frameEntered -- Widget class

有了代理C++的世界真美好！

下列是application 应用中的帧切换事件：

//frame enter event initialize
void Widget::frameEntered(float _frame)
{
	//ToolTip is set false default!
	if ( ! mEnableToolTip ) return;
	
	IntPoint point = InputManager::getInstance().getMousePositionByLayer();
	//Check the ToolTip is not at the same point 
	if (mToolTipOldPoint != point)
	{
		//Initialize the tool tip hating time to start counting
		mToolTipCurrentTime = 0;
		//check the bounding box!
		//if the cursor pointer is in the widget range
		bool inside = getAbsoluteRect().inside(point);
		if (inside)
		{
			inside = false;
			//??how the InputManager get the mouse focus widget?
			//by what means
			Widget* widget = InputManager::getInstance().getMouseFocusWidget();
			while (widget != 0)
			{
				if (widget/*->getName()*/ == this/*mName*/)
				{
					inside = true;
					break;
				}
				// check the mNeedToolTip is true or false
				if (widget->getNeedToolTip())
					widget = 0;//widget->getParent();
				else
					widget = widget->getParent();
			}

			if (inside)
			{
				// just return the point
				size_t index = _getContainerIndex(point);
				if (mToolTipOldIndex != index)
				{
					if (mToolTipVisible)
					{
						mToolTipCurrentTime = 0;
						mToolTipVisible = false;
						eventToolTip(this, ToolTipInfo(ToolTipInfo::Hide));
					}
					mToolTipOldIndex = index;
				}

			}
			else
			{
				if (mToolTipVisible)
				{
					mToolTipCurrentTime = 0;
					mToolTipVisible = false;
					eventToolTip(this, ToolTipInfo(ToolTipInfo::Hide));
				}
			}

		}
		else
		{
			if (mToolTipVisible)
			{
				mToolTipCurrentTime = 0;
				mToolTipVisible = false;
				eventToolTip(this, ToolTipInfo(ToolTipInfo::Hide));
			}
		}

		mToolTipOldPoint = point;
	}
	else
	{
		bool inside = getAbsoluteRect().inside(point);
		if (inside)
		{
			inside = false;
			// проверяем не перекрывают ли нас
			Widget* widget = InputManager::getInstance().getMouseFocusWidget();
			while (widget != 0)

			}

			if (inside)
			{
				if ( ! mToolTipVisible)

						eventToolTip(this, ToolTipInfo(ToolTipInfo::Show, mToolTipOldIndex, point));
					}
				}
			}
		}
	}
