• Cleaning up when exiting an OpenGL app

  - by Daniel

  This might be a dumb question but I've spent some time asking Google and haven't been able to find anything. I have an an OSX OpenGL app I'm trying to modify. When I create the app a whole bunch of initialisation functions are called -- including methods where I can specify my own mouse and keyboard handlers etc. For example: glutInit(&argc, argv); glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA); glutInitWindowPosition(100, 100); glutInitWindowSize(700, 700); glutCreateWindow("Map Abstraction"); glutReshapeFunc(resizeWindow); glutDisplayFunc(renderScene); glutIdleFunc(renderScene); glutMouseFunc(mousePressedButton); glutMotionFunc(mouseMovedButton); glutKeyboardFunc(keyPressed); At some point I pass control to glutMainLoop and my application runs. In the process of running I create a whole bunch of objects. I'd like to clean these up. Is there any way I can tell GLUT to call a cleanup method before it quits?

• MouseListener fired without checking JCheckBox

  - by Morinar

  This one is pretty crazy: I've got an AppSight recording (for those not familiar, it's a recording of what they did including keyboard/mouse input + network traffic, etc) of a customer reproducing a bug. Basically, we've got a series of items listed on the screen with JCheckBox-es down the left side. We've got a MouseListener set for the JPanel that looks something like this: private MouseAdapter createMouseListener() { return new MouseAdapter(){ public void mousePressed( MouseEvent e ) { if( e.getComponent() instanceof JCheckBox ) { // Do stuff } } }; } Based on the recording, it appears very strongly that they click just above one of the checkboxes. After that, it's my belief that this listener fired and the "Do stuff" block happened. However, it did NOT check the box. The user then saw that the box was unchecked, so they clicked on it. This caused the "Do stuff" block to fire again, thus undoing what it had done the first time. This time, the box was checked. Therefore, the user thinks that the box is checked, and it looks like it is, but our client thinks that the box is unchecked as it was clicked twice. Is this possible at all? For the life of me, I can't reproduce it or see how it could be possible, but based on the recording and the data the client sent to the server, I can't see any other logical explanation. Any help, thoughts, and or ideas would be much appreciated.

• Error 2025: The supplied DisplayObject must be a child of the caller

  - by Mocca

  Hi, sorry, new to actionscript 3. I have a display() function for an object rotator(image based like a QT object movie). It first saves the current image in a helper variable and then allocates a new image, from the library, beneath the old one. To get a nice crossfade effect, the old image's alpha is looped down via enter_frame and then removed. Which is where there seems to be an issue with the display list, maybe recognizing oldImg's value as being already added? (it's not a first pass error) Btw, do i have to remove the old image or can i leave it, for when it's being called up via the mouse position again? (the image number can get fairly large) Does anyone have further insight? Thanks! function display(num:Number):void //num: image number { ... oldImg = newImg; ClassReference = getDefinitionByName("Class"+num) as Class; imgBD = new ClassReference(0,0); newImg = new Bitmap(imgBD); images.addChild(newImg); newImg.x=0; newImg.y=0; } function onEnter(evt:Event):void { if (oldImg) { if (oldImg.alpha > 0) oldImg.alpha -= 0.15; **else images.removeChild(oldImg);** } ... }

• Use a foreign key mapping to get data from the other table using Python and SQLAlchemy.

