There is no state; a trackItem is either present, or not. [Of course, you could set present trackItems to 0% opacity...]
Just for clarity, I'm referring to a sequence clip instance's "Enable" status, something which very much does exist at the UI level (e.g. the default Premeire Pro keyboard shortcut to toggle a sequence clip instance's Enable status is Cmd-Shift-E). A disabled clip, although present in the track, has no effect on the output.
Understood. There is still no state in the API.
Any reason setting the opacity (or volume, for audio track items) to 0 wouldn't work, for your use case?
Thx Bruce, I hear you.
Re my use case, I'm not trying to set the state, I'm just trying to get it... so my script can respect it's status (and ignore the item). Ah well. Would be great if some later version of the supported (or unsupported) API could expose that property. In the meantime I'll look at using an XML export to fill in the blanks.
