When I code in SoQt\Coin\Qt environment, I encounter this failure during the app startup.
The Error's infomation just like the following which I copy ,from the DEV Net @ qt.com, and my issue is almost same. You can check the discussion from here.
ASSERT failure in QCoreApplication::sendEvent: “Cannot send events to objects owned by a different thread. Current thread 2be7670.
Receiver ‘’ (of type ‘QWidget’) was created in thread 2306c00”, file kernel\qcoreapplication.cpp, line 305
almost half a day I paid to solve this issue and find out the causing reason. It occurs when you run a debug version of the application using a release version of the 3rd-part-dll (such as SoQt/Coin 's dll), or when you run a release one using a debug version of the 3rd-part-dll.
Make sure the application's compiling configuration is according to the 3rd-part-dll really used .
If your problem cannot be solved , and it occurs during running the application, not the starting process, the failure maybe caused by sending cross-thread event in your program , you can see more about this field from the article here .
在SoQt\Coin\Qt環境下碰到 “不能跨線程發送事件”的錯誤
可能原因： 編譯鏈接的錯誤
解決辦法：使應用程序生成版本的配置（release或debug）與所使用的第三方組件的生成版本一致。
其他原因：Qt程序中跨線程發送事件
解決辦法：請參考Qt的專題討論文章，或者CSDN Qt開發者專區《如何釋放線程中創建的對象》
