覆盖/嵌入Firefox扩展中的插件SDK以修改panel.js

Question

I use the Addon SDK to display a Panel. It's working fine, but I would like to set the noautohide property to true , so the panel will not closed automatically when user clicks outside the panel.

I managed to access to the panel object using "chrome" authority but I am afraid of the red mark "experimental" ;-)

So I would like to edit panel/utils to expose the noautohide property. Is it possible to "override" or "embed" my edited file in the extension package?

Answer 1

Unfortunately, there is no supported way of doing this (that I know). Searching the SDK sources for noautohide without any results seems to confirm this.

Personally, I'd use the require("chrome") -and-get-the-XUL-element workaround for now (but keep in mind that there could be more than a single browser window), or just not implement it at all.

I would advice against patching the SDK and/or "embedding" a patched panel library.

The former would require to use a bundled SDK instead of the built-in SDK and seeing all the changes that go into each Firefox release, you'd likely have to re-package your XPI with every major Firefox update. Also you're not allowed to host add-on on AMO that bundle a patched SDK.

The latter option of "embedding" just the panel lib has the same maintenance problems. Also, it isn't exactly easy to extract/clone the just the panel library from the SDK... At the very least you'd have to clone sdk/panel.js and sdk/panel/*.js maybe even more.

It might be helpful if you filed a feature request .

Rather than patch it what you can do is as addEventListener for popuphiding and do event.stopPropagation(); and event.preventDefault(); . Then just add a close button that on click removes that listener and then hides the panel. I couldn't get arouund the noauthohide any other way:
