" on Gnome? HELP!

• Tablet interface for the physically disabled?

  - by Glenn

  My sister has Cerebral Palsy, which in her case means she has only gross motor control and her speech is slurred. Implications should be obvious: traditional computer/phone/tablet interfaces won't work for her and she can't speak clearly enough for speech recognition software to help her at all. She enjoys reading but has difficulty holding the book and/or turning a page. There are a few options for helping her use a computer, but nothing for tablets or eReaders. That's where you come in. I would like to make (or buy, if such a thing exists) a better interface to an Android tablet that would work for someone with little to no physical dexterity or speech ability. I'd also be interested in work on the Kindle or iPad, but I'm most familiar with Android so I'm starting there. I know Android has Bluetooth capability. Is it possible to interface a joystick to control the Android device? By "control", I mean the entire operating system - selecting an app, launching it, controlling the menus, etc. I want to give her control over the whole thing, not just a specific app. On a PC this can be accomplished by creating a generic USB HID interface and an arcade joystick to move the mouse over the screen and click on thigns. Is it possible to do something like that in Android? Any help you can offer would be greatly appreciated. Thanks!

• How to implement escape Sequence in SDL

  - by Sa'me Smd

  Im trying to use the STL library inside the SDL. but it gives me the error "undeclared identifier" Is there any way i can use "\n"or even cout<<endl; Can the function SDL_WarpMousewhich places the mouse cursor on a desired location on screen help me with this. Because i want to put a tile on the next line sequence. I hope you get the Question. Its very vague and messed up question though (sorry for that). EDIT: void putMap(SDL_Surface* tile, SDL_Surface* screen) { for(int y = 0; y < 21; y++) { for(int x = 0; x < 60; x++) { if(maze[x][y] != '#') { apply_surface( x*10 , y*10 , tile, screen); } } cout<<endl; } } c:\documents and settings\administrator\my documents\visual studio 2008\projects\craptest\craptest\main.cpp(605) : error C2065: 'cout' : undeclared identifier c:\documents and settings\administrator\my documents\visual studio 2008\projects\craptest\craptest\main.cpp(605) : error C2065: 'endl' : undeclared identifier This is my apply_surface funtion. void apply_surface( int x, int y, SDL_Surface* source, SDL_Surface* destination ) { //Make a temporary rectangle to hold the offsets SDL_Rect offset; //Give the offsets to the rectangle offset.x = x; offset.y = y; //Blit the surface SDL_BlitSurface( source, NULL, destination, &offset ); }
