C++ (Cpp) IsDisabledForEvents Examples

Example #1

File: HTMLButtonElement.cpp Project: Wafflespeanut/gecko-dev

nsresult

  aVisitor.mCanHandle = false;
  if (IsDisabledForEvents(aVisitor.mEvent->mMessage)) {

  // cause activation of the input.  That is, if we're a click event, or a
  // DOMActivate that was dispatched directly, this will be set, but if we're
  // a DOMActivate dispatched from click handling, it will not be set.

      // that means that if there are scripted submissions, the
      // latest one will be deferred until after the exit point of the handler.

Example #2
