• displaying a saved buffer in OpenGL ES

  - by Adam

  Hi everyone, So basically I have a screenshot that I've saved that I want to later display on the screen. I've saved it with: glReadPixels(0, 0, self.bounds.size.width, self.bounds.size.height, GL_RGBA, GL_UNSIGNED_BYTE, savedBuffer); And later I'm trying to write it to the screen with: GLuint RenderedTex; glGenTextures(1, &RenderedTex); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, RenderedTex); glTexImage2D (GL_TEXTURE_2D, 0, GL_RGBA, self.bounds.size.width, self.bounds.size.height, 0, GL_RGBA, GL_UNSIGNED_BYTE, savedBuffer); glDisable(GL_TEXTURE_2D); I'm pretty new to OpenGL so I don't know if I'm doing things right... actually I know I'm not, because nothing shows up. Also not sure how to dispose of the texture when I'm done with it. Anyone know the correct way to do this? Edit: I think I might be having a problem loading the texture because it's not a power of 2, it's 320x480... also, I think this code is just loading the texture, but not drawing it, I'd need a call to glDrawArrays(GL_TRIANGLE_STRIP, 0, 4) in there somewhere...

• Hashtable resizing leaks memory

  - by thpetrus

  I wrote a hashtable and it basically consists of these two structures: typedef struct dictEntry { void *key; void *value; struct dictEntry *next; } dictEntry; typedef struct dict { dictEntry **table; unsigned long size; unsigned long items; } dict; dict.table is a multidimensional array, which contains all the stored key/value pair, which again are a linked list. If half of the hashtable is full, I expand it by doubling the size and rehashing it: dict *_dictRehash(dict *d) { int i; dict *_d; dictEntry *dit; _d = dictCreate(d->size * 2); for (i = 0; i < d->size; i++) { for (dit = d->table[i]; dit != NULL; dit = dit->next) { _dictAddRaw(_d, dit); } } /* FIXME memory leak because the old dict can never be freed */ free(d); // seg fault return _d; } The function above uses the pointers from the old hash table and stores it in the newly created one. When freeing the old dict d a Segmentation Fault occurs. How am I able to free the old hashtable struct without having to allocate the memory for the key/value pairs again?

• Pygame Sprite/Font rendering issues

  - by Grimless

  Hey guys. Here's my problem: I have a game class that maintains a HUD overlay that has a bunch of elements, including header and footer background sprites. Everything was working fine until I added a 1024x128 footer sprite. Now two of my text labels will not render, despite the fact that they DO exist in my Group and self.elements array. Is there something I'm missing? When I take out the footerHUDImage line, all of the labels render correctly and everything works fine. When I add the footerHUDImage, two of the labels (the first two) no longer render and the third only sometimes renders. HELP PLEASE! Here is the code: class AoWHUD (object): def __init__(self, screen, delegate, dataSource): self.delegate = delegate self.dataSource = dataSource self.elements = [] headerHudImage = KJRImage("HUDBackground.png") self.elements.append(headerHudImage) headerHudImage.userInteractionEnabled = True footerHUDImage = KJRImage("ControlsBackground.png") self.elements.append(footerHUDImage) footerHUDImage.rect.bottom = screen.get_rect().height footerHUDImage.userInteractionEnabled = True lumberMessage = "Lumber: " + str(self.dataSource.lumber) lumberLabel = KJRLabel(lumberMessage, size = 48, color = (240, 200, 10)) lumberLabel.rect.topleft = (_kSpacingMultiple * 0, 0) self.elements.append(lumberLabel) stoneMessage = "Stone: " + str(self.dataSource.stone) stoneLabel = KJRLabel(stoneMessage, size = 48, color = (240, 200, 10)) stoneLabel.rect.topleft = (_kSpacingMultiple * 1, 0) self.elements.append(stoneLabel) metalMessage = "Metal: " + str(self.dataSource.metal) metalLabel = KJRLabel(metalMessage, size = 48, color = (240, 200, 10)) metalLabel.rect.topleft = (_kSpacingMultiple * 2, 0) self.elements.append(metalLabel) foodMessage = "Food: " + str(len(self.dataSource.units)) + "/" + str(self.dataSource.food) foodLabel = KJRLabel(foodMessage, size = 48, color = (240, 200, 10)) foodLabel.rect.topleft = (_kSpacingMultiple * 3, 0) self.elements.append(foodLabel) self.selectionSprites = {32 : pygame.image.load("Selected32.png").convert_alpha(), 64 : pygame.image.load("Selected64.png")} self._sprites_ = pygame.sprite.Group() for e in self.elements: self._sprites_.add(e) print self.elements def draw(self, screen): if self.dataSource.resourcesChanged: lumberMessage = "Lumber: " + str(self.dataSource.lumber) stoneMessage = "Stone: " + str(self.dataSource.stone) metalMessage = "Metal: " + str(self.dataSource.metal) foodMessage = "Food: " + str(len(self.dataSource.units)) + "/" + str(self.dataSource.food) self.elements[2].setText(lumberMessage) self.elements[2].rect.topleft = (_kSpacingMultiple * 0, 0) self.elements[3].setText(stoneMessage) self.elements[3].rect.topleft = (_kSpacingMultiple * 1, 0) self.elements[4].setText(metalMessage) self.elements[4].rect.topleft = (_kSpacingMultiple * 2, 0) self.elements[5].setText(foodMessage) self.elements[5].rect.topleft = (_kSpacingMultiple * 3, 0) self.dataSource.resourcesChanged = False self._sprites_.draw(screen) if self.delegate.selectedUnit: theSelectionSprite = self.selectionSprites[self.delegate.selectedUnit.rect.width] screen.blit(theSelectionSprite, self.delegate.selectedUnit.rect)

• Moving UIScrollView in App

  - by jsetting32

  Currently, I am attempting to create the same effect as Yahoo! Weather's App where the vital day information is at the bottom of the page on the top of a UIScrollView, that's contained by a UIView. I am having a hard time thinking about how this is going to happen or how I should implement this. If the user taps on the top of the UIScrollView which is located near the bottom of the laoded UIView, and starts to scroll up (/), the UIScrollView's frame should be moved to the TOP of the current UIView's frame. So the UIScrollView's y-value should change to UIView's (self.view.frame.origin.y) if the user starts scrolling UP on the UIScrollView which is located on the UIView's y-pixel ~280. Here's what the UIViewController should look like in the beginning of loading the ViewController... Then once the user slides his finger from the bottom to the top of the screen... this should happen........ And when the user scrolls to the top of the UIScrollView with all the content within it... the view should go back to the start picture shown... How is this done? I was thinking several UIGestureRecognizer's and Instantiating the UIscrollview at the lower part of the UIView... _weatherView = [[UIScrollView alloc] initWithFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y + 250, self.view.bounds.size.width, self.view.bounds.size.height - 44)]; _weatherView.contentSize = CGSizeMake(self.view.bounds.size.width, self.view.bounds.size.height * 4); _weatherView.backgroundColor = [UIColor clearColor]; [self.view addSubview:_weatherView]; The adding some UIGestureRecognizer delegate method.... But anyone have any ideas on the UIGestureRecognizer delegate method? And how it should be implemented? I can write the psuedo-code but I am having problems finding the delegate methods :P Thank you!!! ---- Break Time.... :)

