• Dual monitor not working completely in 12.10 after upgrade

  - by Mark Baldridge

  At 12.04, dual monitors worked perfectly. After upgrading to 12.10, the primary monitor works, the second monitor only partly works. I am sure there is some difference between the releases that I have missed setting properly. System settings - Displays show both correctly as Acer 22" monitors at 1680x1050 (16:10). An icon on monitor 2 is present, but elongated; almost an artifact, since other icons on the primary screen are absent, but this one icon is there on th second monitor. Selecting the icons on both screens exist. Painting is weird on monitor 2. Launcher exists and works on both screens, but even with sticky edges off, the cursor stops at the left edge of monitor 2. Clicking on text editor on screen 2 launcer will launch gedit there. If I drag it, it leaves a trail of after images like repaint is failing. If I drive the cursor on the launcher, the help tags like "LibreOffice Writer" appear, but stay on screen unless I drag the active gedit window over them. Then part of the help bubbles are overwritten, leaving behind after images of the gedit window on screen. What is really fascinating is that the System settings - Displays is now ignoring monitor selection, after allowing it earlier. Just before this, the help popup which said "Select a monitor to change its properties; drag to rearrange its placement" actually let me do that. Maybe a trick of where I grab the edge of the monitor in the Displays setting. I just found a working handle. When I drag monitor 1 to the right of monitor 2, "Apply" and confirm, both monitors work normally (although the right monitor lets the cursor slide off the right edge onto the left edge of monitor 1 - which sounds correct). Painting of windows does not leave an after image. However, success is only temporary. The setting survives the reboot, but painting on the left monitor, now monitor 2, now replicates the issues from before. The after image of the gedit window and the small window for "Are you sure you want to close all programs and restart the computer?" are still on monitor 2 (on the left now), even though they are not real windows, nor do they have processes behind them. Curiously, in Displays, the "green" monitor on the left in the display window is matched by the right monitor color in the monitor upper left corner. Probably makes sense as the one on the right is now monitor 1. If I repeat the "drag the left monitor to the right of the right monitor on the "Displays" window, things are oriented properly, with no display artifacts as I drag windows around either screen. Also the description bubbles that pop up are overwritten on both screens, so none of those artifacts either. This goodness does not survive a reboot, however. Have not tried logging out and back in. All of this after positing that the motherboard VGA and HDMI ports could have been the issue. So, I installed an e-GeForce 7600 GT Dual DVI (I know the web thinks it is not DVI, but VGA, but the connectors are DVI). No change to the weird behavior. The good parts continue to work, the weirdness also works, and swapping monitor positions seems to cure the issue. So, is there a setting I have missed? Given "swapping" monitor 1 and 2 on the System Settings... - Displays makes it work, just not across boot, I suspect so.

• Is the Leptonica implementation of 'Modified Median Cut' not using the median at all?

  - by TheCodeJunkie

  I'm playing around a bit with image processing and decided to read up on how color quantization worked and after a bit of reading I found the Modified Median Cut Quantization algorithm. I've been reading the code of the C implementation in Leptonica library and came across something I thought was a bit odd. Now I want to stress that I am far from an expert in this area, not am I a math-head, so I am predicting that this all comes down to me not understanding all of it and not that the implementation of the algorithm is wrong at all. The algorithm states that the vbox should be split along the lagest axis and that it should be split using the following logic The largest axis is divided by locating the bin with the median pixel (by population), selecting the longer side, and dividing in the center of that side. We could have simply put the bin with the median pixel in the shorter side, but in the early stages of subdivision, this tends to put low density clusters (that are not considered in the subdivision) in the same vbox as part of a high density cluster that will outvote it in median vbox color, even with future median-based subdivisions. The algorithm used here is particularly important in early subdivisions, and 3is useful for giving visible but low population color clusters their own vbox. This has little effect on the subdivision of high density clusters, which ultimately will have roughly equal population in their vboxes. For the sake of the argument, let's assume that we have a vbox that we are in the process of splitting and that the red axis is the largest. In the Leptonica algorithm, on line 01297, the code appears to do the following Iterate over all the possible green and blue variations of the red color For each iteration it adds to the total number of pixels (population) it's found along the red axis For each red color it sum up the population of the current red and the previous ones, thus storing an accumulated value, for each red note: when I say 'red' I mean each point along the axis that is covered by the iteration, the actual color may not be red but contains a certain amount of red So for the sake of illustration, assume we have 9 "bins" along the red axis and that they have the following populations 4 8 20 16 1 9 12 8 8 After the iteration of all red bins, the partialsum array will contain the following count for the bins mentioned above 4 12 32 48 49 58 70 78 86 And total would have a value of 86 Once that's done it's time to perform the actual median cut and for the red axis this is performed on line 01346 It iterates over bins and check they accumulated sum. And here's the part that throws me of from the description of the algorithm. It looks for the first bin that has a value that is greater than total/2 Wouldn't total/2 mean that it is looking for a bin that has a value that is greater than the average value and not the median ? The median for the above bins would be 49 The use of 43 or 49 could potentially have a huge impact on how the boxes are split, even though the algorithm then proceeds by moving to the center of the larger side of where the matched value was.. Another thing that puzzles me a bit is that the paper specified that the bin with the median value should be located, but does not mention how to proceed if there are an even number of bins.. the median would be the result of (a+b)/2 and it's not guaranteed that any of the bins contains that population count. So this is what makes me thing that there are some approximations going on that are negligible because of how the split actually takes part at the center of the larger side of the selected bin. Sorry if it got a bit long winded, but I wanted to be as thoroughas I could because it's been driving me nuts for a couple of days now ;)

