  • setup Qt and PyQt on mac osx so my app can also deployable on windows

    - by hk_programmer
    Hi, I've been coding with Python and C++ and now need to work on building a gui for data visualization purposes. I work on Mac Snow Leopard (intel), python 3.1 using gcc 4.2.1 (from Xcode 3.1) I wanted to first install Qt and then PyQt. And my goals are to be able to: - quickly prototype GUI and the accompanied logic that drives the GUI using PyQt and python - if I decided I need the speed, or if it's fairly easy to translate my GUI into C++ using the Qt tools, I have the options to translate my app into C++ - Be able to deploy my application onto Windows (both the python and c++ version of my app) Give the goals above, what are the correct steps I should take and what issues i should be aware of when setting up Qt and PyQt. Which other deployment tools do I need? From my readings so far, here's what I have: download the Qt source for mac and configure it with -platform macx-g++42 -arch x86_64 -no-framework (i've read somewhere that building as framework causes some trouble in deployment and/or debugging, can't find the article anymore) download latest SIP source and build download latest PyQt and build from source (any special options I should pay attention to?) For deployment, I've read that I would need to use py2exe/cx_freeze for windows, p2app for mac: http://arstechnica.com/open-source/guides/2009/03/how-to-deploying-pyqt-applications-on-windows-and-mac-os-x.ars but seems like what the article describe is deploying an app you build on windows on the windows platform and vice versa. How do you deploy to windows (is it even possible?) if you are writing your Qt app on a mac ? Really appreciate the help

  • How to find whole graph coverage path in dynamic state-flow diagram?

    - by joseph
    Hello, As I've been researching algorithms for path finding in graph, I found interesting problem. Definition of situation: 1)State diagram can have p states, and s Boolean Fields, and z Int Fields 2)Every state can have q ingoing and r outgoing transitions, and h Int fields (h belongs to z - see above) 3)Every transition can have only 1 event, and only 1 action 4)every action can change n Boolean Fields, and x Int Fields 5)every event can have one trigger from combination of any count of Boolean Fields in diagram 6)Transition can be in OPEN/CLOSED form. If the transition is open/closed depends on trigger2 compounded from 0..c Boolean fields. 7) I KNOW algorithm for finding shortest paths from state A to state B. 8) I KNOW algorithm for finding path that covers all states and transitions of whole state diagram, if all transitions are OPEN. Now, what is the goal: I need to find shortest path that covers all states and transitions in dynamically changing state diagram described above. When an action changes some int field, the algorithm should go through all states that have changed int field. The algorithm should also be able to open and close transition (by going through transitions that open and close another transitions by action) in the way that the founded path will be shortest and covers all transitions and states. Any idea how to solve it? I will be really pleased for ANY idea. Thanks for answers.

  • Copy folder contents using VBScript

    - by LukeR
    I am trying to copy the contents of certain folders to another folder using VBScript. The goal is to enumerate a user's AD groups and then copy specific folder content based on those groups. I have code, which is currently not working. Dim Group,User,objFSO,objFolder,source,target,StrDomain StrDomain = "domain.local" FolderBase = "\\domain.local\netlogon\workgrps\icons" Set net = CreateObject("wscript.network") Struser = net.username target = "\\fs1\users\"&net.username&"\Desktop\AppIcons\" DispUserInWhichGroup() Function DispUserInWhichGroup() On Error Resume Next Set objFSO=CreateObject("Scripting.FileSystemObject") Set User = GetObject("WinNT://" & strDomain & "/" & strUser & ",user") For Each Group In User.Groups source = FolderBase & Group.name Set objFolder = GetFolder(source) For Each file in objFolder.Files objFSO.CopyFile source &"\"& file.name, target&"\"&file.name Next Next End Function This has been cobbled together from various sources, and I'm sure most of it is right, I just can't get it working completely. Any assistance would be great. Cheers.

