qt - Best way to trigger a script for any change in one of several properties -

when bind property reevaluated if 1 of proprieties bounded changed. example:

property bool test: prcond1 || prcond2 || ... || prcondn

when status changed test reevaluated.

now... want similar triggering javascript function: when 1 of several conditions prcond1 || prcond2 || ... || prcondn changed want function called.

if there 1 status write:

onprcond1changed: { functioncall() }

but when take business relationship more 1 status best way it? there standard way?

basically need this:

functioncall() if 1 of these changes: prcond1 || prcond2 || ... || prcondn

where prcond's may of different types.

a possible solution grouping variables variant list , changes on list.

property var myobject = {'prop': 'value'} property variant conditions = [prcond1, prcond2, myobj] onconditionschanged: { console.log("one of conditions have changed"); }

note changes in properties of myobj not trigger changeevent, unless object changed (e.g. myobj = new object({'prop': 'newvalue'}) )