• How to get the height of an image and apply that height to a div? [migrated]

  - by Mick79

  I am building a mobile web app and I'm using jquerytools slider on it. i want te slider to show (in proper ratio) across all mobile devices so width of the images is 100% and height is auto in css. However as all the elements are floated and jquerytools slider requires the position be set to absolute, the containing div (#header) doesn't stretch to fit the content. I am trying to use jquery to get the height of the height of the img and apply that height to the header.... however I am having no luck. CSS: #header{ width:100%; position:relative; z-index: 20; /* box-shadow: 0 0 10px white; */ overflow: auto; } .scrollable { position:relative; overflow:hidden; width: 100%; height: 100%; /* box-shadow: 0 0 20px purple; */ /* height:198px; */ z-index: 20; overflow: auto; } .scrollable .items { /* this cannot be too large */ width:1000%; position:absolute; clear:both; /* box-shadow: 0 0 30px green; */ } .items div { float:left; width:10%; height:100%; } /* single scrollable item */ .scrollable img { /* float:left; */ width:100%; height: auto; /* height:198px; */ } /* active item */ .scrollable .active { border:2px solid #000; position:relative; cursor:default; } HTML <div id=header><!-- root element for scrollable --> <div class="scrollable" id="scrollable"> <!-- root element for the items --> <div class="items"> <div> <img src="img/img2.jpg" /> </div> <div> <img src="img/img1.jpg" /> </div> <div> <img src="img/img3.jpg" /> </div> <div> <img src="img/img4.jpg" /> </div> <div> <img src="img/img6.jpg" /> </div> </div><!-- items --> </div><!-- scrollable --> </div><!-- header -->

• I am not satisfied with my career and accomplished nothing in my life. what should I do now [on hold]

  - by user2906155

  After my complete my College education I got chance to work on software programming. I work on few software and now nothing make me feel good. I don't like web-programming. Can't have too much mind to play with other people in team a designer or a senior. it's totally time wasting for me. We do integration without any source code control. copy through pen drive. I write in too many language for web-programming but know nothing about any language specially. I don't like to have a BOSS. I would like to do something on my own. From last 3 year I thing I will got a better job but I am unable to get it. I am not good at Programming nor my English is native. I have a big list for pay then my salary. I have problem with nothing. my atmosphere is about illiterate people. they abuse 24 hours a day. this thing make me sick. people watch CRIME patrol my home (watching rape in TV because it's happen to someone). I do my work from home. I don't like to live in my state. All state is one of the biggest illiterate state of my country. Once I apply for a Job in China and it's look like I can get thing Job but I don't get it. My family doesn't want me to settle anywhere else. I told my family 4 time a day that I can't live in this worst situation. Everyone (including the person who I work for) tell me that you can do it only you have money. Now I really don't know how to make money. My job not allow me to work for anyone. My productivity going down since I don't learn anything new. I thing if this happen to me for next 2 year I don't have any knowledge more then a peon. I hate it. When I was in other city then I see that if I spent 7 days their all my 7 days going better. even I go for travelling in green places then I like it. but all I hate it where I work for. When I work on other city then I see my productivity are improved and I don't hate my work. I listen a song "If you don't your love what are you doing it for". I seriously don' t know what I still live here because this place gave me nothing but depression and trouble. for people I clear that I don't belong to RICH or middle class family. All I got is doing something on my own or help of someone. affording a rental place make my run on footpath. All I save in one month is just 10$ (approximately) (actually I afford some guys's education now). Can a programmer live worst life like this. I really not happy. Today is a festival in India and I don't celebrate it because I really hate myself. I want to do suicide. someone guide me how to start solving this headache