  • cannot print popup displaying pdf file

    - by user369544
    I have a php file with the following code: <?php ?> <form action="" id="f1" name="f1"> <input type="button" name="preview" value="Open PDF" onclick="showPDF()" /> </form> <script type="text/javascript" src="jquery-1.4.2.min.js"></script> <script type="text/javascript"> function showPDF(){ var newwin=window.open("pdf.pdf","Window1","menubar=no,width=430,height=360,toolbar=no"); newwin.print(); } </script> It opens up a popup window with pdf file inside it BUT fails to open the print dialog box. But the same code without the pdf filename i.e var newwin=window.open("","Window1","menubar=no,width=430,height=360,toolbar=no"); opens up the popup window and show the print dialog box. Can anybody provide me a solution to this

  • Xcode Code Sense horribly broken?

    - by Philippe Leybaert
    Ever since I started using Xcode, I've experienced extremely annoying problems using Xcode and Code Sense. The problem is that when Code Sense kicks in for code completion, sometimes the source code text below the line I'm working on goes "crazy". If I continue typing, the problem gets worse, and after a while the source code is completely screwed up (funny colors, missing lines and characters, ...). Strange enough, the source code itself is unaffected, because when I select another source file and then go back to the one I was working on, everything looks fine again. The problem can be seen in this screencast: http://www.screencast.com/t/OGY3NWE5 Interesting facts: This problem has occurred on 3 different machines, so it's not related to a corrupt installation. Sometimes it's fine for a while (up to one hour) after launching Xcode, but once it starts happening, it's getting worse and worse, until Xcode is restarted. Then it's fine again (for a while) I've searched the web for similar experiences, and I can't find anything. I would think that it is a known problem, since it occurs on 3 different Macs here (both running 10.5 and 10.6). Anyone having the same problems? Or a suggestion for fixing this?

  • javascript window.close, once again

    - by John Kjøller
    Im sorry if I havent done my research properly, - but couldnt find the answer I needed, so here goes: From my main page I open a new window using mainPlayer = window.open(); This window stays open until user clicks on a mainPlayer.close(); event. (or simply x closes the window) However, the idea is to make it possible to let the player keep playing, while browsing around the rest of the pages. But as soon as the user leaves the page that opened the mainPlayer window, the reference to the mainPlayer window seem to be lost. How do I, from the site's other pages, check if the mainPlayer window is open and close it on a click event? Thx John

  • How do I avoid killing the native controls on a html5-video when i've started it programmaticly?

    - by Nils
    OK, so the deal is I've started making a little videoplayer, that works by clicking a div with an image, expanding the div and the image, and then exchanges the image with a html5-videotag. the code is as below. (It's very early on, so i know theres a lot that need improving, as in not using javascript to set styles and so on, but nevertheless, any insigts and tips are welcome, besides the answer to the main question) /*Begin Expander*/ var $videoplayer = $('<video width="640" height="360" preload="none" controls="" tabindex="0" style="position: relative;"><source type="video/mp4" src="/restalive/movies/big_buck_bunny.mp4"></source><source type="video/ogg" src="/restalive/movies/big_buck_bunny.ogv"></source></video>').appendTo('body'); $videoplayer.hide(); $(".ExpandVideo").each(function(i){ var $trigger = $(this); var $image = $trigger.find("img"); $image.css({ "width" : "100%" ,"height" : "auto" }) $trigger.css({ "display" : "block" ,"overflow" : "hidden" ,"width" : "200px" ,"float" : "left" }); $trigger.bind("click", function(e){ $trigger.animate({"width" : "640px"}, "fast", function(){ $image.replaceWith($videoplayer); $videoplayer.show(); $videoplayer.attr("id", "video" + i); var video = document.getElementById("video" + i); video.play(); }) }) }); However, the main problem is that when i've fired of the video like this (video.play()), the native controls stop working, i can no longer pause the video, even though the controls are there, and clickable, the video just starts playing immidiatley again when i trie to pause it. Which is a shame, because i want to use the native controls for simplicity.

