  • Problem of Sprites and labels are displayed by white boxes.

    - by srikanth rongali
    I am writing a game in cocos2d. I am using a function restartDirector in AppDelegate class. -(void)restartDirector{ [[CCDirector sharedDirector] end]; [[CCDirector sharedDirector] release]; if( ! [CCDirector setDirectorType:CCDirectorTypeDisplayLink] ) [CCDirector setDirectorType:CCDirectorTypeDefault]; [[CCDirector sharedDirector] setPixelFormat:kPixelFormatRGBA8888]; [CCTexture2D setDefaultAlphaPixelFormat:kTexture2DPixelFormat_RGBA8888]; [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] setDisplayFPS:YES]; [[CCDirector sharedDirector] setDeviceOrientation:CCDeviceOrientationLandscapeLeft]; [[CCDirector sharedDirector] attachInView:window]; } This function I called in one of the game Scene . -(void)PracticeMethod:(id)sender { [MY_DELEGATE restartDirector]; CCScene *endPageScene = [CCScene node]; CCLayer *endPageLayer = [DummyScene node]; [endPageScene addChild:endPageLayer]; [[CCDirector sharedDirector] runWithScene:endPageScene]; // [[CCDirector sharedDirector] replaceScene:endPageScene]; } When used the replaceScene, there is no problem in game but the memory of abject allocation is high(I checked in leaks tool). So I used runWithScene. But , while using these when the scene DummyScene is loaded the sprites, labels in it are displayed by white boxes. I cannot see the sprites and labels. If I am using replaceScene everything thing is working fine but the memory allocation is high. this is my problem. Thank you.

  • jQuery and Ajax

    - by Banderdash
    Can anyone help with a jQuery snippet that would use Ajax to pull an XML file in on page load? Have really clunky way of doing it without jQuery here: <script type="text/javascript"> function loadXMLDoc() { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { xmlDoc=xmlhttp.responseXML; var txt=""; x=xmlDoc.getElementsByTagName("title"); for (i=0;i<x.length;i++) { txt=txt + x[i].childNodes[0].nodeValue + "<br />"; } document.getElementById("checkedIn").innerHTML=txt; } } xmlhttp.open("GET","ajax-response-data.xml",true); xmlhttp.send(); } </script> Ideally rather the having a click generate the list it would do so on page load, showing the fields from the XML (title, author, and whether it is checked in or not i.e. <book id="#" checked-in="0">) Would hug you for a solution.

  • Trying to override onbeforeunload in first step of form wizard

    - by Dirty Bird Design
    This pertains to a form wizard with 5 steps, I don't want the user to hit back and lose form data in any step 2-4. I have added a flag for the submit function and need to add this one for the first step. If they get there by accident and try and leave I dont want the cofirm dialog popping up. <script type="text/javascript"> $(document).ready(function(){ var action_is_post = false; $("form").submit(function () { action_is_post = true; }); //this is the trouble spot. on the first step the "navigation" of the form has a class of current (on step one = current) $(this).ready(function () { if ($("#stepDesc0").is(".current")) { action_is_post = true; } ); window.onbeforeunload = confirmExit; function confirmExit() { if (!action_is_post) return 'Using the browsers back, refresh or close button will cause you to lose all form data. Please use the Next and Back buttons on the form.'; } }); </script>

  • IE "Microsoft JScript runtime error: Object expected"

