Class Description

                                                                      
 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.
