18 // TGComboBox, TGComboBoxPopup //
19 // //
20 // A combobox (also known as a drop down listbox) allows the selection //
21 // of one item out of a list of items. The selected item is visible in //
22 // a little window. To view the list of possible items one has to click //
23 // on a button on the right of the little window. This will drop down //
24 // a listbox. After selecting an item from the listbox the box will //
25 // disappear and the newly selected item will be shown in the little //
26 // window. //
27 // //
28 // The TGComboBox is user callable. The TGComboBoxPopup is a service //
29 // class of the combobox. //
30 // //
31 // Selecting an item in the combobox will generate the event: //
32 // kC_COMMAND, kCM_COMBOBOX, combobox id, item id. //
