1667081 - Remove noscript methods in nsIFocusManager

Status: RESOLVED FIXED

(Core :: DOM: UI Events & Focus Handling, enhancement, P2)

Description

[Edgar Chen [:edgar]]

https://searchfox.org/mozilla-central/rev/3d53187b90605ccef321c9cadbba762ad06a6381/dom/interfaces/base/nsIFocusManager.idl#261-303

nsFocusManager::GetFocusManager returns nsFocusManager*, native code could replace the usage of nsIFocusManager with nsFocusManager, cleaning up the interface a bit.
