Event.cpp A derived class might want to allocate its own type of aEvent (derived from WidgetEvent). To do this, it should take care to pass a non-nullptr aEvent to this ctor, e.g.: FooEvent::FooEvent(..., WidgetEvent* aEvent) : Event(..., aEvent ? aEvent : new WidgetEvent()) Then, to override the mEventIsInternal assignments done by the base ctor, it should do this in its own ctor: FooEvent::FooEvent(..., WidgetEvent* aEvent) ... { ... if (aEvent) { mEventIsInternal = false; } else { mEventIsInternal = true; } ... } 31237 91 %

EventDispatcher.cpp 62526 97 %
EventDispatcher.h About event dispatching: When either EventDispatcher::Dispatch or EventDispatcher::DispatchDOMEvent is called an event target chain is created. EventDispatcher creates the chain by calling GetEventTargetParent on each event target and the creation continues until either the mCanHandle member of the EventChainPreVisitor object is false or the mParentTarget does not point to a new target. The event target chain is created in the heap. If the event needs retargeting, mEventTargetAtParent must be set in GetEventTargetParent. The capture, target and bubble phases of the event dispatch are handled by iterating through the event target chain. Iteration happens twice, first for the default event group and then for the system event group. While dispatching the event for the system event group PostHandleEvent is called right after calling event listener for the current event target. 13416 100 %

EventNameList.inc This file contains the list of event names that are exposed via IDL on various objects. It is designed to be used as inline input to various consumers through the magic of C preprocessing. Each entry consists of 4 pieces of information: 1) The name of the event 2) The event message 3) The event type (see the EventNameType enum in nsContentUtils.h) 4) The event struct type for this event. Items 2-4 might be empty strings for events for which they don't make sense. Event names that are exposed as content attributes on HTML elements and as IDL attributes on Elements, Documents and Windows and have no forwarding behavior should be enclosed in the EVENT macro. Event names that are exposed as content attributes on HTML elements and as IDL attributes on Elements, Documents and Windows and are forwarded from <body> and <frameset> to the Window should be enclosed in the FORWARDED_EVENT macro. If this macro is not defined, it will be defined to be equivalent to EVENT. Event names that are exposed as IDL attributes on Windows only should be enclosed in the WINDOW_ONLY_EVENT macro. If this macro is not defined, it will be defined to the empty string. Event names that are exposed as content and IDL attributes on <body> and <frameset>, which forward them to the Window, and are exposed as IDL attributes on the Window should be enclosed in the WINDOW_EVENT macro. If this macro is not defined, it will be defined to be equivalent to WINDOW_ONLY_EVENT. Touch-specific event names should be enclosed in TOUCH_EVENT. They are otherwise equivalent to those enclosed in EVENT. If TOUCH_EVENT is not defined, it will be defined to the empty string. Event names that are only exposed as IDL attributes on Documents should be enclosed in the DOCUMENT_ONLY_EVENT macro. If this macro is not defined, it will be defined to the empty string. Event names that are not exposed as IDL attributes at all should be enclosed in NON_IDL_EVENT. If NON_IDL_EVENT is not defined, it will be defined to the empty string. If you change which macros event names are enclosed in, please update the tests for bug 689564 and bug 659350 as needed. 27217 97 %

However, if it puts too many logs like OnDestroyPresContext(), should long only when the method actually does something. In this case, the log should start with "<method name>". When a method quits due to unexpected situation, log the reason with LogLevel::Error. In this case, the log should start with "<method name>(), FAILED". The indent makes the log look easier. When a method does something only in some situations and it may be important for debug, log the information with LogLevel::Debug. In this case, the log should start with " <method name>(),". 110647 85 %

Therefore, this struct is declared in separated header file here. 2963 100 %
