## Detailed Description

The dropdown list of a Combo.

A combo is a compound widget which crosses a text entry area and a pull down list. The dropdown list is implemented with the deprecated GtkList widget on the gtk+ side. ComboDropDown is a thin wrapper around GtkList containing just the functionality necessary for a Combo's list. To add and remove items use the STL-style interface that is accessible through ComboDropDown::children().

Deprecated:
  Use the ComboBox widget instead.
