  • Background problem of opengl 3d object over iphone camera view

    - by user292127
    Hi, I'm loading opengl 3d objects over the iphone camera view. When opengl view is loaded it's loading with a opengl 3d object with black background. The black background color will block the camera view.I just want to clear background color of opengl view so that I could load only the 3d object to the camera view. I had tried glclearcolor(1.0,1.0,1.0,0.0); but no change to background color. I had also tried to clear background color opengl view using [glview setbackgroundColor:[UIColor clearColor]];. No change in back ground color. Can any one help me with this stuff ? I'm new to opengl. Thanks in advance

  • wxPython: Sending a signal to several widgets

    - by cool-RR
    I am not even sure how to ask this question. I want something that is like the wxPython event system, but a bit different. I'll try to explain. When there is a certain change in my program (a "tree change", never mind what that is,) I want to send a signal to all the widgets in my program, notifying them that a "tree change" has occurred, and they should change their display in response. How do I do this? It sounds a little bit like wxPython events, but not really, since events don't spread to all widgets, as far as I know. What would be a good way to do this?

  • Android Drawable question.

    - by Tarmon
    Hey Everyone, I am trying to create a drawable in code and change the color based on some criteria. I can get it to work but it doesn't want to let me set the padding on the view. Any help would be appreciated. <?xml version="1.0" encoding="utf-8"?> <ImageView android:id="@+id/icon" android:layout_width="50px" android:layout_height="fill_parent" /> <TextView android:id="@+id/label" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingLeft="17px" android:textSize="28sp" /> ImageView icon = (ImageView) row.findViewById(R.id.icon); ShapeDrawable mDrawable; int x = 0; int y = 0; int width = 50; int height = 50; float[] outerR = new float[] { 12, 12, 12, 12, 12, 12, 12, 12 }; mDrawable = new ShapeDrawable(new RoundRectShape(outerR, null, null)); mDrawable.setBounds(x, y+height, x + width, y); switch(position){ case 0: mDrawable.getPaint().setColor(0xffff0000); //Red break; case 1: mDrawable.getPaint().setColor(0xffff0000); //Red break; case 2: mDrawable.getPaint().setColor(0xff00c000); //Green break; case 3: mDrawable.getPaint().setColor(0xff00c000); //Green break; case 4: mDrawable.getPaint().setColor(0xff0000ff); //Blue break; case 5: mDrawable.getPaint().setColor(0xff0000ff); //Blue break; case 6: mDrawable.getPaint().setColor(0xff696969); //Gray break; case 7: mDrawable.getPaint().setColor(0xff696969); //Gray break; case 8: mDrawable.getPaint().setColor(0xffffff00); //Yellow break; case 9: mDrawable.getPaint().setColor(0xff8b4513); //Brown break; case 10: mDrawable.getPaint().setColor(0xff8b4513); //Brown break; case 11: mDrawable.getPaint().setColor(0xff8b4513); //Brown break; case 12: mDrawable.getPaint().setColor(0xffa020f0); //Purple break; case 13: mDrawable.getPaint().setColor(0xffff0000); //Red break; case 14: mDrawable.getPaint().setColor(0xffffd700); //Gold break; case 15: mDrawable.getPaint().setColor(0xffff6600); //Orange break; } icon.setBackgroundDrawable(mDrawable); icon.setPadding(5, 5, 5, 5); If I set the padding in XML it just ignores it. Thanks, Rob

  • Can Flash AS3 listbox data contain variable info?

    - by Anne
    I'm populating a listbox like this: dp.addItem( {label:"red dress", data:"OV4MP/23OL.swf"} ); Instead of data:"OV4MP/23OL.swf", I would like to make part of the data file name a variable from a dynamic textbox named centerPt that belongs to the parent movieclip, so I did this: dp.addItem( {label:"red dress", data:"OV4MP/23"+MovieClip(parent.parent).centerPt.text+".swf"} ); When I trace the selectedItem.data using: trace("you have selected: "+ overlays.selectedItem.data); trace(MovieClip(parent.parent).centerPt.text); I'm getting: you have selected: OV4MP/23.swf. What I should get is OV4MP/23OL.swf. It is not picking up what is in the dynamic centerPt.text field which are the letters OL eventhough that text field is tracing correctly. Is it possible that data can not hold a variable? Thank you in advance for any help. Anne

  • Help with a pseudo-class, first-child

    - by zac
    I am working on a CMS platform with limited access to the template files and want to try and control some of the layout with pseudo class but no luck yet. Can anyone see what is wrong with this structure and why my pseudo class is being ignored? <div id="main"> <div class="someRandomDiv"></div> <div class="block"> stuff </div> <div class="block"> more stuff </div> </div> and i am trying something like this #main .block {border: 1px solid blue} #main .block:first-child {border: 1px solid red} so with this example I would think the stuff block would have a red border and more stuff would have a blue but it is all just blue. Thanks for any help with this.

