Re: [Qt-creator] Custom widget not showing in Qt Designer on Linux
OK, so I have found my $$[QT_INSTALL_PLUGINS]/designer directory and, indeed, the .so file is not getting put there. I can copy it from the source directory and then Qt designer does see the widget in the Rob's stuff location. It can't find the header file, so I just tried putting that in with the rest of the program project's source and I then get the following errors: /home/robertw/Software/Qt4/Qt4Test/ui_mainwindow.h:35: error: declaration of ‘rwLineEdit* Ui_MainWindow::rwLineEdit’ /home/robertw/Software/Qt4/Qt4Test/rwlineedit.h:7: error: changes meaning of ‘rwLineEdit’ from ‘class rwLineEdit’ /home/robertw/Software/Qt4/Qt4Test/ui_mainwindow.h:53: error: expected type-specifier before ‘rwLineEdit’ /home/robertw/Software/Qt4/Qt4Test/ui_mainwindow.h:53: error: cannot convert ‘int*’ to ‘rwLineEdit*’ in assignment /home/robertw/Software/Qt4/Qt4Test/ui_mainwindow.h:53: error: expected ‘;’ before ‘rwLineEdit’ Does that help in suggesting where the issue might be? Why would the .so file not be copied to the plugins directory? The widget itself seems to be compiling correctly! Thanks again, Rob Robert Wood wrote: I'm trying to get a very simple custom widget to show in Qt designer, but just can't get it to work, wondering whether anyone can help. In Qt Creator, I did File | New and chose Qt4 Designer Customer Widget. I gave it a name rwLineEdit then in the next box typed in rwLineEdit as the name of my Widget Classes. (Not really clear why this has to be done twice.) This then gives me all names of all the files such as rwlineedit.pri, .h etc and the plugin names the same but with plugin inserted. I chose my Widget Base Class as QLineEdit, fileld into some descriptions, includingstating a (non existent group - I'm assuming At designer handles that and makes a new one?). Next window only allows me to edit PlginName which I leave as rwlineeditplugin and the resource file as icons.qrc (again I left this). It adds a load of files and all seems well. I can add a routine to the class and compile it. The problem is, that when I launch Qt Designer it simply refuses to show up! From what I can see of the tutorials on how to do custom widgets the information seems to be in the source files. For example: Q_EXPORT_PLUGIN2(rwlineeditplugin, rwLineEditPlugin) Is at the bottom of rwlineeditplugin.cpp I have put all this in ~/Software/Qt4/customWidgets/rwLineEdit/ and I end up with a librwlineeditplugin.so file in there, but am thinking that should be somewhere Qt Designer looks at, which I thought was specified in: target.path = $$[QT_INSTALL_PLUGINS]/designer Would be really grateful if someone can point me in the right direction on this.

Re: [Qt-creator] Remote debugging armv5te using Qt Creator
Hi, I'm currently trying to debug remotely an application through gdb using Qt Creator. Majo had the same issue previously (http://www.mail-archive.com/qt-creator@trolltech.com/msg02532.html) but I don't know what was its final results. -- State of the art : I've gdbserver on my device and gdb on my host. Gdb is configured into Qt Creator (ToolsOptionsDebugGdb) without gdb startup script. My application is built using the right compiler (out of Qt Creator) My application is on the device. -- Procedure : I launch my application using gdbserver on the device : gdbserver host:port ./application I start debugging using gdb in Qt Creator : DebugStart DebuggingStart and attach to remote application (using i386 option) -- The architecture should match your target, i.e. arm. (Shouldn't matter though, since your cross-debugger doesn't not support i386 anyway.) Also, have you set the sysroot? And which version of Creator are you using? Log on the device console : [ ... ] /lib/ld-linux.so.3: No such file or directory.\n This looks to be the main problem. Again: Have you set the correct sysroot? Questions : 1 - Gdbserver is logging an error : gdbserver: error initializing thread_db library: version mismatch between libthread_db and libpthread and I have not this error when I'm debugging remotely without Qt Creator. I guess it is due to commands sent by Qt creator to gdb. How can we configure the commands sent by Qt Creator to gdb/gdbserver ? Which commands do you send to gdb when manually debugging? 2 - What is the purpose of gdb startup file and gdbserver startup file ? What is the syntax ? It's an sh script intended for doing preparations on the server side, like copying your program or starting gdbserver. See the email you referenced above for an example.