• Rendering a UIWebView in drawRect with loadHTMLString

  - by Nick Weaver

  Hello there, I am having a problem with UIWebView. I'd like to render my own html code in it. When I add a webview as a subview and put in some html code it renders just fine. When it gets down to some optimized drawing of tableview cell with the drawRect method the problem pops up. Drawing UIView descendants works pretty well this way. It's even possible to load a URL with the loadRequest method, setting the delegate, conforming to the UIWebViewDelegate protocol and redrawing the table cell with setNeedsDisplay when webViewDidFinishLoad is called. It does show, but when it comes to loadHTMLString, nothing shows up, only a white rect. Due to performance reasons I have to do the drawing in the drawRect method. Any ideas? Thanks in advance Nick Example snippet code for the html code being loaded by a UIWebView: NSString *html = @"<html><head><title>My fancy webview</title></head><body style='background-color:green;'><p>It somehow seems<h2 style='color:black;'>this does not show up in drawRect</h2>!</p></body></html>"; [webView loadHTMLString:html baseURL:nil]; Snippet for the drawRect method: - (void)drawRect:(CGRect)aRect { CGContextRef context = UIGraphicsGetCurrentContext(); [[webView layer] renderInContext:context]; }

• Subclassing UINavigationBar ... how do I use it in UINavigationController?

  - by funkadelic

  Hi, I wanted to subclass UINavigationBar (to set a custom background image & text color) and use that for all the navigation bars in my app. Looking at the API docs for UINavigationController, it looks like navigationBar is read-only: @property(nonatomic, readonly) UINavigationBar *navigationBar Is there a way to actually use a custom UINavigationBar in my UIViewControllers? I know that other apps have done custom navigation bars, like flickr: Here is my UINavigationBar subclass: #import <UIKit/UIKit.h> @interface MyNavigationBar : UINavigationBar <UINavigationBarDelegate> { } @end the implementation #import "MyNavigationBar.h" @implementation MyNavigationBar - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)drawRect:(CGRect)rect { // override the standard background with our own custom one UIImage *image = [[UIImage imageNamed:@"navigation_bar_bgd.png"] retain]; [image drawInRect:rect]; [image release]; } #pragma mark - #pragma mark UINavigationDelegate Methods - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{ // use the title of the passed in view controller NSString *title = [viewController title]; // create our own UILabel with custom color, text, etc UILabel *titleView = [[UILabel alloc] init]; [titleView setFont:[UIFont boldSystemFontOfSize:18]]; [titleView setTextColor:[UIColor blackColor]]; titleView.text = title; titleView.backgroundColor = [UIColor clearColor]; [titleView sizeToFit]; viewController.navigationItem.titleView = titleView; [titleView release]; viewController.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.1 green:0.2 blue:0.3 alpha:0.8]; } - (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{ } - (void)dealloc { [super dealloc]; } @end I know that I can use a category to change the background image, but i still want to be able to set the text color of the navigation bar title @implementation UINavigationBar (CustomImage) - (void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed: @"navigation_bar_bgd.png"]; [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)]; } @end any suggestions or other solutions? I basically want to create a light background and dark text like Flickr's app navigation bars

• jqGrid Coloring an entire line in Grid based upon a cells value

  - by Thomas

  Hi all, i know it's been asked before but i cant get it to run and i'm out of things to try. So i want to colorize a row in a Grid if its value is not 1 - i use a custom formatter for this. The formatter itself works, thats not the problem. I've tried multple ways I've found so far on the web - adding a class, directly adding css code, using setRowData, using setCell.... Here are my examples - none of them worked for me (linux, ff363) - any pointer would be gratly appreciated. 27.05.2010_00:00:00-27.05.2010_00:00:00 is my row id <style> .state_inactive { background-color: red !important; } .state_active { background-color: green !important; } </style> function format_state (cellvalue, options, rowObject) { var elem='#'+options.gid; if (cellvalue != 1) { jQuery('#list2').setRowData(options.rowID,'', {'background-color':'#FF6F6F'}); jQuery('#list2').setRowData('27.05.2010_00:00:00-27.05.2010_00:00:00', '',{'background-color':'#FF6F6F'}); for (var cnt=0;cnt<rowObject.length;cnt=cnt+1) { jQuery(elem).setCell(options.rowId,cnt,'','state_inactive',''); jQuery(elem).setCell('"'+options.rowId+'"',cnt,'','state_inactive'); jQuery(elem).setCell('"'+options.rowId+'"',cnt,'5', {'background-color':'#FF6F6F'},''); } } else { for (var cnt=0;cnt<rowObject.length;cnt=cnt+1) { jQuery(elem).setCell(options.rowId,cnt,'','state_active',''); } } <!-- dont modify, we simply added the class above--> return cellvalue; } Thanks, Thomas