  - by Az

  Hmm, the title was harder to formulate than I thought. Basically, I've got these simple classes mapped to tables, using SQLAlchemy. I know they're missing a few items but those aren't essential for highlighting the problem. class Customer(object): def __init__(self, uid, name, email): self.uid = uid self.name = name self.email = email def __repr__(self): return str(self) def __str__(self): return "Cust: %s, Name: %s (Email: %s)" %(self.uid, self.name, self.email) The above is basically a simple customer with an id, name and an email address. class Order(object): def __init__(self, item_id, item_name, customer): self.item_id = item_id self.item_name = item_name self.customer = None def __repr__(self): return str(self) def __str__(self): return "Item ID %s: %s, has been ordered by customer no. %s" %(self.item_id, self.item_name, self.customer) This is the Orders class that just holds the order information: an id, a name and a reference to a customer. It's initialised to None to indicate that this item doesn't have a customer yet. The code's job will assign the item a customer. The following code maps these classes to respective database tables. # SQLAlchemy database transmutation engine = create_engine('sqlite:///:memory:', echo=False) metadata = MetaData() customers_table = Table('customers', metadata, Column('uid', Integer, primary_key=True), Column('name', String), Column('email', String) ) orders_table = Table('orders', metadata, Column('item_id', Integer, primary_key=True), Column('item_name', String), Column('customer', Integer, ForeignKey('customers.uid')) ) metadata.create_all(engine) mapper(Customer, customers_table) mapper(Orders, orders_table) Now if I do something like: for order in session.query(Order): print order I can get a list of orders in this form: Item ID 1001: MX4000 Laser Mouse, has been ordered by customer no. 12 What I want to do is find out customer 12's name and email address (which is why I used the ForeignKey into the Customer table). How would I go about it?

• Cannont Update control in WPF custom control

  - by Fazi

  I have created a custom control which holds a button in it. The button is styled, so as to hold a grid with two rows, an image in the first and a TextBlock in the second. I have written an Event Handler for the custom control. When the mouse enters the path of the object the MouseEnter event fires, where I try to change the TextBlock's FontSize and Foreground color, however the control does not update. In contrast, I have tried to modify an regular TextBlock's(not part a custom control and controltemplate) properties, and they update correctly, on the fly. What am I missing here?? Here is the code for the event handler: private void ThemeButton_MouseEnter(object sender, MouseEventArgs e) { InitializeProperties(); TextElement.FontSize = 16; TextElement.Text = "new text"; TextElement.Foreground = Brushes.Red; TextBlock element = MainWindow.FindChild<TextBlock>(MainWindow.StartWindow, "textField"); element.Text = "new text for regular textblock"; element.Foreground = Brushes.Red; } InitializeProperties is a methid that initializes TextElement(typeof TextBlock) and ImageElement(typeof Image) properties. They are not null. The properties are just regular .NET properties.

• How can I make VS2010 insert using statements in the order dictated by StyleCop rules.

  - by Hamish Grubijan

  The related default StyleCop rules are: Place using statements inside namespace. Sort using statements alphabetically. But ... System using come first (still trying to figure out if that means just using System; or using System[.*];). So, my use case: I find a bug and decide that I need to at least add an intelligible Assert to make debugging less painful for the next guy. So I start typing Debug.Assert( and intellisense marks it in Red. I hover mouse over Debug and between using System.Diagnostics; and System.Diagnostics.Debug I choose the former. This inserts using System.Diagnostics; after all other using statements. It would be nice if VS2010 did not assist me in writing code that won't build due to warnings as errors. How can I make VS2010 smarter? Is there some sort of setting, or does this require a full-fledged add-in of some sort?

• Eclipse cannot find existing project in build path

  - by PNS

  Here is probably one of the idiosyncrasies of Eclipse and its handling of build paths, which cannot be fixed despite all sorts of workarounds tested so far. The issue relates to a workspace of several projects, each of which compiles into its own JAR. Dependencies among the projects are resolved by adding the relevant ones to the build path (no Maven or other external tool or plugin is used), via Project -> Properties -> Java Build Path -> Projects Among all these projects, a couple (say, com.example.p1 and com.example.p2) refuse to recognize a third (and simple) one (say, com.example.p3), while all other projects do. So, although P3 is added to the build path, all related classes from P3 are imported properly and the source code of each such class is accessible by hitting F3, Eclipse keeps complaining that The import com.example.p3 cannot be resolved and SomeClass cannot be resolved to a type where com.example.p3.SomeClass is one of the P3 classes. If instead of the P3 project I put its compiled JAR in the build path, the issue disappears. However, code in P3 changes frequently and it is a time waste to keep compiling and refreshing the workspace so that the change is picked up, not to mention that this should not happen in an IDE anyway (and it does not for the other projects using P3). Among the workarounds tried are things like: Removing and adding again P1, P2, P3 Cleaning up and recompiling everything Checking whether any other project loads the P3 JAR Putting P3 at the top of the Eclipse build path "Order and Export" list Using the "Fix project setup" suggestion of Eclipse (available when hovering the mouse over the red-underlined-error compilation line). Actually, this option offers adding to the build path either P3 or its JAR, but if P3 is added, the issue reappears. Any ideas?

