Bug 162868 – [Modern Media Controls] LayoutItem and Button classes

• Component: Media
• Status: RESOLVED FIXED

[Antoine Quint]

Now that we have the basic building blocks to render content asynchronously with LayoutNode, we need to add a class to create buttons, which is the bread and butter of the UI part of media controls.

We will subclass Button a lot in coming patches, as it...

Why not use just a "" string here?

Would you ever want to call the delegate at this point?

Nice. I'd forgotten about this syntax.

This syntax is nuts. I really wanted to see buttonWasClicked: function (aButton)...

Nit: blank line isn't really needed

Sure.

The need for that hasn't arisen yet.

Yes, default parameter values and object deconstruction is a fine pair.

Sure, we can write it this way.
