  • How to use custom drawing in QGraphicsViews in PyQt?

    - by DSblizzard
    I need to view QGraphicsScene in 2 QGraphicsViews with condition that they have different scale factors for items in scene. Closest function which I found is drawItems(), but as far I can understand, it must be called manually. How to repaint views automatically? I have these two code fragments in program: class TGraphicsView(QGraphicsView): def __init__(self, parent = None): print("__init__") QGraphicsView.__init__(self, parent) def drawItems(self, Painter, ItemCount, Items, StyleOptions): print("drawItems") Brush = QBrush(Qt.red, Qt.SolidPattern) Painter.setBrush(Brush) Painter.drawEllipse(0, 0, 100, 100) ... Mw.gvNavigation = TGraphicsView(Mw) # Mw - main window Mw.gvNavigation.setGeometry(0, 0, Size1, Size1) Mw.gvNavigation.setScene(Mw.Scene) Mw.gvNavigation.setSceneRect(0, 0, Size2, Size2) Mw.gvNavigation.show() _init_ works, Mw.gvNavigation is displayed and there are Mw.Scene items in it, but drawItems() isn't called.

  • How can I track an asp.net pages size without tracing?

    - by Middletone
    I want to be able to track the amount of data that is being transfered from my web site to each user that accesses the site. I can do this for file downloads and such but what about the pure html content itself. How can I track the output size of a page (or the data that's trasnfered via an AJAX call) to the client and log it against a particular users session? Also how would this differ when GZip is used in IIS 6.0?

  • scaleX scaleY increasing left, top margin, and line spacing

    - by Mark
    If you have Text with a font that is 72 point for example (and scaleX scaleY = 1) you can achieve the same size with a font size of 12 and scaleX,scaleY = 6. For reasons that would take too long to explain I am applying a large scale factor as in the latter example. The problem is, even though the text is the same size, the line spacing and left and top margins have all been increased but I want them to be the same size as well. As far as the line spacing, I discovered that TextFormat.leading was being automatically increased when scaleX, scaleY was greater than 1, so I just had to reset TextFormat.leading back to 0. That leaves the left and top margins, and I have no idea how those are being increased. I tried TextFormat.blockIndent=0 and TextFormat.leftMargin=0 (and also ignorePadding=true) and it had no effect. And have no clue how to reset the top margin either to its orginal size, in case anyone has an idea for all these.

  • Is a dedicated server similar in setup to a VPS?

    - by Dr Hydralisk
    I was thinking about getting a dedicated server (I may need the extra power that a VPS can't provide) from The Planet but I don't know to much about how you would operate one. I have experience in setting up multiple VPS's on Linode and Slicehost, I just select my OS in their CP and connect via SSH in putty and do my thing. Is it the same with dedicated servers (just chose you OS from the CP and connect via SSH and put on whatever crap you want)?

  • Safely get rid of "You have new mail in /var/mail" on a Mac?

    - by viatropos
    I was messing around with sendmail in Rails a year ago and have had this message popping up in the terminal after every command ever since: You have new mail in /var/mail/Lance How do I properly get rid of that so the message goes away? I ever use any of that functionality and don't have mail on my computer. There's one file in /var/mail called lance, and it's huge. Can I just remove it?

  • A service that turns doodles into PowerPoint?

    - by user1413
    I run a small business and need to create new PowerPoint presentations regularly. I find this to be an enormous pain. I'm not good at PowerPoint and creating PowerPoint is not part of my competitive advantage. What I would like to do is draw out the slides, scan them, and send them to a service that converts my doodles to PowerPoint. Is there such a service?

  • EE Major : Should I learn Ruby on Rails or Haskell?

    - by Vivek
    Hi,I've just completed my freshman year in college and am majoring in EE (with a lot of interest in CS as well) . I know some Python,C/C++ and Java and also a little bit of Actionscript . I am planning to learn either Haskell or Ruby on Rails. Haskell because it is a functional programming language, and I've been really impressed by this paradigm and Ruby on Rails , as I don't know any 'web' programming language and have heard that you can develop apps in RoR very easily and quickly . Which one should I learn ? and please suggest some links / books for starting off .

  • Unresolved import: models

    - by Timmy O' Tool
    Hi! I'm doing my VERY first project using python/django/eclipse/pydev following this guide http://docs.djangoproject.com/en/dev/intro/tutorial01/ My only addition is the use of Eclipse/pydev. I'm getting many errors related to "Unresolved imports". I can remove the errors using "remove error markers" and my site runs perfect (I can browse it) but I want to get rid definitively of this problem since errors appear again after I removed them. Any ideas?