• WPF unwanted grid splitter behaviour

  - by SaphuA

  Hello, I have a simple grid with 3 columns (one of which contains a grid splitter). When resizing the grid and the left column reaches its minimum width, instead of doing nothing it increases the width of the right column. Could anyone help me stop this? I can't set the max width of the right column, because the grid itself also resizes. Here's some sample code that shows the problem. While resizing, move the mouse over the red area: XAML: <Grid DockPanel.Dock="Top" Height="200"> <Grid.ColumnDefinitions> <ColumnDefinition MinWidth="200" Width="*" /> <ColumnDefinition Width="3" /> <ColumnDefinition MinWidth="120" Width="240" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="*" /> </Grid.RowDefinitions> <Rectangle Fill="Red" Grid.Row="0" Grid.Column="0" /> <DockPanel LastChildFill="True" Grid.Row="0" Grid.Column="2" > <Rectangle DockPanel.Dock="Right" Width="20" Fill="Blue" /> <Rectangle Fill="Green" /> </DockPanel> <GridSplitter Background="LightGray" Grid.Row="0" Grid.Column="1" Height="Auto" Width="Auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" /> </Grid>

• How do I make an ellipse blink?

  - by MedicineMan

  I am trying to make a custom control in WPF. I want it to simulate the behavior of a LED that can blink. There are three states to the control: On, Off, and Blinking. I know how to set On and Off through the code behind, but this WPF animation stuff is just driving me nuts!!!! I cannot get anything to animate whatsoever. The plan is to have a property called state. When the user sets the value to blinking, I want the control to alternate between green and grey. I'm assuming I need a dependency property here, but have no idea. I had more xaml before but just erased it all. it doesn't seem to do anything. I'd love to do this in the most best practice way possible, but at this point, I'll take anything. I'm half way to writing a thread that changes the color manually at this point. <UserControl x:Class="WpfAnimation.LED" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <Grid> <Ellipse x:Name="MyLight" Height="Auto" Width="Auto"/> </Grid> </UserControl>

• jqGrid with JSON data renders table as empty

  - by jgreep

  I'm trying to create a jqgrid, but the table is empty. The table renders, but the data doesn't show. The data I'm getting back from the php call is: { "page":"1", "total":1, "records":"10", "rows":[ {"id":"2:1","cell":["1","image","Chief Scout","Highest Award test","0"]}, {"id":"2:2","cell":["2","image","Link Badge","When you are invested as a Scout, you may be eligible to receive a Link Badge. (See page 45)","0"]}, {"id":"2:3","cell":["3","image","Pioneer Scout","Upon completion of requirements, the youth is invested as a Pioneer Scout","0"]}, {"id":"2:4","cell":["4","image","Voyageur Scout Award","Voyageur Scout Award is the right after Pioneer Scout.","0"]}, {"id":"2:5","cell":["5","image","Voyageur Citizenship","Learning about and caring for your community.","0"]}, {"id":"2:6","cell":["6","image","Fish and Wildlife","Demonstrate your knowledge and involvement in fish and wildlife management.","0"]}, {"id":"2:7","cell":["7","image","Photography","To recognize photography knowledge and skills","0"]}, {"id":"2:8","cell":["8","image","Recycling","Demonstrate your knowledge and involvement in Recycling","0"]}, {"id":"2:10","cell":["10","image","Voyageur Leadership ","Show leadership ability","0"]}, {"id":"2:11","cell":["11","image","World Conservation","World Conservation Badge","0"]} ]} The javascript configuration looks like so: $("#"+tableId).jqGrid ({ url:'getAwards.php?id='+classId, dataType : 'json', mtype:'POST', colNames:['Id','Badge','Name','Description',''], colModel : [ {name:'awardId', width:30, sortable:true, align:'center'}, {name:'badge', width:40, sortable:false, align:'center'}, {name:'name', width:180, sortable:true, align:'left'}, {name:'description', width:380, sortable:true, align:'left'}, {name:'selected', width:0, sortable:false, align:'center'} ], sortname: "awardId", sortorder: "asc", pager: $('#'+tableId+'_pager'), rowNum:15, rowList:[15,30,50], caption: 'Awards', viewrecords:true, imgpath: 'scripts/jqGrid/themes/green/images', jsonReader : { root: "rows", page: "page", total: "total", records: "records", repeatitems: true, cell: "cell", id: "id", userdata: "userdata", subgrid: {root:"rows", repeatitems: true, cell:"cell" } }, width: 700, height: 200 }); The HTML looks like: <table class="awardsList" id="awardsList2" class="scroll" name="awardsList" /> <div id="awardsList2_pager" class="scroll"></div> I'm not sure that I needed to define jsonReader, since I've tried to keep to the default. If the php code will help, I can post it too.