  • Image swaping with click on <tr>

    - by Jonny Sooter
    I've edited this piece of code from the Data Tables Plugin witch makes a tr click able and pops open another tr with details from the clicked tr. This piece of code is the event listener for opening and closing. When "details" are open the img should be images/details_close.png and they are closed the img should be images/details_open.png and have a swap occurring when it opens and closes when clicked. What is happening is there is no swap going on when its open or closed I still only get the "details_open.png". I don't knoe if I'm just not selecting the img tag properly or whats going on. Link to project: http://www2.kent.k12.wa.us/ksd/it/www/mobile/elementary.html $('#example tbody').on('click', 'td', function (e) { var myImage = $(this).find("img"); var nTr = $(this).parents('tr')[0]; if ( oTable.fnIsOpen(nTr) ) { /* This row is already open - close it */ myImage.src = "images/details_open.png"; oTable.fnClose( nTr ); } else { /* Open this row */ myImage.src = "images/details_close.png"; oTable.fnOpen( nTr, fnFormatDetails(oTable, nTr), 'details' ); } } );

  • How to modify the Title Bar text for SQL Server Management Studio?

    - by DaveDev
    Sometimes I keep multiple instances of SQL Server Management Studio 2005 open. I might have the dev database open in one, and the production database open in another. These appear in the Windows task bar with the text "Microsoft SQL Serve...", which means it's impossible to differentiate between them unless I open the window and scroll the Object Explorer up to see what server the window is actually connected to. Is ther any way that I can get the window to display the server name first, and then the name of the application? Like "Dev-DB.database_name - Microsoft SQL Serve..." or whatever?

  • How to make a custom ear file in maven

    - by Zombies
    Here is my challenge, I need to make an ear file for a specific container. To be more specific on how this ear will be created: This is a standard j2ee ear file, with 1 WAR in it. The container it is deployed to will expect certain xml files (which can easily be found (somewhere) inside the source project). Here are my obstacles The source folder contains various container specific xml files. But, these files do not map directly to where the container expects them inside the EAR file. For example, there will be a file that this container expects to be in 'EARFILE.ear/config/connections.xml'. But this file is located (in the source) at /some/obscure/unrelated/directory. This is the case for about 5-7 files. I cannot change the original source project layout at all. So, how can I create the compliant EAR file that I need. There is NO plugin at this time for the container that I am using, I have certainly looked.

  • How to load MS Word document in C# (.NET)?

    Hi, How do I load MS Word document (.doc and .docx) to memory (variable) without doing this?: wordApp.Documents.Open I don't want to open MS Word, I just want that text inside. You gave me answer for DOCX, but what about DOC? I want free and high performance solution - not to open 12.000 instances of Word to process all of them. :( Aspose is commercial product, and 900$ is a way too much for what I do.

  • How reference popup object when opener page changes?

    - by achairapart
    This is driving me crazy! Scenario: The main page opens a pop-up window and later calls a function in it: newWin = window.open(someurl,'newWin',options); ...some code later... newWin.remoteFunction(options); and it's ok. Now, popup is still open and Main Page changes to Page 2. In Page 2 newWin doesn't exist anymore and I need to recreate the popup window object reference in order to call again the remote function (newWin.remoteFunction) I tried something like: newWin = open('','newWin', options); if (!newWin || newWin.closed || !newWin.remoteFunction) { newWin = window.open(someurl,'newWin',options); } And it works, I can call newWin.remoteFunction again BUT Safari for some reason gives Focus() to the popup window everytime the open() method is called breaking the navigation (I absolutely need the popup working in the background). Only workaround I can think to solve this is to create an interval in the popup with: if(window.opener && !window.opener.newWin) window.opener.newWin = self; and then set another interval in the opener Page with some try/catch but it is inelegant and very inefficient. so, I wonder, it's really so hard to get the popup object reference between different pages in the opener window?

  • How to Not alter font in webpage after opening a file (pdf or jpg) in ASP.NET C#? [closed]

    - by Victor
    Possible Duplicate: How to not alter font in webpage after opening a pdf in ASP.NET C#? Previously I posted this question: How to open files from a specific route in ASP-NET c#? in fact, I have already asked this however it was only a minor question so I guess it wasn't that important in the previous post, so I will ask here. Whenever I open a pdf with: Response.Write("<script>window.open('FilePath');</script>"); All of the font in the page is altered, example, the letter's size increases and some of the letter's colors are switched to black instead of the font that I assigned. Is there a way that I can work around that?? http://imageshack.us/a/img838/5145/beforeja.png http://imageshack.us/a/img546/4760/afterw.png Oh and I noticed that this also happens when you open images like jpg

  • jquery ui dialog - live not working?

