Detailed Description

The ItemComboWidget class combines stack of widgets with QComboBox controller to switch between widgets.

It is used in the case when one SessionItem can be presented with different widgets. For example, in JobOutputDataWidget the results of the job can be presented with either IntensityDataWidget or FitDataWidget, depending from the JobView's activity type.