• IE8 CSS selector selects, but does not apply the style.

  - by Dan

  This is making me want to kill myself. I have some really simple CSS to style my input objects: input, button { border: 1px solid #c66600; background-color: white; color: #7d212f; font-family: "Eras Light ITC", Tahoma, sans; } But I don't like the ugly border it puts around radio buttons, so I use a selector to kill the border: input[type=radio] { border: none; } You can probably guess what browsers this works in and which ONE it does not work in. What's funny is when I press F12 to launch the excellent developer tools in IE8 it actually tells me that the style of the radio buttons has been overridden to 'none' just like I asked it to do, but the border remains on the radio button objects. I have tried a variety of semantic things, like setting the border width to 0px or the color to something insane like lime green, but it remains the originally assigned color that it got from the first style. And finally, I have tried only styling 'text' objects, in which case no style is applied to anything. Again, the browser claims to fulfill the CSS selection, but it visually does not happen. Thoughts? By the way, this is a DotNetNuke installation with generated code where I can't explicitly set the style of the radio buttons. Thanks, Dan

• Table element in CSS table-cell offsets other table-cell contents

  - by Matt Joiner

  The following table element in the "center" div causes the contents in the "left" divs to be offset by several pixels from the top (8 in my browser). Adding some text prior to the table removes this offset. Why? How do I stop this from happening without requiring a "dummy" line of text before my table? <html> <head> <style type="text/css"> #left { display: table-cell; background-color: blue; } #menu { background-color: green; } #center { background-color: red; display: table-cell; } </style> <body> <div id="left"> <div id="menu"> Menu 1<br> Menu 2<br> </div> </div> <div id="center"> <table><tr><td>This is the main contents.</tr></td></table> </div> <div id="left"> <div id="menu"> Menu 1<br> Menu 2<br> </div> </div> </body> </html>

• Problem using FtpWebRequest to append to file on a mainframe

  - by MusiGenesis

  I am using FtpWebRequest to append data to a mainframe file. Each record appended is 50 characters long, and I am adding them one record at a time. In our development environment, we do not have a mainframe, so my code was written and tested FTPing to a Windows-based FTP site instead of a mainframe. Initially, I was writing each record using a StreamWriter (using the stream from the FtpWebRequest) and writing each record using WriteLine (which automatically adds a CR/LF to the end). When we ran this for the first time in the test environment (in which we're writing to an actual MVS mainframe), our mainframe contact said the CR/LFs were not able to be read by his program (a green-screen mainframe program of some sort - he's sent me screen captures, which is all I know of it). I changed our code to use Write instead of WriteLine, but now my code executes successfully (i.e no thrown exceptions) when writing multiple records, but no matter how many records we append, he is only able to "see" the first record - according to his mainframe program, there is only one 50-character record in the file. I'm guessing that to fix this, I need to write some other line-delimiting character into the end of the stream (instead of CR/LF) that the mainframe will recognize as a record delimiter. Anybody know what this is, or how else I can fix this problem?

• Returning a list from a function in Python

  Hi, I'm creating a game for my sister, and I want a function to return a list variable, so I can pass it to another variable. The relevant code is as follows: def startNewGame(): while 1: #Introduction: print print """Hello, You will now be guided through the setup process. There are 7 steps to this.