  • Exception declared on ANTLR grammar rule ignored

    - by Kaleb Pederson
    I have a tree parser that's doing semantic analysis on the AST generated by my parser. It has a rule declared as follows: transitionDefinition throws WorkflowStateNotFoundException: /* ... */ This compiles just fine and matches the rule syntax at the ANTLR Wiki but my exception is never declared so the Java compiler complains about undeclared exceptions. ./tool/src/main/antlr3/org/antlr/grammar/v3/ANTLRv3.g shows that it's building a tree (but I'm not actually positive if it's the v2 or v3 grammar that ANTLR 3.2 is using): throwsSpec : 'throws' id ( ',' id )* -> ^('throws' id+) ; I know I can make it a runtime exception, but I'd like to use my exception hierarchy. Am I doing something wrong or should that syntax work?

  • How well do zippers perform in practice, and when should they be used?

    - by Rob
    I think that the zipper is a beautiful idea; it elegantly provides a way to walk a list or tree and make what appear to be local updates in a functional way. Asymptotically, the costs appear to be reasonable. But traversing the data structure requires memory allocation at each iteration, where a normal list or tree traversal is just pointer chasing. This seems expensive (please correct me if I am wrong). Are the costs prohibitive? And what under what circumstances would it be reasonable to use a zipper?

  • XML: When to use attributes instead of child nodes?

    - by Rosarch
    For tree leaves in XML, when is it better to use attributes, and when is it better to use descendant nodes? For example, in the following XML document: <?xml version="1.0" encoding="utf-8" ?> <savedGame> <links> <link rootTagName="zombies" packageName="zombie" /> <link rootTagName="ghosts" packageName="ghost" /> <link rootTagName="players" packageName="player" /> <link rootTagName="trees" packageName="tree" /> </links> <locations> <zombies> <zombie> <positionX>41</positionX> <positionY>100</positionY> </zombie> <zombie> <positionX>55</positionX> <positionY>56</positionY> </zombie> </zombies> <ghosts> <ghost> <positionX>11</positionX> <positionY>90</positionY> </ghost> </ghosts> </locations> </savedGame> The <link> tag has attributes, but it could also be written as: <link> <rootTagName>trees</rootTagName> <packageName>tree</packageName> </link> Similarly, the location tags could be written as: <zombie positionX="55" positionY="56" /> instead of: <zombie> <positionX>55</positionX> <positionY>56</positionY> </zombie> What reasons are there to prefer one over the other? Is it just a stylistic issue? Any performance considerations?

  • Continuous builds and Agile vs commit often

    - by Mark Underwood
    Hi All, I'm just doing some formal training in Agile at the moment and one question I have is about the value of Continuous Builds vs value of committing to the version control system often. My understanding with version control is that its better to commit often, because then you have history and the ability to go back to previous changes in a fine grained way. My understanding with Agile and continuous build is that its there to put pressure on the developers to always have working code. That to break the source tree is a taboo thing to do. Now i agree with both of these sentiments, but it occurs to be that sometimes these might be working against each other. You maybe in the middle of a largish code change and want to commit code to make sure you have history, but this will break the source tree. Anybody got any thoughts on this? Cheers Mark.

  • Doing a "Diff" on an Associative Array in javascript / jQuery?

    - by Matrym
    If I have two associative arrays, what would be the most efficient way of doing a diff against their values? For example, given: array1 = { foreground: 'red', shape: 'circle', background: 'yellow' }; array2 = { foreground: 'red', shape: 'square', angle: '90', background: 'yellow' }; How would I check one against the other, such that the items missing or additional are the resulting array. In this case, if I wanted to compare array1 within array2, it would return: array3 = {shape: 'circle'} Whilst if I compared array2 within array1, it would return: array3 = {shape: 'square', angle: '90'} Thanks in advance for your help!

