  Hmm... Which version of Qt you are using to build the plugin ?
  http://bugreports.qt.nokia.com/browse/QTBUG-9287 would cause Kern-Exec 3.

  Also check that the buildkey doesn't contain compiler name and version. This issue was fixed at some point but didn't find the corresponding bug report. Symptom is that plugin fails to load.

  What that is confusing for you is just some notes before starting with Qt. There's no different between platforms to use with QtCreator. Then you need to have a little knowledge about configuring Qt for different platforms. Although you can download compiled binaries from http://qt.nokia.com
  then you can set the QtCreator environment to your desired SDK at Tools->Options->Qt4

  to compile for WinMobile and WinCE you'll need to have their SDK installed. After configuring your Qt for required version, you'll have to use QtAddIn under VS2008 to compile and deploy to your device.

  [quote author="SABROG" date="1294906845"]Why MeeGo using Clutter+Mx(widgets) instead Qt or QtQuick?[/quote]

  Meego only uses Clutter + Mx libraries for Netbook UX, Handset UX uses MeegoTouch which is based on Qt. The reason for using Clutter + Mx on Netbook I think it's because they're native UX libraries on Moblin. Nokia may still want to keep something "Intellish" or new Netbook UX has not been developed or being developed, but things might change in the future, who knows?

  Our support normally works via mail or IRC. I'd be the person to talk to

  I'm dalaing on #qt, #qt-labs and #qt-mobility on freenode, ususally available from 0830 to 1630 AEST (GMT + 1000).

  I asked about the licensing - since mapping is part of the 1.1 release it should be fine to use in a commercial product in general, although you probably need someone from your end to read and understand the terms and conditions associated with the Nokia mapping plugin if you're planning on using it in a commercial app, just in case.

  glReadPixels(0, 0, 320, 320, GL_RGBA, GL_UNSIGNED_BYTE, res.bits());

  I am using the VS console. here is the dump from the console command line:

  C:\qtmobility>configure -prefix C:\qt\4.7.1
  C:\qtmobility
  Checking available Qt
  4.7.1
  Checking make
  Cannot find 'nmake', 'mingw32-make' or 'make' in your PATH
  Aborting.

  i tried "configure -vc" with the same result.
  I tried from a standard command line and set the path variable with the following command:
  C:\qtmobility>set PATH=%PATH%;"C:\Program Files\Microsoft Visual Studio 9.0\VC\bin"

  same result.

  Well, the thread you read is correct. To display an & on a button, you have to double it to &&. The solution to your problem is therefore to un-double the && before you display it in a line edit. There are many ways to do this. One would be to simply do a string replace before pasting it on the line edit, where in replace a double && with a single &. Another would be not to use the caption of the button directly, but use another property instead. The latter would be a more flexible solution, I think.

  qtrahul,

  The device was updated to QT 4.7 using that of the Symbian^3 Developer Version and I installed the mobility 1.1 from file: qt-mobility-symbian-1.1.0-symbian3-nokia-signed.sis

  I did that update becuse the N8 was hard reset and I reinstalled the qt using the Qt_4_7_for_Symbian_3_Developer_Version_v1_0_en.zip

  Best way to manage UI layout in Qt
  • abhisag

  My opinion is that there is no generic Best way of "layout-ing" the widgets.

  In the end both methods are going to be C++ code (most likely very similar C++ code).

  The only big difference is who is writing the C++ code you write it, or the UIC generate it (using the designer xml as a "pattern").

  If you want to check this just open an ui_UIFILENAME.h and see the implementation of the setupUi(...) method.

  So to choose one way or the other, you need to think of what is convenient for you: the time you need to write the code for Widgets/Layouts vs the time you need to achieve the same result using Designer.
  Basically is the same for the application/code/compiler, it only depends on what is convenient for you: what are you most productive with, or what do you like, or maybe some simple dialogs (with simple layouts) are fast to code and some more complex layouts are easier to implement in the Designer.

  At this stage, you can make use of symbian native platform APIs for making call and other such telephony API requirements.

  Colman. I can't remember where but I read about what a thing was a similar issue (some key events that were always processed by "qt" and would never make to the event loops). The solutions was to deal with other event functions on QApplication, like:

  http://doc.qt.nokia.com/latest/qapplication.html#qwsEventFilter
  http://doc.qt.nokia.com/latest/qapplication.html#x11EventFilter

  Have you tried those?

  There was some other approach too but I can't remember what it was.

  You can try to add

  @
  LIBS += -Wl,-rpath,/opt/qt/qte-4.6.3/lib
  @

  This adds the lib path to your binary. See the end of the section 3.4 of http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html

  How is this related to Qt?

  QDesktopServices::openUrl() starts a browser pointing it to the URL given. What happens then is entirely up to the browser. Maybe you could check the javascript with other browsers and/or file a bug report against BrowserNG?

  Still can't start connection. I added qgenericbearerd4.dll into my application folder\bearer and now can see configurations.

  I have capabilities - 0x10, so seems that I can't start connection.

  Also I have list with 3 configurations:

  TNETW12511 - I guess wifi
  Automatic Tunneling Pseudo-Interface
  6to4 Pseudo-Interface

  when I'm trying to start I have error "The specified configuration cannot be used"

  When I switched on edge I've got one more connection - Cellular Line

  Anybody tryed to start internet connection from WinMobile with qt 4.7 application?

  Well yes, previously submitted applications - as in an application which is taken verbatim from your repository and just recompiled for some mobile target can't be submitted. Or, more specifically, it's a guideline: You can do that, but it shows no effort, and thus would be... More than very unlikely to win ;)

  Not recommended as it was TP and now it has been updated. There is a camera example available for Symbian at Forum Nokia. You will have to adapt it to use with Qt.

  Two approaches:

  you can use your .ui files for the individual pages. These can be designed in designer, and then loaded as pages for your sliding view. That should work just fine. You can extend the sliding-stacked-widget to a proper designer plugin. That way, you will be able to use it directly from designer itself.