    - by Stephen Borg
    Hi there, I have problems with regards to javascript only when using IE. The error I am getting is "Microsoft JScript runtime error: Object expected" and I have no idea why. It is then jumping into the JQuery 1.4.2 file, without giving me a proper error message. All I am doing is simply reading on page load the raw URL, and getting a query string named Search. Using that in an AJAX call to return products and put then into a DIV. No biggies, but somehow IE is managing to blow my page up :-( Any ideas? Code as follows : <script type="text/javascript"> $(document).ready(function (e) { $('.boxLoader').show(); function getParameterByName(name) { name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); var regexS = "[\\?&]" + name + "=([^&#]*)"; var regex = new RegExp(regexS); var results = regex.exec(window.location.href); if (results == null) return ""; else return decodeURIComponent(results[1].replace(/\+/g, " ")); } var Search; Search = getParameterByName("search"); $('#searchCriteria').text(Search); $.get("/Handlers/processProducts.aspx", { SearchCriteria: Search }, function (data) { $('#innercontent').html(data); $('#innercontent').fadeIn(200); $('.boxLoader').fadeOut(200); }); $('#searchBox').live("click", function () { $.get("/Handlers/processProducts.aspx", { SearchCriteria: $('#searchCriteria').val() }, function (data) { $('#innercontent').html(data); $('#innercontent').fadeIn(200); $('.boxLoader').fadeOut(200); }); }); }); </script>

  • AddEvenLister fires off immediately after being attached

    - by Diego
    I want to know how to correctly add an Event Listener like onClick to a dynamic div. Here’s my snippet: var $menu = new Array(2); createDiv('yes'); function createDiv(title) { var $class = 'menuLink'; var $title = 'title'; for(var i=0; i<$menu.length;i++) { $title = 'title'; var newdiv = document.createElement('div'); newdiv.setAttribute('class', $class); newdiv.setAttribute('id', 'item'+i); newdiv.addEventListener('onclick', clickHandle(newdiv.id),false); if (title) { newdiv.innerHTML = $title; } else { newdiv.innerHTML = "No Title"; } document.getElementById('menu').appendChild(newdiv); showMenu(); } } function clickHandle(e) { if(e == 'item0') { alert('Link is' + ' ' + e); }else{ alert('Another Link'); } } Here's my problem, the snippet works fine, It creates my divs, adds id's values and all, but the event fires off as soon as the event is attached, so while the for loop is creating the divs the alert window says: Link is item0, and immediately after this it says: Another Link. Am I misunderstanding this? (I used this method zillions of times in AS3 with the expected result, just attached a function waiting for a click). What I want is that my Divs wait for the user to click on them, not to fire off immediately after of being attached. Thanks for any hint on this one. Greetings. Ps. IE doesn't support addEventListener, but I want to resolve this before cross to the IE sea of madness, but I will appreciate the IE approach as well. - I tried "onclick" and just 'click' into the addEventListener line, both with the same result described above.

  • JSF: Showing/Calling a dialog programatically

    - by Sway
    has anybody an idea to show/call a dialog programatically and add this to stage(actual browser window) ?! I am running in circles and cannot find a solution :/ More background what I want to do: I want to trigger a database update every 2 hours. This I have done with a TimerTask... This works fine for me, the Timertask gets all the data I want from the database... Before this TimerTask is triggered I want to "lock" the screen for some seconds that no user(session scoped) can access the database(this I also know how this will work) ... My problem is that I don't know/ cannot find a way/ i am to stupid to call a dialog programatically ... Any tips, hints would be very cool :) Thanks a lot ! UPDATE: I want to set this primefaces dialog: Dialog dialog = new Dialog(); dialog.setAppendToBody(true); dialog.setModal(true); dialog.setVisible(true); dialog.setWidgetVar("generatedDialog"); dialog.setId("fancyDialog"); dialog.setClosable(false); dialog.setHeader("Getting latest information from the database"); dialog.setDynamic(true); dialog.setResizable(false); dialog.setDraggable(false); How can I do that ? :/ How do I display it to my browser ? :o Regards

