527657 - Mouse move events are no longer sent when the app is inactive

Status: RESOLVED FIXED

(Core :: Widget: Cocoa, defect)

Description

[Markus Stange [:mstange]]

This stopped working when we switched to the 10.5 SDK.

Steps to reproduce:
 1. Click the desktop so that Firefox is no longer the active application.
 2. Right-click into the Firefox window in order to open a context menu.
 3. Move your mouse over the menu items and observe whether they're highlighted.

Expected results:
The items should highlight.

Actual results:
They don't, as of bug 501436.

This turned out to be rather simple.

The AppKit notes at http://developer.apple.com/mac/library/releasenotes/cocoa/AppKitOlderNotes.html#NSTrackingArea mention something called "NSDispatchMonitoredEvents" that can be set in some way, but I don't understand what to do with that. A Google search for NSDispatchMonitoredEvents turns up exactly one result: those AppKit notes.

Tweaked the comment a little to mention the SDK stuff, so that it becomes clear that it's fine to have the switch at compile-time, not at runtime.
