  • PySide / PyQt QStyledItemDelegate list in table

    - by danodonovan
    Dear All, I'm trying to create a table of lists in Python with Qt (PySide/PyQt - matters not) and my lists are squashed into the table cells. Is there a way to get the list delegates to 'pop out' of their cells? I've attached a simple code snippet - replace 'PySide' with 'PyQt4' depending on your preference from PySide import QtCore, QtGui class ListDelegate(QtGui.QStyledItemDelegate): def createEditor(self, parent, option, index): editor = QtGui.QListWidget(parent) for i in range( 12 ): editor.addItem('list item %d' % i) return editor if __name__ == '__main__': import sys app = QtGui.QApplication(sys.argv) model = QtGui.QStandardItemModel(2, 2) tableView = QtGui.QTableView() delegate = ListDelegate() tableView.setItemDelegate(delegate) tableView.setModel(model) for row in range(2): for column in range(2): item = QtGui.QStandardItem( 'None' ) model.setItem(row, column, item) tableView.setWindowTitle('example') tableView.show() sys.exit(app.exec_()) If you hadn't guessed I'm pretty new to this Qt lark Thanks in advance, Dan

  • SQL: Gather right hand values from a join

    - by Max Williams
    Let's say a question has many tags, via a join table called taggings. I do a join thus: SELECT DISTINCT `questions`.id FROM `questions` LEFT OUTER JOIN `taggings` ON `taggings`.taggable_id = `questions`.id LEFT OUTER JOIN `tags` ON `tags`.id = `taggings`.tag_id I want to order the results according to a particular tag name, eg 'piano', so that piano is at the top, then by all the other tags in alphabetical order. Currently i'm using this order clause: ORDER BY (tags.name = 'piano') desc, tags.name Which is going completely wrong - the first results i get back aren't even tagged with 'piano' at all. I think my problem is that i need to group the tag names somehow and do my ordering test against that: i think that doing it against the straight tags.name isn't working due to the structure of the resultant join table (it does work if i just do a simple select on the tags table) but i can't get my head around how to fix it. grateful for any advice, max

  • How to make a POST request with python-webkit?

    - by shakaran
    Hi, I new using python + webkit. I need make a POST request with webkit, but I dont know how to it. I use python-webkit because my app load a form on the GUI (for vote, comments and send more data) and I need post all these data with a POST request and load the html result send for the server to my GUI app with python-webkit. I have only this example with urllib: #!/usr/bin/python import urllib2, urllib import httplib server = 'server.somesite.com' data = {'name' : 'shakaran', 'password' : 'Only_I_know'} d = urllib.urlencode(data) headers = {"Content-type": "application/x-www-form- urlencoded", "Accept": "text/plain"} conn = httplib.HTTPConnection(server) conn.request("POST", "/login.php", d, headers) response = conn.getresponse() if response.status == 200: print response.status, response.reason print response.getheaders() data = response.read() print data conn.close() I need a simple example with webkit.

  • iPhone sdk, at dismissModalViewcontrollerAnimated, the parent change y origin coordinate

    - by DigitalVanilla
    Hi guys, my first post here :) I'm having a small trouble with a small but boring problem. I have a view, with a NavigationController. I load in the NC a simple view. Inside this view there's abutton where I fire the presentModalView... in the main view, not on NC, but it's parent view: ABVIEW NC NEWVIEW new attach a presentModalView... on ABVIEW, so [abview present...]; No problem till now. When it's the time to dismiss, after the temporary window (let's calls it NOTES) disappear, my ABVIEW with all the subviews change Y position from 0 to 20, the same height of the status bar. I was looking everywhere and I'm sure it's a stupid thing, but I miss a bit of knowledge here and I have no idea where to find the solution. thanks in advance!

