What's the complete structure of a figure handle object?

Question

Mathworks has done it again: my ancient R2012 (as bestowed by my company) returns a nice set of doubles identifying the figure window numbers in response to

currhandles=findall(0,'type','figure');

Now I got a fellow remotely IM-ing me 'cause the code I gave him fails under R2015 because findall now returns a structure for the figure handle. I can't play w/ his system (no RDC) and the mathworks documentation pages don't appear to specify the elements of the figure handle structure. In particular, I'd like to know if I can still retrieve the figure window number. Anyone know?

Answer 1

Of course.

currhandles(:).Number

will return all numbers as a comma-separated list.

Or specify a number you want:

currhandles(1).Number

The order appears to be the inverse order of initialization.

Alternatively you can define two anonymous functions to get an array directly:

figure(1); figure(2); figure(42);

getNumbers = @(x) [x.Number];
getFigureNumbers = @() getNumbers([findall(0,'type','figure')]);

getFigureNumbers()

ans =

    42     2     1