Re: [Qt-creator] Custom widget not showing in Qt Designer on Linux
Hi,
here is an extract from the documentation we are planning to add to shed some
light onto the Qt Designer plugin issue. I hope it helps:
...You can use Qt APIs to create plugins that extend Qt Designer. Qt Designer
fetches plugins from the standard locations and loads the plugins that match
its build key. For more information on how to create and locate plugins and to
change the default plugin path, see {How to Create Qt Plugins}.
Qt Designer is integrated into Qt Creator and in addition comes as a
standalone application. The correct folder to place the plugins depends on
which you use. The integrated Qt Designer fetches plugins from the
%SDK%\bin\designer folder on Windows and Linux and
QtCreator.app/Contents/MacOS/designer folder on Mac. Choose Tools Form
Editor About Qt Designer Plugins.
The standalone Qt Designer is part of the Qt library used for building
projects, located under %SDK%/qt. Therefore, it fetches plugins from the
following folder: %SDK%\qt\plugins\designer. To check which plugins where
loaded successfully and which failed, choose Help About Plugins in the Qt
Creator.
The Qt Creator that is included in pre-built SDK packages on Windows is built
with the Microsoft Visual Studio compiler, whereas the version of Qt shipped
for building applications is configured and built to use the MinGW/g++
compiler. Plugins built by using this version of Qt cannot be loaded by Qt
Creator because the build-keys do not match. The plugins can only be used in
the standalone version of Qt Designer. Choose Help About Qt Creator to check
the Qt version Qt Creator was built with.
If you want to use Qt Designer plugins that were built for the shipped Qt
version, you need to make sure that Qt Creator is built with the same compiler
by either recompiling Qt Creator using MinGW or recompiling Qt with Microsoft
Visual Studio, depending on which configuration you want to use for your
applications.

Re: [Qt-creator] Custom widget not showing in Qt Designer on Linux
Hi Friedemann,
Many thanks for that. It actually throws up questions!
Originally Creator was saying it couldn't find Qt Designer, so I
installed it [designer] from my (Mandriva) repositories and that works
fine other than with the customer widget. So, I wondered whether it was
this issue with different builds.
To be on the safe side I downloaded the latest sdk from the website and
have installed that, while uninstalling designer from the Mandriva
repositories.
With 2010.02 sdk installed, once again, I cannot launch designer from
creator. (By right clicking on the .ui file in the project explorer.) If
I reinstall designer from my repositories I guess I will be able to.
Creator just tells me:
'The application Qt Designer could not be found'.
I have put:
/opt/qtsdk-2010.02/qt/bin
in my PATH as that seems to be where designer lives. (I didn't
previously realise it was in the sdk.)
If I try and launch designer from the command line I get this error:
makekdewidgets(12371)/kdecore (KSycoca) KSycocaPrivate::openDatabase:
Trying to open ksycoca from /var/tmp/kdecache-robertw/ksycoca4
designer: symbol lookup error:
/usr/lib/kde4/plugins/phonon_backend/phonon_gstreamer.so: undefined
symbol: _ZN6Phonon12PulseSupport11getInstanceEv
Is there something I am missing here or is designer broken on Linux with
2010.02?
Thanks again,
Rob

Re: [Qt-creator] Custom widget not showing in Qt Designer on Linux
Hi Friedemann, This probably originates from Qt Designer trying to load a phonon plugin. Try to remove opt/qtsdk-2010.02/qt/plugins/designer/libphononwidgets.so and clear the environment variable QT_PLUGIN_PATH. If it still doesn't work, try to put /opt/qtsdk-2010.02/qt/bin as the first directory in the PATH. Well, I can now open designer from creator. I did have to put /opt/qtsdk-2010.02/qt/bin as the first directory in the PATH to finally get it going. However, I still have exactly the same problem in that the librwlineeditplugin.so file does not get put in the plugins directory. Again, I can manually copy the file to /opt/qtsdk-2010.02/qt/plugins, but I still get the same sorts of errors: /home/robertw/Software/Qt4/Qt4Test/ui_mainwindow.h:53: undefined reference to `rwLineEdit::rwLineEdit(QWidget*)' I should mention that I do have permissions for the sdk install directory. Just in case it's of interest: printenv QT_INSTALL_PLUGINS /opt/qtsdk-2010.02/qt/plugins I am not really convinced I had the wrong designer last time from the repository anyway, because both designer and creator were 4.6.1. I should maybe mention that I have successfully subclassed things like QPushButton and coded them into programs successfully, it's just getting this integration with Qt Designer that is proving elusive!

Not much, but it works for me.
Of course after this crash course on python I can say that I feel like
