For that i have downloaded Qwt 5.0.2 and installed successfully.But i was unable to find plugin of qwt in Qt designer.

Anyone please try to help me in plugging Qwt with Qt

Use Qwt 5.2 ( all Qwt 5.x releases work with Qt 3.3 ) and use the search function of this forum, that is full of threads about using the designer plugin on Windows.
