Is there an easy way to execute a block of code when a dialog is closed or destroyed?
Also is there a safe, not performance destroying way to execute a bit of code everytime a specific node or couple of nodes are moved or deleted?
Do I use a callback for both of those? For the single node what would the callback event be?
Edit: I’ll be a bit more specific since that’s a bit vague.
I have a global variable which I want to be updated with the object’s current position whenever possible. Should I just do that through a position expression? But that would then control the object and it would be unmoveable … just thinking out loud here.
For dialogs, I don’t think there is any “global” way to track when they are closed. I tend to watch for the rollout close event and do my cleanup there

For a single node you could use
when <attribute> <objects> change[s] [ id:<name> ] [handleAt:#redrawViews|#timeChange] [ <object_parameter> ] do <expr>
(Thanks Bobo)
and
when <objects> deleted [ id:<name> ] [handleAt:#redrawViews|#timeChange] [ <object_parameter> ] do <expr>
Look up “Change Handlers” for more details on how to use it…
Just use the on <rollout> close event for when dialogs are closed. Since the dialog IS the rollout on a createDialog it’s the same thing.

Change handlers are probably the only way, unless you do some sort of script controller to check if somethings defined or not? Or check a weak reference? Change handlers are dangerous things – make sure you unregister it when you dont need it and give it an ID:#

Just the second one

Make a custom attribute paramblock (point3) and update it everytime the rollout closes?
on testRoll close do
(
testObject.pos.controller.'test attribs'.testval = testObject.pos
)
You could also use a change handler or a callback to update this variable too,
when transform $testObj changes do ID:#testHandler
(
testObject.pos.controller.'test attribs'.testval = testObject.pos
)
Perfect! Thanks guys.
I think I’ll do a hybrid of the two. A callback when the script interface is open and then shut it down when the interface is closed.
I’ve got a nifty new script I’ll be posting a prototype of probably by lunch.
Small modification to your code:
[left]when transform $testObj changes ID:#testHandlerID do (...)[/left]
[left]You had the ID after the do.[/left]
[left]Edit:[/left]
One small note… it doesn’t seem to update on every change of the transform but only the first transform. I guess it sort of lags one change behind.
