Detailed Description

Item delegate for rendering and editing the type of an initial parameter value.

This delegate provides a QComboBox editor allowing the user to switch between "scalar" (type 0) and "image" (type 1) as the source type for a model parameter's initial value. The type is encoded as an integer in the model data via the Qt::EditRole.