  • ScaleTransform transforms non-linearly

    - by Chris
    I am using scale transform to allow a user to resize a control. What happens though is that when you start to move the mouse the control jumps to a new size, and then scales oddly. The further you move your mouse from the starting location the larger the increase in size becomes. I expect its the way I calculate the scale to be applied. Here is the code: private void ResizeGrip_MouseDown(object sender, MouseButtonEventArgs e) { ResizeHandle.CaptureMouse(); //Get the initial coordinate cursor location on the window initBtmX = e.GetPosition(this).X; bottomResize = true; } private void ResizeGrip_MouseUp(object sender, MouseButtonEventArgs e) { bottomResize = false; ResizeHandle.ReleaseMouseCapture(); } private void ResizeGrip_MouseMove(object sender, MouseEventArgs e) { if( bottomResize == true) { //Get the new Y coordinate cursor location double newBtmX = e.GetPosition(this).X; //Get the smallest change between the initial and new cursor location double diffX = initBtmX - newBtmX; // Let our rectangle capture the mouse ResizeHandle.CaptureMouse(); double newWidth = e.GetPosition(this).X - diffX; double scaler = newWidth / ResizeContainer.ActualWidth; Console.WriteLine("newWidth: {0}, scalar: {1}", newWidth, scaler); if (scaler < 0.75 || scaler > 3) return; ScaleTransform scale = new ScaleTransform(scaler, scaler); ResizeContainer.LayoutTransform = scale; } }

  • Sort command not working as expected

    - by user964689
    If anybody can help me to write a loop to iterate over files in a folder it would save me a huge amount of time. I think it must be quite a simple solution ,but I currently don't know how to nest a loop within a loop. So far I have this script: cd /folderlocation/ for i in `</textfile_containing_lines_to_iterate_through` do #size=`echo $i | perl -nE '/:([\d-]+)/ && say abs(eval $1)'` #echo "$size" zcat dataset | head -n 18 > temp"$i".vcf tabix dataset $i >> temp"$i".vcf vcftools --window-pi 1000000 --vcf temp10individuals"$i".vcf >> run_summary.txt cat out.windowed.pi >> outputfile_2 #rm temp* done grep -v "PI" outputfile_2 > outputfile rm outputfile_2 I need to expand this so that the script will run multiple times, through all of the 'textfiles_containing_lines_to_iterate_through'. Currently I change the name of the textfile manually each time and re-run the script. So I'd need a loop that does this for file in folder, and also that uses the name of the file as part of the outputfile name so that I can match an output file to an inputfile. Any help would be really useful and greatly appreciated! Many thanks in advance.

  • How to maintain long-lived python projects w.r.t. dependencies and python versions ?

    - by Gyom
    short version: how can I get rid of the multiple-versions-of-python nightmare ? long version: over the years, I've used several versions of python, and what is worse, several extensions to python (e.g. pygame, pylab, wxPython...). Each time it was on a different setup, with different OSes, sometimes different architectures (like my old PowerPC mac). Nowadays I'm using a mac (OSX 10.6 on x86-64) and it's a dependency nightmare each time I want to revive script older than a few months. Python itself already comes in three different flavours in /usr/bin (2.5, 2.6, 3.1), but I had to install 2.4 from macports for pygame, something else (cannot remember what) forced me to install all three others from macports as well, so at the end of the day I'm the happy owner of seven (!) instances of python on my system. But that's not the problem, the problem is, none of them has the right (i.e. same set of) libraries installed, some of them are 32bits, some 64bits, and now I'm pretty much lost. For example right now I'm trying to run a three-year-old script (not written by me) which used to use matplotlib/numpy to draw a real-time plot within a rectangle of a wxwidgets window. But I'm failing miserably: py26-wxpython from macports won't install, stock python has wxwidgets included but also has some conflict between 32 bits and 64 bits, and it doesn't have numpy... what a mess ! Obviously, I'm doing things the wrong way. How do you usally cope with all that chaos ?