  • Tarballing without git metadata

    - by zaf
    My source tree contains several directories which are using git source control and I need to tarball the whole tree excluding any references to the git metadata or custom log files. I thought I'd have a go using a combo of find/egrep/xargs/tar but somehow the tar file contains the .git directories and the *.log files. This is what I have: find -type f . | egrep -v '\.git|\.log' | xargs tar rvf ~/app.tar Can someone explain my misunderstanding here? Why is tar processing the files that find and egrep are filtering? I'm open to other techniques as well.

  • problem with jquery : minipulating val() property of element

    - by P4ul
    Hi, Please help! I have some form elements in a div on a page: <div id="box"> <div id="template"> <div> <label for="username">Username</label> <input type="text" class="username" name="username[]" value="" / > <label for="hostname">hostname</label> <input type="text" name="hostname[]" value=""> </div> </div> </div> using jquery I would like to take a copy of #template, manipulate the values of the inputs and insert it after #template so the result would look something like: <div id="box"> <div id="template"> <div> <label for="username">Username</label> <input type="text" class="username" name="username[]" value="" / > <label for="hostname">hostname</label> <input type="text" name="hostname[]" value=""> </div> </div> <div> <label for="username">Username</label> <input type="text" class="username" name="username[]" value="paul" / > <label for="hostname">hostname</label> <input type="text" name="hostname[]" value="paul"> </div> </div> I am probably going about this the wrong way but the following test bit of javascript code run in firebug on the page does not seem to change the values of the inputs. var cp = $('#template').clone(); cp.children().children().each( function(i,d){ if( d.localName == 'INPUT' ){ $(d).val('paul'); //.css('background-color', 'red'); } }); $("#box").append(cp.html()); although if I uncomment "//.css('background-color', 'red');" the inputs will turn red.

  • Visualizing read-only folders

    - by Paul-Jan
    My application displays a folder structure in a tree. The user can browse the contents in these folders, and drag content into the folders. However, some of these folders are readonly (meaning no content can be dragged into them). I'm looking for a clear way of depicting this to the user, so they are aware which folders they can drag to before actually having to try it, i.e. hover state. Something not too alarming or interrupting (no big red crosses overlayed on top of the folder icons, for instance), preferably a recognized standard. Specifically, we are talking about an Outlook add-in showing a SharePoint folder tree here, but I'd much rather get the answer from a generic viewpoint. From the top of my head, I simply don't seem to know any applications that visually mark readonly folders.

  • How can I view multiple git diffs side by side in vim

    - by Pete Hodgson
    I'd like to be able to run a command that opens up a git diff in vim, with a tab for each file in the diff set. So if for example I've changed files foo.txt and bar.txt in my working tree and I ran the command I would see vim open with two tabs. The first tab would contain a side-by-side diff between foo.txt in my working tree and foo.txt in the repository, and the second tab would contain a side-by-side diff for bar.txt. Anyone got any ideas?

  • Placing a library part using the Revit Api

    - by ADAM
    I am using the revit api to import a family symbol. The code below is working however it loads the family into revit, and then you have to manually drag it from the familys tree or insert using the relevant family tool. Document document = commandData.Application.ActiveDocument; document.LoadFamilySymbol(fileName, name, out gotSymbol); How do i get it to the point where it is asking the user where they want it placed? (similar to when you click "load into project" when you are editing a family) so they dont have to drag it from the familys tree

  • IE page redirect hanging

    - by 08Hawkeye
    My app does a POST to my local server to create a new DOM element, comes back and should redirect to the same page with the new element. The problem is when it gets back from the server, the app hangs for almost 2 minutes before doing the redirect. I've isolated the issue to the fact that IE seems to have trouble with my tree structure of 100+ DOM elements, and I can see in HTTPWatch that it sits in a "Blocked" call for the 2 minutes before doing the redirect. Our temporary workaround is to set the inner-html of the tree structure to an empty string before submitting, thus eliminating the heavy DOM lifting, but we shouldn't need to do this (firefox has no trouble with the redirect). Question 1: Is there a better fix for this issue? Question 2: Why does ANY page care about the content before a redirect if it's going to be refreshed anyway? Thanks yall //sw

