How to open one GUI from Another using a Pop-up menu

So I have a main GUI that I want to open up sub-GUIs.

On the main GUI I have 2 push buttons (Car and Boat) next to each other. Beneath them I have a Pop-up menu (one for each push button).

What I desire is once the user selects either the Car or Boat push buttons the relative Pop-up menu will activate with the different sub-GUIs (and their file paths).

The sub-GUI list will be the type of Car or Boat, which once selected the sub-GUI will open and the user has to put in the different data for depreciation, insurance costings etc.

I don't want to have to "poll" each sub-GUI if at all possible.

Why do you want the second GUI name in a popup menu if you want to active it immediately upon pushing the button? Anyway, you simple set the popup index in the callbacks. Let's say the string property for the popup was set in GUIDE with the strings 'CarGUI.m' and 'BoatGUI.m'. So then in the car button callback

% Set popup to index 1
set(handles.popup, 'Value', 1);
% Now launch the CarGUI function
CarGUI

And in the callback for the boat, you'd do

% Set popup to index 2
set(handles.popup, 'Value', 2);
% Now launch the BoatGUI function
BoatGUI

I don't think I explained myself adequately.

Once the Car button is pressed, I would like a list of car makers as independent sub-GUIs being Ford, Jeep and GMC listed in the Pop-up menu.

Once the user selects one of the car makers names in the list, that specific sub-GUI is launched.

Similarly, once the Boat button is pressed, have the boat manufacturer independent GUIs listed in the boats pop-up menu. Once the user selects the make of boat that corresponding sub-GUI will be launched.

I assume your popups are prepopulated with appropriate lists before the user clicks the button.

So in the button callback, you need to get the string and call eval() to run that string as a gui. Or better, since we like to avoid using eval, just get the popup's index and run the gui that you know you should run for that index. Like for the car button ....

index = get(handles.popupCar, 'Value');
if index == 1
    results = FordMustang; % Run FordMustang.m
elseif index == 2
    results = Corvette; % Run Corvette.m
elseif index == 3
    results = DodgeCharger;  % Run DodgeCharger.m
end

What command will load the subGUIs?

Using the 'Load" command with the file path does not work (the Main and SubGUIs are in different files).

I do not want to extract information from the subGUI into the MainGUI but rather use the MainGUI to open the SubGUI and run the SubGUI literally ontop of the MainGUI.

The commands inside the "if" blocks will run the subGuis. If you don't expect any results to be returned and simply want to launch an m-file called "FordMustang.m", then simply have

FordMustang

That will launch FordMustang.m and it should appear as the top most window. If you want it maximized in the Windows OS, in FordMustang's startup code, call MaximizeFigureWindow - Yair's function which I attach.

Thanks Image Analyst.

It works.
