Combo Box

The combo box widget allows the user to pick from a list of values. It has 3 bscript properties,

• Choices: The list of allowed choices. This is a list of pairs. The first element of each pair is the string that will be sent by the event() function when the user selects the choice, and the second is the text that will be shown to the user.

  Example

  [["1", "One"], ["2", "Two"]]

  The combo box will have allowed choices "One" and "Two".

• Selected: This expression should resolve to one of the allowed choices. It controls what is displayed as selected in the combo box. Even if the user makes a different selection, if this property doesn't update the selected item won't change.

• On Change: event() in this expression will yield the key of the item the user has selected. The handler should arrange to update the selected property to reflect the user's change.
