Bug 109434 – Web Inspector: Colorpicker not saving values

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

[Brian Grinstead]

When working on another case (https://bugs.webkit.org/show_bug.cgi?id=108852) I noticed that the colorpicker is no longer saving values.  If you click on the color swatch and open up the colorpicker, it will let you change the color in the popup, but the value never gets saved.  This is caused by the following line:

Source/WebCore/inspector/front-end/StylesSidebarPane.js

-                var scrollerElement = hasSpectrum ? self._parentPane._computedStylePane.element.parentElement : null;

This fixes it:

+                var scrollerElement = hasSpectrum ? self._parentPane._computedStylePane.bodyElement : null;

I'm working on a patch for this.

Patch to fix colorpicker save issue

Sorry if this is not in the correct format, trying to follow the guide for creating a patch and may not have done it right.

@Vlad:

I believe the issue is related to your recent changes to the sidebar structure. Could you see if anything else is broken in the StylesSidebarPane and MetricsSidebarPane (by plain looking at the code that may use the changed DOM elements)?

The solution suggested by Brian does not fix the broken behavior when the spectrum popup should follow the swatch when the sidebar pane stack is scrolled. Could you advise on the right solution?

Does the spectrum follow the swatch when the sidebar is scrolled?

[Brian Grinstead]

You are right, the popup does not follow the swatch while the sidebar is scrolled with the proposed patch.

Not saying that we *should* do this, but this code does cause everything to work: 

    var scrollerElement = hasSpectrum ? self._parentPane._parentView._parentView.element.parentNode : null;

The scroll event seems to now be happening on the div[class=split-view-contents split-view-contents-vertical split-view-sidebar-right].  Surely there is a better way to get that element from the stylessidebarpane than the way above, though.

Correct. That's why I was asking Vlad for advice. The new structure must have better accessors than ugly constructs like this one :)

Can the scrollerElement change while the color picker is active? (E.g. if the user resizes the web inspector window, which can alter the sidebar pane representation)

> Source/WebCore/inspector/front-end/StylesSidebarPane.js:1788
> +                    console.log("detached scroll listener from ", scrollerElement);

Please remove debug logging

> +                            console.log("attached scroll listener to ", scrollerElement);

Ditto