  • Event not triggering

    - by the Hampster
    I have no idea where to start on this one. I have a that does not appear until a button is clicked. This function call works: onclick="highlight('mod_sup_div', true);" function highlight(aDiv,show) { if (show) { Effect.Appear('Overlay',{duration: 0.5, to: .80}); Effect.Appear(aDiv,{duration: 0.5}) } else { Effect.Fade('Overlay',{duration: 0.5, to: .80}); Effect.Fade(aDiv,{duration: 0.5}) } } In the <div> I have a button to close the window. <p class="closer"><span onclick="highlight('mod_sup_div',false)">X</span></p> This does not work. The function is not even called, as I made a alert() the first line of the function at it does nothing. What is odd, is that onclick="Effect.Fade(aDiv,{duration: 0.5})" does work. Other simple javascript functions in the onclick="" work, except for the function call. Any help as to why this is happening would be very appreciated. Thanks, Dave

  • Issues with simulating cell selection in Excel using PostMessage

    - by DD
    Hi all, So far I've tried drag/drop motion in many applications including Visualization software (moving time slider left/right), Photoshop-Paint (drawing) etc. I need some more testing before I make sure that my system works and it failed in Excel. I'm using the code below to send the input: m.x = 215; m.y = 200 + 36 + 9 * ( currentTime - 1 ); childH = findChild( w->getHandle(), m ); PostMessage( childH, WM_MOUSEMOVE, 0, MAKELPARAM( m.x, m.y ) ); PostMessage( childH, WM_LBUTTONDOWN, MK_LBUTTON, MAKELPARAM( m.x, m.y ) ); m.x = 215; m.y = 200 + 36 + 9 * ( currentTime ); childH = findChild( w->getHandle(), m ); PostMessage( childH, WM_MOUSEMOVE, MK_LBUTTON, MAKELPARAM( m.x, m.y ) ); PostMessage( childH, WM_LBUTTONUP, 0, MAKELPARAM( m.x, m.y ) ); I can click anywhere in Excel and select the cell, or activate buttons/menus anything. I can even drag a plot around (with the code above) but it doesn't work for clicking and dragging the mouse to select multiple cells. It just doesn't do anything. I can't use SendInput because the window doesn't have the focus and is in background. Thanks!

  • Javascript onclick() event bubbling - working or not?

    - by user1071914
    I have a table in which the table row tag is decorated with an onclick() handler. If the row is clicked anywhere, it will load another page. In one of the elements on the row, is an anchor tag which also leads to another page. The desired behavior is that if they click on the link, "delete.html" is loaded. If they click anywhere else in the row, "edit.html" is loaded. The problem is that sometimes (according to users) both the link and the onclick() are fired at once, leading to a problem in the back end code. They swear they are not double-clicking. I don't know enough about Javascript event bubbling, handling and whatever to even know where to start with this bizarre problem, so I'm asking for help. Here's a fragment of the rendered page, showing the row with the embedded link and associated script tag. Any suggestions are welcomed: <tr id="tableRow_3339_0" class="odd"> <td class="l"></td> <td>PENDING</td> <td>Yabba Dabba Doo</td> <td>Fred Flintstone</td> <td> <a href="/delete.html?requestId=3339"> <div class="deleteButtonIcon"></div> </a> </td> <td class="r"></td> </tr> <script type="text/javascript">document.getElementById("tableRow_3339_0").onclick = function(event) { window.location = '//edit.html?requestId=3339'; };</script>

  • How to make flash movie to scale proportunatly to div width?

    - by user73119
    I have put together an example page detailing my problem My website is going to have a main wrapper that is set to a max-width property for compatible browsers. It will stretch to 940px across at max. When scaled down I would like the swf to scale proportionately with it. Like an image with width percent applied. The flash movie has the dimensions of 940 × 360 pixels. I can't seem to figure out the correct attributes to add to the embed tag to get it to do this. I am currently using jquery flash embed, but am open to other options, though this is my ideal. In the example I have set the flash background to black. When resize the browser window the flash movie doesn't scale proportionately to the div, only the photo does, leaving a blank canvas (black), while the div height stays the same. I can't add a height value in the CSS. How do I make this scale correctly? Adding a noscale param only crops the image. The swf's height doesn't scale also. All of my code can be viewed in the linked examples source.

