C++ EndTransaction函数代码示例

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

本文整理汇总了C++中EndTransaction函数的典型用法代码示例。如果您正苦于以下问题:C++ EndTransaction函数的具体用法?C++ EndTransaction怎么用?C++ EndTransaction使用的例子?那么恭喜您, 这里精选的函数代码示例或许可以为您提供帮助。



在下文中一共展示了EndTransaction函数的20个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的C++代码示例。

示例1: GetTargetFrame

/* static */ bool
WheelTransaction::WillHandleDefaultAction(WidgetWheelEvent* aWheelEvent,
                                          nsWeakFrame& aTargetWeakFrame)
{
  nsIFrame* lastTargetFrame = GetTargetFrame();
  if (!lastTargetFrame) {
    BeginTransaction(aTargetWeakFrame.GetFrame(), aWheelEvent);
  } else if (lastTargetFrame != aTargetWeakFrame.GetFrame()) {
    EndTransaction();
    BeginTransaction(aTargetWeakFrame.GetFrame(), aWheelEvent);
  } else {
    UpdateTransaction(aWheelEvent);
  }

  // When the wheel event will not be handled with any frames,
  // UpdateTransaction() fires MozMouseScrollFailed event which is for
  // automated testing.  In the event handler, the target frame might be
  // destroyed.  Then, the caller shouldn't try to handle the default action.
  if (!aTargetWeakFrame.IsAlive()) {
    EndTransaction();
    return false;
  }

  return true;
