GUI Examples #19:Explore popup selection determination and manipulation
Similar to GUI_18, except that the editbox is allowed to select a value from the popup. The editbox may also add an item to the popup.
function [] = GUI_19() % Demonstrate how to get selection from a popup to an edit box & vis versa. % This is an expansion of GUI_17. Here we will not enforce a specific list % of choices so that any text the user enters into the editbox will be % added to the popup list if it is not already there. % % % Author: Matt Fig % Date: 7/15/2009 S.fh = figure('units','pixels',...
