Does not work in MatLab 2016b

[burf2000]

I run launch and get

Error using getappdata
Value must be a handle.

Error in GridLayout/Update (line 282)
OldPosition = getappdata(Obj.Container,'Position');

Error in GridLayout>@(hsrc,ev)Update(Obj,true)

Error using GridLayout (line 70)
Error while evaluating UIContainer SizeChangedFcn

Undefined function or variable 'fHG1Client'.

Error in simiam.ui.AppWindow/create_layout (line 212)
jClient = jFrame.fHG1Client;

Error in simiam.ui.AppWindow/load_ui (line 72)
obj.create_layout();

Error in launch (line 20)
app.load_ui();

I get the same errors in matlab 2016a

I get similar errors in MATLAB R2019b (and a few warnings).

I appreciate it's been a while since this tool was developed (5 years!) so maybe shouldn't expect it to work today. How serious are these bugs and what would it take to update the code? (Happy to help if it's within my capabilities).

Actually there's a post about this error on the Mathworks help forum here:

There is one answer that recommends the following:

Change the code to jClient = jFrame.fHG2Client;

Somebody else explains:

The code is designed to work with Matlab's HG1 graphics. It will not run with modern Matlab versions. Ask the authors for instructions.

This seems to eliminate the last error.

I managed to hack my way past the immediate errors (see here for example) but then the UI launches and there are still lots of problems (e.g. text on buttons missing) so I guess this is going to be more than just a quick-fix:

@billtubbs Any luck getting the simulator fully working on a newer version of MATLAB?

[billtubbs]

@jtisaacs I was using version R2019b. I haven’t tried anything more recent.

I have it working now on R2020a. Beyond the fixes that you mention above I had to make changes to the AppWindow function to make the images show up on the buttons. The problem seemed to be with using img paths when I was using the html strings, so I switched to loading the image and setting the 'cdata' field.

@jtisaacs would you mind sharing how you fixed it? Maybe you can upload it to Github (or submit a pull request).
