Ogre RenderWindow断言失败错误

Question

我试图使用at：https://github.com/gklingler/QOgreWidget提供的代码将Ogre嵌入到Qt中。

它在我的系统上运行良好，没有任何问题，但是当我试图在我的Qt应用程序中添加相同的内容时，我会得到以下错误：

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.

错误指向以下代码片段：

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);

我已经在标题中包含了<cassert>。帮我弄清楚。:(

Answer 1

我找到了这个错误的原因。我安装了Ogre的旧版本(1.7.4)以及更新的1.9版本。

所以我把这个老版本从我的系统中清除出来，看它就像一种魅力。
