    Description

      QComboBox has quite strange behavior with with model that changes dynamically. 

      After resetting model, the current index becomes -1 (even if there are some rows left in the model), but when another model was set to the combobox current index becomes 0.

      Check attached project for more details . QComboBoxStrangeBehavior.rar