• Firefox handles xxx.submit(), Safari doesn't ... what can be done?

  - by Prairiedogg

  I'm trying to make a pull down menu post a form when the user selects (releases the mouse) on one of the options from the menu. This code works fine in FF but Safari, for some reason, doesn't submit the form. I re-wrote the code using jquery to see if jquery's .submit() implementation handled the browser quirks better. Same result, works in FF doesn't work in safari. The following snippets are from the same page, which has some django template language mixed in. Here's the vanilla js attempt: function formSubmit(lang) { if (lang != '{{ LANGUAGE_CODE }}') { document.getElementById("setlang_form").submit(); } } Here's the jquery attempt: $(document).ready(function() { $('#lang_submit').hide() $('#setlang_form option').mouseup(function () { if ($(this).attr('value') != '{{ LANGUAGE_CODE }}') { $('#setlang_form').submit() } }); }); and here's the form: <form id="setlang_form" method="post" action="{% url django.views.i18n.set_language %}"> <fieldset> <select name="language"> {% for lang in interface_languages %} <option value="{{ lang.code }}" onmouseup="formSubmit('{{ lang.name }}')" {% ifequal lang.code LANGUAGE_CODE %}selected="selected"{% endifequal %}>{{ lang.name }}</option> {% endfor %} </select> </fieldset> </form> My question is, how can I get this working in Safari?

• HTML email image inverts on link click Outlook 07/10/13

  - by Matt Maclennan

  I'm having an issue on a HTML email in Word rendered Outlooks (2007, 2010, 2013) where I click an image link, and when the mouse is clicked, the image inverts... Here is the code below... <td align="left" width="360" valign="top" style="mso-table-lspace: 0pt; mso-table-rspace: 0pt; border-collapse: collapse;" class="hide"> <a href="#" target="_blank"> <img src="test.jpg" width="360" height="528" alt="alt tag" style="display:block;" class="img_mob centertable" border="0" align="left"> </a> </td> Here is a comparison on the image clicked/not clicked... I have tried putting a text-decoration: none on the link. All the links are styled inline as well. This is the only image that it is having this issue on the email, so tried re-saving the image with no luck. The image is saved as a JPEG and SRGB from a Photoshop PSD. Any ideas? Thanks.

• Division of text follow the cursor via Javascript/Jquery

  - by webzide

  Dear experts, I wanted have a dynamic division of content follow you with the cursor in the web browser space. I am not a pro at JS so I spent 2 hours to finally debugged a very stupid way to accomplish this. $(document).ready(function () { function func(evt) { var evt = (evt) ? evt : event; var div = document.createElement('div'); div.style.position = "absolute"; div.style.left = evt.clientX + "px"; div.style.top = evt.clientY + "px"; $(div).attr("id", "current") div.innerHTML = "CURSOR FOLLOW TEXT"; $(this).append($(div)); $(this).unbind() $(this).bind('mousemove', function () { $('div').remove("#current"); }); $(this).bind('mousemove', func); } $("body").bind('mousemove', func) }); As you can see this is pretty much Brute force and it slows down the browser quite a bit. I often experience a lag on the browser as a drag my mouse from one place to another. Is there a way to accomplish this easier and faster and more intuitive. I know you can use the cursor image technique but thats something I'm looking to avoid. Thanks in advance.