  • F# working with DataReader

    - by mamu
    let getBytesData x = let len = reader.GetBytes(1, int64 0, null, 0, 0); // Create a buffer to hold the bytes, and then // read the bytes from the DataTableReader. let buffer : byte array = [||] reader.GetBytes(1, int64 0, buffer, 0, int32 len) |> ignore buffer let retVal = List [ while reader.Read() do yield (reader.GetString(0), getBytesData reader, reader.GetDateTime(2)) ] I have above code to read bytes[] from datareader. getBytesData function takes reader and returns bytes[] from reader. everything works fine but it getBytesData function is working very non-functional way. Is there any way i can optimize in F#? Sorry for kind of question, but i have started a new project on F# to squeeze all juice out of it, so trying to get each line most optimal way

  • Create a playlist in iTunes based on a hard drive folder

    - by Electrons_Ahoy
    I'd like to be able to base playlists in iTunes on a folder on my hard drive. For example, say I have this directory structure: C:\MP3s\Doctor Who Music C:\MP3s\Star Wars Music Importing all those MP3s into iTunes is really simple - at the bare bones version you can just drag the MP3 folder into the iTunes window and it does the rest. But, having done that, what I'd like to be able to do is point iTunes at each of those directories and have it turn them into their own playlists, so I end up with a Doctor Who Music and a Star Wars Music playlist based on the MP3s locations on the hard drive. Does iTunes have a way to do this, or is there a way to trick it into this with some other program? (I'm on Windows, but I'm sure Mac users would also appreciate answers to this as well.)

  • Dereferencing within a buffer

    - by kaykun
    Let's say I had a char pointer pointing to a buffer that contained these values (in hex): 12 34 56 78 00 00 80 00 I want to modify the last two bytes to a short value of 42. So I would think I would have to do something like this: (short)*(pointer+6)=42; The compiler doesn't complain but it does not do what I'm expecting it to do. Can someone tell me the correct way to assign the value?

  • Linking AS code to symbols defined in an external SWC?

    - by Ender
    (apologies ahead of time, I only really know Flash; my Flex experience is basically nil. There may be a very standard and obvious workflow solution that Flex people know about) I have a number of UI elements that are graphically quite complex (they're not components, they're just Sprites). Since it takes a long time to compile them, I've been trying to move them into an external .swc. However, I want to associate some code with these classes, but I don't want to have to recompile the graphical assets every time I make a code change. At the moment I have it set up like this: UI elements are created in a separate FLA and exported to a SWC. In my primary FLA, I have actionscript classes that extend each of the graphical assets in the SWC. For example: external.swc: (some symbol defined in the Library and exported for actionscript in frame 1) class: com.foo.WidgetGraphic base: flash.display.Sprite main.fla: Widget.as: package com.foo { public class Widget extends WidgetGraphic { ... } } This works, but is time-consuming and prone to error. I'd rather be able to avoid having to inherit from each graphical asset, and just define them directly. Is there a better way to do what I'm trying to accomplish? Note: the main concern here is compile time. I don't have any movies or audio or fonts, just a lot of vector art assets that appear to be slowing down my compilation time significantly. When I'm debugging I'm only making code changes, and would rather not have to keep recompiling the art...

  • problem running system.net.webclient and process.start off a control event

    - by Rob
    The following code causes my vs 2008 wpf project to hang, I'm not sure why. Both Part 1 and Part 2 work perfectly fine independently, but when I run them together on an control event (click a button for example) the program hangs. I've also tried shell execute for part 2 - same results. However, this code when run within the form loaded event works fine. Any insights would be truly appreciated. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click 'Part 1 Dim myWebClient As System.Net.WebClient = New System.Net.WebClient Dim CurrentDataFileContents As String = myWebClient.DownloadString("http://www.xyz.com") myWebClient.Dispose() 'Part 2 System.Diagnostics.Process.Start("http://www.test.com") End Sub

  • Call Web Service via BizTalk Orchestration via received file

    This example shows how some business logic can be implemented by receiving a file into a BizTalk Orchestration and calling a Web Service. The results of the Web Service call are decided upon from the contents of the incoming file and the response message is constructed accordingly. The response message is also saved down to the local file system.  read moreBy BiZTech KnowDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors?
