• Any screen capture software that captures webcam, microphone inputs too ?

  - by mohanr

  I am going to conduct a user study. Apart from capturing the screen while the user is interacting with the system, I also want to capture the video/audio of the user. Is there any software that in addition to capturing the screen also overlays it with the webcam/microphone inputs. The goal is to capture the complete experience of the user: key/mouse interactions with the system along with their facial/vocal responses. I know that I can maybe run a screen-capture software and also run a software for capturing webcam audio/video alongside and try to sync/overlay both these streams with timestamps. But I am going to be dealing with probably several hundred hours of data. So I am looking for a tool that can streamline the process for me amap and help me keep my sanity at end of the process. Thanks,

• OpenGL Wrapper in .Net

  - by Ngu Soon Hui

  This question is similar to the one here. But I feel that the answers recommended ( such as Tao and OpenTK) are not good enough because they are just a direct port from OpenGL, with no OOP design, and hard to use. What I'm looking for is a .Net OpenGL wrapper that is written in clear OOP principles, easy to use ( easy to apply textual and lighting, easy to debug etc), able to rotate the 3D diagram with mouse ( a feature that is critically missing from OpenGL and TAO), and the ability to export to other file formats ( such as dwg or dxf or Google Map file format). Any suggestion? Both Open source or commercial components would do.

• jQuery slideToggle stay open on hover

  - by durilai

  I have a div that I have bound the jQuery hover event to activate a slideDown using slideToggle: <div class="Square"> <div class="RedSquare"></div> <div class="GraySquare"></div> </div> $("div.RedSquare").hover( function() { $(this).siblings("div.GraySquare").slideToggle("fast"); }, function() { $(this).siblings("div.GraySquare").slideToggle("fast"); } ); It toggles a div '.GraySquare' right below it. Basically making a gray box slide down from the red box. The problem I am facing is that when the mouse moves over the gray div the slide toggles up. I want it to remain down when hovering over the red or gray square. Any help is appreciated.

• Trying to issue a mouseclick event on a QWebElement in QWebView QtWebKit

  - by Bad Man

  I'm trying to send a mouse click event on a certain element in the QtWebKit DOM but I'm obviously doing it wrong: QWebElement el=this->page()->mainFrame()->findFirstElement("input[type=submit]"); el.setFocus(); QMouseEvent pressEvent(QMouseEvent::MouseButtonPress, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this->page()->mainFrame(), &pressEvent); QMouseEvent releaseEvent(QMouseEvent::MouseButtonRelease, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this->page()->mainFrame(), &releaseEvent); Any ideas? (p.s. I am extending QWebView if it wasn't obvious)

• Pair programming tools that are not remote

  - by JonathanTech

  I am currently in a job where we practice serious pair programming on windows machines. We both have a set of keyboards, mice, and we have two monitors, which works well for switching who's the driver really easy, but there are some points in the session that I would like to start writing tests at the same time that my pair is writing implementation. I am wondering if there is any program that would allow me to have effectively two cursors and keyboard focuses on the same computer. If they don't exist then I am willing to experiment with my own solution, but I would like input as to how to best accomplish this. I am most familiar with .Net 3.5 technologies, but I also know Java and am willing to learn C++ to solve this problem. If I was creating the solution myself I would go down the road of being able to grab the input of one hardware device (i.e. a specific mouse that's installed) and prevent Windows from moving the pointer, and instead move my own programs pointer independently.

  - by Anil Namde

  I have a table full of cells and i would like to get on which cell the mouse is. For this i have attached events to all the cells and then i am finding the elements.

Is it possible that i attach only single event handler on top and still be able to catch all the information. like which cell user is currently on etc. Something like below, <table onMouseOver="monitorFuntion(event)" >...</table>

• Difference between focus and focus-in(out)-event signals

  - by spajak

  Hello What's the difference between "focus" and "focus-in(out)-event" signals in GTK+? Which one is emitted firs? How are they related to keyboard(TAB) & mouse clicks. Do they depend on each other? I'm asking this because I want to keep track of currently focused widget within toplevel window and I don't want to test HAS_FOCUS flag of every widget when I need it. The widgets I'm interested of are deep inside other containers, boxes etc. What would be the best way in this situation for keeping & updating focused widget pointer?

• Where to start on creating finger swipe navigation in an collection of items

  - by Thomas Stock

  Lets say I want to make a control to select any integer number by dragging on a "bar" with numbers: (156 is selected) Mousedown on "159" and dragging towards the left and then doing mouseup changes the control to this: (160 is selected) I've been experimenting for the past 3 hours but I'm inexperienced in Silverlight so I'm having problems getting started. My current guess is I should seperate this into 2 steps: Step 1: Build this control without swiping behavior. Just 2 buttons to go up a number or go down a number Step 2: Replace the buttons by handling mouse events. With my limited knowledge I think I would manage building a crappy control that does this, with very messy xaml and c# and lots of headaches when trying to apply styling and fancy state transitions, but I was hoping some xaml wizards could get me started with the basic approach? Edit: This is an implementation of what I'm trying to achieve in Silverlight: Iphone's datepicker:

• WPF Animation on scrollviewer children clipped by scrollviewer

  - by Becky Franklin

  Hey folks, I'm hoping I have a fairly simple problem that can be fixed easily as it seems like I'm just missing something basic from the WPF world. I have a scrollviewer wrapping a stackpanel which contains several images, these images have animations to increasing in size when the mouse passes over them. All works fine without the scrollviewer, now I've added the scrollviewer, the animation works but only inside the scrollviewer; the increasing size isn't being allowed to overlap the scrollviewer. Is there a way to fix this? Thanks, Becky

• WPF, TreeView bug, can't select root item after item removed from treeview

  - by user275587

  I have a very weird bug in a three level deep TreeView. It is intermittent and I can't find how to reproduce it consistently. After programmatically removing, adding then removing some third level items, when I click on the root item it isn't selected. It can still expand/collapse but can't be selected with a mouse click and it doesn't fire ItemSelectionChange event. You can click to select a second level or third level items and after that you're finally able to select the root item. I've tried to set IsSelected = false for all items after removing and tried to do a nice clean-up when removing items but it doesn't help. Did anybody run into that bug? Do you have any suggestions to remove this bug?

• How to edit a link within a contentEditable div

  - by Travis

  Does anyone have any suggestions on how to edit an link in a contentEditable div? It would be ideal once the link is either clicked with mouse, or the cursor hits the link, that the a small prompt would pop up and allow the user to change the href property of the link. The prompt isn't the issue, but how is it possible to detect the link has been either clicked or that the cursor has arrived at the link? onfocus doesn't seem to work in a contentEditable div on Firefox & Safari. Any ideas?

• WinForms Taskbar Icon - Click Event not firing

  - by Greycrow

  I have created a non-form c# program that uses the NotifyIcon class. The text "(Click to Activate)" shows up when I hover the mouse. So I am getting some events handled. However, The "Click" event does not fire and the Context menu doesnt show up. public class CTNotify { static NotifyIcon CTicon = new NotifyIcon(); static ContextMenu contextMenu = new ContextMenu(); static void Main() { //Add a notify Icon CTicon.Icon = new Icon("CTicon.ico"); CTicon.Text = "(Click to Activate)"; CTicon.Visible = true; CTicon.Click += new System.EventHandler(CTicon_Click); //Create a context menu for the notify icon contextMenu.MenuItems.Add("E&xit"); //Attach context menu to icon CTicon.ContextMenu = contextMenu; while (true) //Infinite Loop { Thread.Sleep(300); //wait } } private static void CTicon_Click(object sender, System.EventArgs e) { MessageBox.Show("Clicked!"); } }

• Aaron Hillegass Chapter 18 Challenge Question

  - by jasonbogd

  I am working through Aaron Hillegass' Cocoa Programming for Mac OS X and am doing the challenge for Chapter 18. Basically, the challenge is to write an app that can draw ovals using your mouse, and then additionally, add saving/loading and undo support. I'm trying to think of a good class design for this app that follows MVC. Here's what I had in mind: Have a NSView-subclass that represents an oval (say JBOval) that I can use to easily draw an oval. Have a main view (JBDrawingView) that holds JBOvals and draws them. The thing is that I wasn't sure how to add archiving. Should I archive each JBOval? I think this would work, but archiving an NSView doesn't seem very efficient. Any ideas on a better class design? Thanks.

• How do I make my drop down remain dropped down?

  - by counterbeing

  The site I'm currently working on is located at: http://counterbeing.com The problem I'm trying to solve is that when you run your mouse over the "Categories" button, the sub-menu items pop up, but then disappear before you can click them. I've tried a variety of things. For one thing, I was attempting to define the div that the sub menu items are wrapped in as something that will also trigger the animation, but that doesn't seem to work... Here is the javascript file I'm using to grab both layers. I have it divided into 2 layers because one of them is somewhat transparent. $(document).ready(function() { ($("div#CategoriesLink").hover(function(){ $("div#navdrop").animate({ top: "0px" }) $("div#CategoryButtonHolder").animate({ top: "0px" }) }); });

• Silverlight TabItem template not working correctly

  - by Savvas Sopiadis

  Hello everybody! In a SL4 application i need to restyle my TabItems (actually add a button in the header). So i took the TabItem's control template from here and added the functionality i wanted. This seems to work fine, (i could dynamically add tabitems) with one exception: i think this posted control template is behaving somehow "arbitrary": every time the mouse hoovers over a non selected TabItem header, this gets selected WHITHOUT clicking!! (afaik this is not the default behavior: the user user has to click a header to make this tabitem the selected one). I tried to find why it is behaving like this, with no luck! Is there someone who can enlighten my darkness??? Thanks in advance!

• Move multiple BufferedImage in Java2D?

