Use inputEnabledProperty

[pixelzoom]

For #137 and #139...

Any Node with an input listener will need to have its inputEnabledProperty instrumented. These Nodes can be identified by searching for addInputListener in the graphing-quadratics code. That includes:

• PointToolNode (point tools)
• All subclasses of GQManipulator (manipulators)

Is inputEnabledProperty read for general use? I have a request to use it in Graphing Quadratics to support disabling of draggable things.

Kathy Perkins 12:56 PM
@pixelzoom - My impression was it wasn't ready yet.

Michael Kauzmann 12:28 PM
My optimistic hope is by the end of next week.

Graphing Quadratics can wait for the pickable to be resolved, after the work for ■■■ study is completed. Yes, we will push back the date after we have a sense of when we figure out when pickable alternative is identified.

On hold and unassigned until phetsims/scenery#1116 is resolved and the PhET-iO team tells me that inputEnabledProperty is ready for use. @zepumph @samreid FYI.

Sounds good. This issue will be ready to go likely as part of phetsims/scenery#1158 though I can hold off on this repo is you would like. That issue is on hold until phetsims/scenery#1116 is sorted out.

FYI, there's no use of pickableProperty in this sim, which is the subject of phetsims/scenery#1158.

I interpret that to mean that we're going to wait to publish until inputEnabledProperty is ready, so labeling this issue as blocks-publication.

This is now ready for use. you can use inputEnabledPropertyPhetioInstrumented:true to instrument inputEnabledProperty instances in your sim.

Here's a description of the sim-specific inputEnabledProperty elements that were added in the above commits.

For point tools, there are 2 for each screen:

graphingQuadratics.*.view.leftPointToolNode.inputEnabledProperty
graphingQuadratics.*.view.rightPointToolNode.inputEnabledProperty

For manipulators:

graphingQuadratics.vertexFormScreen.view.vertexManipulator.inputEnabledProperty
graphingQuadratics.focusAndDirectrixScreen.view.focusManipulator.inputEnabledProperty
graphingQuadratics.focusAndDirectrixScreen.view.pointOnParabolaManipulator.inputEnabledProperty
graphingQuadratics.focusAndDirectrixScreen.view.vertexManipulator.inputEnabledProperty

@amanda-phet please review in master.

Looks like they are all there