• Tricky CSS Layout

  - by Meep3D

  So I am making a website with quite a problematic layout. There are four corner images TL, TR, BL and BR indicated by black blocks. The dark orange area is the main content (to a width of 960px), with the outside area denoted by the green arrow as the browser window. See diagram: The top image represents the site at its narrowest possible - it shouldn't be allowed to be narrower than this (960px) if it is larger than the defined area there should be no scrollbars. The bottom two images represent different widths of browser. The bottom left and right black blocks (images) should be at the bottom left and right of the screen at all times, unless the width falls to 960px, in which case the BL and BR images should poke into the main area slightly. If the site is shrunk to, say 200px, the BR image should not still be poking in the right corner. At this point I don't really care about it working exactly in IE6 (I can get it roughly working) but I can't even figure out how to do it fully without Javascript or extremely experimental CSS. Currently I am using absolutely positioned div's which sort of work, but don't work quite right. I think I'd be willing to accept a bit of JS if there is no other way but I'd rather not. Answer very appreciated!

• CSS background-images and Z-Index problem

  - by dscher

  Hope someone has an easy answer on this. I have a header image which is just a 75px high gradient with a fade on the bottom. I have it set as the background image on my header and I want to throw in a left-sidebar on my page. There is a transparency on the header image and when I have my sidebar I can't get it to sit behind the header. You can see in this screenshot: link text The green sidebar won't "sit" behind the header. I have the header z-index set to 99 and the sidebar to 1. I tried the reverse to make sure I didn't mix up my numbers but that didn't work. Both are absolutely positioned. I'm attaching their CSS selectors in the hopes someone has an easy answer. Am sure I'm missing something basic: div.header { z-index: 99; background: transparent; background-image: url(images/header_bg.png); position: absolute; height: 85px; width: 100%; font-family: Helvetica, Verdana, Arial, sans-serif; } div#leftsidebar { height: 400px; border-right-style: dashed; border-right-width: 1px; z-index: -1; margin-top: 75px; width: 200px; position: absolute; background-color: #66ff66; } Thanks.

• Xcode 3.2: Build & Analyze never finds any issues

  - by GamingHorror

  I've used the Clang Static Analyzer from the command line before. I wanted to try Xcode's built-in version via Build & Analyze. I never get any negative results even though i specially prepared my code with very obvious issues Clang was always able to point out: // over-releasing an object: [label release]; [label release]; // uninitialized vars, allocating but not freeing an object NSString* str; int number; CCLabel* newLabel = [[CCLabel alloc] initWithString:str fontName:str fontSize:number]; [newLabel setPosition:CGPointZero]; The result is always the same: a green checkbox, no issues. I read that C++ code can cause issues. I'm running this with cocos2d that includes box2d. Could this be a cause? Did anyone get results from Build & Analyze with the cocos2d engine? What else could it be? I also tried enabling the Static Analyzer Build Settings and then Build but the result was the same. I have restarted Xcode, cleaned all targets and emptied Xcode caches to no avail.

• matplotlib: how to refresh figure.canvas

  - by Alex

  Hello, I can't understand how to refresh FigureCanvasWxAgg instance. Here is the example: import wx import matplotlib from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas from matplotlib.figure import Figure class MainFrame(wx.Frame): def __init__(self): wx.Frame.__init__(self, None, wx.NewId(), "Main") self.sizer = wx.BoxSizer(wx.VERTICAL) self.figure = Figure(figsize=(1,2)) self.axe = self.figure.add_subplot(111) self.figurecanvas = FigureCanvas(self, -1, self.figure) self.buttonPlot = wx.Button(self, wx.NewId(), "Plot") self.buttonClear = wx.Button(self, wx.NewId(), "Clear") self.sizer.Add(self.figurecanvas, proportion=1, border=5, flag=wx.ALL | wx.EXPAND) self.sizer.Add(self.buttonPlot, proportion=0, border=2, flag=wx.ALL) self.sizer.Add(self.buttonClear, proportion=0, border=2, flag=wx.ALL) self.SetSizer(self.sizer) self.figurecanvas.Bind(wx.EVT_LEFT_DCLICK, self.on_dclick) self.buttonPlot.Bind(wx.EVT_BUTTON, self.on_button_plot) self.buttonClear.Bind(wx.EVT_BUTTON, self.on_button_clear) self.subframe_opened = False def on_dclick(self, evt): self.subframe = SubFrame(self, self.figure) self.subframe.Show(True) self.subframe_opened = True def on_button_plot(self, evt): self.axe.plot(range(10), color='green') self.figurecanvas.draw() def on_button_clear(self, evt): if self.subframe_opened: self.subframe.Close() self.figure.set_canvas(self.figurecanvas) self.axe.clear() self.figurecanvas.draw() class SubFrame(wx.Frame): def __init__(self, parent, figure): wx.Frame.__init__(self, parent, wx.NewId(), "Sub") self.sizer = wx.BoxSizer(wx.VERTICAL) self.figurecanvas = FigureCanvas(self, -1, figure) self.sizer.Add(self.figurecanvas, proportion=1, border=5, flag=wx.ALL | wx.EXPAND) self.SetSizer(self.sizer) self.Bind(wx.EVT_CLOSE, self.on_close) def on_close(self, evt): self.GetParent().subframe_opened = False evt.Skip() class MyApp(wx.App): def OnInit(self): frame = MainFrame() frame.Show(True) self.SetTopWindow(frame) return True app = MyApp(0) app.MainLoop() I'm interested in the following sequence of operations: run a script resize the main frame press Plot button double click on plot press Clear button Now I get a mess on main frame plot. If I resize the frame it redraws properly. My question is what should I add to my code to do that without resizing? Thanks in advance.