  • Cannot install windows service

    - by Matthew Dalton
    I have created a very simple window service using visual studio 2010 and .Net 4.0. This service has no functionality added from the default windows service project, other than an installer has been added. If i run installutil.exe appName.exe on my dev box or other windows 2008 R2 machines in our domain the windows service installs without issue. When i try to do this same thing on our customer site, it fails to install with the following error. Microsoft (R) .NET Framework Installation utility Version 4.0.30319.1 Copyright (c) Microsoft Corporation. All rights reserved. Exception occurred while initializing the installation: System.IO.FileLoadException: Could not load file or assembly 'file:///C:\TestService\WindowsService1.exe' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515). This solution has only 1 project and no dependencies added. I have tried it on multiple machines in our environment and two in our customers. The machines are all windows 2008 R2, both fresh installs. One machine has just .net 2.0 and .net 4.0. The other .net 2, 3, 3.5 and 4. I am a local admin on each of the machines. I have also tried the 64bit installer but get the following error, so i think the 32 bit one is the one to use. System.BadImageFormatException Any guidance would be appreciated. Thanks.

  • How to set margin for inner controls of WrapPanel

    - by Andrey Tagaew
    Hi Guys! I'm new in WPF and have a question. Here is an example that I'm using: <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <StackPanel> <WrapPanel Orientation="Horizontal" > <Button Content="test1" Margin="10,0" Padding="10,10" /> <Button Content="test2" Margin="10,0" Padding="10,10" /> <Button Content="test3" Margin="10,0" Padding="10,10" /> <Button Content="test4" Margin="10,0" Padding="10,10" /> <Button Content="test5" Margin="10,0" Padding="10,10" /> </WrapPanel> </StackPanel> As you can see, my wrap panel has several buttons. Each button has the same margin and padding. The question is, is there a way of setting margin and padding for wrap panel, so each element inside the wrap panel may use it values? This make the code shorter and let me specify Margin and Padding only one time instead of setting it for each control in the panel. Thank you!

  • Why is alert not run even though $.getJSON runs fine? (Callback not executed, even though the reques

    - by Emre Sevinç
    I have a snippet of code such as: $.getJSON("http://mysite.org/polls/saveLanguageTest?url=" + escape(window.location.href) + "&callback=?", function (data) { var serverResponse = data.result; console.log(serverResponse); alert(serverResponse); }); It works fine in the sense that it makes a cross-domain request to my server and the server saves the data as I expect. Unfortunately, even though the server saves data and sends back a response I just can't get any alert or the console.log run. Why may be that? The server side code is (if that is relevant): def saveLanguageTest(request): callback = request.GET.get('callback', '') person = Person(firstName = 'Anonymous', ipAddress = request.META['REMOTE_ADDR']) person.save() webPage = WebPage(url = request.GET.get('url')) webPage.save() langTest = LanguageTest(type = 'prepositionTest') langTest.person = person langTest.webPage = webPage langTest.save() req ['result'] = 'Your test is saved.' response = json.dumps(req) response = callback + '(' + response + ');' return HttpResponse(response, mimetype = "application/json") What am I missing? (I tried the same code both within my web pages and inside the Firebug and I always have the problem stated above.)

  • Pop-up and font colour based problems in a form which is designed in Share Point.

    - by ephieste
    I am designing a system in Share Point via Share Point Designer. We have a form in my Share Point site. Users have to fill some fields in the form and send it to the approval committee. We cannot upload anything to the servers. The design is site based. Our problems are: 1- I want to add small (?) icons for the descriptions of that field. When the user click on the (?) icon for "brief description" field a pop-up or another window will be opened and perhaps it will say: Enter a description of the requested thing. Be as specific as possible. 2- I want to change the font colors of the fields in the form. The share point brings them black as default. Such as I want to see the "Brief description:" and "Status:" as purple instead of black. Brief description: ..... Status: ..... 3- I want to add an agreement pop-up to the new form which will be open just after clicking "send" button in the form. The pop up will say: "Are you sure that you read the procedure" . The user has to click "Yes" to continue sending the form. Otherwise It will return to previous screen again. I would be glad if you kindly help me.

