OpenCV + QT4

[thereisnoknife]

Hi Forum,

What's the good way to "display" an opencv's image (cv::Mat: same old IplImage ) in a QT-widget.

Thx.

I used for this QGLWidget and converted cvMat to QImage. Results were rather good and playback was seamless using timer event for update.

Also, forum search is your friend. This has been discussed many times.