• jqtouch - panels appear on page, class="back" not working in Safari

  - by user564816

  I'm trying to get a demo working that was used in J. Stark's webinar on Safari Books Online (still available for viewing). I think I've followed the code example correctly, but the class="back" objects used to return from the "blog", "contacts", "settings" and "about" panels do not work, though the correct address shows in the nav area at the base of the browser window when I hover the mouse over the respective link. The panels-- which should slide in and out when called by their respective class"arrow" elements-- appear on the main page, nor do they animate correctly. Browser is Safari 5.0.3(6533.19.4); jquery-1.3.2; jqtouch freshly downloaded from the jqt website. Obviously I'm missing something simple. I'd sincerely appreciate anyone's help who sees what I'm doing wrong. Thanks for considering my question. View the app and source code (use view source in your browser) here. Sat 8 January 2011: 1 48 AM UPDATE in response to JS's comments: Most humble thanks for your note. Didn't want to impose on your server, so the URL for jqtouch.min.css points to a version on my server @ fastermac.net. There's something further amiss, I believe. On load, page still shows the elements that should be invisible until called by clicking class="arrow" elements. Animations not yet wiggling. Did get them to wiggle at one point, but "flip," for instance, landed then on a black page-- not the targeted panel. Probably something obvious, but I'm missing it after some considerable due diligence. Again, thanks for your note. Any further illumination would be sincerely appreciated.

• svg mouseup event not fired in IE9, unless the debugger is open

  - by Roberto Lupi

  I am using d3 to build a simple chart that the user can edit interactively with the mouse. It works on in all modern common browser (Chrome, Firefox, Safari), except for Internet Explorer 9 where I can start to drag an item but I never get the mouseup event. The strangest bit is that, if I open the debugger, the page works percetly on Internet Explorer 9 as well. My code looks like this: item.append("svg:circle") .attr("class", "handle") .attr("opacity",0.5) .attr("stroke","gray") .attr("cx", bx(0.5)-bx(0)) .attr("r", 10) .style("cursor", "crosshair") .style("pointer-events", "all") .call(d3.behavior.drag() .on("dragstart", function() { dragTarget = d3.select(this); }) .on("drag", function() { this.parentNode.appendChild(this); // put us on the front, not really needed var dragTarget = d3.select(this); dragTarget .attr("cy", function() { return d3.event.dy + parseInt(dragTarget.attr("cy"))}); }) .on("dragend", function(d, i) { newY = parseInt(d3.select(this).attr("cy")); newValue = y.invert(newY); var serieNo = this.__data__.serieNo; console.log([serieNo+1,i+1]); data[serieNo+1][i+1] = newValue; updateBarChart(); onchange(); }) );

• Need of optimized code for hide and show div in jQuery

  - by novellino

  Hello, I have a div: <div id="p1" class="img-projects" style="margin-left:0;"> <a href="project1.php"> <img src="image1.png"/></a> <div id="p1" class="project-title">Bar Crawler</div> </div> On mouse-over I want to add an image with opacity and make the project-title shown. So I use this code: <script type="text/javascript"> $(function() { $('.project-title').hide(); $('#p1.img-projects img').mouseover( function() { $(this).stop().animate({ opacity: 0.3 }, 800); $('#p1.project-title').fadeIn(500); }); $('#p1.img-projects img').mouseout( function() { $(this).stop().animate({ opacity: 1.0 }, 800); $('#p1.project-title').fadeOut(); }); $('#p2.img-projects img').mouseover( function() { $(this).stop().animate({ opacity: 0.3 }, 800); $('#p2.project-title').fadeIn(500); }); $('#p2.img-projects img').mouseout( function() { $(this).stop().animate({ opacity: 1.0 }, 800); $('#p2.project-title').fadeOut(); }); }); </script> The code works fine but does anyone know a way to optimize my code? Thank you

• Can the Visual Studio (2010) Command Window handle "external tools" with project/solution relative p