  • URLCache - iPhone SDK

    - by Kevin
    Hello everyone.. I need some help in using the NSURLCache to download a simple file. It would need to be saved in the Documents folder of the app. I have seen the URLCache example that apple presented, but I didn't find it useful since it was an image that was being shown. In addition there was some complex code on the modification date. I actually need something when the application opens it will begin the download process. Can someone guide me through just the download process of any file? Thanks Kevin

  • Incorrect value for sum of two NSIntegers

    - by Antonio
    Hi everybody: I'm sure I'm missing something and the answer is very simple, but I can't seem to understand why this is happening. I'm trying to make an average of dates: NSInteger runningSum =0; NSInteger count=0; for (EventoData *event in self.events) { NSDate *dateFromString = [[NSDate alloc] init]; if (event.date != nil) { dateFromString = [dateFormatter dateFromString:event.date]; runningSum += (NSInteger)[dateFromString timeIntervalSince1970]; count += 1; } } if (count>0) { NSLog(@"average is: %@",[NSDate dateWithTimeIntervalSince1970:(NSInteger)((CGFloat)runningAverage/count)]); } Everything seems to work OK, except for runningSum += (NSInteger)[dateFromString timeIntervalSince1970], which gives an incorrect result. If I put a breakpoint when taking the average of two equal dates (2009-10-10, for example, which is a timeInterval of 1255125600), runningSum is -1784716096, instead of the expected 2510251200. I've tried using NSNumber and I get the same result. Can anybody point me in the right direction? Thanks! Antonio

  • Redraw balloon tip and tooltip in C#?

    - by Rryk
    I wrote a C# application that is a simple countdown timer. I use it myself to keep track of cooking time (not to forget about boiling pasta) and other purposes. It works in the tray. When hovering the icon it shows remaining time as a tooltip. When clicked it shows remaining time in a balloon tip. I would like displayed time to be "ticking down", i.e. to update every second. How do I force update/redraw of the balloon and tool tip?

  • Django vs. Pylons

    - by Kenneth Reitz
    I've recently become a little frustrated with Django as a whole. It seems like I can't get full control over anything. I love Python to death, but I want to be able (and free) to do something as simple as adding a css class to an auto-generated form. One MVC framework that I have really been enjoying working with is Grails (groovy). It has a FANTASTIC templating system and it lets you really have full control as you'd like. However, I am beyond obsessed with Python. So I'd like to find something decent and powerful written in it for my web application development. Any suggestions? Pylons maybe?

  • Are primitive types garbage collected in Android?

    - by snctln
    I know this may be a dumb question, but my background is more in c++ and managing my own memory. I am currently cutting down every single allocation that I can from one of my games to try and reduce the frequency of garbage collection and perceived "lag", so for every variable that I create that is an Object (String and Rect for example) I am making sure that I create it before hand in my constructor and not create temporary variables in simple 10 line functions... (I hope that makes sense) Anyways I was working though it some more tonight and I realized that I may be completely wrong about my assumption on garbage collection and primitive types (int, boolean, float) are these primitive type variables that I create in a 10 line function that gets called 20 times a second adding to my problem of garbage collection? So a year ago every few seconds I would see a message in logcat like GC freed 4010 objects / 484064 bytes in 101ms Now I see that message every 15-90 seconds or so... So to rephrase my question: Are primitive types (int, float, boolean, etc) included when seeing this message?

  • A Scripting language for XNA

    - by RCIX
    I've written a game engine, which i want to integrate scripting into. However, i've looked at the available choices, which seem to be the following: Xnua Jint Managed Scripting The problems with those are (respectively): Built for XNA 1 -- there's an XNA 3.1 port but it's under the Apache license which i'm not sure is compatible with our goals (and it has a bit obtuse syntax) Appears to not properly use type-safe objects (e.g. ArrayList over generics) Is in beta, and only runs on XNA 3.0 So, to summarize my specific needs (in order of importance most to least): Needs to run on XNA 3.1 Needs to run on the XBox and Windows Should have a relatively simple API -- something closer to Jint's than Xnua's preferably uses Lua, C#, or similar languages Must be commercially sellable -- if some form of credit is needed, then that's fine. Are there any scripting solutions that meet my needs, or will i have to (eventually) roll my own?

  • Using a .txt file Resource in VB

    - by Tony C
    Right now i have a line of code, in vb, that calls a text file, like this: Dim fileReader As String fileReader = My.Computer.FileSystem.ReadAllText("data5.txt") data5.txt is a resource in my application, however the application doesn't run because it can't find data5.txt. I'm pretty sure there is another code for finding a .txt file in the resource that i'm overlooking, but i can't seem to figure it out. So does anyone know of a simple fix for this? or maybe another whole new line of code? Thanks in advance!

  • How can I de-install a Perl module installed via `cpan`?

