  • How to shift pixels of a pixmap efficient in Qt4

    - by stanleyxu2005
    Hello, I have implemented a marquee text widget using Qt4. I painted the text content onto a pixmap first. And then paint a portion of this pixmap onto a paint device by calling painter.drawTiledPixmap(offsetX, offsetY, myPixmap) My Imagination is that, Qt will fill the whole marquee text rectangle with the content from myPixmap. Is there a ever faster way, to shift all existing content to left by 1px and than fill the newly exposed 1px wide and N-px high area with the content from myPixmap?

  • Checking if radio buttons are checked in Firefox

    - by Andrew Song
    On my site, I have two checkboxes created in my ASP.NET MVC view like so: Html.RadioButton("check", "true", "true" == (string) ViewData["someKey"], new { id = "check1"}); Html.RadioButton("check", "false", "false" == (string) ViewData["someKey"], new { id = "check2"}); I am positive that ViewData["someKey"] has the value "true" in it. In my JS init function, I perform the following check: alert($('#check1').is(':checked') + " " + $('#check2').is(':checked')); In Firefox (and only Firefox), my alert dialog will show the following (it works as expected in every other browser): Initial page load: true false Normal refresh via Ctrl + R: false false Refresh skipping cache via Ctrl + Shift + R: true false I have tried many different methods of looking at the checkbox value, including $('#check1').attr('checked') without success. If I examine the HTML in Firebug, I can see that the first radio button has the property checked="checked" in it. Why is the checkbox value changing in FF when I refresh, and how can I mitigate this? Since this seems to be a FF-only bug, how can I change my code to make it work? This SO question seemed to ask something similar, but none of the proposed solutions seem to work in this case. Edit: I should also point out that when the radio button is rendered after the refresh in FF, it's not actually being displayed as checked either, despite what the HTML is telling me. Edit2: Adding raw HTML as per request <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/>

  • jQuery Checkbox Error

    - by Zack Fernandes
    Hello, I am working on a jQuery-based todo list interface, and have hit a bit of a wall. The jQuery I am working with is a bit hacked together from various tutorials I have read, as I'm a bit of a beginner. $('#todo input:checkbox').click(function(){ var id = this.attr("value"); if(!$(this).is(":checked")) { alert("Starting."); $.ajax({ type: "GET", url: "/todos/check/"+id, success: function(){ alert("It worked.") } }); } }) This is the HTML I am using, <div id="todo"> <input type="checkbox" checked="yes" value="1"> Hello, world. <br /> </div> Any help on this would be greatly appreciated. For reference, thereason I have alerts in the jQuery is for debugging. The reason I can tell the code isn't working is because I am not getting these alerts. Thanks.

  • Passing data between objects in Chain of Responsibility pattern

    - by AbrahamJP
    While implementing the Chain of Responsibility pattern, i came across a dilemma om how to pass data between objects in the chain. The datatypes passed between object in the chain can differ for each object. As a temporary fix I had created a Static class containing a stack where each object in the chain can push the results to the stack while the next object in the chain could pop the results from the stack. Here is a sample code on what I had implemented. public interface IHandler { void Process(); } public static class StackManager { public static Stack DataStack = new Stack(); } //This class doesn't require any input to operate public class OpsA : IHandler { public IHandler Successor {get; set; } public void Process() { //Do some processing, store the result into Stack var ProcessedData = DoSomeOperation(); StackManager.DataStack.Push(ProcessedData); if(Successor != null) Successor(); } } //This class require input data to operate upon public class OpsB : IHandler { public IHandler Successor {get; set; } public void Process() { //Retrieve the results from the previous Operation var InputData = StackManager.DataStack.Pop(); //Do some processing, store the result into Stack var NewProcessedData = DoMoreProcessing(InputData); StackManager.DataStack.Push(NewProcessedData); if(Successor != null) Successor(); } } public class ChainOfResponsibilityPattern { public void Process() { IHandler ProcessA = new OpsA(); IHandler ProcessB = new OpsB(); ProcessA.Successor = ProcessB; ProcessA.Process(); } } Please help me to find a better approach to pass data between handlers objects in the chain.