  - by ee

  I have been playing with the Command Window in Visual Studio (View-Other Windows-Command Window). It is great for several mouse-free scenarios. (The autocompleting file "Open" command rocks in a non-trivial solution.) That success got me thinking and experimenting: Possibility 1.1: You can use the Alias commands to create custom commands Possibility 1.2: You can use the Shell command to run arbitrary executables and specify parameters (and pipe the result to the output or command windows) Possibility 2: A previously setup external tool definition (with project-relative path variables) could be run from the command window What I am stuck on is: There doesn't appear to be a way to send parameters to an aliased command (and thus the underlying Shell call) There doesn't appear to be a way to use project/solution relative paths ($SolutionDir/$ProjectDir) on a Shell call Using absolute paths in Shell works, but is fragile and high-maintenance (one alias for each needed use case). Typically you want the command to run against a file relative to your project/solution. It seems you can't run the traditional external tools (Tools-External Tools...) in the command window Ultimately I want the external tool functionality in the command window in some way. Can anyone see a way to do this? Or am I barking up the wrong tree? So my questions: Can an "external tool" of some sort (using relative project/solution path parameters) be used in the Command Window? If yes, How? If no, what might be a suitable alternative?

• Active State Image Display

  - by fmz

  I have some images that need to change, based not only on hover, but also on active state. If you look at the page here: http://site427.mysite4now.net/tazthedog/site1/ There are some tabs with Screen Printing Quick Links, etc. The tab image is associated with the link and displays properly. The icon in tabs defaults to the gray and turns blue on mouse over, however, I also need it to be blue on the "active" state. Here is the css: .quick-links em:hover { background: transparent url(../images/quick-links.png) 10px 9px no-repeat ; display: block ; float: left; } Here is the html: <ul class="tabs"> <li class="quick-links"> <a href="#quickLinks" id=""> <em> <span>Screen Printing Quick Links</span> </em> </a> </li> <li class="distributor-ql"> <a href="#distributorQL" id=""> <em> <span>Dealer &amp; Distributor Quick Links</span> </em> </a> </li> </ul> I tried adding a .quick-links em:active... but that doesn't maintain it. I know there is a way to keep the icon blue while in the active state, I just need a little help to understand what that is. Thanks!

• Which way to go in Linux 3D programming?

  - by Tek

  I'm looking for some answers for a project I'm thinking of. I've searched and from what I understand (correct me if I'm wrong) the only way the program I want to make will work is through 3D application. Let me explain. I plan to make a studio production program but it's unique in the fact that I want to be able to make it fluid. Let me explain. Imagine Microsoft's Surface program where you're able to touch and drag pictures across the screen. Instead of pictures I want them to be sound samples (wavs,mp3,etc). Of course instead the input will be with the mouse but if I ever do finish the project I would totally add touch screen input compatibility! Anyway, I'm guessing there's "physics" to do with it which is why I'm thinking that even though it'll be a 2D application I'll need to code it in a 3D environment. Assuming that I'm correct in how I want to approach my project, where can I start learning about 3D programming? I actually come from PHP programming which will make C++ easier for me to learn. But I don't even know where to start. If I'm not wrong OpenGL is the most up to date API as far as I know. Anyway, please give me your insights guys. I could really use some guidance here since I could totally be wrong in everything that I wrote :)

• Flex/Flash: Don't show 'bar' cursor when dragging over a TextField/TextArea?

  - by David Wolever

  As the title suggests, how can I prevent the "bar" cursor from appearing when I click-and-drag over a TextField? For example, consider this interaction: I'd like to prevent the cursor changing to the "bar" in step "2". How can I do that? I've tried fiddling with the selectable flag: protected static function fixMouseOverAfordance(field:TextField):void { var iOwnClick:Boolean = false; function handleMouseOver(event:MouseEvent):void { if (event.buttonDown) { field.selectable = iOwnClick; } else { field.selectable = true; iOwnClick = false; } } field.addEventListener(MouseEvent.MOUSE_OVER, handleMouseOver, false, EventPriority.CURSOR_MANAGEMENT+1); field.addEventListener(MouseEvent.ROLL_OVER, handleMouseOver, false, EventPriority.CURSOR_MANAGEMENT+1); field.addEventListener(MouseEvent.MOUSE_MOVE, handleMouseOver, false, EventPriority.CURSOR_MANAGEMENT+1); field.addEventListener(MouseEvent.MOUSE_DOWN, function(event:MouseEvent):void { iOwnClick = true; field.selectable = true; }); } But the "bar" cursor still appears the first time the mouse is moved over the text field (however, after it has been moved out then moved back in, it does the right thing).

