Scott - at what point does the second figure launch? Are you destroying/closing the first figure before opening the second, or are both open at the same time?
If just prior to closing the first, then you could access the selected value from the drop-down menu using its handle, popup, as
sels = get(popup,'String'); % get the list of bets
idx = get(popup,'Value'); % get the index of the selected bet
basebet = str2num(sels{idx}); % get the bet
If, however, you wish to use a callback, then consider nesting it within your Blackjack GUI main program. One interesting feature of nested functions is that they have access to the local variables defined in the main function/program. In this case, we could use the local variable basebet that the nested function would update or later use (for the second figure). Somethine like
function blackjack
% declare and initialize basebet
basebet = 25;
% create the figure with drop-down menu
figure;
popup = uicontrol('Style', 'popup',...
'String', {'10','25','50','20'},...
'Position', [15 90 100 50],'background','green',...
'Value',2,'Callback',@popupCallback);
% callback for the drop-down menu
function popupCallback(obj,event)
sels = get(popup,'String');
idx = get(popup,'Value');
basebet = str2double(sels{idx});
end
end
Any other nested function (similar to popupCallback) would then be able to use basebet in the same way.
