  • Using JLists and ListModels

    - by devoured elysium
    I have defined a DirectoryListModel class that extends the AbstractListModel class from the Java Api. Internally, I have a list of File objects. I have defined the getElementAt(int index) method as: @Override public Object getElementAt(int index) { return directoryElements.get(index) } The problem is that when I try to run my JList with my DirectoryListModel, it is going to show up the full paths of files instead of just the filenames. I could change this code to: @Override public Object getElementAt(int index) { return directoryElements.get(index).getName(); } and it'd work wonders, but the problem is that in the onclick event I'll want to have the File objects so I can do some checking with them (check if they're directories, etc). If I make getElementAt() return a String, I'm losing that possibility, thus I'd like to konw if there is a way I can format my File objects before the JList shows them in my window. Thanks

  • OpenGL game written in C with a Cocoa front-end I want to port to Windows

    - by Philip
    Hello, I'm wondering if someone could offer me some tips on how to go about this. I have a MacOS X OpenGL game that is written in very portable C with the exception of the non-game-play GUI. So in Cocoa I set up the window and OpenGL context, manage preferences, registration, listen for keystrokes etc. But all of the drawing and processing of input is handled in nice portable C. So I want to port to Windows. I figured the obvious way to go about was to use the Win32 api. Then I started to read a primer on Win32 and began to wonder if maybe life isn't too short. Can I do this in C# (without converting the backend to C#)? I'd rather devote the time to learning C# than Win32. Any suggestions would be most welcome. I really don't know a lick about Windows. The last version I regularly used was 3.1...

  • Writing jQuery functions that allow chaining.

    - by Rich Bradshaw
    I want to write some code that allows me to replace jQuery's animate function with one that does different things, but still allows me to call a secondary function on completion. At the moment, I'm writing lots of code like this; if (cssTransitions) { $("#content_box").css("height",0); window.setTimeout(function() { secondFunction(); }, 600); } else { $("#content_box").animate({ height:0 }, 600, function() { secondFunction(); }); } I'd much rather write a function that looks like this: function slideUpContent(object) { if (cssTransitions) { object.css("height",0); // Not sure how I get a callback here } else { $("#content_box").animate({ height:0 }, 600, function() { }); } } That I could use like this: slideUpContent("#content_box", function(){ secondFunction(); }); But I'm not sure how to get the functionality I need - namely a way to run another function once my one has completed. Can anyone help my rather addled brain?

  • Java: how to take a screenshot fast

    - by user350789
    I am implementing a simple eye tracker, which requires fast screenshoting of what is happening on the screen simultaneously with capturing the video from webcam. The thing is that the way of doing it with Robot, mentioned here: http://stackoverflow.com/questions/2475303/java-library-for-capturing-active-window-screenshot is extremely slow. By the way, retrieving the video from a webcam works much faster and returns the byte array, which is very fast to be processed. Does anybody know a faster solution? C++ libraries, which can be linked to Java for doing this may help as well. Thank you!

  • Why is this javascript function so slow on Firefox?

    - by macrael
    This function was adapted from the website: http://eriwen.com/javascript/measure-ems-for-layout/ function getEmSize(el) { var tempDiv = document.createElement("div"); tempDiv.style.height = "1em"; el.appendChild(tempDiv); var emSize = tempDiv.offsetHeight; el.removeChild(tempDiv); return emSize; } I am running this function as part of another function on window.resize, and it is causing performance problems on Firefox 3.6 that do not exist on current Safari or Chrome. Firefox's profiler says I'm spending the most time in this function and I'm curious as to why that is. Is there a way to get the em size in javascript without doing all this work? I would like to recalculate the size on resize incase the user has changed it.

  • How does transmission created it's cross plataform app? It has from Qt/Mac to CLI interfaces!

    - by Somebody still uses you MS-DOS
    I'm amazed at Transmission, a BT client. It has a Mac, a GTK+, a QT, a Web Client and a CLI interface to it. I tried reading some of it's source to understand how he creates all these interfaces, but no luck. Does the developer creates them using a single ide? Or does he create the interface logic in each specific environment (specially mac), "exports" this window code and integrates with the main logic? How did the developers create this software with so many interfaces?

  • How do I add items to the Finder context menu in Mac OS X?

    - by mystro
    I'm in the process of porting a Windows application to OS X (we wrote it in Java so most of the code is portable), but what I'm currently unsure of is how to add context menu items in the Finder window when the user right clicks on an item (i.e. I wish to add some items to the the menu that has "Open" "Open with" , "Get Info", etc... when the user right clicks). Most of the articles I've found deal specifically with Windows (I've searched for "context menus" and "shell extension", but I believe I may be searching the wrong terms), so I'm curious as to how to go about adding this in Mac or what literature I should be reading.

  • IE8 is still caching my requests even with mathrandom.

    - by Ozaki
    TLDR IE is still caching my requests even with Math.random() included in the URL. So I added math random onto the end of my url: var MYKMLURL = 'http://' + host + 'data/pattern?key='+ Math.random(); I also added math random onto my function param: window.setTimeout(RefreshPatternData, 1000, MYKMLLAYER); function RefreshPatternData(layer) { layer.loaded = false; layer.setVisibility(true); layer.refresh({ force: true, params: { 'key': Math.random()} }); setTimeout(RefreshPatternData, 30000, MYKMLLAYER); } So the request appears as http://host/data/pattern?key=35678652545 etc. It changes everytime the request is made. It works in Firefox & Chrome & Safari etc. But IE8 is still caching the data and not updating my layer. Any ideas as to why this might be occuring?

