MATLAB: How to pass an argument in a CreateFnc in a GUI

createfcnguide

I want to pass an argument in a GUI's create function. The GUI opening function though is executed "after" the creating on the GUI. So, how do I pass an argument in a create function?

I want to create a drop down menu and the number of options is not constant, it depends on previous processing.

You don't. You do stuff in the OutputFcn(), not the CreateFcn(). OutputFcn is executed after the OpeningFcn. You can use global, or setappdata/getappdata(), or other ways described in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

Using a flag is perfect, but if ~(exist('flag') == 1) would be a very poor implementation. Remember that this would search in the complete Matlab path for the files 'flag.m', 'flag.mexw64', variables, Java classes, folders etc. also. This is slow and might not reflect what you need.

But adding a flag to the figure's ApplicationData is fine and secure:

flagIsSet = isappdata(FigureHandle, 'MyFlag');
setappdata(FigureHandle, 'MyFlag', true);
if flagIsSet
   % run your code, which should run once only
end