  • WPF data-bound ComboBox only shows first item of ItemsSource list

    - by Mark
    Hi all, I'm sure I'm doing something stupid but for the life of me I can't think of right now. I have a ComboBox that is data-bound to a list of Layout objects. The list is initially empty but things are added over time. When the list is updated by the model the first time, this update reflects properly in the ComboBox. However, subsequent updates never show up in the ComboBox even though I can see that the list itself contains these items. Since the first update works, I know the data-binding is OK - so what am I doing wrong here? Here's the XAML (abridged): <Grid HorizontalAlignment="Stretch"> <ComboBox ItemsSource="{Binding Path=SavedLayouts, diagnostics:PresentationTraceSources.TraceLevel=High}" DisplayMemberPath="Name" SelectedValuePath="Name" SelectedItem="{Binding LoadLayout}" Height="25" Grid.Row="1" Grid.Column="0"></ComboBox> </Grid> And the related part of the model: public IList<Layout> SavedLayouts { get { return _layouts; } } public Layout SaveLayout( String data_ ) { Layout theLayout = new Layout( SaveLayoutName ); _layouts.Add( theLayout ); try { return theLayout; } finally { PropertyChangedEventHandler handler = PropertyChanged; if( handler != null ) { handler( this, new PropertyChangedEventArgs( "SavedLayouts" ) ); } } } And finally, the layout class (abridged): public class Layout { public String Name { get; private set; } } In the output window, I can see the update occurring: System.Windows.Data Warning: 91 : BindingExpression (hash=64564967): Got PropertyChanged event from TickerzModel (hash=43624632) System.Windows.Data Warning: 97 : BindingExpression (hash=64564967): GetValue at level 0 from TickerzModel (hash=43624632) using RuntimePropertyInfo(SavedLayouts): List`1 (hash=16951421 Count=11) System.Windows.Data Warning: 76 : BindingExpression (hash=64564967): TransferValue - got raw value List`1 (hash=16951421 Count=11) System.Windows.Data Warning: 85 : BindingExpression (hash=64564967): TransferValue - using final value List`1 (hash=16951421 Count=11) But I get do not get this 11th item in the ComboBox. Any ideas?

  • removing mouse events/controls from swing components with glasspane

    - by Deger
    Hi all, I have a client-server application and i am using swing in the client side. My swing client has one main window (jframe) and lots of panels, toolbars and menubar in it. I want to remove all client action/mouse events (or simply grab and do nothing) while client is waiting response from server by means of glasssPane. Here is the code i wrote: private final static MouseAdapter mouseAdapter = new MouseAdapter() { public void mouseClicked(MouseEvent e) { System.out.println("MouseClicked..!"); } }; private static Cursor WAIT_CURSOR = Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR); private static Cursor DEFAULT_CURSOR = Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR); and public static void startWaitCursor(JComponent comp) { MainWindow root = ((MainWindow) comp.getTopLevelAncestor()); root.getGlassPane().setCursor(WAIT_CURSOR); root.getGlassPane().addMouseListener(mouseAdapter); root.getGlassPane().setVisible(true); } public static void stopWaitCursor(JComponent comp) { MainWindow root = ((MainWindow) comp.getTopLevelAncestor()); root.getGlassPane().setCursor(DEFAULT_CURSOR); root.getGlassPane().setVisible(false); } but i am not able to manage the grab mouse events. Changing cursors at the glassPane is working fine but either i am not able to add mouseAdapter or am not able to make glasssPane become to the top level component. Any idea? Thanks.

    I use a dynamic table: <html> <body> <button id="button">Build table</button> <div id="container"> <script type="text/javascript"> window.onload=function(){ var table = null; var row = "<tr><td>111111111111111111111111111111111111111111111111111111</td>" + "<td>222222222222222222222222222222222222222222222222222222</td>" + "<td>333333333333333333333333333333333333333333333333333333</td></tr>"; var data = null; for (var i = 0; i < 2000; i++){ data += row; } var obj = document.getElementById("button"); obj.onclick=function buildTable(){ document.getElementById("container").innerHTML = "<div><table><tbody>" + data + "</tbody></table></div>"; }; }; </script> </body> </html> Using chromes task manager, each time new data is loaded the memory usage increases considerably and doesn't go down, so after some time the app consumes a lot of memory and requires the browser to be closed. Is there any change in the code I can use to solve this or is it a browser side problem?

