New trackItem property in API - disabled - allows you to enable and disable clips (Beta)

[Dan McSweeney]

A new trackItem property - disabled - will be added in the next release, and is available for testing now in Beta version 22.0.0 build 130 and later. It allows for adding a boolean value to clip > enable, effectively allowing the API to flip the clip enable UI switch:

Once V22 ships, this will be fully documented in the Premiere Pro Scripting Guide, and a new button will be added to the Premiere Pro Sample Panel (SDK) , which will look a lot like this:

Code sample is below

enableAllDisabledClips : function () {
		var sequence = app.project.activeSequence;
		if (sequence) {
			var trackGroups 	= [sequence.audioTracks, sequence.videoTracks];
			var trackGroupNames = ["audioTracks", "videoTracks"];
			var updateUI 		= true;

			for (var groupIndex = 0; groupIndex < 2; groupIndex++) {
				$._PPP_.updateEventPanel(trackGroupNames[groupIndex]);
				var group = trackGroups[groupIndex];
				for (var trackIndex = 0; trackIndex < group.numTracks; trackIndex++) {
					var track			= group[trackIndex];
					var clips			= track.clips;
					var transitions		= track.transitions;
					var beforeSelected;
					var afterSelected;
					var initialSelectState;

					$._PPP_.updateEventPanel("track:" + trackIndex + "	 clip count: " + clips.numItems + "	  transition count: " + transitions.numItems);

					for (var clipIndex = 0; clipIndex < clips.numItems; clipIndex++) {
						var clip = clips[clipIndex];
						var name = (clip.projectItem === undefined ? "<null>":clip.projectItem.name);
						if (clip.disabled === true){ //using new trackItem property named disabled
							clip.disabled = false;
							$._PPP_.updateEventPanel("clip:" + clipIndex + " , " + name + " was disabled, is now enabled " );
						}	
					}
				}
			}
		} else {
			$._PPP_.updateEventPanel("no active sequence.");
		}
	},
