We have a set of Matlab-based tools that all use a common set of GUI superclasses to provide a consistent look and feel plus certain common functionality. They pre-date uifigure so use figure to create the GUIs. There are some features that are only available in GUIs created using uifigure, e.g. scrollable panels, plus the compatibility with the App Designer.

As a test I changed our superclass to use uifigure and encountered a pile of warnings and errors when testing with one of our tools. Obviously I can work through those but expect I will find the same in our other tools using the same GUI superclasses.

So, my questions are:

1) Is there a guide specifically for converting figure-based GUIs to uifigure-based? A checklist of what properties/methods are different even. I couldn't find anything.

2) Any experience/comments on how much pain is involved? If it was just one tool I'd go for it but it's a suite of tools in our case.

@Adam Danz -- Adam, I have to recant somewhat -- I have been comparing watching the app being used in the Foundation office in comparison to running it here and I cannot actually time the comparison there because MATLAB is not installed on those machines.

@Walter Roberson pointed out in another thread my supposition about JIT not being in play for the compiled app induced me to actually add timing code inside the app and I discovered that while it definitely is slower on those machines, on the same machine the two do perform very similarly...

Run  Compiled   Interactive Ratio
   41.65   31.35       1.32
   32.23   31.96       1.01
   32.36   31.47       1.03

was the result of that timing exercise, other than the first run the compiled code was a fair amount slower, the runtime otherwise is essentially the same.

So, if something could be done about the startup time and that seemingly interminable black hole after the double-click until finally!!! the splash screen appearsI(*), there wouldn't be much to complain about. <vbg>

(*) Even if there were only a spinning wheel or SOMETHING to let the user know it's working, it would go a long way. It's that big black hole of nothing that is so disconcerting.

Glad to hear this! I'll pass your comment along.

I've built no Windows apps from code other than Fortran console computational code so I don't know anything about normal app startup without the console, but commercial applications don't have such a delay before their splash screen appears as do the MATLAB compiled apps so I infer there must be some manner to make that occur while the code is doing whatever else it needs to do before rendering the user interface. The ladies have finally (sorta') gotten adjusted to the idea they just have to wait, but it is still disconcerting because one cannot tell if the application has actually been started or not for several seconds (that seem like forever) so the inclination is to try again and again and again...and, sometimes, the double-click didn't actually happen, either, so have sat around waiting until do finally decide that is what happened. It's just not a user-friendly experience to use these apps with this behavior.

This page gives an overview of the steps for updating: Update figure-based app to Use uifigure.

There's also more information on each step. For example, this page talks about replacing uicontrol with the newer UI component functions: Update UIControl Objects and Callbacks.