• IE7 - jquery addClass() breaks floating elements

  - by Patrick

  I have this nav that uses addClass('hover') when the mouse is rolled over an item. This works fine except in IE7 when the addClass function is called every element with float:left stops floating and the page totally loses its structure. This is my JS: _this.position_sub_menus = function(){ $('#header #nav > ul > li').mouseenter( function(e){ pos = $(this).offset(); height = $(this).height(); lvl2 = '#' + $(this).attr('id') + '-submenu'; if( $(this).position().left > ($('#nav').width()/2)){ pos.left = pos.left - $(lvl2).width() + $(this).width(); } $(this).addClass('hover'); $(lvl2).show(); $(lvl2).css( { 'left' : (pos.left - 12) + 'px', 'top' : pos.top + height + 'px'}); } ); This is the CSS of the of the elements that break: display: inline; float: left; margin-left: 10px; margin-right: 10px; position: relative; It's CSS from the 960 grid system. When I comment out the $(this).addClass('hover'); line the floated elements dont break. Is anyone familiar with this IE7 problem? Thanks guys

• Dom Traversal to Automate Keyboard Focus - Spatial Navigation

  - by Steve

  I'm going to start with a little background that will hopefully help my question make more sense. I am developing an application for a television. The concept is simple and basically works by overlaying a browser over the video plane of the TV. Now being a TV, there is no mouse or additional pointing device. All interaction is done through a remote control. Therefore, the user needs to be able to visually tell which element they are currently focused upon. To indicate that an element is focused, I currently append a colored transparent image over the element to indicate focus. Now, when a user hits the arrow keys, I need to respond by focusing on the correct elements according to the key pressed. So, if the down arrow is pressed I need to focus on the next focusable element in the DOM tree (which may be a child or sibling), and if they hit the up arrow, I need to respond to the previous element. This would essentially simulate spatial navigation within a browser. I am currently setting an attribute (focusable=true) on any DOM elements that should be able to receive focus. What I would like to do is determine the previous or next focusable element (i.e. attribute focusable=true) and apply focus to the element. I was hoping to traverse the DOM tree to determine the next and previously focusable elements, but I am not sure how to perform this in JQuery, or in general. I was leaning towards trying to use the JQuery tree travesal methods like next(), prev(), etc. What approach would you take to solve this type of issue? Thanks

• Click at specified client area

  - by VixinG

  Click doesn't work - I don't know why and can't find a solution :( ie. Click(150,215) should move mouse to the client area and click there.

[DllImport("user32.dll")] static extern void mouse_event(int dwFlags, int dx, int dy, int dwData, int dwExtraInfo); const int LEFTDOWN = 0x00000002; const int LEFTUP = 0x00000004; static void Click(int x, int y) { MouseMove(x, y); mouse_event((int)(LEFTDOWN), 0, 0, 0, 0); mouse_event((int)(LEFTUP), 0, 0, 0, 0); }

• How to map keys in vim differently for different kinds of buffers

  - by Yogesh Arora

  The problem i am facing is that i have mapped some keys and mouse events for seraching in vim while editing a file. But those mappings impact the functionality if the quickfix buffer. I was wondering if it is possible to map keys depending on the buffer in which they are used. EDIT - I am adding more info for this question Let us consider a scenario. I want to map <C-F4> to close a buffer/window. Now this behavior could depend on a number of things. If i am editing a buffer it should just close that buffer without changing the layout of the windows. I am using buffkil plugin for this. It does not depend on extension of file but on the type of buffer. I saw in vim documentation that there are unlisted and listed buffer. So if it is listed buffer it should close using bufkill commands. If it is not a listed buffer it should use <c-w>c command to close buffer and changing the window layout. I am new at writing vim functions/scripts, can someone help me getting started on this
