Bug 161945 – Web Inspector: Call Stack tree in the Debugger sidebar should mark the active call frame

• Component: Web Inspector
• Status: RESOLVED FIXED

[Matt Baker]

Summary:
Call Stack tree in the Debugger sidebar should mark the active call frame. Currently, there is no way to tell which call frame is active when another tree contains the selection.

Note:
Xcode shows an indicator (similar to the Inspector's instruction pointer marker) in the left side of the tree element. The indicator color depends on the parent tree element state:

Default = gray
Selected = dark gray
Selected|Focused = white

r=me, the video looks great!!

How does it look @1x? I assume as SVG it will look fine, but it would be worth checking out.
Should it have window inactive styles? My guess is no.

We should file a bug on GTK to add an Images/gtk/ActiveCallFrame.svg image and ensure they don't utterly break if the image is missing.

If the image is missing (GTK) will this throw a runtime error? If so, we will need to be graceful somehow.

It looks acceptable.

Correct!

Will do.

A "Failed to load resource" error is shown in the Inspector^2 console, but there are no other side effects.
