  We report on the study of the population of B and Be stars in SMC young
clusters, performed with the Wide Field Imager in slitless spectroscopic mode
at ESO/T2.2m with a filter centered at Halpha. First, we explain the reduction
methods we used and our selection of different types of objects. Second, we
present results on the proportion of Be stars in SMC clusters, and we compare
this proportion to the one observed in the Milky Way. Finally, we also present
results on a statistical study of variability of Be stars with OGLE.