• how to set the output image use com.android.camera.action.CROP

  - by adi.zean

  I have code to crop an image, like this : public void doCrop(){ Intent intent = new Intent("com.android.camera.action.CROP"); intent.setType("image/"); List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent,0); int size = list.size(); if (size == 0 ){ Toast.makeText(this, "Cant find crop app").show(); return; } else{ intent.setData(selectImageUri); intent.putExtra("outputX", 300); intent.putExtra("outputY", 300); intent.putExtra("aspectX", 1); intent.putExtra("aspectY", 1); intent.putExtra("scale", true); intent.putExtra("return-data", true); if (size == 1) { Intent i = new Intent(intent); ResolveInfo res = list.get(0); i.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name)); startActivityForResult(i, CROP_RESULT); } } } public void onActivityResult (int requestCode, int resultCode, Intent dara){ if (resultCode == RESULT_OK){ if (requestCode == CROP_RESULT){ Bundle extras = data.getExtras(); if (extras != null){ bmp = extras.getParcelable("data"); } File f = new File(selectImageUri.getPath()); if (f.exists()) f.delete(); Intent inten3 = new Intent(this, tabActivity.class); startActivity(inten3); } } } from what i have read, the code intent.putExtra("outputX", 300); intent.putExtra("outputY", 300); is use to set the resolution of crop result, but why i can't get the result image resolution higer than 300x300? when i set the intent.putExtra("outputX", 800); intent.putExtra("outputY", 800); the crop function has no result or crash, any idea for this situation? the log cat say "! ! ! FAILED BINDER TRANSACTION ! ! !

• create board for game with events support in WPF

  - by netmajor

  How can I create board for simple game, looks like for chess,but user could dynamically change number of column and rows? In cells I could insert symbol of pawn, like small image or just ellipse or rectangle with fill. This board should have possibility add and remove pawn from cells and move pown from one cell to another. My first idea was Grid. I do it in code behind, but it's hurt to implement events or everything in runtime create board :/ int size = 12; Grid board = new Grid(); board.ShowGridLines = true; for (int i = 0; i < size;i++ ) { board.ColumnDefinitions.Add(new ColumnDefinition()); board.RowDefinitions.Add(new RowDefinition()); } //komputer Rectangle ai = new Rectangle(); ai.Height = 20; ai.Width = 20; ai.AllowDrop = true; ai.Fill = Brushes.Orange; Grid.SetRow(ai, 0); Grid.SetColumn(ai,0); //czlowiek Rectangle hum = new Rectangle(); hum.Height = 20; hum.Width = 20; hum.AllowDrop = true; hum.Fill = Brushes.Green; Grid.SetRow(hum,size); Grid.SetColumn(hum,size); board.Children.Add(ai); board.Children.Add(hum); this.Content = board; It's a way to do this dynamically col and row change in XAML ? It's better way to implement that board create and implement events on move pawn from one cell to another ?

• UIImageView Centering Problem.

  - by sagar

  To understand my problem let's follow this steps. Open - XCode - New Project - View based application. Open View Controller.xib file. Drag an image-view into viewController's view. Place that image view on center of viewController's view. Apply size of 125x125 to image-view. Take any image with dimension of 320 width & 460 height. Drag that image into your application resources directory. Now, Again back to .xib File & select image-view Set image (which is in your resources) to image-view Set Image-view Mode to - Center Ok. Let me explain the situation now. after performing all above steps - image-view has an image which is larger than image-view's size. However, Image-view places that image on center & in View controller image-view is looking proper ( not scaled ). But When you run your application, image-view will be displayed in size of 320x460. ( but it is not actually scaled. ) Now, I can't find the reason, why interface builder is displaying something else & simulator/iphone is displaying something else ? My Query. I want the image's center portion within image-view no matter what image size is. Thanks in advance for sharing your knowledge. Sagar.

• A simple way to put a UIImage in a UIButton

  - by Alice

  I have a UIButton in my iPhone app. I set its size to 100x100. I have an image that is 400x200 that I wish to display in the button. The button STILL needs to stay at 100x100... and I want the image to downsize to fit... but keep the correct aspect ratio. I thought that's what "Aspect Fit" was used for. Do I include my image with setImage, or setBackgroundImage? Do I set AspectFit for the button? or the image? or the background image? (I need the smaller images to INCREASE in size. While larger images should DESCREASE in size. Always keeping the button at 100x100.) I've tried countless combinations of all of the above... and I just can't seem to get everything to work at the same time: Don't change the button's size of 100x100. Don't destroy the image's aspect ratio. Always increase small images to fit the button. Always decrease large images to fit the button. Never clip any of the image edges. Never require the "put UIButtons over all your UIimages" hack. Don't require everyone to upgrade to v4.2.1 just to use new framework methods. I see so many apps, with so many fully-working image-buttons... that I can't believe I can't figure out this very simple, very common thing. Ugh.