• Is it possible to seletively color a wrapping TextBlock in Silverlight/WPF

  - by joemoe

  For instance, if I have a TextBlock: "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum." I want the first 10% of this TextBlock, such that the font color should be red, and the rest should be green. This perhaps means it would color the "Lorem ipsum dolor sit amet, consectetur adipisici", and part of the "n". Basically pixel-wise font coloring instead of character-wise. Another important behavior is that the percentage respects the wrapping, in that if 50% of the TextBlock contents is colored, it should mean 50% of the text in reading order is colored, and not the first half of the block. For example, this is a similar question (with correct answers), but regarding Label/TextBlocks with no wrapping: http://stackoverflow.com/questions/2394421/is-it-possible-to-seletively-color-a-label-in-silverlight

• make emacs in a terminal use dark colors and not light font-lock colors

  - by vy32

  I am using emacs on MacOS 10.6 with Terminal. I have a white background. It's very hard to read quoted C++ strings. They are coming up in pale green. Keywords are in turquoise. After searching through the source I cam across cpp.el and have determined that I am using the cpp-face-light-name-list instead of cpp-face-dark-name-list. Apparently this function is supposed to chose the correct list based on the background color: (defcustom cpp-face-default-list nil "Alist of faces you can choose from for cpp conditionals. Each element has the form (STRING . FACE), where STRING serves as a name (for `cpp-highlight-buffer' only) and FACE is either a face (a symbol) or a cons cell (background-color . COLOR)." :type '(repeat (cons string (choice face (cons (const background-color) string)))) :group 'cpp) But it doesn't seem to be working. What should I put in my .emacs file so that I get the cpp-face-dark-list instead of cpp-face-light-list? Thanks!

• App.config for SpecFlow not recognized by NUnit GUI runner

  - by INTPnerd

  How do I get my App.config file to be recognized/used by the NUnit GUI runner? I have tried placing it in the top folder of my project and in the same folder as my feature files. Here are the contents of my App.config file: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="specFlow" type="TechTalk.SpecFlow.Configuration.ConfigurationSectionHandler, TechTalk.SpecFlow"/> </configSections> <specFlow> <runtime detectAmbiguousMatches="true" stopAtFirstError="false" missingOrPendingStepsOutcome="Error" /> </specFlow> </configuration> Specifically I am trying to tell NUnit to have a fail result when there is a missing or pending step which is why I am specifying "Error" for this. This actually works correctly when I use TestDriven.net but not when I use the NUnit GUI runner. The GUI always shows a green bar and displays the test as Inconclusive instead of Error or Failed

• Access <body> tag properties from form found in mediaboxAdvanced lightbox.

