25// TGComboBox, TGComboBoxPopup //
26// //
27// A combobox (also known as a drop down listbox) allows the selection //
28// of one item out of a list of items. The selected item is visible in //
29// a little window. To view the list of possible items one has to click //
30// on a button on the right of the little window. This will drop down //
31// a listbox. After selecting an item from the listbox the box will //
32// disappear and the newly selected item will be shown in the little //
33// window. //
34// //
35// The TGComboBox is user callable. The TGComboBoxPopup is a service //
36// class of the combobox. //
37// //
38// Selecting an item in the combobox will generate the event: //
39// kC_COMMAND, kCM_COMBOBOX, combobox id, item id. //