• How Can I Compress Texture in OpenGL on iPhone/iPad?

  - by nonamelive

  Hi, I'm making an iPad app which needs OpenGL to do a flip animation. I have a front image texture and a back image texture. Both the two textures are screenshots. // Capture an image of the screen UIGraphicsBeginImageContext(view.bounds.size); [view.layer renderInContext:UIGraphicsGetCurrentContext()]; image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); // Allocate some memory for the texture GLubyte *textureData = (GLubyte*)calloc(maxTextureSize*4, maxTextureSize); // Create a drawing context to draw image into texture memory CGContextRef textureContext = CGBitmapContextCreate(textureData, maxTextureSize, maxTextureSize, 8, maxTextureSize*4, CGImageGetColorSpace(image.CGImage), kCGImageAlphaPremultipliedLast); CGContextDrawImage(textureContext, CGRectMake(0, maxTextureSize-size.height, size.width, size.height), image.CGImage); CGContextRelease(textureContext); // ...done creating the texture data [EAGLContext setCurrentContext:context]; glGenTextures(1, &textureToView); glBindTexture(GL_TEXTURE_2D, textureToView); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, maxTextureSize, maxTextureSize, 0, GL_RGBA, GL_UNSIGNED_BYTE, textureData); // free texture data which is by now copied into the GL context free(textureData); Each of the texture takes up about 8MB memory, which is unacceptable for an iPhone/iPad app. Could anyone tell me how can I compress the texture to reduce the memory. I'm a complete newbie to OpenGL. Any help would be appreciated!

• Match subpatterns in any order

  - by Yaroslav

  I have long regexp with two complicated subpatters inside. How i can match that subpatterns in any order? Simplified example: /(apple)?\s?(banana)?\s?(orange)?\s?(kiwi)?/ and i want to match both of apple banana orange kiwi apple orange banana kiwi It is very simplified example. In my case banana and orange is long complicated subpatterns and i don't want to do something like /(apple)?\s?((banana)?\s?(orange)?|(orange)?\s?(banana)?)\s?(kiwi)?/ Is it possible to group subpatterns like chars in character class? UPD Real data as requested: 14:24 26,37 Mb 108.53 01:19:02 06.07 24.39 19:39 46:00 my strings much longer, but it is significant part. Here you can see two lines what i need to match. First has two values: length (14 min 24 sec) and size 26.37 Mb. Second one has three values but in different order: size 108.53 Mb, length 01 h 19 m 02 s and date June, 07 Third one has two size and length Fourth has only length There are couple more variations and i need to parse all values. I have a regexp that pretty close except i can't figure out how to match patterns in different order without writing it twice. (?<size>\d{1,3}\[.,]\d{1,2}\s+(?:Mb)?)?\s? (?<length>(?:(?:01:)?\d{1,2}:\d{2}))?\s* (?<date>\d{2}\.\d{2}))? NOTE: that is only part of big regexp that forks fine already.

• Make an empty DIV height and width of its container

  - by Olly F

  My HTML currently contains a background image that stretches with the viewport. Within that, I plan to place a div that stretches to the height and width of the viewport and has black background colour at 50% opacity. I've set the div to be 100% width and height. The div is not stretching and I can't figure out why! HTML: <!DOCTYPE HTML> <html lang="en"> <head> <title>Tester</title> <meta charset="UTF-8"/> <style type="text/css"> html { background: url(http://cjpstudio.com/wp-content/uploads/2011/12/cityrock1.jpg) no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover; } #background-color { width: 100%; height: 100%; background-color: #000000; } </style> </head> <body> <div id="background-color"> </div> </body>

• ContentPresenter within ControlTemplate cannot change attached dependency property

  - by happyclicker

  Why does the following simplified code not set the font-size of the TextBlock to 50? <Window.Resources> <ControlTemplate TargetType="ContentControl" x:Key="Test"> <ContentPresenter TextBlock.FontSize="50" /> </ControlTemplate> </Window.Resources> <Grid> <ContentControl Template="{StaticResource Test}"> <TextBlock>Test should be rendered big</TextBlock> </ContentControl> </Grid> If I change the value of the FontSize property, visual studio shows me the text in the size I want. After compiling or executing the app, the size of the textblock is always reset to its default size. I have also tested various versions with styles and embedded resources but I end always in the situation that I cannot set attached dp's from within a ControlTemplate that contains a ContentPresenter. Is this by design?

