This might be interesting for you if you are programming Igor Pro user interfaces.

If you have ever tried to make your functions aware of subwindows, you might have missed a function that returns a list of all child windows of a (sub)window with full host specs. The built-in function ChildWindowList only returns "immediate subwindow window names", and does not include the full "host spec path".

print SubWindowList("graph0") prints something like graph0;graph0#G0;graph0#P0;graph0#P0#G0;graph0#P1
whereas print ChildWindowList("graph0") would print G0;P0;P1;

// return a (recursive) list of all child windows with full host specs
function/S SubWindowList(hostNameStr)
string hostNameStr
	string childList = ChildWindowList(hostNameStr), swList = hostNameStr + ";"
	variable n
	for( n = 0; n < ItemsInList(childList); n += 1 )
		swList += SubWindowList(hostNameStr+"#"+StringFromList(n, childList)) + ";"
	endfor
	return RemoveEnding(swList)	// necessary to avoid empty items
end