    - by Kinopiko
    I am using Perl running in user space (not installed via root) and installing modules via the command-line cpan. I would like to know if there is a simple way to remove a module without having to do a lot of work deleting individual files. I searched for this question on the internet and found some answers, but the answers I've found seem to either discuss using the Perl package manager (specific for Microsoft Windows), otherwise operating-system specific (BSDpan), suggesting using cpanplus (which I've had several bad experiences with), or ended by pointing to a dead link as follows: http://www.cpan.org/misc/cpan-faq.html#How_delete_Perl_modules. My question is specifically whether there is a clean way to remove a module installed via cpan.

  • MSSQL Efficiently dropping a group of rows with millions and millions of rows

    - by Net Citizen
    I recently asked this question: http://stackoverflow.com/questions/2519183/ms-sql-share-identity-seed-amongst-tables (Many people wondered why) I have the following layout of a table: Table: Stars starId bigint categoryId bigint starname varchar(200) But my problem is that I have millions and millions of rows. So when I want to delete stars from the table Stars it is too intense on MS SQL. I cannot use built in partitioning for 2005+ because I do not have an enterprise license. When I do delete though, I always delete a whole category Id at a time. I thought of doing a design like this: Table: Star_1 starId bigint CategoryId bigint constaint rock=1 starname varchar(200) Table: Star_2 starId bigint CategoryId bigint constaint rock=2 starname varchar(200) In this way I can delete a whole category and hence millions of rows in O(1) by doing a simple drop table. My question is, is it a problem to have thousands of tables in your MS SQL? The drop in O(1) is extremely desirable to me. Maybe there's a completely different solution I'm not thinking of?

  • how to debug ExceptionInInitializationError?

    - by grmn.bob
    I am getting an exception in a very simple 'study' application, so I expect the problem to be in my project setup, but I don't know how to debug ... What is the context of the exception, "ExceptionInInitializationError"? Where is it documented?

  • Viewing HTML inside Applet without using JEditorPane

    - by Tom
    Hello, I have a small (500kb) swing applet that displays very simple/limited set of small HTML page(s) inside it with JEditorPane, however this does not seem to work 100% fluently, some customers get a blank page displayed without any java exceptions. The page works OK from my machine. I need a more reliable way to show HTML page to all our users. Any ideas if there is a small + free class to use instead of JEditorPane OR is there an easy fix to make it more reliable (non blank) private JEditorPane m_editorPane = new JTextPane(); m_editorPane.setEditable( false); m_editorPane.setBackground(new Color(239 ,255, 215)); m_editorPane.setBounds(30,42,520,478 ); m_editorPane.setDoubleBuffered(true); m_editorPane.setBorder(null); m_editorPane.registerEditorKitForContentType("text/html", "com.xxxxx.SynchronousHTMLEditorKit"); m_editorPane.setPage(ResourceLoader.getURLforDataFile(param.trim()));

  • Problems with MVC Ajax.ActionLink and returning a PartialView

    - by mwright
    I'm trying to implement a simple Ajax update using MVC and have run into an issue. My understanding of how to implement Ajax with MVC is to use an Ajax.ActionLink which allows the content to be updated based on user interaction. I have an Ajax.ActionLink that looks like the following: <%= Ajax.ActionLink("Call Ajax", "Ajax", new AjaxOptions{UpdateTargetId = "updateDiv"}) %> If, in the controller, I return a string it works fine. However, when returning a PartialView instead, nothing happens. I can step through and verify that the controller is "returning" the partial view but nothing shows up in what I'm calling the updateDiv. How can I go about determining what the problem is?

  • A quick design question about C++ container classes in shared memory

    - by recipriversexclusion
    I am writing a simple wrapper around boost::interprocess's vector container to implement a ring buffer in shared memory (shm) for IPC. Assume that buf is an instance of RingBuffer created in shm. Now, in its ctor, buf itself allocates a private boost::interprocess::vector data member to store values, e.g. m_data. My question is: I think m_data should also be created in shared memory. But it this a necessity? What happens if buf that was created in shm itself, allocates standard memory, i.e. using new. Does this get allocated on the calling process's heap? I don't think buf is allocated there so how come a data member that is private to an object not on a process's heap gets allocated there. I'm confused.

  • How use applicationSettings in the new web.config configuration in VS2010?

