Re: [Interest] Qt5 on MSVC2008, Win7x64 (Tier1)? (Charley Bay)
Date: Sun, 8 Jul 2012 12:56:32 -0600 From: Charley Bay charleyb...@gmail.com Subject: [Interest] Qt5 on MSVC2008, Win7x64 (Tier1)? As an aside, we've been watching the MSVC2012 Release Candidate that is out, it seems to solve some issues associated with MSVC2010, but drops native-targetting-for-XP (we don't care, but some might). Any thoughts about levels-of-support for MSVC2012? MS has announced that VS2012 will support native XP targeting in an update to be released a few months after it first ships. One reason to move forward from VS2008 is more C++11 support, such as 'auto', lambdas, etc. which are even in VS2010. I believe lambdas can be used as slots in Qt 5, which is long overdue, and you don't want to be left out because you're still using VS2008. -- David ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] Porting Qt app to windows
Date: Tue, 19 Jun 2012 13:08:07 +1000 From: Chasc ch...@tpg.com.au So how can I package this app to run on other Windows machines using dynamic linking? I have tried including QtGui4.dll, QtCore4.dll, libgcc_s_dw2-1.dll and mingwm10.dll libraries in the release directory but all I get is something about a procedure entry point not being located in QtCore4.dll. I am using Qt 4.7.4. It sounds like you're not including the correct QtCore4.dll, since the one being used doesn't have the missing entry point. Verify you put the correct DLL into your .exe directory. And verify that that is the QtCore4.dll being loaded into your running process, either by SxStrace.exe (Vista or later) or Depends (third party free app). Also I would try this on a PC (either real or virtual) that has a fresh Windows installed (and try all versions of Windows you need to support, e.g. XP/Vista/7) and make sure you are providing all the required DLL's (that are not present on a fresh Windows installation). Good luck, David ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] Porting Qt app to windows
From: Diego Iastrubni [mailto:diegoi...@gmail.com] Sent: Tuesday, June 19, 2012 8:22 AM I just rename the name of the Qt directory temporarily to _Qt or something and then rename back when I need to code... Ugly, but simulates uninstallation of Qt. But you also need to simulate the 'uninstallation' of the C runtime DLL's, etc. As well as making sure you set the compiler switches correctly and are not calling any native Windows API's that are not included in the lowest version of Windows that you are supporting. Really, there is no better way to test an app than on a fresh install of Windows. Thanks, David ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] Nokia SDK vs. Qt Commercial SDK
Thank you Konrad for the in-depth response, and also a shout to Andre. I much appreciate it. Now that I have a good idea of the current state, I must say I don't like the fragmentation that has occurred. When Nokia was in charge the LGPL/GPL was the same source as Commercial, and everything was included. Even before when Trolltech was in charge, the GPL was a subset of Commercial, but the subset that was there was exactly the same code. Now we are not guaranteed the same bug fixes (and eventually probably not even the same API's). I actually have several projects, some could go Commercial now, and some not. While I don't expect a major problem, it does mean multiple Qt versions installed to support all the different projects. I also miss the pre-built binary packages that used to contain the latest source releases, that were immediately usable, and in most cases, actually shippable. I needed to build Windows Qt because of SxS issues, but the Mac Qt was OK pre-built. As it happens, I am interested in taking the latest Windows Accessibility fixes in 4.8.2, and now I have to build all the platforms myself to get those. I do appreciate the promise that community contributions will have more impact now, and perhaps I will need to get more involved with that since that is what Qt is all about now. But coming from a Microsoft background, I really did like the support Nokia provided for free. You could almost forget Qt was open source, and now you cannot.

[Interest] Nokia SDK vs. Qt Commercial SDK
Hello, A couple days ago Turunen Tuukka from Digia responded to my question here about getting an SDK with Qt 4.8.2 in it by saying There is no Qt Project SDK for 4.8 - just the Nokia SDK and Qt Commercial SDK. Does this mean there are two official SDK's now, and the commercial one is different (i.e. with more bug fixes)? Where is this discussed, where do I learn about and get both? I must say, the state of what is available with Qt is as obscure as it was when Trolltech sold licenses to it and everyone had a different license price! I must be missing where such fundamental info is discussed. I admit I have been lost about the state and direction of Qt ever since I heard the term Open Governance. Could someone summarize what to expect? Thanks, David ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] Does it really worth it?
Date: Tue, 27 Mar 2012 21:58:32 + From: STEFANI Mathieu mathieu.stef...@supinfo.com Concerning chart libraries and Qt, Qwt has already been mentioned but I would like to mention KDChart (http://www.kdab.com/kdab-products/kd-chart/) as well, which is, to my mind, a better alternative than Qwt, since it's taking advantage of Model/View architecture and is really convenient to use, with a nice API. I'm using it on a personal project and I can say it's working very well. I would welcome a robust ecosystem of Qt UI libraries such as charting, docking frameworks, grids, etc. The fact that there is not one now (only a little bit) is a source of concern for me and in general the robustness of the Qt project. I had thought the situation would improve under Nokia, but it has not. By comparison, I am looking at what is available for .NET from vendors such as Telerik, SyncFusion, etc. Like the OP, I would also like to standardize on a development framework for the next three years. I have spent over 20 years developing Windows software using C++, so it seems highly possible to find something that will be robust enough to last for 3 years. But with more UI turning to web development (Javascript, jQuery,HTML5, etc.) or mobile (a lot of disparate tools here depending on platform), and what's left on the desktop turning to easier to use managed languages like Java and C#, it's hard to know which to focus on. Certainly Qt will play a part, but, it's cross-platformness not withstanding, it will be only a partial role.

Re: [Interest] QSerialport EV_RXCHAR not emitted or catched while moving window
Date: Fri, 16 Mar 2012 01:30:15 +1100 From: Tony Rietwyk t...@rightsoft.com.au Is this running on Windows? I seem to remember that the timers had the same problem - the events don't get delivered while the window is in resize mode. I never found a fix or workaround for this, and had to implement my own timers in a separate thread looping on sleep. I've experienced the same symptom (but was not able to diagnose why) using both QSerialPort and QExtSerialPort. If the window was dragged extensively, data loss would occur (characters would be unrecoverably lost). But the serial protocol had disabled any form of flow control (e.g. XON/XOFF, or hardware). So I blamed the problem on using a fragile serial protocol. Was this correct? If not, how are we supposed to use QSerialPort / QExtSerialPort reliably in a GUI app?

Re: [Interest] Qt Assistant can't search
Thanks, David. That's what I tried. I tried removing everything and adding it back. I tried removing everything, closing Qt Assitant, re-starting Assistant and adding everything back. I tried it more than once, and with some details thrown in like setting it to a blank page before removing everything. My search still doesn't work. I'm wondering if there's an index file somewhere that I can trash in order to force the index to be re-built. Hmm, I used the Windows utility Process Explorer to see which files Assistant.exe has open. Lookee there, e.g. C:\Users\David\AppData\Local\Trolltech\Assistant\qthelpcollection_4.7.4.qhc C:\Users\David\AppData\Local\Trolltech\Assistant\assistant.qch.4.7 Look in your Home directory for *.qhc and *.qhc. Try deleting the directories containing these files. Thanks, David ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] Qt Assistant can't search
Ah, hah! You do it from a terminal window, with a command-line option. On a Macintosh, since the .app is really a bundle directory, you do something like this: cd /qtbuild/install/macosx/bin/Assistant.app/Contents/MacOS ./Assistant -rebuild-search-index That's better than the hack I suggested before! :-) Glad you found it. I hope this type of thing is not indicative of a general decline of Qt. -- David ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
