How to get graphics array content App Designed

I have in a parent panel 4 push buttons and 2 children panels like this:

The number of children panels can vary, so I would like to read how many panels are. If I execute the command:

app.<Parent panel name>.Children, I get a graphics array of 6x1 (2=panels + 4=push buttons). Like this:

How can I read this cell array? Some equivalent to strcmp(ParentPanel,'Panel') to get an answer of an array like ([1 0 0 0 0 1]) and easily know with find command which members of the array are panels?

Thanks you in advance!

strcmp(get(ParentPanel.Children,'Type'),'uipanel')

Rather than searching for the panels after the fact, I'd probably create a property of your app that can contain a vector of handles to the panels.

When you create a panel, store its handle in that property.

If you delete a panel, remove it from that property.

When you need to operate on the panels, get that property and select the appropriate handle or handles from the vector.
