Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

/**
|
|
* A few words on focus and focusrings
|
|
*
|
|
* We do quite a few hacks in the Downloads Panel for focusrings. In fact, we
|
|
* basically suppress most if not all XUL-level focusrings, and style/draw
|
|
* them ourselves (using :focus instead of -moz-focusring). There are a few
|
|
* reasons for this:
|
|
*
|
|
* 1) Richlists on OSX don't have focusrings; instead, they are shown as
|
|
* selected. This makes for some ambiguity when we have a focused/selected
|
|
* item in the list, and the mouse is hovering a completed download (which
|
|
* highlights).
|
|
* 2) Windows doesn't show focusrings until after the first time that tab is
|
|
* pressed (and by then you're focusing the second item in the panel).
|
|
* 3) Richlistbox sets -moz-focusring even when we select it with a mouse.
|
|
*
|
|
* In general, the desired behaviour is to focus the first item after pressing
|
|
* tab/down, and show that focus with a ring. Then, if the mouse moves over
|
|
* the panel, to hide that focus ring; essentially resetting us to the state
|
|
* before pressing the key.
|
|
*
|
|
* We end up capturing the tab/down key events, and preventing their default
|
|
* behaviour. We then set a "keyfocus" attribute on the panel, which allows
|
|
* us to draw a ring around the currently focused element. If the panel is
|
|
* closed or the mouse moves over the panel, we remove the attribute.
