GUI Examples #18:Explore popup selection determination
Explore popup selection determination and manipulation. Similar to GUI_17, except that the editbox is allowed to select a value from the popup.
function [] = GUI_18() % Demonstrate how to get selection from a popup to an edit box & vis versa. % This is an expansion of GUI_17. Here we will enforce a specific list of % choices so that any text the user enters into the editbox which is not a % choice in the popup will be overwritten. % % % Author: Matt Fig % Date: 7/15/2009 S.fh = figure('units','pixels',...
