Hi everyones,

Could I trigger an event or catch a message when user is changing MinTime and MaxTime in document ?
It is possible to Catch it also when he changing the FPS ?

This is to force update of my tag deriver from TagData !

Many thanks in advance 😉

this has been discussed in the Python subforum some time ago in the "Preview Min Time" message thread.
You can listen to EVMSG_CHANGE and then compare the parameters you are interested in.

can you please let me know, in which context you are using above message ID. It doesn't seem to work for me here.

I think, you have to recheck your code.
My assumption is, that it works for you only, because the tag, or the object it's attached to, was selected, while you tested it.

1073741828 is actually MSG_MULTI_MARKMATERIALS and at least here on my system, I don't get this on changes of preview min/max time or any related values.
