qwt plugin with QtCreator in winXP

[Carlton]

I have installed qwt-5.2.0 along side Qt-Creator on my Linux machine (PCLINUXOS), and managed to get designer, when called from Qt-Creator to display the qwt widgets. However, on my PC at work, I can get the widgets to display if I open designer directly, but not if is opened from within Qt-Creator. Do the qwt plug-in .dll files need to go in a special place for this to work :confused:
Any hints gratefully received.

Hopefully, the post I replied in will help you out:

I was having the same problems.

Bah, I really should read posts AFTER I have my coffee. :)

There's a thread here discussing plugins in QtCreator. It looks like you may have to recompile.

I have solved my qwt plugin problem. My version of qwt was too old. I believe qwt>=5.2 is required.
Download qwt5.3, and build the release version.
copy the qwtdesigner... .dll file (I forget the full name, I only have XP at work:rolleyes:) into the designer/plugin directories. The qwt widgets now appear when designer is opened from QtCreator, just like in Linux.

I have the same problem.
I tried to start directly the designer. I can see the QwtWidget and also Arthur Widgets, Dispay Widget [Example] and Qt 3 support that comes with the standard installation of Qt SDK. None of these is loaded in qtcreator.

On linux I have copied libqwt_designer_plugin.so in qt/plugins/designer, bin/designer, lib/qtcreator/plugins. Maybe one of the is not necessary.

On windows I can't see nothing in QtCreator :crying:

I tried to compile QCreator from source code but I've got this error:

It looks like you're compiling QtCreator in debug mode when you don't have the Qt debug libraries installed. I've never compiled QtCreator from source, but it should be decently straightforward to compile just the release version.

As a side note, Qt-2009-02 Windows version comes with debug libraries as well, so maybe the debug libraries aren't in your path?

I don't know. I can compile my program in degug mode and they works.
Now I compile Qtcreator in release mode inside QtCreator and works fine. Previously I tried to compile with the Qt Command console.

Thanks.
