[quote author="Immii" date="1293550728"]Shadow build is possible only on mac and Linux[/quote] It is not true. I have just tested a working shadow build on my WinXP. I have configured against WinCE5 Standard_Sdk To test it i have create a very simple "hellp world" application. For details on the configure command and VS2008 compiler/linker option please cheack: http://developer.qt.nokia.com/forums/viewthread/2829

"Here":http://developer.qt.nokia.com/wiki/Mobile_Development_Performance_and_Internal_Application_Issues I created the new wiki for performance. Let us write down our ideas there

That's exactly what I have done - I put Qt 4.7.1. libraries on N8 and C7-00 and then I run the example. I have mde two builds (one against 4.7.1/S60 5th(S^1) SDK and one build against 4.6.3/S^3 SDK) and the result was much worse - applications crashes quite often, many things did not work and did not run faster as I believed... BR STeN[/quote] You can not put the Qt 4.7.1 in N8 , which already contain Qt 4.6.3. By doing this the application is going to be crashed, You have to wait for the official announcement for the update of the Qt library in Symbian^3 devices. [/quote] My applications are working with the developer version of the Qt 4.7 for Symbian^3 though.

@ -nomake examples -nomake demos @ Wanted those commands for a while. Thanks. I am going to build for WinCE i n the future to port my Mp3 plyaer on it. Hope I will able to help you.

[quote author="koshui" date="1293534906"][quote author="pazhs" date="1293114294"] We are using S60_3rd_FP2_SDK_v1.1, and hope we are using the latest version in this category and we tried the latest library available with N97 SDK ( but we are not sure whether its ARM built eexe.lib ) ... but the same error popped-up with the N97 SDk too. [/quote] Sorry for late answer... Christmas... I checked my 5.0 and N97 SDKs both of them had THUMB built eexe.lib. Sorry if I mislead you to think upgrading to those would work :S Good news is that Symbian3 SDK eexe.lib is built as ARM. I checked Forum Nokia Symbian3 0.8 SDK. Easy way to verify is to open the eexe.lib in your favorite text editor and search for "--thumb" or "THUMB" (upper case). If you don't find it then it is built for arm. [/quote] Hi thanks for your time and reply... As suggested by you, we tried the eexe.lib which is available with Symbian ^ 3 SDK... and it worked.... Thank you very much for your valuable time Happy Holidays and wish you a very happy New Year...

Oh, and another thing... Can you explain in more detail what was blocking you? It may be helpful for others finding themselves in the same situation.

I see and in the meantime I was reading about Magic Trackpad and Windows support, which is not that good :( While navigating through Google though, I found this one ("Bamboo Touch":http://www.wacom.com/bamboo/bamboo_touch.php) which might be interesting to you and might solve your problem, on which they are saying (I quote): bq. Bamboo Touch lets you add Multi-Touch input to any computer.

This cannot be achieved out of the box. The sizeHint approach might not work as expected, because it's only a hint, not a constraint. You could could create your own QHeaderView subclass and add the functionality there. You can add it to the table view with setHorizontalHeader().

[quote author="Prajnaranjan Das" date="1293434549"]Thanks for your reply... @QWidget *bgWidget = new QWidget(this); bgWidget->setObjectName(QString::fromUtf8("bgWidget"));@ Can you please tell me why are we using in the above coding [/quote] Line 1 creates the widget. This is a must. Line 2 gives the object a name, this completely optional. It's mainly used in debug output. It is completely different from the variable name, although often both are the same. [quote author="Prajnaranjan Das" date="1293434549"] @QString::fromUtf8("bgWidget"))@ and also tell me about this fromUtf8...[/quote] QString internally uses unicode for the strings. Unfortunately the world is not unicode in every place. Source code often contains only 8-bit strings. If your source code is in UTF-8 unicode, then you have to tell QString in order to do the right decoding. If you're not sure about Unicode and UTF-8, just ask a search engine - it is a quite big topic and would be out of scope for the Qt forum. Wikipedia would be a good start too.

Thanks for the advice. Also, i have the raised the question in Beta Testing Forum. Thanks, Sri

[quote author="QtK" date="1293446219"]I think Nokia does not allow applications distributed via OVI to accept payment from any other channel other than Nokia payment gateways. [/quote] I should reread the NDA again :D

You can explore the Qt Mobility API, if it doesn't provide all the required API you are looking for. You can always use Symbian API for getting such info.

The device you are using has Qt inbuilt and it is Qt 4.6.3. Phonon API was the deprecated API and it was used in Qt mobile extension project. (if I am not wrong) Instead you should use the Qt Multimedia API under the Qt mobility project.

Yes it seems to be similar, please try to avoid duplicate posts as much as possible.

[quote author="qtrahul" date="1293272908"]What about this article which is the same issue : http://wiki.forum.nokia.com/index.php/Qt_4.7_for_Symbian^3_-_developer_version[/quote] Hi Rahul, Strongly recommend you to go through both the links and find for yourself what the difference is.

[quote author="hisong1988" date="1293242389"]Hey, Merry Christmas to all people in this forum.[/quote] Merry Christmas!

If you want to add buttons you can do this in a method in your main class: @ void addButto() { QPushButton *button = new QPushButton(this); button->setText(tr("fancy button")); // add the button to a layout here connect(button, SIGNAL(clicked()), this, SLOT(fancyButtonClicked())); } @ Although it's hard to understand what you want to do in your user interface. It's makes a big difference if you show a button (that a user can click on) or if you show a label (that displays a bunch of text or image). And if you click the first button over and over, you get a big bunch of new buttons and labels... looks a bit weird to me. Also, the method that creates the new buttons or labels belongs into that class, that is the "controller" of your user interface or the respective part of it.

[quote author="welon" date="1292316911"]Hi I have run the exmaple codes of the "audioinput" from the Qt installation on my desktop, and it works well. But when I tried it a MeeGo IVI version 1.1, it can not work. Does any body have similar experience or know what is th reason? Thanks so[/quote] Try now with Qt Mobility 1.1.2 Tech Preview. It seems to be more focused towards Meego so might help you.

Please, show some code snippets to allow us understand better your problem.

[quote author="abhi.dhiman83" date="1293091323"]Hi Tobias, Thanks for you reply. Would help a bit more. Actually I am very new to QT, So it would be a great help to me if you can provide some example of how to sort a sqlite database table using Qstring::localeAwareCompare. Thanks in Advance Abhi[/quote] Abhi, Its Qt and not QT.