  • Adding select menu default value via JS?

    - by purpler
    Hi, i'm developing a meta search engine website, Soogle and i've used JS to populate select menu.. Now, after the page is loaded none of engines is loaded by default, user needs to select it on his own or [TAB] to it.. Is there a possibility to preselect one value from the menu via JS after the page loads? This is the code: Javascript: // SEARCH FORM INIT function addOptions(){ var sel=document.searchForm.whichEngine;for(var i=0;i<arr.length;i++){ sel.options[i]=new Option(arr[i][0],i)}} function startSearch(){ searchString=document.searchForm.searchText.value;if(searchString!=""){ var searchEngine=document.searchForm.whichEngine.selectedIndex; var finalSearchString=arr[searchEngine][1]+searchString;location.href=finalSearchString}return false} function checkKey(e){ var character=(e.which)?e.which:event.keyCode;if(character=='13'){ return startSearch()}} // SEARCH ENGINES INIT var arr = new Array(); arr[arr.length] = new Array("Web", "http://www.google.com/search?q="); arr[arr.length] = new Array("Images", "http://images.google.com/images?q="); arr[arr.length] = new Array("Knoweledge","http://en.wikipedia.org/wiki/Special:Search?search="); arr[arr.length] = new Array("Videos","http://www.youtube.com/results?search_query="); arr[arr.length] = new Array("Movies", "http://www.imdb.com/find?q="); arr[arr.length] = new Array("Torrents", "http://thepiratebay.org/search/"); HTML: <body onload="addOptions();document.forms.searchForm.searchText.focus()"> <div id="wrapper"> <div id="logo"></div> <form name="searchForm" method="POST" action="javascript:void(0)"> <input name="searchText" type="text" onkeypress="checkKey(event);"/> <span id="color"></span> <select tabindex="1" name="whichEngine" selected="Web"></select> <br /> <input tabindex="2" type="button" onClick="return startSearch()" value="Search"/> </form> </div> </body>

  • SSH with Perl using file handles, not Net::SSH

    - by jorge
    Before I ask the question: I can not use cpan module Net::SSH, I want to but can not, no amount of begging will change this fact I need to be able to open an SSH connection, keep it open, and read from it's stdout and write to its stdin. My approach thus far has been to open it in a pipe, but I have not been able to advance past this, it dies straight away. That's what I have in mind, I understand this causes a fork to occur. I've written code accordingly for this fork (or so I think). Below is a skeleton of what I want, I just need the system to work. #!/usr/bin/perl use warnings; $| = 1; $pid = open (SSH,"| ssh user\@host"); if(defined($pid)){ if(!$pid){ #child while(<>){ print; } }else{ select SSH; $| = 1; select STDIN; #parent while(<>){ print SSH $_; while(<SSH>){ print; } } close(SSH); } } I know, from what it looks like, I'm trying to recreate "system('ssh user@host')," that is not my end goal, but knowing how to do that would bring me much closer to the end goal. Basically, I need a file handle to an open ssh connection where I can read from it the output and write to it input (not necessarily straight from my program's STDIN, anything I want, variables, yada yada) This includes password input. I know about key pairs, part of the end goal involves making key pairs, but the connection needs to happen regardless of their existence, and if they do not exist it's part of my plan to make them exist.

  • Windows Mobile: "My network card connects to" registry settings

    - by Martin Robins
    Can anybody please tell me the registry setting(s) that are affected in Windows Mobile 6.1 when a user selects Start - Settings - Connections - Wi-Fi and then changes the value of the "My network card connects to" drop down list on the "Network Adapters" tab? I have a device that seems to default this to "The Internet" when in fact the Wi-Fi connects to the corporate network and I would like to be able to change this programatically rather than expecting 250+ users to have to do it manually every time they reboot their devices. Thanks.

