Bug 20930 – Web Inspector: Show node description in inspector highlight

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Matt Lilek]

Especially once bug 17772 lands, it would be useful to display the "element#id.class" string from the breadcrumb bar on the node highlight itself.  We may not want it to be visible by default, but would definitely be useful with a modifier key.

I like this idea! Always visible seems fine, or always when in Node Search mode.

This simple request needs thorough UI design (cross-platform, title layout/font, etc.)

This is a suggested description appearance: <nodeName#id.class1.class2...classN> [offsetWidth x offsetHeight].

Timothy, could you have a look at it and suggest something wrt the UI/data presentation?

Some quick comments:

I think showing this note in the middle of the box would be better and be less likely to be clipped. If you show it in the middle I don' think it needs a box around it, maybe just bolder text or a text shadow.

Showing the node text in <> is odd, since it is an invalid tag when there is an id or class name. Just drop the <> or something smarter.

Don't use "x" for pixel size, use &times;. It is odd to give just one size, since there are multiple deminisions when padding and margin, what does this size include?

Thanks for taking a look!

Rendering the label in the middle risks obscuring border/margin rectangles for small elements (esp. narrow ones, should they have a lot of style classes) but I seem to have seen this approach elsewhere so this might work ok.
Without any background, it's going to be quite messy since it may overlay some existing text or image containing a similar pattern in the label area, even with a shadow (I've tried it out).

Yes, we were just sitting there experimenting, and this was one state snapshot. I don't know if there's something good we can use to enclose the text, guess should just drop the <>.

> Don't use "x" for pixel size, use &times;. It is odd to give just one size, since there are multiple deminisions when padding and margin, what does this size include?

This text is rendered in the native code (TextRun), so have to look up what &times; corresponds to.
This size includes [offsetWidth x offsetHeight]. Do you have any suggestions on how to layout multiple sizes/more data in this "tooltip" area?

The new screenshot addressed the "times" and element identifier format issues. Please speak up.

Web Inspector: prefix.

Use forward declarations instead.
