Designer plugins in Qt Creator

[stefan]

Hi,
I'm trying to use designer plugin in Qt Creator, but i can't figure out how to do it.
Where to put plugins .dll file? i tried to put it everywhere.

I installed windows SDK to try it out. dlls in "C:\Qt\2009.01\qt\bin" and in "C:\Qt\2009.01\bin" are not same size - is it possible that they are not compiled with same compiler? or what?

I've got the same problem, so I've rebuilt Qt, QtCreator and designer plugin (qwt) from sources using mingw32. After that additional widgets can be seen in QtCreator designer plugin widget list (Qt3Support widgets and Display widgets [Examples]). Arthur widgets [Demo] and Qwt widgets are available in QtDesigner only, despite corresponding dlls being in the same directory (C:\Qt\2009.01\qt\plugins\designer\). That seems strange to me.

it is a bit strange that they didn't compile Creator with same compiler as Qt library.
I wonder if linux version of SDK has same issue..

I tried the following:

1] download qt-creator-1.0.0-src.zip
2] open qtcreator.pro with existing Qt Creator
3] build release
4] run new qtcreator.exe
5] you have all designer plugins from C:\Qt\2009.01\qt\plugins\designer

They should fix this in 4.5.1, it's not even a bug, somebody just forgot to compile Qt Creator with right compiler..

Ok so this gets it compiled and running from within the installed QT Creator but if I copy everything that was built over to the correct directories in my installation, it gives me run error in QtCore4.dll:

The procedure entry point _ZN15ExtensionSystem13PluginManager11loadPluginsEv could not be located in the dynamic link library ExtensionSystem.dll.

Ok so the installed QT Creator was built using VS and the one I'm using was built with mingwin. I copy the required dll files from the /qt/2009.01/qt/bin directory into the build directory. These were built using mingwin. Now it runs outside of the /qt/bin/qtcreator.exe. Only problem is that the projects navigation widget is empty.

So now how do I get it running properly outside of the current QT Creator?

Only problem is that the projects navigation widget is empty.

How do you mean empty? When you open existing project or create new, it's still empty?

I figured it out. I was running from a build directory and I didn't have paths set to mingwin and qt bin directories. Once I copied the built exe and the rest of the built directory structure over to Qt/2009.01/qt/lib and Qt/2009.01/qt/bin, it worked. It even worked without having executable paths set.

Initially when I built qwt (5.2.0) and added the designer plug-ins to the plugin folder, QT (2009.02) told me they were win32-mingw instead of win32-msvc. After rebuilding QT Creator source using mingw, I see all the the other plug-ins noted in this thread but now it won't recognize the qwt plugin to any extent. I rebuilt everything in release mode. I know I'm a little bit closer since now when I build the qwt examples, they actually work (at run time anway. They can't seem to access qt4core.dll when I try to execute them individually). Anyone have any suggestions?

I have also added the path where qwt5.dll and libqwt5.a are located to Windows (XP Pro) PATH variable.

Thanks, I'll try your way. But I heard somewhere that QtCreator was built by VS2005. So it will not detect plugin not written by VS2005. I'm using 4.5.2 but have the same prob as yours.

Has this issue been fixed in later versions of Qt?

I'm running 2010.01 / 4.6.1 and might be getting the same issues. I can't get the designer to show my plugins in any lists and Stafan points out in the OP the DLLs are still different sizes
