Ogre RenderWindow的斷言失敗錯誤

Question

我正在嘗試使用以下網址提供的代碼將Ogre嵌入Qt： https ： //github.com/gklingler/QOgreWidget

而且它在我的系統上運行正常，沒有任何問題，但是當我嘗試在Qt應用程序中添加相同代碼時，出現以下錯誤：

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.

錯誤指向以下代碼段：

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);

我已經在標題中包含了<cassert> 。 幫我弄清楚。 :(

我找到了給出此錯誤的原因。 我安裝了較舊的Ogre版本（1.7.4）以及較新的1.9版本。

因此，我從系統中清除了這個較舊的版本，瞧，它的工作就像一個魅力。
