【提问】qt中调用opencv的问题 [复制链接]

我在linux下用QT Designer做的主界面,调用opencv

    cvNamedWindow( "Image view", 1 );
    cvShowImage( "Image view", img );
    cvWaitKey(0);
    cvDestroyWindow( "Image view" );
    cvReleaseImage( &img );

用上面的代码显示出图像片后,后面的主界面就没响应的,而且关闭窗口时显示 窗口"<unknow>"没有响应
请各位大侠帮忙!!!!

楼主 我刚搞QT 多多交流 QQ 115435544 我经常遇到问题没人讨论 郁闷啊

应该是在cvWaitKey(0)停住了  因为cvWaitKey(0)无限等待

The cvWaitKey() function asks the program to stop and wait for a keystroke.
If a positive argument is given, the program will wait for that number of milliseconds and then continue even if nothing is pressed.
If the argument is set to 0 or to a negative number, the program will wait indefinitely for a keypress

请问楼主解决问题没有
可以请教一下吗？