  • iPhone - How do I find the MAC address of the connected WiFi access point?

    - by Ciaran
    Without using the private APIs, is it possible to programatically determine the MAC address of the access point that the iPhone is connected to? I understand that this should be doable using the core BSD libraries, but we are new to this, so it would be great if someone can point us to some starter code. Note: we're trying to determine the MAC address of the remote device - not the MAC address of the iPhone.

  • Using javascript and php together

    - by EmmyS
    I have a PHP form that needs some very simple validation on submit. I'd rather do the validation client-side, as there's quite a bit of server-side validation that happens to deal with writing form values to a database. So I just want to call a javascript function onsubmit to compare values in two password fields. This is what I've got: function validate(form){ var password = form.password.value; var password2 = form.password2.value; alert("password:"+password+" password2:" + password2); if (password != password2) { alert("not equal"); document.getElementByID("passwordError").style.display="inline"; return false; } alert("equal"); return true; } The idea being that a default-hidden div containing an error message would be displayed if the two passwords don't match. The alerts are just to display the values of password and password2, and then again to indicate whether they match or not (will not be used in production code). I'm using an input type=submit button, and calling the function in the form tag: <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" onsubmit="return validate(this);"> Everything is alerting as expected when entering non-matching values. I would have hoped (and assumed, based on past use) that if the function returned false, the actual submit would not occur. And yet, it is. I'm testing by entering non-matching values in the password fields, and the alerts clearly show me the values and the not equal result, but the actual form action is still occurring and it's trying to write to my database. I'm pretty new at PHP; is there something about it that will not let me combine with javascript this way? Would it be better to use an input type=button and include submit() in the function itself if it returns true?

  • How to write a flexible modular program with good interaction possibilities between modules?

    - by PeterK
    I went through answers on similar topics here on SO but could't find a satisfying answer. Since i know this is a rather large topic, i will try to be more specific. I want to write a program which processes files. The processing is nontrivial, so the best way is to split different phases into standalone modules which then would be used as necessary (since sometimes i will be only interested in the output of module A, sometimes i would need output of five other modules, etc). The thing is, that i need the modules to cooperate, because the output of one might be the input of another. And i need it to be FAST. Moreover i want to avoid doing certain processing more than once (if module A creates some data which then need to be processed by module B and C, i don't want to run module A twice to create the input for modules B,C ). The information the modules need to share would mostly be blocks of binary data and/or offsets into the processed files. The task of the main program would be quite simple - just parse arguments, run required modules (and perhaps give some output, or should this be the task of the modules?). I don't need the modules to be loaded at runtime. It's perfectly fine to have libs with a .h file and recompile the program every time there is a new module or some module is updated. The idea of modules is here mainly because of code readability, maintaining and to be able to have more people working on different modules without the need to have some predefined interface or whatever (on the other hand, some "guidelines" on how to write the modules would be probably required, i know that). We can assume that the file processing is a read-only operation, the original file is not changed. Could someone point me in a good direction on how to do this in C++ ? Any advice is wellcome (links, tutorials, pdf books...).

  • Replacing a word in a text file with a value using python

    - by Jamde Jam
    I have been trying to replace a word in a text file with a value (say 1), but my outfile is blank.I am new to python (its only been a month since I have been learning it). My file is relatively large, but I just want to replace a word with the value 1 for now. Here is a segment of what the file looks like: NAME SECOND_1 ATOM 1 6 0 0 0 # ORB 1 ATOM 2 2 0 12/24 0 # ORB 2 ATOM 3 2 12/24 0 0 # ORB 2 ATOM 4 2 0 0 4/24 # ORB 3 ATOM 5 2 0 0 20/24 # ORB 3 ATOM 6 2 0 0 8/24 # ORB 3 ATOM 7 2 0 0 16/24 # ORB 3 ATOM 8 6 0 0 12/24 # ORB 1 ATOM 9 2 12/24 0 12/24 # ORB 2 ATOM 10 2 0 12/24 12/24 # ORB 2 #1 #2 #3 I want to first replace the word ATOM with the value 1. Next I want to replace #ORB with a space. Here is what I am trying thus far. input = open('SECOND_orbitsJ22.txt','r') output=open('SECOND_orbitsJ22_out.txt','w') for line in input: word=line.split(',') if(word[0]=='ATOM'): word[0]='1' output.write(','.join(word)) Can anyone offer any suggestions or help? Thanks so much.