  • ajax not working in codeigniter

    - by user1800797
    I'm trying to send a post request using the ajax jquery function and return some data into a window asynchronously. Here's what I have so far. It doesn't seem to be working. in the view: $.ajax({ url: '/dashboard/presskits/media/get_video_link/', type: 'POST', dataType: 'json', data: { encoded_link : encoded_link }, cache: false, success: function(output_string){ // $('#edit_video_info').append(output_string); alert(output_string.url_data); } // End of success function of ajax form }); // End of ajax call }); in the controller: public function get_video_link() { $temp_url = $this->input->post('encoded_link'); $output_string = json_encode(array('url_data' => $temp_url)); return $output_string; }

  • How do I change the Unit:Characters in Matlab?

    - by Jonas
    For portability, I set the units of my GUIs to 'characters'. Now I have a user who wants to use Matlab on his netbook, and the GUI window is larger than the screen (and thus cropped at the top). I think I could try and write something in the openingFcn of the GUI that measures screen size and then adjusts the GUI accordingly, but I'd rather avoid that, because I then need to deal with text that is bigger than the text boxes, etc. What I'd rather like to do is somehow adjust the unit 'character' on his Matlab installation. None of the font sizes in the preferences seem to have an effect on unit:character, though. Does anyone know whether there's a setting for that, which can be changed from within Matlab (I don't mind if it's something that is reset at every reboot, since I can just put it into the startup script)?

  • How do I replace "this" in Java with something that works.

    - by Luke Alderton
    I'm looking to get the showGUI() method work, the compiler says "this" is not a static variable and cannot be referenced from a static context, what would I use to replace "this"? I've tried test.main (test being the package it's in). The reason I'm using the static method showGUI() is because I need the method to be called from another static method, as well as the startup() method. Below are my two main classes. public class Main extends SingleFrameApplication { @Override protected void startup() { showGUI(); } @Override protected void configureWindow(java.awt.Window root) { } public static Main getApplication() { return Application.getInstance(Main.class); } public static void main(String[] args) { launch(Main.class, args); } public static void showGUI() { show(new GUI(this)); } } public class GUI extends FrameView { public GUI(SingleFrameApplication app) { super(app); initComponents(); } private void initComponents() { //all the GUI stuff is somehow defined here } }

  • javascript location.hash refreshing in IE

    - by aepheus
    I need to modify the hash, remove it after certain processing takes place so that if the user refreshes they do not cause the process to run again. This works fine in FF, but it seems that IE is reloading every time I try to change the hash. I think it is related to other things that are loading on the page, though I am not certain. I have an iframe that loads (related to the process) as well as some scripts that are still being fetched in the parent window. I can't seem to figure out a good way to change the hash after all the loading completes. And, at the same time am not even positive that it is related to the loading. Any ideas on how to solve this?

  • Program output to file in Java (and reading it again)

    - by Cohagen
    I have a large main method in an IO class which creates objects from four different classes in my program (which all use one another to some extent). My main method takes all info in using a scanner, from the console window, and uses this info to call the constructors and methods in the other classes. As this is my first full program in Java I have been focussed on making the main method work via the console, without properly considering file input and output. I cannot see an easy way of making that work now. Ideally what I require is some way of writing everything I input to the console while running the main method to a file, in a format that can be read again and inputed back through the main method? I have refrained from posting the main method as it is 250+ lines long, but will post any relevant parts of it if required. Any help appreciated

  • How to to dump JS array... (boommarklet?)

    - by Soulhuntre
    A page on a site I use is holding some of my data hostage. Once I have logged into the site and navigated to the right page, the data I need is in the array eeData[] - it is 720 elements long (once every 2 minutes of a given day). Rather than simulate the requests to the underlying stuff json supplier and since its only once a day, I am happy to simply develop a bookmarklet to grab the data - preferably as a XML or CSV file. Any pointers to sample code or hints would help. I found a bookmarklet here that is based on this script that does part of this - but I am not up to speed on any potential JS file IO to see if it is possible to induce a file "download" of the data, or pop it opn in a new window I can copy / paste.

  • wxPython formatting questions

    - by Kevin
    I have an app I was working on to learn more about wxPython( I have been primarily been a scripter ). I forgot about it now I am opening it back up. It's a screen scraper, and I have it working almost the way I want it, going to build a regex parser to strip out the links in every scrape that I don't need. The questions I have are this. In it current state, if I check more than one site, it goes out and scrapes, and returns it in separate windows, the for:each section in the Clicked function. I want to put them in a frame, in the window, altogether. I also want to know if I can take the list they are read into and send it to a checklist, so someone could check off separate items, I want to build a save function and keep certain ones. In regards to a save function, I want to keep saved checks, are there calls to the widgets to save their states? I know it's a lot, but thanks for the help.

  • How to avoid lost calls to an external JS file before loading it.

    - by David
    Hi, My issue is that multiple websites are going to include my JS file and when calling something like this: <script src="..."></script> hello.say("yay"); there going to be a race issue so sometimes it could make it sometimes not. i know that i can solve that easily by putting every function in a window.onload but that wouldn't be clean as i've seen other websites magically solve that like google analytics: .. Calling google analytics JS.. <script type="text/javascript"> try{ var pageTracker = _gat._getTracker("UA-xxxxxx-x"); <-- this an object ! pageTracker._trackPageview(); } catch(err) {} </script> How to do that?

  • getting the url of the page and the url of the selected hyperlink

    - by Dan
    Hi This is pretty hard to explain but i'll give it a shot. Working with Safari to create an extension as is now possible with Safari 5 - how would I go about getting the URL of the current page with using JavaScript and the Safari API? I would also like to be able to get a hyperlink that is selected. For instance in Safari when you right click on a hyperlink and it says open in a new tab, open in a window etc - clicking opens that hyperlink. What part of the API is used to get access to the link itself, and how does it know its a link in the first place? I hope thats clear enough. Thanks