  - by Christopher Richa

  I am building my portfolio website simply using HTML, Flash, and the Mootools Javascript framework. I have decided to implement a theme changing feature using Javascript and cookies. When the user clicks on the "Change Theme" link, a mediaboxAdvanced lightbox appears, containing a real-time form which allows you to change the theme on the portfolio. Here's the code for the form: <div id="mb_inline" style="display: none; margin:15px;"> <h3>Change Your Theme</h3> <form> <fieldset> <select id="background_color" name="background_color"> <option value="#dcf589">Original</option> <option value="#000FFF">Blue</option> <option value="#00FF00">Green</option> </select> </fieldset> </form> </div> I know, there is no submit button, but as soon as something is changed in that form, the following Mootools code happens: var themeChanger = new Class( { pageBody : null, themeOptions : null, initialize: function() { this.pageBody = $(document.body); this.themeOptions = $('background_color'); this.themeOptions.addEvent('change', this.change_theme.bindWithEvent(this)); }, change_theme: function(event) { alert("Hello"); } }); window.addEvent('domready', function() { var themeChanger_class = new themeChanger(); }); Now this is only a test function, which should be triggered when the dropdown menu changes. However, it seems that none of it works when the form is in the lightbox! Now if I decide to run the form outside of the lightbox, then it works great! Am I missing something? If you need more examples, I will fill in on demand. Thank you all in advance. -Christopher

• Raytracing (LoS) on 3D hex-like tile maps

  - by herenvardo

  Greetings, I'm working on a game project that uses a 3D variant of hexagonal tile maps. Tiles are actually cubes, not hexes, but are laid out just like hexes (because a square can be turned to a cube to extrapolate from 2D to 3D, but there is no 3D version of a hex). Rather than a verbose description, here goes an example of a 4x4x4 map: (I have highlighted an arbitrary tile (green) and its adjacent tiles (yellow) to help describe how the whole thing is supposed to work; but the adjacency functions are not the issue, that's already solved.) I have a struct type to represent tiles, and maps are represented as a 3D array of tiles (wrapped in a Map class to add some utility methods, but that's not very relevant). Each tile is supposed to represent a perfectly cubic space, and they are all exactly the same size. Also, the offset between adjacent "rows" is exactly half the size of a tile. That's enough context; my question is: Given the coordinates of two points A and B, how can I generate a list of the tiles (or, rather, their coordinates) that a straight line between A and B would cross? That would later be used for a variety of purposes, such as determining Line-of-sight, charge path legality, and so on. BTW, this may be useful: my maps use the (0,0,0) as a reference position. The 'jagging' of the map can be defined as offsetting each tile ((y+z) mod 2) * tileSize/2.0 to the right from the position it'd have on a "sane" cartesian system. For the non-jagged rows, that yields 0; for rows where (y+z) mod 2 is 1, it yields 0.5 tiles. I'm working on C#4 targeting the .Net Framework 4.0; but I don't really need specific code, just the algorithm to solve the weird geometric/mathematical problem. I have been trying for several days to solve this at no avail; and trying to draw the whole thing on paper to "visualize" it didn't help either :( . Thanks in advance for any answer

• iPhone SDK - UITabBarConroller and custom design

  - by Cheryl

  Hi I am having a problem with my tab bars at the bottom of the screen. The designer has decided it should be one colour (not black) when inactive and another colour when active. I have worked out how to replace the main colour of the tabbar by subclassing UITabBarController and doing this:- - (void)viewDidLoad { [super viewDidLoad]; CGRect frame = CGRectMake(0.0, 0, self.view.bounds.size.width, self.view.bounds.size.height); UIView *v = [[UIView alloc] initWithFrame:frame]; //get percentage values from digitalcolour meter and enter as decimals v.backgroundColor = [UIColor colorWithRed:.0 green:.706 blue:.863 alpha:1]; [tabBar1 insertSubview:v atIndex:0]; [v release]; } I just can't see how to make the active tabbar be a separate colour when it is selected. I have tried subclassing UITabBarItem but there doesn't seem to be any property for me to set to change the background colour of the tab. They also want to have the icons on the tab bar not be blue and grey and I can't figure out how to do that. In the ViewController for one tab bar item I have put this into viewdidload:- myTabBarItem *tabItem = [[myTabBarItem alloc] initWithTitle:@"listOOO" image:[UIImage imageNamed:@"starcopy.png"] tag:1]; tabItem.customHighlightedImage=[UIImage imageNamed:@"starcopy.png"]; self.tabBarItem=tabItem; [tabItem release]; tabItem=nil; and in my subclass of UITabBarItem I have put this:- -(UIImage *) selectedImage{ return self.customHighlightedImage; } Only I don't see the icon at all. If I put this into the viewDidLoad of my subclass of UITabBarController:- for (UITabBarItem *item in tabBar1.items){ item.image = [UIImage imageNamed:@"starcopy.png"]; } Then all my tab bars have the icon but they are blue (and grey when inactive) how would I get them not to become blue but stay their original colour? If you have any light on this problem please help as I have been banking my head on the wall for 2 days now and it's getting me down. Thanks in advance Cheryl