    - by ile
    I'm using this dialog: http://docs.jquery.com/UI/Dialog To open dialog I do it this way: $('a.openModal').live("click", function() { var idArr = $(this).attr('id').split("OpenNote"); var id = idArr[1]; alert($(".modalNote#dialog-modal" + id).html()); $(".modalNote#dialog-modal" + id).dialog('open'); return false; }); This dialog is used to display content of note when title is clicked. When I generated html on pageload, then this works fine, but if I add html dynamically then dialog won't open. It is also not hidden when it's appended to div. Is it possible to open it "on-fly"?

  • How to launch new Firefox window with multiple tabs using Python

    - by newbie py
    Hi, I want to create a MSWindows Python program that would launch a new Firefox window with multiple tabs each time it is run. For example if I want to search "hello", a new window pops out (even if a Firefox window is already open) and then launches a Google and Bing tabs searching for "hello". If I change the keyword to "world", a new browser pops out again with Google and Bing tabs searching for "world". I've looked at the webbrowser module but couldn't get it to: 1. Launch a new browser when a browser is already open: e.g. webbrowser.open('http://www.google.com',new=1) will instead open a new tab 2. Launch multiple tabs simultaneously in the same window Appreciate the help. Thanks.

  • Majority Voting in perl?

    - by aliocee
    Hi, i have 5 files containing the same words, i want read each word in all files and decide the winning word by detecting the following characters in a word (*, #, $, &) and generate output file i can only have 2 winners for example: file1 we$ are* ... file2 we$ are* ... file3 we* are$ ... file4 we$ are$ ... file5 we# are& ... output file: we$ - we$ is the winner since it occur in 3 files. are*$ - are* and are$ are the winners since both occur 2 times. here is how i started: #!/usr/local/bin/perl -w sub read_file_line { my $fh = shift; if ($fh and my $line = <$fh>) { chomp($line); return $line; } return; } open(my $f1, "words1.txt") or die "Can't"; open(my $f2, "words2.txt") or die "Can't"; open(my $f3, "words3.txt") or die "Can't"; open(my $f4, "words4.txt") or die "Can't"; open(my $f5, "words5.txt") or die "Can't"; my $r1 = read_file_line($f1); my $r2 = read_file_line($f2); my $r3 = read_file_line($f3); my $r4 = read_file_line($f4); my $r5 = read_file_line($f5); while ($f5) { what can i do here to decide and write the winning word in the output file? $r1 = read_file_line($f1); $r2 = read_file_line($f2); $r3 = read_file_line($f3); $r4 = read_file_line($f4); $r5 = read_file_line($f5); } Thanks.

  • Can a function defined in a bookmarklet be called from a page-level script?

    - by Soviut
    I have a bookmarklet that needs to open a new window/tab. In order to avoid the popup blocker, I need to call the window.open() method directly in the bookmarklet ie: at the browser-level. However, I want to keep the bookmarklet updatable by loading external Javascript files. To do this, the bookmarklet needs to append script nodes to the DOM. If i were to put window.open() code in one of these externally loaded scripts, the popup blocker would block it since its page-level. What I want to know is if I can create a wrapper function around window.open() in my bookmarklet, then call it from the externally loaded script? What is the scope and what are the permissions on a wrap such as this?

  • Can I share code & resources between Android projects without using a library?

    - by Tom
    The standard advice for sharing code & resources between Android projects is to use a library. Personally I find this works poorly if (a) the shared code changes a lot, or (b) your computer isn't fast enough. I also don't want to get into deploying multiple APK's, which seems to be necessary when I use dependent projects (i.e. Java Build Path, Projects Tab). On the other hand, sharing a folder of source code by using the Eclipse linked source feature works great (Java Build Path, Source tab, Link Source button), but for these two issues: 1) I can't use the same technique to share resources. I can create the link to the resources parent folder but then things get wonky and the shared resources don't get compiled (I'm using ADT 21). 2) So then I settle for copying the shared resources into each project, but this doesn't work because either. The shared code can't import the copy of its resources because it doesn't know the package name of the project that uses it. The solution I've been using is to access the resources dynamically, but that has become cumbersome as the number of resources grows. So, I need a solution to either (1) or (2), or I'll have to go back to a library project. (Or maybe there is another option I haven't thought of?)