• MongoDB complex MapReduce of video logs

  - by Justin Hourigan

  I have a dataset from video streaming logs. Each video is identified by a FileGUID. The log entries record the FileGUID, the fragment of the video watched and the bandwidth it was watched at. I would like to create a mapreduce outputting, for each video, a count for fragments both total and for each bandwidth. Ideally it would look like; {"FileGUID":"50acb3a5796634df0e073285", { "1":{"total":76, "0832":34, "1028":42}, "2":{"total":42, "0832":28, "1028":14}, ... } } Is this possible with one mapreduce or is it a multi-step process, or should I use a different method? Here is a sample of the data. { "_id": ObjectId("50acb3a5796634df0e073285"), "IP": "46.7.1.88", "DateTime": ISODate("2012-10-24T22:59:57.0Z"), "FileGUID": "8cdde821fb934a6da7c125a012a26612", "Bandwidth": NumberInt(1028), "Segment": NumberInt(1), "Fragment": NumberInt(237), "Status": NumberInt(200), "Size": NumberInt(576790), "UserAgent": "Mozilla\/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko\/20100101 Firefox\/16.0" } { "_id": ObjectId("50acb3a5796634df0e073284"), "IP": "46.7.1.88", "DateTime": ISODate("2012-10-24T22:59:52.0Z"), "FileGUID": "8cdde821fb934a6da7c125a012a26612", "Bandwidth": NumberInt(1028), "Segment": NumberInt(1), "Fragment": NumberInt(236), "Status": NumberInt(200), "Size": NumberInt(577100), "UserAgent": "Mozilla\/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko\/20100101 Firefox\/16.0" } { "_id": ObjectId("50acb3a5796634df0e073283"), "IP": "46.7.1.88", "DateTime": ISODate("2012-10-24T22:59:47.0Z"), "FileGUID": "8cdde821fb934a6da7c125a012a26612", "Bandwidth": NumberInt(0832), "Segment": NumberInt(1), "Fragment": NumberInt(234), "Status": NumberInt(200), "Size": NumberInt(576664), "UserAgent": "Mozilla\/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko\/20100101 Firefox\/16.0" } { "_id": ObjectId("50acb3a5796634df0e073282"), "IP": "46.7.1.88", "DateTime": ISODate("2012-10-24T22:59:42.0Z"), "FileGUID": "8cdde821fb934a6da7c125a012a26612", "Bandwidth": NumberInt(0832), "Segment": NumberInt(1), "Fragment": NumberInt(233), "Status": NumberInt(200), "Size": NumberInt(575692), "UserAgent": "Mozilla\/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko\/20100101 Firefox\/16.0" }

• How to traverse table in Jquery and add a class?

  - by SWL

  I have a simple table of two rows. The first column is required, but the others are not; however, I would like them to be required in pairs. So if the user enters a value for Quantity3, then Size3 should also now be required. As a fiddle: http://jsfiddle.net/NaRts/7/ <tr> <td><input name="qty1[492]" class="qty required" type="text"></td> <td><input name="qty2[492]" class="qty" type="text"></td> <td><input name="qty3[492]" class="qty" type="text"></td> </tr><tr> <td><input name="size1[492]" type="text" class="size required" ></td> <td><input name="size2[492]" type="text" class="size" ></td> <td><input name="size3[492]" type="text" class="size" ></td> </tr> And the simple jQuery I have is: $('.qty').keyup(function() { var s = $(this).attr('name'); // = qty3[418] var qtyID = s.replace(/[^1-9\[\]]/g, ""); // = 3[418] var SizeID = "size" + qtyID; var $sizeInput = $(this).closest('tr').next().find(SizeID); $sizeInput.css('background-color', 'green'); $sizeInput.addClass('required'); //I tried this too but it didn't work //$(this).parent().find(SizeID).addClass('required'); });? ? Any help is much appreciated.

