AsyncEventDispatcher.cpp mozilla::AsyncEventDispatcher **************************************************************************** 3989
AsyncEventDispatcher.h Use AsyncEventDispatcher to fire a DOM event that requires safe a stable DOM. For example, you may need to fire an event from within layout, but want to ensure that the event handler doesn't mutate the DOM at the wrong time, in order to avoid resulting instability. 5804

DragEvent.cpp 3998
DragEvent.h 2004
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; } ... } 26518
Event.h 13285
EventDispatcher.cpp 54292
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. 13339

EventListenerService.cpp mozilla::EventListenerChange **************************************************************************** 12626
EventListenerService.h 3265
EventNameList.h 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. 27192
EventStateManager.cpp / /* mozilla::UITimerCallback 243793
EventStateManager.h The PreHandleEvent method is called before event dispatch to either the DOM or frames. Any processing which must not be prevented or cancelled should occur here. Any processing which is intended to be conditional based on either DOM or frame processing should occur in PostHandleEvent. Any centralized event processing which must occur before DOM or frame event handling should occur here as well. aOverrideClickTarget can be used to indicate which element should be used as the *up target when deciding whether to send click event. This is used when releasing pointer capture. Otherwise null. 52805
EventStates.h EventStates is the class used to represent the event states of nsIContent instances. These states are calculated by IntrinsicState() and ContentStatesChanged() has to be called when one of them changes thus informing the layout/style engine of the change. Event states are associated with pseudo-classes. 14482
EventTarget.cpp static 6581
EventTarget.h This method allows addition of event listeners represented by nsIDOMEventListener, with almost the same semantics as the standard AddEventListener. The one difference is that it just has a "use capture" boolean, not an EventListenerOptions. 12245

GlobalKeyListener.cpp 27979
GlobalKeyListener.h A generic listener for key events. Maintains a list of shortcut handlers and is registered as a listener for DOM key events from a target. Responsible for executing the appropriate handler when a keyboard event is received. 6259
IMEContentObserver.cpp mozilla::IMEContentObserver **************************************************************************** 74144
IMEContentObserver.h OnSelectionChange() is called when selection is changed in the editor. 19328
IMEStateManager.cpp When a method is called, log its arguments and/or related static variables with LogLevel::Info. 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>(),". 78457
IMEStateManager.h IMEStateManager manages InputContext (e.g., active editor type, IME enabled state and IME open state) of nsIWidget instances, manages IMEContentObserver and provides useful API for IME. 19171
ImageCaptureError.cpp 1484
ImageCaptureError.h This is the implementation of ImageCaptureError on W3C specification https://dvcs.w3.org/hg/dap/raw-file/default/media-stream-capture/ImageCapture.html#idl-def-ImageCaptureError. This object should be generated by ImageCapture object only. 1647
InputEvent.cpp 4624
InputEvent.h 2050
InputEventOptions.h InputEventOptions is used by nsContentUtils::DispatchInputEvent() to specify some attributes of InputEvent. It would be nice if this was in nsContentUtils.h, however, it needs to include StaticRange.h for declaring this. That would cause unnecessary dependency and makes incremental build slower when you touch StaticRange.h even though most nsContentUtils.h users don't use it. Therefore, this struct is declared in separated header file here. 2990
InputTypeList.h This header file defines all inputType values which are used for DOM InputEvent.inputType. You must define NS_DEFINE_INPUTTYPE macro before including this. It must have two arguments, (aCPPName, aDOMName) aCPPName is usable name for a part of C++ constants. aDOMName is the actual value declared by the specs: Level 1: https://rawgit.com/w3c/input-events/v1/index.html#interface-InputEvent-Attributes Level 2: https://w3c.github.io/input-events/index.html#interface-InputEvent-Attributes 3907

KeyEventHandler.cpp 21999
KeyEventHandler.h Try and convert this XBL handler into an APZ KeyboardShortcut for handling key events on the compositor thread. This only works for XBL handlers that represent scroll commands. @param aOut the converted KeyboardShortcut, must be non null @return whether the handler was converted into a KeyboardShortcut 5796
KeyNameList.h This header file defines all DOM key name which are used for DOM KeyboardEvent.key. You must define NS_DEFINE_KEYNAME macro before including this. It must have two arguments, (aCPPName, aDOMKeyName) aCPPName is usable name for a part of C++ constants. aDOMKeyName is the actual value. 18640
KeyboardEvent.cpp 14516
KeyboardEvent.h ComputeTraditionalKeyCode() computes traditional keyCode value. I.e., returns 0 if this event should return non-zero from CharCode(). In spite of the name containing "traditional", this computes spoof keyCode value if user wants it. @param aKeyboardEvent Should be |*mEvent->AsKeyboardEvent()|. @param aCallerType Set caller type of KeyCode() or CharCode(). @return If traditional charCode value is 0, returns the raw keyCode value or spoof keyCode value. Otherwise, 0. 5221
