In reply to Cameron Carroll. Hi, I know your post is 2 years old, but wondered it might help someone else with the same problem, since this information is not easily found on the internet. After loading your figure as a structure named 's', you should do:

struct2handle(s.hgS_070000,0,'convert');

That's how I accomplished it. Cheers, Augusto

I’m trying to use struct2handle to generate figures from a common base figure (loaded as a structure as per these blog posts) but I don’t really understand what to declare the parent as. struct2handle complains if I just pass it a struct, and the function itself doesn’t really return any meaningful error messages. [struct2handle(figstruct, gcbf) => ‘Caught unexpected error of unknown type.’]

I was just wondering what to pass in as the parent parameter, and whether anyone has an example.

Thanks a ton,

Cameron

In reply to Nievinski. @Nievinski - I personally think that these two functions will not be removed anytime soon. However, their internal implementation may indeed change. Also, I do not get any inside information from MathWorks, so I could be wrong in my assumptions.

I discovered recently both functions and started to use them. I’m developing a program with an interface that uses tabs, so to organize all the tabs is better to keep them isolated, so i’m using diferent figures and calling them in the main figure using handles2struct followed by struct2handle. Besides i’ll need this feature to some other tasks. Can you say about the chances of these function be removed in future releases? That would be disastrous for me.

In reply to matt dash.

On third thought, that still didn’t quite fix the problem. The saving worked, but I got an error when trying to re-open it, thus defeating the purpose of saving it…

I did end up fixing my original problem by making a simplified version of hgsave that uses handle2struct to get all the info that would normally be saved in a .fig file, and then I removed the references to the jtable before saving the stucture. Works like a charm!

In reply to matt dash. edit: Actually I also needed to ~ the "if SaveOldFig", so it is using hgsaveObject, not hgsaveStuctClass, when it works without errors.

As a mildly interesting related note, I just noticed that the problem I described here:

https://www.mathworks.com/matlabcentral/newsreader/view_thread/300680

Does not occur if I use the version 8 option in hgsave (by removing the ~ in “if ~feature(‘HGUsingMatlabClasses’)”) so that it uses hgsaveStructClass instead of hgsaveStructDbl.