• Concept: Is mongo right for applying schemas?

  - by Jan

  I am currently in charge of checking wether it is valuable for one of our upcoming products to be developed on mongo. Without going too much into detail, I'll try to explain, what the app does. The app simply has "entities". These entities are technical stuff, like cell phones, TVs, Laptops, tablet pcs, and so forth. Of course, a cell phone has other attributes than a Tablet PCs and a Laptop has even other attributes, like RAM, CPU, display size and so on. Now I want to have something that we wanna call a scheme: We define that we need to have saved the display size, amount of ram size of flash devices, processor type, processor speed and so on for tablet pcs. For cell phone we might save display size, GSM, Edge, 3g, 4g, processor, ram, touch screen technology, bla bla bla. I think you got it :) What I want to realize is, that each "category" has a schema and when one of the system's users enters a new product (let's say the new iphone 4), the app constructs the form to be filled out with the appropriate attributes. So far it sounds nice and should not be a problem with mongo. But now the tough for which I could not find a clean solution.... An attribute modeled in mongo looks like: { _id: 1234456, name: "Attribute name", type: 0, "description" } But what to do, if i need this attribute in several languages, like: { en: {name: "Attribute name", type: 0, "description"}, de: {name: "Name des Attributs, type: 0, "Beschreibung"} } I also need to ensure that the german attribute gets updated as soon as the english gets updated, for instance when type changes from 0 to 1. Any ideas on that?

• Fibonacci in C works great with 1 - 18 but 19 does nothing at all...

  - by shevron

  Yeah right... we are forced to programm some good old C at our university... ;) So here's my problem: We got the assignment to program a little program that show a fibonacci sequence from 1 to n 1 to 18 works great. But from 19 the program does nothing at all and just exit as it's done. I can not find the error... so please give me a hint. :) #include #include #include #include int main(int argc, char **argv) { pid_t pid; int fib[argc]; int i, size; size = strtol(argv[1], NULL, 0L); fib[0] = 0; fib[1] = 1; pid = fork(); printf("size = %d \n", size); if(pid == 0){ for(i = 2; i 0){ // Parent, because pid 0 wait(NULL); printf("\n"); exit(1); } } Thanks already!

• This code is not submitting to a form? Why

  - by Ankur

  Since I am using get I expect to see the submitted values appended to the queryString but instead all I see is the URL of the servlet being called with nothing added at the end. <form id="editClassList" name="editClassList" method="get" action="EditClassList"> <% HashMap<Integer,String> classes = new HashMap<Integer,String>(); classes = (HashMap<Integer,String>) request.getAttribute("classes"); %> <% if(classes.size()==0){ %> <label><input class="small-link" type="text" id="add-this-class" size="42" value="" /></label> <% } %> <% Set<Integer> classIds = new HashSet<Integer>(); classIds = classes.keySet(); Iterator<Integer> itr = classIds.iterator(); while(itr.hasNext()){ int nextId = (Integer)itr.next(); %> <label><input class="small-link" type="text" id="<% out.print(nextId); %>" size="42" value="<% out.print(classes.get(nextId)); %>" /> </label> <img id="add-class" src="images/add.png" width="16" height="16" /><br /> <label><input class="small-link" type="text" id="class-to-add" size="42" value="" /></label> <% } %> <label><input type="submit" id="save-class-btn" value="Save Class(es)" /></label> </form>