  • ncurses - resizing glitch

    - by ryyst
    I'm writing an ncurses program and am trying to make it respond correctly to terminal resizing. While I can read the terminal dimensions correctly in my program, ncurses doesn't seem to deal with new dimensions correctly. Here's a (somewhat lengthy) sample program: #include <ncurses.h> #include <string.h> #include <signal.h> #include <sys/ioctl.h> void handle_winch(int sig){ struct winsize w; ioctl(0, TIOCGWINSZ, &w); COLS = w.ws_col; LINES = w.ws_row; wresize(stdscr, LINES, COLS); clear(); mvprintw(0, 0, "COLS = %d, LINES = %d", COLS, LINES); for (int i = 0; i < COLS; i++) mvaddch(1, i, '*'); refresh(); } int main(int argc, char *argv[]){ initscr(); struct sigaction sa; memset(&sa, 0, sizeof(struct sigaction)); sa.sa_handler = handle_winch; sigaction(SIGWINCH, &sa, NULL); while(getch() != 27) {} endwin(); return 0; } If you run it, you can see that the terminal dimensions are correctly retrieved. But the second line, which is supposed to draw *-characters across the screen, doesn't work. Try resizing the window horizontally to make it larger, the line of *s will not get larger. What's the problem here? I'm aware that one can temporarily leave curses mode, but I'd prefer a cleaner solution. Thanks!

  • returning opengl display callback in D

    - by Max
    I've written a simple hello world opengl program in D, using the converted gl headers here. My code so far: import std.string; import c.gl.glut; Display_callback display() { return Display_callback // line 7 { return; // just display a blank window }; } // line 10 void main(string[] args) { glutInit(args.length, args); glutInitDisplayMode(GLUT_RGB | GLUT_DEPTH | GLUT_DOUBLE); glutInitWindowSize(800,600); glutCreateWindow("Hello World"); glutDisplayFunc(display); glutMainLoop(); } My problem is with the display() function. glutDisplayFunc() expects a function that returns a Display_callback, which is typedef'd as typedef GLvoid function() Display_callback;. When I try to compile, dmd says line 7: found '{' when expecting ';' following return statement line 10: unrecognized declaration How do I properly return the Display_callback here? Also, how do I change D strings and string literals into char*? My calls to glutInit and glutCreateWindow don't like the D strings they're getting. Thanks for your help.

  • Multiple usage of MenuItems declared once (WPF)

    - by Alex Kofman
    Is it possible in WPF to define some menu structure and than use it in multiple contexts? For example I'd like to use a set of menu items from resources in ContextMenu, Window's menu and ToolBar (ToolBar with icons only, without headers). So items order, commands, icons, separators must be defined just once. I look for something like this: Declaration in resources: <MenuItem Command="MyCommands.CloneObject" CommandParameter="{Binding SelectedObject}" Header="Clone"> <MenuItem.Icon> <Image Source="Images\Clone.png" Height="16" Width="16"></Image> </MenuItem.Icon> </MenuItem> <MenuItem Command="MyCommands.RemoveCommand" CommandParameter="{Binding SelectedObject}" Header="Remove"> <MenuItem.Icon> <Image Source="Images\Remove.png" Height="16" Width="16"></Image> </MenuItem.Icon> </MenuItem> <Separator/> <MenuItem Command="MCommands.CreateChild" CommandParameter="{Binding SelectedObject}" Header="Create child"> <MenuItem.Icon> <Image Source="Images\Child.png" Height="16" Width="16"></Image> </MenuItem.Icon> </MenuItem> Usage: <ToolBar MenuItems(?)="{Reference to set of items}" ShowText(?)="false" /> and <ContextMenu MenuItems(?)="{Reference to set of items}" />
