Bug 201470 – Web Inspector: unify the interaction of show/hide status icons in Sources and Canvas

• Component: Web Inspector
• Status: RESOLVED FIXED

[Devin Rousso]

Rather than "fading" the tree element's text when the underlying represented object is disabled/blackboxed, we should just "fade" the icon.  The "fade" shouldn't change when the tree element is selected, unless the user is hovering directly over the status eye (this helps convey the idea that clicking the status eye is like a checkbox).  The image of the status eye also shouldn't change depending on whether the underlying represented object is disabled/blackboxed, as it being visible/"faded" is already enough of an indicator.

It should also be possible to toggle the disabled/blackboxed state via the context menu.

We should set `this._disabled` immediately.

Currently if someone set the state rapidly before a response was received:

    shaderProgram.disabled = true;
    shaderProgram.disabled = false; // Wouldn't do anything.

Then the 2nd setting would potentially be missed and the frontend would leave the program in a disabled state, which would not be what we actually want.

This should be `super.ondetach()`

Given the superclass implementation is TreeElement, maybe this should call the super class if the specific case here is not true.

Does this show up very high in the context menu or rather low?

That's true.  I really wish we had a more "concrete" way of ensuring that frontend state is in sync with backend state, and only updating the frontend in response to changes from the backend (like how Timelines/Audit/Canvas all have this idea of "starting"/"stopping" when the UI has requested something and hasn't yet received confirmation from the backend).

Oops.

Good call!

It's basically at the very bottom, right above where the "Expand All"/"Collapse All" would be.  I'll move this to `WI.appendContextMenuItemsForSourceCode` instead, right under "Create Local Override:.
