hey all,

i have installed qwt successfully.
i.e, i did following steps

cd qwt-5.2.1
qmake
make
make install

i copied

1. libqwt_designer_plugin.so libqwt_designer_plugin.so.debug these 2 files
from /qwt-5.2.1/designer/plugins/designer to /opt/qtsdk-2010.05/qt/plugins/designer

2. qwt-5.2.1/lib/* to /opt/qtsdk-2010.05/qt/lib

but still i cant see qwt widgets in list of custom widgets of qtcreator list so that i can drag and drop them on form.

could any one help
