class TGComboBox: public TGCompositeFrame, public TGWidget

TGComboBox, TGComboBoxPopup

A combobox (also known as a drop down listbox) allows the selection
of one item out of a list of items. The selected item is visible in
a little window. To view the list of possible items one has to click
on a button on the right of the little window. This will drop down
a listbox. After selecting an item from the listbox the box will
disappear and the newly selected item will be shown in the little

The TGComboBox is user callable. The TGComboBoxPopup is a service
class of the combobox.

Selecting an item in the combobox will generate the event:
kC_COMMAND, kCM_COMBOBOX, combobox id, item id.
