it is very simple but need to remind one point
for using qwt you don't need to see it in qt creator widget list(left panel) BECAUSE:
1- you can create your form in qt "Qt Designer" .
2. add form to your project.
3. customize project pro file.
4.Compile and enjoy.

first download qwt-6.0.0-rc4
from sourcefoge, if it is not same as above version not important.
Do this step by step
1.)copy and unzip download file in C:\qwt-6.0.0-rc4
2.)open “C:\qwt-6.0.0-rc4\examples.pro”
change “include( ../qwtconfig.pri ) “ =>
” include(qwtconfig.pri ) “
3.)Open “C:\qwt-6.0.0-rc4\ textengines\textengines.pro”
change “include( ../qwtconfig.pri ) “ =>
” include(qwtconfig.pri ) “
4.)Open “C:\qwt-6.0.0-rc4\ qwt.pro” with “Qt Creator” Compile it in DEBUG mode
5.)if you see only some worning it is usually so don’t care;
6.) After compile complete
7.)goto “C:\ qwt-build-desktop \plugins\designer\designer”
8.)Copy “libqwt_designer_plugin.a” and “qwt_designer_plugin.dll” paste to
“[Qt install path]\qt\plugins\designer”
9.)goto “C:\ qwt-build-desktop\lib”
10)copy “qwt.dll” to “[Qt install path]\qt\bin”
11)copy “C:\qwt-build-desktop\lib\*” to “C:\qwt-6.0.0-rc4 \lib\*”
Now you can use QWT Widget in your form at “Qt Designer”;
Now important place begin;
1.)create new project in qt and in wizard uncheck “Generate form”
2.)create your form in Qt Designer and save it in your project directory.
3.)Add Your designed form to your project.
4.)add this lines to your project pro file
INCLUDEPATH += C:/qwt-6.0.0-rc4/src
win32:LIBS += C:/qwt-6.0.0-rc4/lib/libqwtd.a
win32:QMAKE_POST_LINK = copy /Y C:\qwt-6.0.0-rc4\lib\qwtd.dll $(DESTDIR)
CONFIG +=qwt

If you run in debug mode red word stay
If you run in Release mode then “libqwtd=libqwt” and “qwtd=qwt”
Hi, I did as you said but on step 5) I get an error: "Failed to start application: Starting executable failed: J:/Name/qwt-build-desktop/qwtbuild.exe: No such file or directory."

Please help
