Bug 48760 – Web Inspector: highlight frame on hover in resources panel.

• Status: RESOLVED

• Component: Web Inspector (Deprecated)

[Pavel Feldman]

When I hover over a frame element in the new resources panel, I'd like to see it highlighted in the UI (i.e. its owner element is highlighted).

r+ with comments and a question about the early return in _onmouseout.

Nit: remove if the method gets removed.

I'd feel better if "m_inspectedPage->mainFrame()" was cached in a local variable. I never know when the calls are optimized out or not, and it might make readability easier here.

Nit: Adding a newline after the return would be nice.

In what cases does mouseout still have a node that is a descendant of the sidebar element? Is this like moving your mouse of the left edge of an undocked inspector?

Can be removed. Don't forget to remove from the ChangeLog as well.
