// 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 //
// window. //
// //
// 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. //
// //
