Ogre RenderWindow 的断言失败错误

Question

我正在尝试使用以下代码将 Ogre 嵌入 Qt： https://github.com/gklingler/QOgreWidget

它在我的系统上运行良好，没有任何问题，但是当我尝试在我的 Qt 应用程序中添加它时，我收到以下错误：

SceneManagerFactory for type 'PCZSceneManager' registered.
MovableObjectFactory for type 'PCZLight' registered.
MovableObjectFactory for type 'Portal' registered.
MovableObjectFactory for type 'AntiPortal' registered.
PCZone Factory Type 'ZoneType_Octree' registered
SceneManagerFactory for type 'OctreeSceneManager' registered.
app: ../app/ogre/ogrebasewidget.cpp:45: OgreBaseWidget::OgreBaseWidget(Ogre::Root*,                     OgreEventHandler*, QWidget*): Assertion `ogreWinId' failed.
The program has unexpectedly finished.

错误指向这段代码sn-p：

Ogre::String winHandle;

winHandle = Ogre::StringConverter::toString((unsigned long) (QX11Info::display()));
winHandle += " : ";
winHandle = Ogre::StringConverter::toString((unsigned long) (QX11Info::appScreen()));
winHandle += " : ";
winHandle = Ogre::StringConverter::toString((unsigned long) (winId()));

Ogre::NameValuePairList params;
params["parentWindowHandle"] = winHandle;
params["FSAA"] = Ogre::String("8");

int w = width();
int h = height();
mOgreRenderWindow = mOgreRoot->createRenderWindow("OgreWidget_RenderWindow",
                                                  qMax(w, 640),
                                                  qMax(h, 480),
                                                  false, &params);
mOgreRenderWindow->setActive(true);
mOgreRenderWindow->setVisible(true);

WId ogreWinId = 0x0;
mOgreRenderWindow->getCustomAttribute("WINDOW", &ogreWinId);
assert(ogreWinId);
QWidget::create(ogreWinId);
setAttribute(Qt::WA_OpaquePaintEvent);

我在标题中包含了<cassert>。帮我解决这个问题。 :(

我找到了它给出这个错误的原因。 我安装了旧版本（1.7.4）的 Ogre 以及新的 1.9 版本。

所以我从我的系统中清除了这个旧版本，瞧，它就像一个魅力。
