ComboBoxesA ComboBox is like a combination of an edit control and a ListBox. It can be displayed as static list with editable or read-only text field; or a drop-down list with text field; or a drop-down list without a text field.
A ComboBox permits a single selection only. ComboBox items are numbered from zero.
A ComboBox can run a Logo instructionlist when the user clicks with the mouse on an item and selects a choice, when the user changes the text or presses [Enter], and when any key event is received. The corresponding demo is comboboxtest.lg.
