Inspector should support point-and-click to select a node to inspect

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

[Adam Roben (:aroben)]

The Inspector should support point-and-click to select a node to inspect. This has a few advantages over the current "Inspect Element" context menu item:

1. It's clearer which node you're choosing, because the hovered node will be outlined before you choose it.
2. It's potentially more discoverable than "Inspect Element".
3. It doesn't require you to click on the node you're going to inspect, which could potentially change its state.

Bug 16532 covers a complimentary (and inverse) behavior.

Initial cut

As I wrote in the ChangeLog:

Despite putting this up for review, I'm not intending to land it as is. Among the known issues:
        - Need better art for the magnifying glass button
        - Is EventHandler really the best place for intercepting the node click - feels dirty. Would
          making -[WebView setHoverFeedbackSuspended:] cross-platform be a better route?
        - I think I can get away with not having to track searchingForNode in ElementsPanel
        - Some method names could be tweaked.

Hrm....git diff didn't include the button png....

This isn't much different from the previous version, but is more landable - ie: uses localizedStrings and also fixes a couple of bugs like stopping the search when you switch panels, but still does have a few bugs.

round 2

+    InspectorController* inspector = m_page->inspectorController();
+    if (!inspector)
+        return;
+    inspector->mouseDidMoveOverElement(result, modifierFlags);


Better written as:

if (InspectorController* inspector = m_page->inspectorController())
       inspector->mouseDidMoveOverElement(result, modifierFlags);

+    InspectorController* controller = reinterpret_cast<InspectorController*>(JSObjectGetPrivate(thisObject));
+    if (controller)
+        controller->toggleSearchForNodeInPage();

Better written as:

if (InspectorController* controller = reinterpret_cast<InspectorController*>(JSObjectGetPrivate(thisObject)))
      controller->toggleSearchForNodeInPage();
