In JSL, is it possible to identify a selected (or clicked-on) box in a diagram?

[#1]

Hi,

I click on a box in a hierarchical diagram.

How can I know (using JSL) which box has been selected?

Thanks.

Shaul.

Ok... It seems to be an elegant solution to the lack of an inherent open/close possibility. I got it and will try it and will inform asap.

As I mentioned before, the need is to manipulate the visibility of parts of a diagram.

Thanks again.

OK! it works. Thanks a lot. Here's the JSL that swiches "h2" on and off.

namesdefaulttohere(1);
shw2=1;
w=newwindow("w",
	h1=hierbox("h1",
		b2=buttonbox("b2",
				shw2=1-shw2;
				h2<<visibility(
					if(shw2==0,
						"hidden",
						"visible"	
					)
				)
					
		),
		h2=hierbox("h2",
			h3=hierbox("h3")
		)
	)
);
h1<<ChangeType("hierarchy");
