Hi all, Is there guidance out there on how to best implement error handling in a guide-based GUI? I have a number of primary function that implement a try/catch and simply return the lasterror structure on failure. Back to the GUI, I insert the guidata but now what? I don't really want to put an active error check in each callback as I want something more implicit (that can be set to catch a failure of objects on the GUI as well). I can probably make something work in the primary call to the GUI (varargou = myGui(varargin)) but before I spend time doing that, I thought I'd check.