    - by citronas
    I'm used to use web deployment projects. Currently I am developing a new web application with VS2010 and want to try to get along with the new web.config principle and deployment issues. How can I replace a simple setting like <applicationSettings> <NAMESPACE> <setting name="Testenvironment" serializeAs="String"> <value>True</value> </setting> </NAMESPACE> </applicationSettings> I want to have this setting to be set to True in Debug, and false in Release. How must the entries in the Web.Debug.config and Web.Release.Config look like? And by the way: Is there some documentation about the new web.config issue? Can't seem to google for the correct keywords.

  • Can you recommend a .net template engine?

    - by serg10
    I am looking for a .net templating engine - something simple, lightweight, stable with not too many dependencies. All I need it for at the moment is creating templated plain text and html emails. Can anyone give me a good recommendation? If it helps at all - something like Java's Freemarker or Velocity libraries. [UPDATE] Thanks for the answers so far - much appreciated. I am really intested in recommendations or war stories from when you have used these libraries. Seems to be the best way to make a decision without trying each in turn.

  • Can I use ido-completing-read instead of completing-read everywhere?

    - by haxney
    I'm a big fan of ido-mode, so much so that I would like to use it for things like describe-function or find-tag and so on, without having to write something like in "Can I get ido-mode-style completion for searching tags in Emacs?" for each one. Both (defalias completing-read ido-completing-read) and (setf 'completing-read 'ido-completing-read) don't work, at least partly because ido-completing-read calls completing-read in its body, so any simple redefinition would result in infinite recursion. In theory, it should be possible, since the first line of the docstring for ido-completing-read is "Ido replacement for the built-in completing-read." I've looked around a bit and can't seem to find anyone else who has attempted or succeeded at it. I realize that Icicles [2] probably provides something like this, and I may end up going with that anyway, but it is a bit more of a plunge than I care to take right now. Thanks for any help.

  • Multiple MCs, Single Listener, AsBroadcaster

    - by Brett
    I'm currently working trying to have multiple MCs inside a container MC which when they mini MCs are clicked will broadcast a message so that I can act upon them. This would be simple in AS 3 as it would be mc.addEventListener(MouseEvent.CLICK, obj); however, this is AS 2 and so I am semi-forced to use the broadcastMessage('myMessage'); and mc.addListener(obj); event handler. The main problem is that the broadcaster isn't broadcasting any messages. The second problem is that there are 5 MCs and when I click one of them, I get 5 trace messages about the click. I can't seem to keep the MC clicks unique even though they are all given separate instance names vie the properties panel. Any help would be appreciated. A link to my code is here (pastie.org #481511). Can you see anything wrong?

  • Java .doc generation

    - by bozo
    Hi, anyone knows an easy method to generate mail merge .doc file from Java? So, I want to create a Word (95/97) document in Word, put some simple placeholders in it (only single value, no iterators and other advanced tags) like the ones used with mailmerge option, and then at runtime replace those placeholders with values from Java. One option is to use Jasperreports, but this would require that I create exact replica of non-trivial Word document in Jasper format, which is not easy and is hard to change later. Is there some method of filling placeholders in Word from Java, which does not require low-level document alteration with positioning and others low-level .doc tags from code, but something like this: docPreparer.fillPlaceholder('placeholder1', 'my real value from runtime'); Some CRMs do this via ActiveX control for internet explorer, and it works great (they use Word's mailmerge) but I need an all-Java solution. Ideas? Thanks, Bozo

  • Non-reentrant C# timer

    - by Oak
    I'm trying to invoke a method f() every t time, but if the previous invocation of f() has not finished yet, wait until it's finished. I've read a bit about the available timers (this is a useful link) but couldn't find any good way of doing what I want, save for manually writing it all. Any help about how to achieve this will be appreciated, though I fear I might not be able to find a simple solution using timers. To clarify, if x is one second, and f() runs the arbitrary durations I've written below, then: Step Operation Time taken 1 wait 1s 2 f() 0.6s 3 wait 0.4s (because f already took 0.6 seconds) 4 f() 10s 5 wait 0s (we're late) 6 f() 0.3s 7 wait 0.7s (we can disregard the debt from step 4) Notice that the nature of this timer is that f() will not need to be safe regarding re-entrance, and a thread pool of size 1 is enough here.