• How to Alphabetize a CSS file in Vim

  - by Kev

  I get a CSS file: div#header h1 { z-index: 101; color: #000; position: relative; line-height: 24px; margin-right: 48px; border-bottom: 1px solid #dedede; font-size: 18px; } div#header h2 { z-index: 101; color: #000; position: relative; line-height: 24px; margin-right: 48px; border-bottom: 1px solid #dedede; font-size: 18px; } I want to Alphabetize lines between the {...} div#header h1 { border-bottom: 1px solid #dedede; color: #000; font-size: 18px; line-height: 24px; margin-right: 48px; position: relative; z-index: 101; } div#header h2 { border-bottom: 1px solid #dedede; color: #000; font-size: 18px; line-height: 24px; margin-right: 48px; position: relative; z-index: 101; } I map F7 to do it nmap <F7> /{/+1<CR>vi{:sort<CR> But I need to press F7 over and over again to get the work done. If the CSS file is big, It's time-consuming & easily get bored. I want to get the cmds piped. So that, I only press F7 once! Any idea? thanks!

• reading a file of unknown length with a function

  - by Faken

  I'm trying to write a short function that will let me quickly read in a file of unknown size and return pointer to the array of data and the length of that array but it seems my code isn't working. What am i doing wrong? int readIn(int* pointer, param parameters, string description) { string fileName = parameters.fileName + " " + description + ".bin"; ifstream readFile; readFile.open(fileName.c_str(), ios::in|ios::binary|ios::ate); int size = readFile.tellg(); int length = size / 4; int* output = new int [length]; readFile.seekg (0, ios::beg); readFile.read(reinterpret_cast<char*>(output), (size)); readFile.close(); pointer = output; // link new array with the pointer return length; } and in the main function: int* testList; int numEntries = readIn(testList, parameters, "test"); I end up with an error saying that my testList variable was used and not initialized. What am i doing wrong?

• PyGTK: Manually render an existing widget at a given Rectangle? (TextView in a custom CellRenderer)

  - by NicDumZ

  Hello! I am trying to draw a TextView into the cell of a TreeView. (Why? I would like to have custom tags on text, so they can be clickable and trigger different actions/popup menus depending on where user clicks). I have been trying to write a customized CellRenderer for this purpose, but so far I failed because I find it extremely difficult to find generic documentation on rendering design in gtk. More than an answer at the specific question (that might be hard/not doable, and I'm not expecting you to do everything for me), I am first looking for documentation on how a widget is rendered, to understand how one is supposed to implement a CellRenderer. Can you share any link that explains, either for gtk or for pygtk, the rendering mechanism? More specifically: size allocation mechanism (should I say protocol?). I understand that a window has a defined size, and then queries its children, saying "my size is w x h, what would be your ideal size, buddy?", and then sometimes shrinks children when all children cant fit together at their ideal sizes. Any specific documentation on that, and on particular on when this happens during rendering? How are rendered "builtin" widgets? What kind of methods do they call on Widget base class? On the parent Window? When? Do they use pango.Layout? can you manually draw a TextView onto a pango.Layout object? This link gives an interesting example showing how you can draw content in a pango.Layout object and use it in a CellRenderer. I guess that I could adapt it if only I understood how TextView widget are rendered. Or perhaps, to put it more simply: given an existing widget instance, how does one render it at a specific gdk.Rectangle? Thanks a lot.

• How do I resize table view after resizing it's footer?

  - by Pedro

  I have a UITableView with header & footer added with code following the pattern shown in Apple's recipes example so the code for the footer is... if (tableFooterView == nil) { [[NSBundle mainBundle] loadNibNamed:@"DetailFooterView" owner:self options:nil]; self.tableView.tableFooterView = tableFooterView; } The footer NIB contains nothing more than a UITextView & I set text & resize with... CGSize size = [footerText sizeWithFont:[footerTextView font] constrainedToSize:CGSizeMake(304.0, 500.0)]; CGRect frame = CGRectMake(8.0, 0.0, size.width, size.height + 24.0); footerTextView.frame = frame; footerTextView.text = footerText; [tableFooterView sizeToFit]; That all works however I can't get the UITableView to resize around the resized footer. If I set the original size of the footer for any possible text I have a big whitespace in most cases. If I set it smaller then I can push the view up to see the whole text but it bounces back on release. I've tried [[self view] sizeToFit]; but that doesn't work. Can anyone fill me in? Cheers & TIA, Pedro :)