  • How to pass data from selected rows using checkboxes from JSP to the server

    - by eddy
    Hi, I'd like to know if there's any way to send data to the server for the selected rows using the checkboxes I've put on those rows? I mean , how can I send only the data (in this case mileage ) of those selected rows (selected with the checkboxes) to the server ? see the image Here's the html code I use: <table> <thead> <tr class="tableheader"> <td width="10%"></td> <td width="30%">Vehicle</td> <td width="40%">Driver</td> <td width="10%">Mileage</td> </tr> </thead> <tbody> <c:forEach items="${list}" var="item"> <tr> <td align="center"> <input type="checkbox" name="selectedItems" value="c:out value="${item.numberPlate}"/>"/> </td> <td align="left"><c:out value="${item.numberPlate}"/></td> <td align="left"><c:out value="${item.driver.fullName}" /></td> <td align="left"><input type="text" name="mileage" value="" /></td> </tr> </c:forEach> </tbody> </table> I really hope you can give some guidance on this.

  • How can the subView detect that the mainView is rotating?

    - by wolverine
    I have a mainView. To this view, I am adding a view of the same size. When the mainView(the background) rotates, its being detected but the subview doesnt have any idea about being rotated. And its functions are not even being called. Even when the program launches too, if I am in landscape mode, its the same way. How can I make the subView know that the device is being rotated?

  • Skipping the BufferedReader readLine() method in java

    - by DDP
    Is there a easy way to skip the readLine() method in java if it takes longer than, say, 2 seconds? Here's the context in which I'm asking this question: public void run() { boolean looping = true; while(looping) { for(int x = 0; x<clientList.size(); x++) { try { Comm s = clientList.get(x); String str = s.recieve(); // code that does something based on the string in the line above } // other stuff like catch methods } } } Comm is a class I wrote, and the receive method, which contains a BufferedReader called "in", is this: public String recieve() { try { if(active) return in.readLine(); } catch(Exception e) { System.out.println("Comm Error 2: "+e); } return ""; } I've noticed that the program stops and waits for the input stream to have something to read before continuing. Which is bad, because I need the program to keep looping (as it loops, it goes to all the other clients and asks for input). Is there a way to skip the readLine() process if there's nothing to read? I'm also pretty sure that I'm not explaining this well, so please ask me questions if I'm being confusing.

  • Combining the jquery Calendar picker with the jquery validation and getting them to play nice?

    - by MBonig
    I'm just starting to get into jquery/javascript programming so this may be a beginner question but I sure can't seem to find anything about it. I have a text field on a form. I've used the JQuery UI Calendar picker to make data entry better. I've also added jquery validation to ensure that if the user enters the date by hand that it's still valid. Here is the html: <input class="datepicker" id="Log_ServiceStartTime_date" name="Log_ServiceStartTime_date" type="text" value="3/16/2010"></input> and javascript: $('form').validate(); $('#Log_ServiceStartTime_date').rules('add','required'); $('#Log_ServiceStartTime_date').rules('add','date'); the problem I'm having is this: If a user puts in a bad date, or no date at all, the validation correctly kicks in and the error description displays. However, if the user clicks on the textbox to bring up the calendar picker and selects a date, the date fills into the field but the validation does not go away. If the user clicks into the textbox and then back out, the validation correctly goes away. How can I get the calendar picker to kick off the validation routine once a date is selected? thanks
