Detailed Description

Combo box widget for Kexi forms.

This widget is implemented on top of KexiDBAutoField, so as it uses KexiDBAutoField's ability of embedding subwidgets, it can display not only a line edit but also text edit or image box (more can be added in the future). A drop-down button is added to mimic native combo box widget's functionality.
