list_box

ListBoxes make use of a ListBoxRenderer. The default ListBoxRenderer simply displays an item’s string representation. To make your own ListBoxRenderer create a class that has a render_item() method that accepts the item to be rendered and returns a widget to render.

Here is an simple example of using the ListBox widget:

class MySys(bgui.System):
   def lb_click(self, lb):
      print(lb.selected)

   def __init__(self):
      bgui.System.__init__(self)

      items = ["One", "Two", 4, 4.6]
      self.frame = bgui.Frame(self, 'window', border=2, size=[0.5, 0.5], options=bgui.BGUI_DEFAULT|bgui.BGUI_CENTERED)
      self.lb = bgui.ListBox(self.frame, "lb", items=items, padding=0.05, size=[0.9, 0.9], pos=[0.05, 0.05])
      self.lb.on_click = self.lb_click

      # ... rest of __init__