  - by zo0mbie

  How can I mousedrag different BufferedImages in Java2D? For instance, if I have ten or more images, how can I move that images which my mouse is over? Now I'm importing an BufferedImage with BufferedImage img = new BufferdImage(new File("filename")); And I'm painting this with Graphics2D with public void paintComponent(Graphics g) { super.paintComponent(g); g2d = (Graphics2D) g; g2d.drawImage(img, x1, y1, null); g2d.drawImage(img2, x2, y2,null); } Everytime I'm moving on a image I'm repaint()-ing the entire screen. My mousemove class is as follows class MouseMotionHandler extends MouseMotionAdapter { @Override public void mouseDragged(MouseEvent e) { x1 = e.getX() - (img.getWidth() / 2); y1 = e.getY() - (img.getHeight() / 2); repaint(); } } With this method I'm able to "drag" one picture, but what to do when I will drag more individually?

• What's the Best Practice for Firing Manual OnClick Events?

  - by Tyler Murry

  Hey guys, I've got an XNA project that will be drawing several objects on the screen. I would like the user to be able to interact with those items. So I'm trying to build a method that checks to see which object the mouse is over, out of those which is the top most, and then fire an OnClick event for that object. Checking for the things above is not the problem, but where to actually put that logic is most of the issue. My initial feeling is that the checking should be handled by a master object - since it doesn't make sense for an object, who ideally knows only about itself, to determine information about the other objects. However, calling OnClick events remotely from the master object seems to be counter-intuitive as well. What's the best practice in this situation? Thanks, Tyler

• Serial Mac OS X constantly freezes/locks/dissappears for USB to Arduino

  - by Niraj D

  I have a problem with my C++ code running in Xcode with both the AMSerial library as well as the generic C (ioctl, termios). After a fresh restart, my application works well but after I "kill" the program the Serial (I think) is not released. I have checked my open files under /dev and have killed the connection to serial USB from there, but my C++ still can't open the USB port. I have narrowed this down to being a low level Mac OS X issue, regarding blocking the port indefinitely, regardless of closing it using the aforementioned libraries. Just for context, I'm trying to send numbers through my USB port, serially to an Arduino Duemilanove at 9600 baud. Running Serial Monitor in Arduino is perfectly fine, however, running through a C++ application it freezes up my computer, occasionally, my mouse/keyboard freeze up: requiring a hard reset. How can this problem be fixed? It seems like Mac OS X is not USB friendly!

• FF extension: a popup with dynamic menuitems, with each menu item having another popup

  - by encryptor

  I am building an extension that has a popup whose elements are constructed by a function call everytime the mouse hovers over the popup option. I am able to achieve this. Now I need to have a popup for each of the menu item (inside the original popup) which is not dynamic though. I have this code, but it does not work: var myMenuPopup = document.getElementById("file-popup4"); for (var m=0; m var newItem = document.createElement("menupopup"); newItem.setAttribute("label", publicdisplayname[m]); newItem.setAttribute("id", "public" + m); var new1 = document.createElement("menuitem"); new1.setAttribute("label","Home"); new1.setAttribute("id", "publichome" + m); newItem.onclick = function(){ } newItem.appendChild(new1); myMenuPopup.appendChild(newItem); but this doesnt work. Can someone please help me out with whats the problem

• Can a struct become deallocated?

  - by brettr

  I've declared a struct in my header file like this: typedef struct { NSString *department; NSString *departmentId; } Department; Department currentDepartment; This struct is in a fairly simple class. I assign the struct values in viewDidLoad. Just before leaving viewDidLoad, I see the struct values are still there. After the user clicks a segment control, I reassign the struct values. Before assigning values, I see the two struct values are 0x0. I do have NSZombieEnabled, which is printing out this when I mouse over the struct while the app is running and one of my breakpoints have been hit: MyApp[25722:207] *** -[CFString _cfTypeID]: message sent to deallocated instance 0xfc0e90 I'm not creating an instance of the struct or deallocating it. How can it be getting deallocated?

• Silverlight tests not working unless RDP connection open

  - by Duncan Bayne

  I have a few Silverlight UI tests that I'm automating with White. These tests are subsequently run by a TFS build agent, which is running interactively so it can access the desktop. The build passes if I have a Remote Desktop connection open to the build agent as the tests are run; I can see the mouse pointer moving around. When the test clicks on a HyperlinkButton navigation takes place, and is subsequently verified by assertions within the test. The build fails if I do not have a Remote Desktop connection open to the build agent as the tests are run. The Internet Explorer window is created and the Silverlight app loads, but no clicks happen; the application remains on the initial page and test assertions subsequently fail. Has anyone out there found a solution to this problem?

• How do I control when a contextMenuStrip is displayed?

  - by GregH

  In vb.net (2008), I want to be able to control when a contextMenuStrip (context menu) is displayed. I don't want it to always appear when the right mouse button is clicked...only when certain criteria within my program are met. I figure I would use addHandler but I'm not exactly clear on how to completely control the opening of the contextMenuStrip. I know I would issue a call to the "open" method to render the contextMenuStrip. However, I am unclear as to how to completely take over control of when to render the contextMenuStrip.
