495818 - Zoom menu applies to the message pane rather than the browser in the selected tab

Status: RESOLVED FIXED

(Thunderbird :: Toolbars and Tabs, defect)

Description

[Mark Banner (:standard8)]

Now we have fixed bug 493700, we should be able to get menu options for per-tab specific functions.

The View -> Zoom functions currently only work for the message pane, not an iframe or browser in a different tab. We should fix this as some people may want to enlarge the text on What's New or about:rights to read it comfortably.

I knocked this up last night. The only bit I'm currently concerned about is the change from iframe to browser - need to work out what whether we need to add more attributes disabling various items or not.

Attachment: The fix

This patch fixes zoom and find to work with the content pane. Notes:

- I've switched the iframe to a browser and disabled the items I think we need to disable.
- We now toggle between content-targetable and content-primary for both the messagepane and browser elements in the content pane. This means that I've also changed GetMessagePaneFrame to get the messagepane rather than just window.content.
- The ZoomManager requires a "getBrowser" function. Therefore I've inserted an appropriate function into tabmail to allow that to work across different tabs without having to set a global variable.

Minor outstanding issues:

- The find option in the menu is called "Find in this Message".
- The find bar isn't shared with the one in the message pane. So the value for find again isn't shared between message pane and content tabs.
- The zoom options don't get disabled consistently for calendar, this is due to the way they override how we build our menus.

I think the first two issues can be dealt with later in follow up bugs, and the last one needs a bug raising on Lightning.

The fix

Looks really really good, so of course it's nitting time!

>+                   events="create-menu-view"
>+                   oncommandupdate="goUpdateMailMenuItems(this);">

That's some mighty funky indenting :)