  • How to find NSOutlineView row index when using NSTreeController

    - by velocityb0y
    I'm using an NSTreeController to manage nodes for an NSOutlineView. When the user adds a new item, I create a new object and insert it: EntityViewEntityNode *newNode = [EntityViewEntityNode nodeWithName:@"New entity" entity:newObject]; // Insert at end of group // NSIndexPath *insertAt = [pathOfGroupNode indexPathByAddingIndex:[selected.children count]]; [entityCollectionTreeController insertObject:newNode atArrangedObjectIndexPath:insertAt]; Now I'd like to open the table column for edit so the user can name the new item. This seems logical: NSInteger row = [entityCollectionOutlineView rowForItem:newNode]; [entityCollectionOutlineView editColumn:0 row:row withEvent:nil select:YES]; However, row is always -1 indicating the object isn't found. Poking around reveals that the tree controller is not actually putting my objects directly in the tree, but is wrapping them in a node object of its own. Anyone have insight into how I would go about getting a row index relative to the outline view, so I can do this (without, hopefully, enumerating everything in the outline view and figuring out the mapping back to my node?)

  • Polygon with different line width (in R)

    - by Tal Galili
    Hi all, I would like to use a command like this: plot(c(1,8), 1:2, type="n") polygon(1:7, c(2,1,2,NA,2,1,2), col=c("red", "blue"), # border=c("green", "yellow"), border=c(1,10), lwd=c(1:10)) To create two triangles, with different line widths. But the polygon command doesn't seem to recycle the "lwd" parameter as it does the col or the border parameters. I would like the resulting plot to look like what the following code will produce: plot(c(1,8), 1:2, type="n") polygon(1:3, c(2,1,2), col=c("red"), # border=c("green", "yellow"), border=c(1,10), lwd=c(1)) polygon(5:7, c(2,1,2), col=c( "blue"), # border=c("green", "yellow"), border=c(1,10), lwd=c(10)) So my questions are: Is there something like polygon that does what I asked for? (If not, I would do it by creating a new polygon function that will break the original x,y by their NA's, although I am not yet sure what is the smartest way to do that...) Thanks, Tal

  • Split large text string into variable length strings without breaking words and keeping linebreaks a

    - by Frank
    I am trying to break a large string of text into several smaller strings of text and define each smaller text strings max length to be different. for example: "The quick brown fox jumped over the red fence. The blue dog dug under the fence." I would like to have code that can split this into smaller lines and have the first line have a max of 5 characters, the second line have a max of 11, and rest have a max of 20, resulting in this: Line 1: The Line 2: quick brown Line 3: fox jumped over the Line 4: red fence. Line 5: The blue dog Line 6: dug under the fence. All this in C# or MSSQL, is it possible?

  • Storing website hierarchy in Sql Server 2008

    - by Mika Kolari
    I want to store website page hierarchy in a table. What I would like to achieve is efficiently 1) resolve (last valid) item by path (e.g. "/blogs/programming/tags/asp.net,sql-server", "/blogs/programming/hello-world" ) 2) get ancestor items for breadcrump 3) edit an item without updating the whole tree of children, grand children etc. Because of the 3rd point I thought the table could be like ITEM id type slug title parentId 1 area blogs Blogs 2 blog programming Programming blog 1 3 tagsearch tags 2 4 post hello-world Hello World! 2 Could I use Sql Server's hierarchyid type somehow (especially point 1, "/blogs/programming/tags" is the last valid item)? Tree depth would usually be around 3-4. What would be the best way to achieve all this?

    How can i get the 3rd nested array (in this case the array starting with "yellow") the array looks like this: [ ["Large", ["yellow", "green", "Blue"], ["$55.00", "$55.00", "$55.00"] ["Medium", ["yellow", "green", "Blue", "Red"], ["$55.00", "$55.00", "$55.00", "$55.00"] ] ["small", ["yellow", "green", "Blue", "Red"], ["$55.00", "$55.00", "$55.00", "$55.00"] ] ] I am trying to get to the ["yellow", "green", "Blue"] array's length and loop to get the values for(i=0; colorNSize.dataArray[0][0][1].length<i; i++){ alert(colorNSize.dataArray[colorNSize.Sizeindex][0][0][i])// alert's nothing } It actually alerts the length of "Large" which is "5" is there a limit for nested arrays? Can this be done?
