Multi window GUI, single file

Latest activity Commented on by Adam

I'm working on a user interface that relies on multiple figures, but each new figure implies new .m and .fig files, which will leave me with a lot in the end. How do I "compress" all these files into one single file?

I agree with Adam that a single file may be a lot harder to maintain. Speaking of hard to maintain: don't use GUIDE. Either use AppDesigner, or my guide below.
My small guide to avoid GUIDE:
  • Make a figure (with f=figure;) and look into the doc for figure which properties you want to turn off (you probably want to set Menu and Toolbar to 'none')
  • Create buttons and axes and everything you need with functions like uicontrol and axes. Save the handles to each element to fields of a struct (like handles.mybutton=uicontrol(___);)
  • When you've finished loading all data (and saving it to fields of your handles struct), and creating all the buttons, save your handles struct to the guidata of your figure like this guidata(handles.f,handles);. (You can also use getappdata and setappdata)
  • You can set the Callback property of many objects. If you do, use a function name with an @ in front, or a char array that can be evaluated to valid code. (like @MyFunction or 'disp(''you pushed the button'')')
  • Callback functions will be called with two arguments: the first is a handle to the callback object, the second is eventdata that may contain special information. To get access to your data, just use handles=guidata(gcbo);. You can replace the gcbo function with the name of the first input to your callback function if you prefer.
  • More information about callbacks can be found in multiple places in the doc, for example here.
While I agree to those answers, I'll say my workaround was to use MATLAB Compiler, to create a single .exe file that runs the multiwindow GUI App I was working on

If the other GUIs are launched from a main GUI then you only need to package the main GUI into an App anyway. I have done this plenty of times with multi-GUI apps. You just need a single entry point for the Matlab compiler. Indeed, I usually create a wrapper function for this purpose anyway which is not a GUI at all, but just launches my first GUI and does any other initialisation type stuff I need.
