300152 - Switching to another application while a custom tooltip is visible (via the |title| attribute) causes Camino to hide the current browser window.

Status: RESOLVED FIXED

(Camino Graveyard :: General, defect, P2)

Description

[Wevah (Nate Weaver)]

Summary pretty much says it all. I can reproduce this consistently on the
Mozilla products page (above) by mousing over the header graphic and waiting for
the tooltip to appear, then hitting Command-Tab. Sometimes it'll even happen
after the tooltip has gone away, if I immediately switch to another application
by clicking its icon in the Dock.

This might be related to our custom tabs now being child windows (bug 245019).

Yeah, this is a child window thing. Odd.

The bug was that we were using an NSPanel for the tooltip, for which
-hidesOnDeactivate is YES by default. But if you hide a child window, its
parent window gets hidden too.

The fix is to make the tooltip an NSWindow, and manually register for
NSWindowDidResignKeyNotifications so we can hide the tooltip then.
