Class List

Superclasses :
gui::DropDown
Package :
gui

This component is for selecting one string from a list of several. When a button is pressed a list appears (possibly with a scroll bar) from which one item can be selected.

A SELECTION_CHANGED_EVENT is generated whenever an item is selected from the list.

Example :
l := List()
l.set_selection_list(["Red", "Green", "Yellow", "Blue", "Orange"])
l.set_size(120)
l.set_pos(100, 100)
l.set_selection(2)  # Green will be the first selection
self.add(l)
